(31, 8): 'ImageView.SetFrame(int, int, int, int)' is inaccessible due to its protection level

I'm learning c# xamarin android. And I experience this problem, trying to edite ImageView object size and position. Can someone explain?

setFrame is a protected method in ImageView, which means it can only be accessed by the ImageView itself or classes that inherit from it. That is why the compiler is telling you that the method is inaccessible.

If you want to set the size for the ImageView programatically you should look into using its Layout parameters (or its parents' parameters) as explained in this question
