How to make Custom Switch in Android?

Hello World, Today we are going to make a custom switch. Why? Because the default one looks so boring and ugly. Why we use a switch? As the name suggests, the switch is used to trigger the value either it is on, or it is off. Let’s see, how our custom switch will look at the end of the tutorial.

In the above gif, there are 3 switches. The First one is the default one and the second and third are our custom switches. To make these custom switches we need to follow certain steps are as follows:

Step 1. Add Switch to Activity Layout

First. we need to add the switch to our layout XML file. We will add SwitchCompat to the layout.

Look at the below code for better understanding.

In the above code, things to be noticed are app:track and android:thumb attributes.

The track is the horizontal container where our thumb or round shape view is placed and the thumb is, as I told you before, is the round shape where we will add an image on top of it.

Step 2. Make Custom Track for Switch

To make our custom track we need to make a drawable file and set the root element as a selector. So click on the drawable folder and make a new file and name it as track.

In our track.xml we write this code for making the custom track.

In the above code, we made two items in the selector where the first item represents the state when the switch is off or not checked and the second item represents the state when the switch is on or checked.

In the first item, we made a shape of a rectangle and fill white color with having corner radius with a grey color stroke or outline and in the second item the only difference is filled color will be our accent color and stroke will be removed but the corner radius will be the same.

Now let’s make our thumb part where we will add images on the thumb.

Step 3. Make Custom Thumb with Image.

To make custom thumb for the switch, create a drawable file in a drawable folder and name it as the thumb.

In our thumb.xml file, we will write the below code.

as track.xml here we also have the root element as a selector and have the same item tags but this time we set drawable in the attribute. These drawable are our drawable file where we will add images. Let’s add our vector icons to use in thumb drawable.

Add images for thumb

Right-click on drawable then click on new then select vector assets and then choose your icon from clip art. for demo purpose we are selecting notification on and off icon.

After adding the icons, we need to make drawable files for custom thumb off and one for the thumb on which will be add in thumb.xml as drawable.

Let’s make the first file in the drawable for thumb off and set an image to the thumb. Check the below code.

If you noticed, we are using the layer-list as the root element and in the child, we have 2 items.

The first item is our oval (round) shape of the thumb with the size and background color and the second item is our image drawable with 12dp padding from the top, bottom, left, and right.

So this was for when the switch is off our custom thumb will look like this now its turn for thumb true when the switch is on.

Create a new file with the name switch_thumb_true and the code will be like below.

Like thumb false, this code is similar to it but the differences are we added the stroke to the round shape and of course change the image drawable.

Now we have made the all necessary files now its time to run our app and your custom switch is ready. Tada.

This switch is our middle one if you want to make track height small then you need to do some extra work. Keep reading.

This post shows how to use android switch button, apply material styles, create custom styles, create custom switch button and how to handle switch button click events.

Android Switch XML Element

Android Switch Properties

Some of the important switch properties are textAppearance, textColor, track, thumb, switchTextAppearance, textOn, testOff, background, and showText.

Property thumb is used to set a drawable that switches back and forth, property track is used for setting a drawable as track for switch thumb, textOn and textOff are used to set text to be displayed when switch is in on or off state, textswitchTextAppearance is used to set style for switch text, and showText is used to indicate whether to show switch text or not.

Android Switch Material Style

Android system provides many material themes. When application level theme is set to one of the material themes, android switch will be displayed applying default switch material theme of the application theme used in the application. Below screen shot shows switch button in both on and off states when application theme is set to Theme.AppCompat.

Android Switch Button Custom Style Application Level

Application level themes can be customized by setting properties to custom values. If you customize properties related to UI controls, the changes will be applied to all UI controls and throughout the application. To change switch text color and switch button color, you need to set textColorPrimaryDisableOnly and colorAccent properties to custom values.

Below theme is an example of custom application theme added to res/values/styles.xml file. You can apply it to an application by setting theme attribute of application element in mainifest xml file.

Below screen shot shows switch button after application theme is set to custom material theme defined above.

Android Switch Custom Style Individual

If you want to change switch style only in a particular section of your application, then define custom switch widget style by inheriting Widget.AppCompat.CompoundButton.Switch as shown below and apply it to switch elements using theme attribute.

Switch attribute colorControlActivated can be used to set track and thumb color when switch is active and colorForeground can be used to set track color when switch is in normal state.

You can use thumbTint and trackTint properties to change color of thumb and track. Applying colors to track and thumb using selector xml allows you to apply different colors for different states, see custom switch section.

Android Switch Event Listener

Switch on and off events or switch drag event can be handled in two ways. One way of handling switch click event is by defining a method in your activity or fragment with View as input parameter and setting it as value for onClick attribute of Switch in layout xml as shown below.

Second way of handling switch on/off event is by defining OnCheckedChangeListener and adding it to switch button by using setOnCheckedChangeListener method.

Custom Switch Button

Android switch with custom track

You can customize android switch track by defining a drawable xml resource as shown below. You need to save it in res/drawable folder, our example file name switch_track_custom.xml, and apply it to switch by using track attribute.

Below xml, used as switch_color in the above drawable, is color selector for track. Color is applied based on the state of switch. This file needs to be saved in res/color folder.

Below xml shows applying the custom track drawable to Switch.

Output of custom track of switch.

Android switch with custom thumb

Android switch thumb can be customized by using material icon and defining drawable xml resource.

To do that, first download one of the android material icons which you want to use in your application or use any other image you may have and save it in res/drawable folder.

Then define drawable xml resource as shown below in res/drawable folder, our example file name is switch_thumb_custom.xml. This xml uses the above downloaded icon, defines shape and sets colors. To apply this to a switch, set its thumb attribute to the drawable xml.

In the above xml switchTrackNormal and switchThumbBgActive are colors defined in res/values/colors.xml

Below color selector xml saved as switch_color.xml is used in the custom thumb drawable xml defined above.

Below switch element in layout xml uses above custom switch thumb and switch track.

With switch button track customization explained from above section and switch button thumb customization explained in this section, the custom switch button will appear as shown below in normal and active states.

Switch

Switch — ещё один вид переключателей, который появился в Android 4.0 (API 14). Находится в разделах Commons и Buttons. Фактически, это замена немного устаревшего ToggleButton. В новых проектах лучше использовать Switch.

Компонент используется в том случае, когда нужно переключиться на противоположное состояние — да/нет, вкл./выкл., открыть/закрыть. В реальной жизни это выглядит следующим образом.

При добавлении компонента в макет студия рекомендует использовать использовать SwitchCompat или SwitchMaterial. Общий принцип работы у них одинаковый, отличия касаются дизайна.

Компонент представляет собой полоску с двумя состояниями и сопровождающим текстом. Переключиться можно сдвиганием ползунка или касанием экрана в области компонента (не только на самом ползунке, но и на сопровождающем тексте).

По умолчанию компонент находится в выключенном состоянии. Чтобы установить его в включённом состоянии на этапе разработки, используйте атрибут android:checked=»true».

Сопровождающий текст задаётся в атрибуте android:text. А текст на самом переключателе задаётся при помощи атрибутов android:textOn (методы getTextOn() и setTextOn()) и android:textOff (методы getTextOff() и setTextOff()). Обратите внимание, что сопровождающий текст может быть очень большим и положение самого переключателя относительно этого текста можно регулировать при помощи атрибута android:gravity (смотри пример ниже). Если сопровождающий текст вам не нужен, то не используйте атрибут android:text.

Момент переключения можно отслеживать при помощи слушателя CompoundButton.OnCheckedChangeListener.

SwitchCompat

Студия рекомендует использовать SwitchCompat. Явных отличий у него нет.

Для показа текста на кнопке переключателя установите в true значение атрибута app:showText.

Не забывайте, что данный компонент можно использовать только в активностях типа AppCompatActivity.

Вы можете задать свой стиль для SwitchCompat, добавив строки в styles.xml

Цвет дорожки, вдоль которой двигается ползунок, можно поменять также через стиль:
