Question

我遇到了奇怪的浓缩咖啡仪器测试行为。单击回收站视图的项目不起作用。

点击此处未发生：

onView(withId(R.id.recyclerView)).perform(actionOnItemAtPosition(0, click()));

但是这种解决方法有效：

onView(withId(R.id.recyclerView)).perform(actionOnItemAtPosition(0, recyclerClick()));

// ...

public static ViewAction recyclerClick() {
    return new ViewAction() {

        @Override
        public Matcher<View> getConstraints() {
            return any(View.class);
        }

        @Override
        public String getDescription() {
            return "performing click() on recycler view item";
        }

        @Override
        public void perform(UiController uiController, View view) {
            view.performClick();
        }
    };
}

这是Espresso还是RecyclerView问题？

Answer 1

应该与RecyclerView具体无关。 Espresso的ViewActions.click()实施功能将MotionEvent发送到目标视图的中心。确保没有孩子拦截它。

Answer 2

您可以使用RecyclerViewActions

只需使用：

onView(withId(R.id.recyclerView)).perform(
            RecyclerViewActions.actionOnItemAtPosition(0, click()));

例如：

@RunWith(AndroidJUnit4.class)
public class MainActivityTest {
  @Rule
  public ActivityTestRule<MainActivity> activityRule = new ActivityTestRule<>(MainActivity.class);

  @Test
  public void clickItem() {
    onView(withId(R.id.recycler_view))
        .perform(RecyclerViewActions.actionOnItemAtPosition(o, click()));

    onView(withId(R.id.text))
        .check(matches(withText("XX")))
        .check(matches(isDisplayed()));
  }
}

RecyclerView espresso测试点击（）不起作用
