问题
I am trying to access a button from a specific view. The same view is displayed 6 times. This is the code I am using.
public void testTimeConfig(){
onData(withDesc("description")).onChildView(withId(R.id.positive)).perform(click());
}
private static Matcher<Object> withDesc(String desc) {
return allOf(is(instanceOf(String.class)), is(desc));
}
When I run, I get an error:
Error performing 'load adapter data' on view 'is assignable from class: class android.widget.AdapterView'.
Is this the best way to access a child view? If so, how?
EDIT
This is the code I am trying to use now.
onView(allOf((withContentDescription("description")), hasSibling(withContentDescription("SettingsLayout")), hasSibling(withId(R.id.positive)))).perform(click());
and
onView(allOf((withContentDescription("description")), hasSibling(withId(R.id.positive)))).perform(click());
With this Error:
No views in hierarchy found matching

It is the ImageView with id increaseGoalButton that I am trying to click.
回答1:
Based on your last comment you should use onView() instead of onData().
I think you'll be able to click the button using hasSibling() - example
onView(allOf(withId(R.id.positive), hasSibling(withDesc(someString))))
.perform(click());
or examples without your custom matcher (sibling view has text):
onView(allOf(withId(R.id.positive), hasSibling(withText(someString))))
.perform(click());
or (sibling view has content description):
onView(allOf(withId(R.id.positive), hasSibling(withContentDescription(someString))))
.perform(click());
EDITED:
OK, I'd try these two variants:
onView(allOf(withId(R.id.increaseGoalButton), isDescendantOfA(withId(R.id.timeGoalWidget))))
.perform(click());
or
onView(allOf(withId(R.id.increaseGoalButton), withParent(withId(R.id.timeGoalWidget))))
.perform(click());
回答2:
None of your content descriptions match the string "description" that's why it doesn't find anything.
回答3:
Assuming the button id is R.id.positive, and the id is unique in the current activity view, you can simply use:
onView(withId(R.id.positive)).perform(click());
