Description Dimitar Dobrev 2015-01-24 06:38:23 UTC
These resources are available to Java (http://stackoverflow.com/a/21291092) but not to C#. As a result, when using android.support.v7.widget.SearchView, I am forced to do this:

// obtain the id by inspecting the visual tree of the search view in the debugger
int searchPlateId = 2131427382;
View searchPlate = searchView.FindViewById(searchPlateId);

I am sure there's no need to explain why this is a horrible "solution". I am aware of this approach:

int searchPlateId = searchView.Context.Resources.GetIdentifier("android:id/search_plate", null, null);

but for some reason it only returns a correct id for the regular (non-support) SearchView.

I am going to try some Java reflection in order to get to android.support.v7.appcompat.R.id.search_plate but even if I make it it will still be ugly so the issue remains.

The following code:

var id = Class.ForName("android.support.v7.appcompat.R$id");
int searchPlateId = (int) id.GetField("search_plate").Get(id);
int searchSrcTextId = (int) id.GetField("search_src_text").Get(id);

works. As you know, Class.getField only retrieves public fields (unlike getDeclaredField) which is further proof that the class should be accessible through C#.

Xamarin.Android 4.x includes an ancient version of the Android support library. Xamarin.Android 5.0 no longer includes the binding; you should instead use the Android Support Component:


The component doesn't appear to provide that member either. Let's see if they have any ideas...

The component includes the SearchView class since version
