Answer 1

1.create a android project

2.

Create a menu/drawer_view.xml file:

android:id="@+id/cinemas"
android:icon="@drawable/ic_one"
android:title="Cinemas" />

3.

Now, let's setup the drawer in our activity. We can also setup the menu icon too.

public class MainActivity extends AppCompatActivity {
private DrawerLayout mDrawer;
private Toolbar toolbar;
private NavigationView nvDrawer;

private ActionBarDrawerToggle drawerToggle;

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

toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
  
getSupportActionBar().setDisplayHomeAsUpEnabled(true);

mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
mDrawer.openDrawer(GravityCompat.START);
return true;
}

return super.onOptionsItemSelected(item);
}
}

3.

Navigating between Menu Items
Setup a handler to respond to click events on the navigation elements and swap out the fragment. This can be put into the activity directly:

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
nvDrawer = (NavigationView) findViewById(R.id.nvView);
setupDrawerContent(nvDrawer);
}

private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(
new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
selectDrawerItem(menuItem);
return true;
}
});
}

public void selectDrawerItem(MenuItem menuItem) {
Fragment fragment = null;
Class fragmentClass;
switch(menuItem.getItemId()) {
case R.id.cinemas:
fragmentClass = FirstFragment.class;
break;
}

try {
fragment = (Fragment) fragmentClass.newInstance();
} catch (Exception e) {
e.printStackTrace();
}

FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.flContent, fragment).commit();

menuItem.setChecked(true);
setTitle(menuItem.getTitle());
mDrawer.closeDrawers();
}

}

public class ColorsFragment extends Fragment {

public ColorsFragment() {}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

View rootView = inflater.inflate(R.layout.fragment_colors, container, false);
RecyclerView recyclerView = (RecyclerView) rootView.findViewById(R.id.list);

recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

ItemData itemsData[] = {
new ItemData("Taj cinima", R.drawable.circle),
new ItemData("Grand cinima", R.drawable.color_ic_launcher),
new ItemData("prime cinima", R.drawable.indigo),
};

MyAdapter mAdapter = new MyAdapter(itemsData);
recyclerView.setAdapter(mAdapter);

recyclerView.setItemAnimator(new DefaultItemAnimator());

return rootView;
}
}
