Answer 1

那是因为你的菜单中关闭期间发动onNavigationItemSelected您的活动。我建议你在菜单关闭后启动你的活动。

private static final int NAVDRAWER_ANIM_DURATION = 250; 
public void goToActivity(Class<?> mClass){ 

    closeNavigationView(); // in this method you can close your drawer 
    Intent intent = new Intent(this, mClass); 
    new Handler().postDelayed(new ActivityTransitionRunnable(intent), NAVDRAWER_ANIM_DURATION); 

}//goToActivity 

private class ActivityTransitionRunnable implements Runnable { 
    Intent mIntent; 
    private ActivityTransitionRunnable(Intent intent) { 
     mIntent = intent; 
    } 
    public void run() { 
     startActivity(mIntent); 
    } 
}//ActivityTransitionRunnable
