我有一个已经设计了隐藏在所有的意图标题栏的应用程序。我想从一个按钮利用Activity.openOptionsMenu（）。它适用于2.2罚款，但是当我运行蜂窝应用程序，调用openOptionsMenu（）似乎不工作。有另一种方式？

的onclick code在这里，如果它很重要。这是我的MapView活动里面，延长图形页面：

  OnClickListener OCL =新OnClickListener（）  {     @覆盖     公共无效的onClick（视图v）     {        开关（v.getId（））        {           案例R.id.b_options：                                  Log.d（TAG选项点击）;                                  mymapview.this.openOptionsMenu（）;           打破;           案例R.id.b_ preV：                                  Log.d（TAG，preV点击）;           打破;        }     }  }; 

解决方案

你有你的应用程序的动作条？我相信openOptionsMenu（）只适用于在蜂窝伴随动作条。 ICS不带回菜单按钮，但你不再需要openOptionsMenu）的动作条（工作。

I have an app that's been designed with the titlebar hidden in all intents. I want to utilize Activity.openOptionsMenu() from a button. It works fine on 2.2 but when I run the app on honeycomb, calling openOptionsMenu() doesn't seem to work. Is there another way?

onclick code here, if it matters. This is inside my mapview activity, extending MapView:

  OnClickListener ocl =  new OnClickListener()
  {

     @Override
     public void onClick (View v)
     {
        switch (v.getId ())
        {
           case R.id.b_options:
                                  Log.d (TAG, "options clicked");
                                  mymapview.this.openOptionsMenu ();
           break;

           case R.id.b_prev:
                                  Log.d (TAG, "prev clicked");
           break;
        }

     }
  };

Do you have an ActionBar in your application? I believe openOptionsMenu() only works with an accompanying ActionBar in Honeycomb. ICS doesn't bring back the menu button, but you no longer need an ActionBar for openOptionsMenu() to work.
