Perform Espresso view action on SurfaceView

Issue

I have a class GameView extended from SurfaceView. I added this view in activity_main layout like this:

gameView = new GameView(MainActivity.this);
activity_main = findViewById(R.id.activity_main);
activity_main.addView(gameView);

Now I want to perform any view action (i.e. click) on this SurfaceView using Espresso UI test. So far I came up with this:

DataInteraction surfaceView = onData(instanceOf(GameView.class))
.inAdapterView(withClassName(is("android.view.SurfaceView")));
    surfaceView.perform(click());

But this is not the right way cause it gives the following error:

android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with class name: is "android.view.SurfaceView"

How can I find the view?

Solution

Using getName() solved the problem.

ViewInteraction surfaceView = onView(withClassName(equalTo(GameView.class.getName())));
    surfaceView.perform(click());
