Espresso RecyclerViewActions.actionOnItem Fehler

Question

Ich versuche, einen instrumentierten Test in einem meiner Bildschirme, die eine Recycler-Ansicht hat, zu implementieren. Ich habe anscheinend keine Probleme, wenn ich scrollTo() benutze, aber wenn ich actionOnItem() mit dem gleichen View Matcher benutze, bekomme ich eine Laufzeitausnahme.

Jede Hilfe wäre willkommen. Vielen Dank!

Testcode

@Test 
public void nextButton_disabledWhilePhoneNumberInvalid() { 
    onView(withId(R.id.countrycodepicker_enterphonenumber_ccp)).perform(click()); 

    // This is working 
    // onView(withId(R.id.recycler_countryDialog)) 
    //   .perform(scrollTo(hasDescendant(first(withText("Philippines (PH)"))))); 

    // This is also working 
    // onView(withId(R.id.recycler_countryDialog)) 
    //   .perform(actionOnItemAtPosition(1, click())); 

    // This is not working and is causing a PerformException 
    onView(withId(R.id.recycler_countryDialog)) 
      .perform(actionOnItem(hasDescendant(first(withText("Philippines (PH)"))), click())); 

} 

private <T> Matcher<T> first(final Matcher<T> matcher) { 
    return new BaseMatcher<T>() { 
     boolean isFirst = true; 

     @Override 
     public boolean matches(final Object item) { 
      if (isFirst && matcher.matches(item)) { 
       isFirst = false; 
       return true; 
      } 

      return false; 
     } 

     @Override 
     public void describeTo(final Description description) { 
      description.appendText("should return first matching item"); 
     } 
    }; 
}

Answer 1

ich bin nicht wirklich sicher, was Sie mit den ersten() Matcher erreichen wollen, aber meine erste Vermutung wo Leider ist das das, was das Problem verursacht.

RecyclerViewActions.actionOnItem() funktioniert tatsächlich auf der itemView Ihres ViewHolder (die Stammansicht von R.layout.layout_recycler_country_tile). Angenommen, es gibt nur einen Eintrag mit dem Text "Philippines (PH)", der den ersten Matcher entfernt, sollte funktionieren, da actionOnItem bereits eine bestimmte ViewHolder-Zeile betrachtet. Wenn Sie mehrere Zeilen mit demselben Text haben, würde ich vorschlagen, allOf() zu verwenden, um die Zeile, die Sie interessiert, besser zu zielen.
