ProgressBar — Индикатор прогресса

Основы

Компонент ProgressBar (Индикатор прогресса) применяется в тех случаях, когда пользователю нужно показать, что программа не зависла, а выполняет продолжительную работу.

Находится в категории Widgets.

Студия предлагает несколько видов индикаторов: ProgressBar и ProgressBar (Horizontal). В свою очередь компонент имеет несколько модификаций и их отличия заложены в стилях, если посмотреть XML-описание компонентов. Стили постоянно меняются, поэтому проще выбрать атрибут style и посмотреть предлагаемые варианты из выпадающего списка на текущий момент.

Методы для работы с ProgressBar:

• setProgress() — устанавливает заданное значение индикатора прогресса;
• getProgress() — возвращает текущее значение индикатора прогресса;
• incrementProgressBy() — устанавливает величину дискретизации приращения значения индикатора;
• setMax() — устанавливает максимальное значение величины прогресса.

Круговые индикаторы Normal, Small и Large можно просто разместить на экране, и они будут бесконечно выводить анимацию вращения без единой строчки кода.

Как правило, «бесконечный» индикатор выводят в нужный момент, а когда задача выполнена, то его скрывают. Видимость можно установить через XML и программно.

В коде используется метод setVisibility()

Сейчас проекты в студии используют Material Design, поэтому цвет индикатора будет соответствовать ресурсу colorAccent.

Можно переопределить цвет, если вы хотите отказаться от этой связи с colorAccent, задав свой стиль.

Подключаем через тему.

Другая настройка связана с Tint — оттенками цвета (Android 5.0).

Стилизация

Если вам не нравится внешний вид стандартных индикаторов, то можете придумать свой. Есть два варианта для реализации этой цели. В первом случае можно подготовить готовый png-файл (spin_custom.png) и поместить его в ресурс, например, в папку res/drawable.

Затем в этой же папке создаём xml-файл spinner_png.xml с таким содержанием:

Теперь в разметке активности можно определять ProgressBar так:

Если запустить проект, то увидим такой индикатор:

В реальности индикатор выглядит немного корявым, подёргиваясь на экране. Кроме того, изображение можно улучшить, уменьшив количество цветов и сократив размер файла.

Второй вариант выглядит предпочтительней. На этот раз мы обойдёмся без графических файлов, а будем использовать только XML-разметку. В этой же папке поместим файл spinner_ring.xml следующего содержания:

Теперь в разметке активности пропишем строки:

Получим следующий результат:

Индикатор с текстом

К сожалению, индикатор не выводит текст во время работы, что не очень удобно. Можно создать свой ProgressBar из TextView или создать свой компонент на основе ProgressBar. Другой простой способ — наложить текстовый блок прямо на индикатор, используя RelativeLayout. Пример для пояснения.

Код, чтобы увидеть работу индикатора. При каждом щелчке кнопки значение индикаторов увеличиваются на 10 процентов.

Индикаторы прогресса также можно использовать в заголовках приложения у старых устройств, а также в ActionBar и ToolBar у новых устройств.

Компонент постоянно дорабатывается. Например, в Android 8 появились новые методы isAnimating(), getMin(), setMin().

Анимация ObjectAnimator

Можно подключить готовую анимацию для визуализации компонента.

Кастомизация ProgressBar в Android

Периодически возникает потребность заменить стандартный круговой ProgressBar на какой-либо свой.

Обычно визуальное восприятие у людей более обострено, так что сразу приведу пример нескольких вариантов ProgressBar

На хабре обсуждались некоторые ресурсы генерации прелоадеров, можно использовать их для создания изображения, которое в последствии попадет в ProgressBar.

Для кастомизации ProgressBar’a нужно выполнить несколько вполне тривиальных шагов:

1. Создать Android проект
2. Добавить в проект файл, содержащий loader (например res/drawable/loader1.png)
3. Создать файл анимации (например res/drawable/loader1_progress.xml)

1. xml version =«1.0» encoding =«utf-8» ? >
2. animated-rotate xmlns:android =«schemas.android.com/apk/res/android»
3. android:drawable =»@drawable/loader1″
4. android:pivotX =«50%»
5. android:pivotY =«50%»/>

4. Разместить ProgressBar в Активити и сказать чтобы использовал наш ресурс анимации, созданный на предыдущем шаге (например res/layouts/)

1. xml version =«1.0» encoding =«utf-8» ? >
2. LinearLayout xmlns:android =«schemas.android.com/apk/res/android»
3. android:layout_width =«fill_parent»
4. android:layout_height =«fill_parent»
5. android:orientation =«vertical» >
6. ProgressBar
7. android:indeterminateDrawable =»@drawable/loader1_progress»
8. android:layout_height =«50dp»
9. android:layout_width =«50dp» >
10. ProgressBar >
11. LinearLayout >

Кроме использования готовых изображений лоадеров, можно также использовать функционал android для создания лоадера вручную (например /res/drawable/custom_progress.xml)
Рассмотрим на примере фигуры кольца. Цвета указаны в формате #aarrggbb, где аа указывает значение альфа (прозрачность).

1. xml version =«1.0» encoding =«utf-8» ? >
2. animated-rotate xmlns:android =«schemas.android.com/apk/res/android»
3. android:pivotX =«50%»
4. android:pivotY =«50%» >
5. shape android:shape =«ring»
6. android:innerRadiusRatio =«5»
7. android:thicknessRatio =«6»
8. android:useLevel =«false» >
9. gradient
10. android:type =«sweep»
11. android:useLevel =«false»
12. android:centerY =«0.10»
13. android:startColor =»#0020ffcc»
14. android:centerColor =»#8820ffcc»
15. android:endColor =»#ff20ffcc»/>
16. size android:width =«18dip»
17. android:height =«18dip»/>
18. shape >
19. animated-rotate >

Если у нас имеется несколько изображений одного ProgressBar

то можно воспользоваться следующим способом (например /res/drawable/custom_progress_blue.xml):

Circular Progress Bar Android Tutorial [4 Easy Steps]

Welcome to Circular progress bar android Tutorial. In android development Progress bar is widely used and in many forms but one that is arguably the most loved is “Circular Progress bar with text”.

If you have been in android development for even a couple of months you have at-least once wondered how can I get a progress bar with text progress well you are in luck cause we are going to do just that in this tutorial as shown in picture and possibly a little more.

Circular progress bar with text in android is pretty easy to make and takes like 4 easy steps to do just that but before we dive right in let’s take a look at what it actually is.

What is a Progress bar?

An UI element that signifies that a process is executing and shows progress as its name would suggest. Progress bar in general supports two modes to represent progress.

• Determinate (By Default Linear)
• Indeterminate (By Default Circular)

Indeterminate Progress Bar

One example of this can be the very default Progress Bar we have now the circular motion with an animation we can consider using these kinds of Progress Bar when an operation under execution and we wouldn’t know how long that would take.

A great and most familiar example of this can be an api endpoint call we would not know what can happen until we get a response. Using an indeterminate Progress Bar here makes sense because of the uncertainty.

Determinate Progress Bar

These are progress bar that are for task that are somewhat known to us for example can be how long it will take to download a file from the server. These are recommended to use in applications where these tasks are for the users to see along with the progress.

A default Determinate Progress Bar is a linear line which can be set Progress on dynamically and can be hardcoded too (but that wouldn’t make much sense)

Note: While the default types of these are circular and linear it doesn’t mean a Determinate ProgressBar cannot be circular and vice-versa

What exactly are we going to build?

To answer that we can refer to this picture

and also this optionally

this can be called as a circular determinant progress bar with progress on it shown with help of a TextView centered in between

We could also go ahead and create a custom view to do this but for making this tutorial a bit more easier we are going to use another approach.

Prerequisites

1. Android Studio
2. Basic Knowledge of Android Views
3. Kotlin Basic Knowledge

we can use both an activity or a fragment here. So let’s start with the steps right away !

Creating the View

Here we have used an activity to create this view which has a constraint view as its parent

Круглый прогресс бар android studio

A small Android library allowing you to have a smooth and customizable circular ProgressBar like whatsapp and Tez app, it can be use while uploding or downloading file.

I decided to do this because I was really tired to find progressbar like whatsapp and gradient color progressbar and also you can contribute more color style, or new idea to me.

I took reference or take some code from CircleProgress and change it as i need. also add code for set vector image as background and gradient colors.

Add it in your root build.gradle at the end of repositories:

Add the dependency:

You can either simply use the AdCircleProgress widge from this library on a regular ProgressBar .

Simply replace your ProgressBar with AdCircleProgress , and remember to apply corresponding style and attribute for correct behavior.

For example, to create a first AdCircleProgress like whatsapp:

Second AdCircleProgress in which you can change adpgb_finished_stroke_width like below code:

Third AdCircleProgress in which you can change custom:adpgb_inner_drawable means you can change image or vector image in inner circle like below code:

Fourth AdCircleProgress in which you can change custom:adpgb_show_text=»true» means if you want to show progress in percentage like below code:

Fifth AdCircleProgress in which you can add gradient color for progressbar app:adpgb_gradient_color_one=»@color/colorOne» app:adpgb_gradient_color_two=»@color/colorTwo» like below code:

Do not forget to add xmlns:custom custom attr in your root layout :

Android Progress Bar | Circular,Horizontal,Determinate,Indeterminate

We will develop android circular progress bar in this example tutorial.

In an android app, you need to show various types of progress bar to indicate some process.

Horizontal progress bar, circular progress bar, custom progress bar etc. are the types you can use.

Along with these, other types are determinate and indeterminate progress bars.

Use the below links to directly jump to specific type of android progress bar.

Determinate Progress bar

When you know the exact time ratio of the loading process, you should use determinate progress bar.

In the determinate progress bar you need to show to user that how much that process has done it’s operations.

Generally, developers use percentage as an indicator to tell user that how much percentage of the process has done it’s operation.

Indeterminate Progress bar

Indeterminate progress bar means that you do not know how much the process will take.

So this type of progress bar just shows some loading animations without any percentage.

We will develop four types of circular indeterminate progress bars in this example tutorial.

1. Android Circular Progress Bar With Percentage (Determinate)

Today we are going to develop an android custom determinate circular progress bar.

We will also show how many percentages the process has finished. Amount of the percentage is displayed at the center of the circular progress bar.

Progress bar and percentage will increase with the time simultaneously. It does mean that we will create determinate circular progress bar today.

Take a look at the output first, and then we will show how to develop the android circular progress bar.

Creating Android Circular Progress Bar

Follow all the steps below.

Step 1. Create a new project in the Android Studio.

Make a new project in android studio first.

Step 2. Creating drawable resource file

Create one drawable resource file named circular.xml (drawable resource file means in android studio project’s file structure, you will find a folder named drawable inside a res folder as shown in the below image.)

Step 3. Coding circular.xml

Copy and paste following code into circular.xml

Consider the above code to generate circular progress bar. There is a grey colored circle which will be covered by the green circle as per below image.

The code which will generate grey circle (secondary progress) is as below

android:shape = “ring”

Above line set the shape of the progress bar as circle or ring.

android:thicknessRatio=”20.0″

Above line will give thickness to our grey circle. You can change this value to make circle thicker or thinner.

In the tag, center color, end color and startColor has same value so, the whole circle is grey.

You can play around by giving different values to all three variants.

Below code will generate the green circle (primary progress bar)

Properties of tag will define the primary progress.

It will give ring shape and thickness to the progress bar.

tag will give green color in three different options (centerColor, endColor , startColor)

tag will tell compiler to start the green progress bar from 0 value which is initial value. It means that process is starting from the scratch (start from 0%).

Step 4. Updating activity_main.xml

Copy and paste following in activity_main.xml

In above code, we have used a white circular image which you can download here. Put this image in the drawable folder.

TextView is representing how many percentage the process has finished.

Step 5. Describing Handler

We will use Handler and Thread to accomplish our goal.

Above code will create a process for the specific amount of time, which can be decided by you.

You can change the time amount in the below method.

Here 16 is the number you need to increase or decrease as per your requirements.

Step 6. Updating MainActivity.java class

Final code for MainActivity.java

Details Of the Above Code

Look at the below snippets

Above code will declare the objects of Resource, Drawable and ProgressBar classes.

In the above coding lines,

First line will set the progress as 0. It means that green progress bar will start from the 0 percentage.

Second line is setting the secondary progress bar (grey circle) as 100. It means that the whole circle will be created at the starting of the thread.

Third line will set the maximum of percentage. Generally, it is 100 in most of the cases because whenever we deal with percentage as a measuring parameter, the maximum number is always 100.

Fourth line will give layouts from drawable file (circular.xml) to both the progress bars. We have created this file in the Step 3 above.

After initialization process, we are starting the thread.

Thread will start our circular progress from 0 percentage to 100 percentage in around 3 seconds.

That’s all for android circular progress bar. Thank you for visiting and keep sharing resources of demonuts to other learners.

If you have any questions, then feel free to ask in the comment section.

Any suggestion about developing certain type of tutorial are also welcomed.

2. Android Indeterminate Circular Progress Bar (Without Percentage)

We will develop Android Indeterminate Circular Progress Bar in this post.

When you want to tell user that some process is going on and he need to wait till the end of that process, progress bar is the best way to do so.

Progress bar can be of two types regarding the progress status.

YouTube Output

Watch how does all four progress bars looks like

Step 1. Drawable files

For developing custom progress bars, we need to create some drawable xml files to define various properties.

Create a new xml file under res->drawable file and name it “first.xml“

Add below source code in first.xml

Now prepare another xml file named second.xml in the same directory.

Copy the following code in it

Create new xml file in the same directory named “third.xml” and write below lines

Let us understand properties from above three files.

android:shape=”oval”

In the tag, android:shape=”oval” will define the shape of the progress bar.

Value of shape can be ring, rectangle, line or oval.

android:thichness=”20dp”

This property defines the thickness of the circular progress bar.

android:startcolor & android:endcolor

These two properties are from the tag.

First one defines the starting color and second one defines the end color of the gradient effect.

• There is also a third property called centerColor which defines middle color of the gradient effect.

Now make new xml file again in the same directory and name it “fourth.xml”

Enter below code in fourth.xml

In the fourth.xml file. there is reference to the image file.

Download this image by clicking the below link

[sociallocker] Download Red Progress bar Image [/sociallocker]

Above image will rotate constantly.

Image is developed in such way that when it rotates, it creates a shape like circular progress bar.

Step 2. Create All Four Activities

Prepare a new activity named “FirstActivity”.

You will have now two files activity_first.xml and FirstActivity.java

We do need to do anything with FirstActivity.java here.

Just add the following source code in activity_first.xml

We setting the progress bar in the middle of the screen. In the LinearLayout, gravity=”center” is doing this task for us.

In the Progress bar, we have set the drawable as the first.xml file which have created in Step 1.

I have set the indeterminateDuration property as 2000. It is defining the speed of the circular progress bar.

If you want to increase the speed then increase this property. Decrease this property to slow down the progress bar.

Second Activity

Now create another activity called “Second Activity.”

Here you will have activity_second.xml and SecondActivity.java files.

Add below code in activity_second.xml

Third Activity

Create new empty activity named third activity.

Add below code in activity_third.xml

Fourth Activity

Prepare another new activity and name it Fourth Activity.

Write down following code in activity_fourth.xml

Step 3. Towards End

Last thing is to add some code in activity_main.xml and MainActivity.java

Write down below source code in activity_main.xml

Code for MainActivity.java is as follows

I have taken four buttons in this activity.

Each activity will be open on each button click.

3. Horizontal Progress Bar With Percentage In Android (Determinate)

Learn how to create Android Horizontal Progress Bar With Percentage Programmatically.

We will develop horizontal progress bar with percentage in this example tutorial.

There are many processes like downloading, uploading, fetching data from remote server etc. where you need to tell the user to wait for some time.

To accomplish this purpose, showing horizontal progress bar to the user is great option.

If you show the progress bar with percentage then the user will feel more comfortable while waiting.

View Output

This video demonstrate how our example’s output will look a like.

Determinate Horizontal Progress bar

Determinate progress bar means that you tell user that how much process is completed in terms of percentage.

When you know the exact or approximate time amount which will be taken by the process, you should use determinate progress bar.

You should use determinate progress bar when you do not have any idea about timing of the process.

We will create three horizontal progress bar with different designs in this tutorial.

Step 1. Drawable XML files

We need to create drawable xml files to develop various styles for progress bars.

Create a new xml file under res->drawable directory. Name it as progress_limit.xml

Add below source code in it

Prepare another xml file under same directory.

Give name to that file as progress.xml

Write down following code in it

Above two examples will create custom style for our progress bars.

It will create parameters like shape, color, gradient effect etc.

Step 2. Launching Progress bar

Now we need to change activity_main.xml and MainActivity.java files.

Write down the below source code in activity_main.xml file

We are going to show three progress bars. So, I have taken three textviews, three buttons and three progress bars in this file.

All three textviews will show the completion percentage.

I have implemented button for each progress bar. When the user clicks on button, a progress bar related to that button will start it’s operations.

Now consider the below code

Above is our first progress bar.

I have used android’s in-built style for this progress bar. So we do not require to attach any drawable files in the above code.

Below is the code for second horizontal progress bar.

I have attached a drawable xml file progress_limit.xml to this progress bar.

This progress bar contains two types of progresses. Primary progress and Secondary Progress.

Both progresses will increase it’s value simultaneously with the loading of the process.

In this code, I have set the secondary progress as 100 means that it will have full value.

Following is the third progress bar source code.

I have attached progress.xml file from drawable directory which we developed in Step 1.

We will show different colors in the progress bars with help of xml files of drawable directory.

Finally, write down the following coding lines in MainActivity.java

Look at the below code

I have declared three integer variables. These variables will represent the amount or percentage of the completed process.

Following code will run the progress bar.

I have used handler class to start the thread. This thread will approximately take 3 seconds complete.

It means that our progress bar will start from 0 and will reach at 100 percentage in 3 seconds.

You change the time as per your requirements using the following line.

Change the amount to other than 20 in the above code.

In the thread, compiler will check one while() loop.

if the value of the progressStatus variable is less than 100 then compiler will execute the code inside the while() loop, otherwise, it will terminate the thread.

When progressStatus is less than 100 then the compiler will increase the value of progressStatus by one unit.

After that, it will update the value of textview with latest value of progressStatus using below line.

Above code will also set the progressStatus to the progress bar.

4. Android Indeterminate Horizontal Progress Bar (Without Percentage)

We will Programmatically create Android Indeterminate Horizontal Progress Bar example tutorial today.

Generally, we use progress bar when we want to tell user that some process going on.

Here, user have to wait until the process is completed. The best way to handle this situation is to animate some progress symbol.

Now process also can be of two types. One which have specific time amount to complete it’s operation which is called determinate.

Other one is indeterminate where you do not have any clue about the total time required by the process.

In determinate process, you can show percentage to give user a little idea about how long he needs to wait.

While in the case of indeterminate you can not show any indicator like percentage.

So you need to create a specific indeterminate progress bar for scenario.

We will create horizontal indeterminate progress bar in this example.

This example includes four different types of indeterminate progress bars.

All Four Horizontal Progress Bars

Below is the visual representation of all four progress bars.

Follow all the below steps to complete this tutorial.

Step 1. Main Layout

First of all, create a new activity in the android studio. It is advisable to select “Empty Activity” while creating fresh project in the android studio.

We will define our xml code for progress bars in the activity_main.xml file.

Add the below code snippet in the activity_main.xml file.

First three progress bars have android’s in built style for horizontal progress bar.

Below is the style for first progress bar.

Below two styles are for second and third progress bars respectively.

Now consider the below coding lines for fourth progress bar.

Here, we will use custom drawable along with the in-built style.

Drawable file will give specific properties to make custom horizontal progress bar.

We have used second.xml drawable file in the fourth progress bar.

Let us create second.xml file.

Create a new drawable xml file under directory res->drawable. Name it as second.xml

Copy the following code in it.

Step 2. Main Code

After working on XML files, it is time to play with java file.

Copy the following code snippet in MainActivity.java file.

Because we are using just android’s in-built style in the first three progress bars, we do not need to add any coding lines in java file for these progress bars.

We have handled some scenarios for the fourth one.

Consider the below code

First line is declaring the object of the ProgressBar class.

Second one is creating the integer variable “pStatus” with zero as the initial value.

Third line is giving us Handler’s object.

Let us understand the below code structure for fourth progress bar.

First, we will initialize handler object to avoid null pointer exception

Then we will create a new thread to start the horizontal progress bar.
Compiler will check for while() method in the run() method of the thread.

In while() loop, compiler will check if the value of the integer variable pStatus is less than 100 or not.

If pstatus has less value than 100 then compiler will enter in the while loop. After entering, it will increase the value of pStatus by one.

Now it will again check one if condition. If the value of pStatus is 99 than it will set the value of pStatus as zero.

This if condition is responsible for the infinite running of the thread hence the infinite running of the horizontal progress bar.

After this, compiler will set the value of the primary progress and the secondary progress.
