In Android test, how to check that view is displayed?

I am writing a test UI example (using ActivityUnitTestCase) and would like to check if the view of the View subclass is currently visible to the user. I found the View # isShown () method , which claims to do just that - checking the field of view of this element and all its parents - but for some reason it always returns false for all elements. I will be grateful for the help. If this simplifies, I can insert the code.

In addition, I found ViewAsserts # assertOnScreen (View start, View view) , but it also does not work correctly - it always returns true. Perhaps I called it wrong: assertOnScreen (viewImTesting.getRootView (), viewImTesting)?

Thanks, Jan

I found a reasonable workaround: simply by checking View # getVisibility () against View # VISIBLE , VIEW # INVISIBLE or VIEW # GONE .

This probably does not work when, for example, the parent view is not displayed, but it has the visibility set to VISIBLE, but in most cases this should be enough.

Try using

final View origin = activityImTesting.getWindow().getDecorView();
android.test.ViewAsserts.assertOnScreen(origin, viewImTesting);
