ListView - ArrayAdapter - onItemClick

Question

所以我使用slidingmenu来创建一个漂亮的小菜单，但没有片段。有了这个，我设置了一个ListView来显示我的菜单。试图使用onItemClick，然后我可以切换到下一个活动，但我得到一个致命的例外，当我运行应用程序。下面是我的代码：

private void mainMenu() { 
    menu = new SlidingMenu(this); 
    menu.setMode(SlidingMenu.LEFT); 
    menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN); 
    menu.setShadowWidth(5); 
    menu.setFadeDegree(0.35f); 
    menu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT); 
    menu.setBehindWidth(R.dimen.shadow_width); 
    menu.setShadowDrawable(R.drawable.shadow); 
    menu.setBehindOffsetRes(R.dimen.slidingmenu_offset); 
    menu.setMenu(R.layout.menu_frame); 

    ListView v = (ListView)findViewById(R.id.menu_frame); 
    v.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, menu_items)); 
    v.setOnItemClickListener(new OnItemClickListener(){ 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) { 
      Log.i(TAG, "HERE"); 
     } 

    }); 
} 

的logcat：

我恢复到上次工作版本，然后重新添加的一切，似乎工作。感谢和遗憾浪费时间。
