How can an activity use a Toolbar without extending AppCompatActivity

Question

I have an activity HomeView which already extends another activity and it cannot extend AppCompatActivity. But HomeView needs to have a Toolbar. Th

Actually, it is pretty simple:

public class YourActivity extends SomeActivity implements AppCompatCallback {

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

    // create the delegate
    delegate = AppCompatDelegate.create(this, this);
    delegate.onCreate(savedInstanceState);
    delegate.setContentView(R.layout.activity_details);

    // add the Toolbar
    Toolbar toolbar= (Toolbar) findViewById(R.id.toolbar);
    delegate.setSupportActionBar(toolbar);
  }

  @Override
  public void onSupportActionModeStarted(ActionMode mode) {
    // leave it empty
  }

  @Override
  public void onSupportActionModeFinished(ActionMode mode) {
    // leave it empty
  }

  @Nullable
  @Override
  public ActionMode onWindowStartingSupportActionMode(ActionMode.Callback callback) {
    return null;
  }

That's it. Please, don't forget to set a AppTheme.NoActionBar theme to YourActivity in the AndroidManifest.xml.
