Android ActionBar compatibility: MenuItem.setActio

问题:

I'm using the appcompat7 lib for ActionBar backwards compatibility. Now I have a MenuItem that I retrieve, and then want to set an ImageView myView as its icon.

The way how to do it from API level 11 is:

MenuItem menuItemRefresh = menu.findItem(R.id.refresh);
menuItemRefresh.setActionView(myView);

For API levels lower than 11 this doesn't work, the second line will show an error. Is there an option to do this in compatibility mode?

Look at MenuItemCompat: http://developer.android.com/reference/android/support/v4/view/MenuItemCompat.html

There is a static function setActionView(MenuItem item, View view)

So your code should look like:

MenuItem menuItemRefresh = menu.findItem(R.id.refresh);
menuItemRefresh = MenuItemCompat.setActionView(menuItemRefresh, myView);
