How to get View from Matcher<View>

Question

How do I get the View from a Matcher?

I need to get the bitmap from a specific element which findbyview is not giving specifically but I could get it by specifying more matchers

Answer 1

Use the check method of ViewInteraction and implement a custom ViewAssertion

Example in Kotlin:

onView(TODO("ADD YOUR MATCHER")).check { view, noView ->
    // Get bitmap here
}

Example in Java:

onView(/* TODO("ADD YOUR MATCHER") */).check(new ViewAssertion() {
    @Override
    public void check(View view, NoMatchingViewException noViewFoundException) {
        // Get bitmap here
    }
});
