Custom TabLayout Indicator in — Android.

Make your Indicator with your choice.

Mar 2, 2020 · 4 min read

This article belongs to what I have learned today, so basically I need to Implement a custom TabLayout Indicator, with rounded corners and with some extra spacing like the below example.

Basic TabLayout Indicator Color:

If we need to set the Indicator color, without any custom Indicator, so in that case, we only need to set the app:tabIndicatorColor as you can from the below XML file:

From the above XML, you will see the normal TabLayout Indicator color, without any custom view.

Result:

More Attributes:

You can also play with other attributes of TabLayout some of them are listed below.

Custom TabLayout Indicator Implementation:

Now, le t ’s start with the custom TabLayout Indicator Implementation, Let’s break into steps:

Step1

Make a drawable of layer-list, with the name tab_indicator , Like below code snippet.

In the above code, I added a rectangle shape tag, with a corner radius of 5dp ànd with a solid color.

Step2

We need to add a drawable to our TabLayout, Like below code snippet.

Now what we achieved is half of our requirements, currently showing a custom TabLayout Indicator, but now we need some spacing from the bottom and as well as from left, right Indicator.

Step3

For bottom padding, we need to add android:paddingBottom to TabLayout, Like the below code snippet, and we will see the result.

Step4

For Left/Right Indicator Margins, we need to add margin in our drawable file tag, which we created earlier.

In the above code, what I did is to add an end and `margin to the tag, and we will see the result.

Finally, we achieved our goal, everything is perfectly fine, what I noticed is it’s working fine on all versions of Android except Android 9.0 which is Pie. Let me show you how it look on Android 9.0

The issue was it’s not picked up the color which I defined in my drawable, now let’s directly move towards the solution.

Solution:

The Solution for the above issue is to define the app:tabIndicatorColor the color which I defined on my drawable, the same color I defined in the app:tabIndicatorColor

That’s it after defining the app:tabIndicatorColor it’s working fine in all the android versions.

Conclusion

This article described to you how you can create a custom TabLayout Indicator, also described to you how you can be fixed the Android 9.0 color issue.

I hope this article is helpful. If you think something is missing, have questions, or would like to give feedback, go ahead and leave a comment below. I’d appreciate the feedback.

Android Tablayout Tutorial | Custom Fragments,ViewPager,Swipe

Whatsapp is using Android tablayout for basic navigation.

In today’s Android tablayout example, we will develop that kind of structure programmatically.

1. Android Tablayout Example With Fragments,ViewPager

Android tablayout uses fragments, material design and view pager as basic components.

First, watch the output, then we will prepare it.

Step 1: Create a new project in Android Studio.

Always try to create new project in android studio with empty activity.

Step 2: Update build.gradle(Module:app) file

Add below in build.gradle(Module:app) file

Whole source code for build.gradle(Module:app)

Step 3: Updating colors.xml

Go to the res->values->colors.xml directory

update colors.xml as below

Step 4: Preparing three fragments

Create three fragments and give them name as “OneFragment,” “TwoFragment,” and “ThreeFragment.“

In every application with tab layout, use of fragment is must. Gmail is also using same concept.

Fragments simplifies the back stack problem arises if we use activity instead of fragment.

Here, we are using three fragments. You can increase or decrease this number as per your requirements.

Add below code in fragment_one.xml

Add following in OneFragment.java

Copy below source code in fragment_two.xml

Copy following code in TwoFragment.java

Add below code in fragment_three.xml

Paste below code in ThreeFragment.java

Step 5: Updating MainActivity

update activity_main.xml as below

Update MainActivity.java as per following

Step 6: Explanation of MainActivity.java

First of all setupViewPager() method is called.

Consider below source code

In above method, we have added each fragment to view pager adapter.

addFragment() method have two parameters. First have the object of fragments and second have the name of that fragment.

The value of Second parameter will shown as the name of the tab.

After that, ViewPagerAdapter class is defined. You do not need to do any modification in this class.

4. Android Change Tab Icon/Text/Background Color/Text Color When Selected

Android change tab icon when selected tutorial with example is tonight’s hot topic.

In this tutorial, you will learn how to change tab icon, tab text, tab icon color, tab text color, tab background color, indicator color programmatically when user selects the tab.

Developers use these features to indicate the current working tab to the user.

Output

What will be the final output at the end of this example?

Check it out in the below video.

Step 1. Update colors.xml file

Add some necessary colors in the colors.xml file which is located at the values->colors.xml path.

Step 2. Necessary strings

A file which is available at values->strings.xml needed to be replaced with following source code

Step 3. Various Icons

As we want to change the color or may be the whole icon when the user clicks on the tab, we need to add different icons for every situation.

There should be different icons for both events, when the tab is selected and when it is deselected.

Click on below link to download necessary icons for this practical example tutorial.

Now copy all these icons in the mipmap folder.

Step 4. Making Drawable resource files

In the drawable folder, make one new resource file and name it like roundback.xml

Copy the following code in it

Create another resource file named roundleft.xml and add the below code

Step 5. Four Fragments for Four Tabs

There are four tabs in this android studio example so we have to create separate fragments for each tab.

Make first fragment with name IntroFragment.

Add below code in IntroFragment.java file

Code for fragment_intro.xml

Now second fragment’s name is Location.

LocationFragment.java

fragment_location.xml

Third fragment is Login Fragment

LoginFragment.java

fragment_login.xml

Product Fragment is the last one.

ProductFragment.java

fragment_product.xml

Step 6. Main Activity

In the last step, you need to add required code in Main Activity’s both files.

In the activity_main.xml, add following code

I have designed four Linear Layouts, which represents the four tabs.

Each Linear layout includes one imageview and one textview.

ImageView represnts the tab icon and Textview represents the tab text.

You can add other UI elements as per your requirement.

After four linear layouts, there is a frame layout in which fragment for each tab will be loaded.

Update Main Activity java file

Finally, time to update MainActivity.java file

Step 7. Explanation of Main Activity

In the main activity, I have defined four linear layouts which are representing four tabs as per below.

Now, I have set onclick listeners for each above linear layout.

It will work when the user clicks on any tab.

Now you might have noticed that two methods are present in each click listener.

Both these methods are described below.

unselectElse

This method will deselect the current selected tab.

For example, user first clicks on Login fragment, so the icon color and text color for login tab is changes to white.

Now user selects or clicks on the product fragment, so the icon and text color for product is changed to white but here, login tab is also white.

If we do not change icon and text color of login tab back to black, there will be two selected tabs which is not ideal condition.

so unselectElse method will make the look and feel of selected tab back to the deselected.

Code for this method

removeAllFragment()

This method will simply empty the fragment backstack.

Whenever new fragment is loaded in the frame layout, it is added into the backstack also.

This method will be helpful to overcome this issue.

The second parameter of this method will decide whether to add newly loaded fragment into the backstack or not.

Checkout it’s implementation

That was all the details about android change tab icon when selected.
