Step01:First Import compile'com.android.support:design:26.1.0' And Rebuild The App

Step02: Make Some Menu Item accroding to menu.xml

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"> <item android:title="Send" android:id="@+id/sendID" app:showAsAction="ifRoom" android:icon="@drawable/ic_send_black_24dp" /> <item android:title="Share" android:id="@+id/shareID" app:showAsAction="ifRoom" android:icon="@drawable/ic_share_black_24dp" /> <item android:title="Contact" android:id="@+id/contactID" app:showAsAction="ifRoom" android:icon="@drawable/ic_contacts_black_24dp" />

<?xml version="1.0" encoding="utf-8"?> <relativelayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.rhtechbd.mybottomnevigationdemo.MainActivity"> <android.support.design.widget.BottomNavigationView android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:id="@+id/bottomBarID" android:background="#f2e570" app:itemTextColor="#121010" app:menu="@menu/menu" > </android.support.design.widget.BottomNavigationView> </RelativeLayout>

Step 04: Write Some Java codes.. also setOnNavigationItemSelectedListener according to MainActivity.JAVA

public class MainActivity extends AppCompatActivity { private BottomNavigationView bottomBar; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); bottomBar= (BottomNavigationView) findViewById(R.id.bottomBarID); bottomBar.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() { @Override public boolean onNavigationItemSelected(@NonNull MenuItem item) { if(item.getItemId()==R.id.sendID) { Toast.makeText(getApplicationContext(),"Send is clicked", Toast.LENGTH_LONG).show(); } if(item.getItemId()==R.id.shareID) { Toast.makeText(getApplicationContext(),"Share is clicked", Toast.LENGTH_LONG).show(); } if(item.getItemId()==R.id.contactID) { Toast.makeText(getApplicationContext(),"Contact is clicked", Toast.LENGTH_LONG).show(); } return true; } }); }
