import android.support.design.widget.BottomNavigationView;
import android.support.v7.app.AppCompatActivity;
import android.view.MenuItem;

public class MainActivity extends AppCompatActivity {

    private BottomNavigationView bottomNavigationView;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        bottomNavigationView = (BottomNavigationView)
                findViewById(R.id.bottom_navigation);

                new BottomNavigationView.OnNavigationItemSelectedListener() {
                    @Override
                    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                        switch (item.getItemId()) {

                            case R.id.action_hotnews:

                                break;
                            case R.id.action_movies:
                                Utils.showToast(MainActivity.this, "Movies");
                                break;
                            case R.id.action_music:
                                Utils.showToast(MainActivity.this, "Music");
                                break;
                            case R.id.action_games:
                                Utils.showToast(MainActivity.this, "Games");
                                break;
                            case R.id.action_more:
                                Utils.showToast(MainActivity.this, "More");
                                break;

                        }
                        return false;
