導航抽屜問題

Question

我正在關注Android開發人員http://developer.android.com/training/implementing-navigation/nav-drawer.html的示例。

當我到達：

 mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, 
      R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close) { 

     /** Called when a drawer has settled in a completely closed state. */ 
     public void onDrawerClosed(View view) { 
      super.onDrawerClosed(view); 
      getActionBar().setTitle(mTitle); 
      invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() 
     } 

     /** Called when a drawer has settled in a completely open state. */ 
     public void onDrawerOpened(View drawerView) { 
      super.onDrawerOpened(drawerView); 
      getActionBar().setTitle(mDrawerTitle); 
      invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() 
     } 
    }; 

它說，ic_drawer不能得到解決，用繩子抽屜打開和關閉

同樣需要添加在繪製文件夾命名爲ic_drawer png圖片。並添加字符串strings.xml
