推荐答案

我发现这样做觉得─使用反射的唯一途径。

I've found the only one way to do that- to use reflections.

SearchView mSearchView = (SearchView)menu.findItem(R.id.search).getActionView();
    try
    {
        Field searchField = SearchView.class.getDeclaredField("mSearchButton");
        searchField.setAccessible(true);
        ImageView searchBtn = (ImageView)searchField.get(mSearchView);
        searchBtn.setImageResource(R.drawable.search_img);
        searchField = SearchView.class.getDeclaredField("mSearchPlate");
        searchField.setAccessible(true);
        LinearLayout searchPlate = (LinearLayout)searchField.get(mSearchView);
        ((ImageView)searchPlate.getChildAt(0)).setImageResource(R.drawable.search_img);
        searchPlate.setBackgroundResource(R.drawable.edit_text_bkg);
    }
    catch (NoSuchFieldException e)
    {
        Log.e(TAG,e.getMessage(),e);
    }
    catch (IllegalAccessException e)
    {
        Log.e(TAG,e.getMessage(),e);
    }
