Create text selector:

<?xml version="1.0" encoding="utf-8"?>
<selectorxmlns:android="http://schemas.android.com/apk/res/android">
<itemandroid:color="@color/black"android:state_pressed="true" /> <!-- pressed -->

</selector>

Create drawable selector for each button icon:

<?xml version="1.0" encoding="utf-8"?>
<selectorxmlns:android="http://schemas.android.com/apk/res/android">
<itemandroid:drawable="@drawable/ic_button1_dark"android:state_pressed="true" /> <!-- pressed -->
<itemandroid:drawable="@drawable/ic_button1_dark"android:state_selected="true" /> <!-- selected -->
<itemandroid:drawable="@drawable/ic_button1" /> <!-- default -->

Create menu resource file with items. Where title is title of button and icon is button drawable.

<?xml version="1.0" encoding="utf-8"?>
<menuxmlns:android="http://schemas.android.com/apk/res/android">
<itemandroid:id="@+id/menu_button1"android:icon="@drawable/tab_button1_selector"android:title="Button1" />
<itemandroid:id="@+id/menu_button2"android:icon="@drawable/tab_button1_selector"android:title="Button2" />
<itemandroid:id="@+id/menu_button3"android:icon="@drawable/tab_button1_selector"android:title="Button3" />
<itemandroid:id="@+id/menu_button4"android:icon="@drawable/tab_button1_selector"android:title="Button4" />
<itemandroid:id="@+id/menu_button5"android:icon="@drawable/tab_button1_selector"android:title="Button5" />
</menu>

Create style for button

<stylename="TabButtonTextStyle"parent="android:Widget.Button">
<itemname="android:textSize">12sp</item>
<itemname="android:textColor">@drawable/tab_button_text_selector</item>
</style>

Add bottomtablayout view to activity layout:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context="com.stfalcon.bottomtablayout_sample.MainActivity">
<FrameLayoutandroid:id="@+id/container"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_above="@+id/bottomTabLayout" />
<com.stfalcon.bottomtablayout.BottomTabLayout
android:id="@+id/bottomTabLayout"android:layout_width="match_parent"android:layout_height="58dp"android:layout_alignParentBottom="true"android:background="@color/dark" />
</RelativeLayout>

In activity class:

@OverrideprotectedvoidonCreate(BundlesavedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
container = R.id.container; //Container for fragments//Setup button tab layoutbottomTabLayout = (BottomTabLayout) findViewById(R.id.bottomTabLayout);
//set button text stylebottomTabLayout.setButtonTextStyle(R.style.TextGray16);
// set buttons from menu resourcebottomTabLayout.setItems(R.menu.menu_bottom_layout);
//set on selected tab listener.bottomTabLayout.setListener(newBottomTabLayout.OnItemSelectedListener() {
@OverridepublicvoidonItemSelected(intid) {
switchFragment(id);
}
});
//set button that will be select on start activitybottomTabLayout.setSelectedTab(R.id.menu_button1);
//enable indicatorbottomTabLayout.setIndicatorVisible(true);
//indicator heightbottomTabLayout.setIndicatorHeight(getResources().getDimension(R.dimen.indicator_height));
//indicator colorbottomTabLayout.setIndicatorColor(R.color.green);
//indicator line colorbottomTabLayout.setIndicatorLineColor(R.color.dark);
}

For example we can switch fragments in container:

/** * Show fragment in container * @param id Menu item res id */publicvoidswitchFragment(intid) {
Fragmentfragment = null;
switch (id) {
caseR.id.menu_button1:
fragment = ColoredFragment.newInstance(R.color.blue, "Fragment 1");
break;
caseR.id.menu_button2:
fragment = ColoredFragment.newInstance(R.color.green, "Fragment 2");
break;
caseR.id.menu_button3:
fragment = ColoredFragment.newInstance(R.color.pink, "Fragment 3");
break;
caseR.id.menu_button4:
fragment = ColoredFragment.newInstance(R.color.blueDark, "Fragment 4");
break;
caseR.id.menu_button5:
fragment = ColoredFragment.newInstance(R.color.white, "Fragment 5");
break;
}
if (fragment != null) {
FragmentTransactiontransaction = getSupportFragmentManager().beginTransaction();
transaction.replace(container, fragment);
transaction.commit();
}
}

For showing bubble count on tab.

bottomTabLayout.showTabBubbleCount(R.id.menu_button1, 3);

You can style bubble with methods:

bottomTabLayout.setTabBubbleColor(ContextCompat.getColor(this, R.color.blue));
bottomTabLayout.setTabBubblePadding(0, 0, 0, 0);
bottomTabLayout.setTabBubbleTextStyle(R.style.TextWhite12);
