BaseActivity for Navigation

Question

I\'m building a base activity for navigation and want something flexible so the Activity dictates to the Base Activity which layout to inflate.

I have the following<

You can refer to my following code, pay attention to addContentView in my base activity (here I name it NavigationDrawerActivity)

Base activity:

public class NavigationDrawerActivity extends AppCompatActivity {
    private DrawerLayout mDrawerLayout;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_navigation_drawer);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, mDrawerLayout, toolbar, R.string.drawer_open, R.string.drawer_close);
        mDrawerLayout.setDrawerListener(toggle);
        toggle.syncState();
    }
    /**
     * called in extending activities instead of setContentView...
     *
     * @param layoutId The content Layout Id of extending activities
     */
    public void addContentView(int layoutId) {
        LayoutInflater inflater = (LayoutInflater) this
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View contentView = inflater.inflate(layoutId, null, false);
        mDrawerLayout.addView(contentView, 0);
    } 
}

Then in other activities, for example, MainActivity:

public class MainActivity extends NavigationDrawerActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        super.addContentView(R.layout.activity_main);
    }
}

Hope this helps!
