Tq Iqbal，我使用工具栏，而不是操作栏 –

如How To show icons in Overflow menu in ActionBar

I移动部件 “setOptionalIconsVisible” 从onMenuOpened到onPrepareOptionsMenu

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    MenuInflater inflater = getMenuInflater(); 
    inflater.inflate(R.menu.main, actionmenu.getMenu()); 

    for(int i=0; i < NavDrawerArray.length; i++) { 
     switch (i) { 
      case 0: 
       icon = R.drawable.ic_action_computer; 
       break; 
      case 1: 
       icon = R.drawable.ic_action_download; 
       break; 
      case 2: 
       icon = R.drawable.ic_action_share; 
       break; 
      case 3: 
       icon = R.drawable.ic_action_important; 
       break; 
      case 4: 
       icon = R.drawable.ic_action_cancel; 
       break; 
      default: 
       break; 
     } 
     menu.add(Menu.NONE, i, Menu.NONE, NavDrawerArray[i]) 
      .setIcon(icon) 
      .setShowAsAction(MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW); 

    } 
    return super.onCreateOptionsMenu(menu); 
}

@Override 
public boolean onPrepareOptionsMenu(Menu menu) { 
    if(menu != null){ 
     if(menu.getClass().getSimpleName().equals("MenuBuilder")){ 
      try{ 
       Method m = menu.getClass().getDeclaredMethod(
        "setOptionalIconsVisible", Boolean.TYPE); 
       m.setAccessible(true); 
       m.invoke(menu, true); 
      } 
      catch(NoSuchMethodException e){} 
      catch(Exception e){} 
     } 
    } 
    return super.onPrepareOptionsMenu(menu); 
}

现在图标可见
