How to get a view from within Espresso to pass into an IdlingResource?

Question

I essentially have a custom IdlingResource that takes a View a constructor argument. I can\'t find anywhere that really talks about how to implemen

Answer 1

Figured it out. To get the view to pass into an idling resource, all you have to do is take the member variable of your ActivityTestRule

For example:

@Rule
public ActivityTestRule activityTestRule = new ActivityTestRule<>(
        MainActivity.class);

and then just call getActivity().findViewById(R.id.viewId)

So the end result is:

activityTestRule.getActivity().findViewById(R.id.viewId);
