Questions:

I have an activity where some dialog is openend. On this dialog there is a spinner. I want to select a specific value in this spinner, but I get following exception:

java.lang.RuntimeException: Waited for the root of the view hierarchy to have window focus and not be requesting layout for over 10 seconds. If you specified a non default root matcher, it may be picking a root that never takes focus. Otherwise, something is seriously wrong. Selected Root:

My code:

 protected void selectSpinnerValue(int id, String value) {
    onView(withId(id)).perform(click());
    onData(allOf(is(instanceOf(String.class)), is(value))).perform(click());
}

The exception happens on the line onData(allOf….)

How can I tell espresso to look in the dialog?

This helped:

onView(withText(value)).inRoot(isPlatformPopup()).perform(click());

Try this:

onData(allOf(is(instanceOf(String.class)), is(value)))
    .inRoot(isPlatformPopup()).perform(click());
