Android Espresso单击ListView内的按钮

Question

I'm trying to make a test with Espresso that performs a click on a button within a specific element of my Listview.

Each element in the ListView has aa button (R.id.my_button) and I want to click the button of the first element.

I tried: onData(anything()). atPosition(0). inAdapterView( allOf( withId(R.id.my_button) ) ). perform(click());

Actual result: androidx.test.espresso.AmbiguousViewMatcherException: '(with id: com.test.test:id/my_button)' matches multiple views in the hierarchy.

Answer 1

如果要进入AdapterView，可以单击listview中的元素

onData(anything()).inAdapterView(withId(R.id.list1)).atPosition(0).perform(click());

Answer 2

这可能会有所帮助，进入listView->第一个元素->第一个元素的子对象（在您的情况下为按钮）

onData(anything()).inAdapterView(withId(R.id.list)).atPosition(0).onChildView(withId(R.id.my_button)).check(matches(isDisplayed())).perform(click());
