Disable navigation drawer on startup

I want my navigation drawer to be disabled when loading the app, and if the user has completed some specific tasks, it will be enabled.

In short, there is a way to disable the toggle navigation button and re-enable it based on user action.

Edit: I updated my activity as follows:

public class MainActivity extends Activity
    implements NavigationDrawerFragment.NavigationDrawerCallbacks {

    private NavigationDrawerFragment mNavigationDrawerFragment;

    private CharSequence mTitle;

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

        mNavigationDrawerFragment = (NavigationDrawerFragment)
                getFragmentManager().findFragmentById(R.id.navigation_drawer);
        mTitle = getTitle();

        // Set up the drawer.
        DrawerLayout navigationDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mNavigationDrawerFragment.setUp(
                R.id.navigation_drawer,
                navigationDrawerLayout);

        navigationDrawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
    }
}

    @Override
    public boolean onOptionsItemSelected(android.view.MenuItem item) {
        if (item.getItemId() == android.R.id.home) {

        }
        return super.onOptionsItemSelected(item);
    }
    ...
}

      

        
        
        
      

    

but when the app starts, I can open the navigation drawer which I don't want
