Finding a resource given its ID - as a variable


Finding a resource in your layout is easy if you know the id:

LinearLayout l = FindViewById<LinearLayout>(Resource.Id.linearLayout1);

but say I have

String id = "linearLayout1";

How can I access the resource IDs and "find" the one I'm looking for?


Solution

  • You can use this: Resources#getIdentifier()

    String id = "linearLayout1";
    
    int resourceId = getResources().getIdentifier(id, "id", getPackageName());
    

    Edit:

    I didn't see the Xamarin tag. I am not familiar with Xamarin, but as far as I know, it mimics the Android API, so there should be a similar method available for that.
