Check this link Android new Bottom Navigation bar

public class MainActivity extends AppCompatActivity { 
    private BottomBar mBottomBar; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     // Notice how you don't use the setContentView method here! Just 
     // pass your layout to bottom bar, it will be taken care of. 
     // Everything will be just like you're used to. 
     mBottomBar = BottomBar.bind(this, R.layout.activity_main, 
       savedInstanceState); 

     mBottomBar.setItems(
       new BottomBarTab(R.drawable.ic_recents, "Recents"), 
       new BottomBarTab(R.drawable.ic_favorites, "Favorites"), 
       new BottomBarTab(R.drawable.ic_nearby, "Nearby"), 
       new BottomBarTab(R.drawable.ic_friends, "Friends") 
     ); 

     mBottomBar.setOnItemSelectedListener(new OnTabSelectedListener() { 
      @Override 
      public void onItemSelected(final int position) { 
       // the user selected a new tab 
      } 
     }); 
    } 

    @Override 
    protected void onSaveInstanceState(Bundle outState) { 
     super.onSaveInstanceState(outState); 
     mBottomBar.onSaveInstanceState(outState); 
    } 
}
