Answer 1

You can check the Enabled status of the button after entering the text in the EditText by using:

onView(withId(R.id.yourButtonId)).check(matches(isEnabled()))

Or you can also check whether it is disabled by using:

onView(withId(R.id.categoryContinueBtn)).check(matches(not(isEnabled())))
