Membuat Navigation Drawer

 

MainActivity.java

public class MainActivity extends AppCompatActivity {

    private AppBarConfiguration mAppBarConfiguration;

        NavigationView navigationView = findViewById(R.id.nav_view);
        // Passing each menu ID as a set of Ids because each
        // menu should be considered as top level destinations.
        mAppBarConfiguration = new AppBarConfiguration.Builder(
                R.id.nav_home, R.id.nav_gallery)
                .setOpenableLayout(drawer)
                .build();

        navigationView.getMenu().findItem(R.id.nav_second_activity).setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                drawer.close();

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
