ActionBar vom AppCompat中的SearchView图标始终有阴影

幸亏 this blogpost ,我设法构建了我的解决方案:

public boolean onCreateOptionsMenu(Menu menu) {
    // the search view is in the mymenu.xml
    inflater.inflate(R.menu.mymenu, menu);

    // now that it is inflated we can get the item
    MenuItem item = menu.findItem(R.id.action_find);

   // and through it the actionview
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
    Drawable searchIcon = getActivity().getResources().getDrawable(R.drawable.ic_action_search); // the new icon

    // and now we search within the view for the "bad" image
    ImageView collapsedSearchIcon = (ImageView) searchView.findViewById(android.support.v7.appcompat.R.id.search_button);

    // and finally replace it
    collapsedSearchIcon.setImageDrawable(searchIcon);
}
