Installation

allprojects {
 repositories {
   ...
   maven { url 'https://jitpack.io' }
  }
}

dependencies {
  compile 'com.github.rahimlis:badgedtablayout:v1.0'
}

Usage

Add BadgedTabLayout as if you added TabLayout itself

<android.support.design.widget.AppBarLayout ...>
  
  <android.support.v7.widget.Toolbar ... />
    
  <com.rahimlis.badgedtablayout.BadgedTabLayout
       android:id="@+id/tabs"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       app:badgeBackgroundColor="@color/badge_background_color"
       />

  </android.support.design.widget.AppBarLayout>

then in java do:

BadgedTabLayout tabLayout = (BadgedTabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(mViewPager);

to set text of the badge use:

  //first parameter is the tab index, at which badge should appear
  tabLayout.setBadgeText(1,"1");
  //if you want to hide a badge pass null as a second parameter
  tablayout.setBadgeText(0,null);

Note: by default badges are hidden. You need to set some text to show it up.

Customization

you can customize tab text colors as if you would do it for tabLayout

app:tabTextColor="@color/your_unselected_text_color"
app:tabSelectedTextColor="@color/your_selected_text_color"

additionally you can change badge background color, as well as badge text color and text size

app:tabTextColor="@color/your_unselected_text_color"
app:tabSelectedTextColor="@color/your_selected_text_color"
app:badgeTextColor="@color/your_selected_color"
app:badgeSelectedTextColor="@color/your_selected_color"
app:badgeBackgroundColor="@color/your_selected_color"
app:badgeSelectedBackgroundColor="@color/your_selected_color"
app:badgeTextSize="11sp"

another way to do this is to create color state list and pass it to corresponding field:

<!-- file badge_background_color.xml / badge_text_color.xml at color directory -->
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="#ff0" android:state_selected="true" />
    <item android:color="#f0f" android:state_selected="false" />
</selector>

then:

app:badgeBackgroundColor="@color/badge_background_color"
app:badgeTextColor="@color/badge_text_color"

you also can change every property programmatically, look at class documentation for more information.
