Android Espresso ListView click item

问题:

I have ListView with pictures and text. When I try to click item, I get error

android.support.test.espresso.AmbiguousViewMatcherException: 'with id: com.cifrasoft.telefm:id/cardsGridView' matches multiple views in the hierarchy.
Problem views are marked with '****MATCHES****' below.

I use the following code:

onData(hasToString(startsWith("Item Text")))
            .inAdapterView(withId(R.id.cardsGridView))
            .perform(click());

Can I click ListView using position of Adapter, without matches or startWith?

回答1:

Try with atPosition(). e.g.

onData(hasToString(startsWith("Item Text")))
            .inAdapterView(withId(R.id.cardsGridView)).atPosition(0)
            .perform(click());

with index 0, it will click on the first matching view found.

Use Record Test to obtain the ViewInteraction of the list then obtain the view and use performItemClick as follows:

AtomicReference<ListView> resultView = new AtomicReference<>(null);
ViewInteraction viewInteraction1 = onView( ... withId(R.id.my_list_id), ...);
viewInteraction1.check(((view, noViewFoundException) -> {
    if(noViewFoundException != null){
        return;
    }

    resultView.set((ListView) view);
}));

if(resultView.get() != null){
    ListView listView = resultView.get();
    activity.runOnUiThread(()->{
        listView.performItemClick(
            listView.getAdapter().getView(index, null,null),
            index,
            listView.getAdapter().getItemId(index));
    });
}
