我有一个活动，其中一些对话框处于打开状态。在这个对话框中有一个微调。我想选择在此微调特定的值，但我得到以下异常：在对话框中选择微调器时，Android espresso中的RunTimeException

我的代码：
protected void selectSpinnerValue(int id, String value) {
onView(withId(id)).perform(click());
onData(allOf(is(instanceOf(String.class)), is(value))).perform(click());
}
的异常情况就行了昂达（allOf ....）
我该如何告诉espresso查看对话框？
尝试使用isPlatformPopup（），它会匹配微调器呈现的窗口 – jeprubio
谢谢你，我怎么用这个？ onData（isPlatformPopup（allOf（is（instanceOf（String.class）））））不起作用 – Peter
我正在从我的手机写信，我认为onData正常，espresso在执行onView代码时抛出异常例如：onView（withId（id））。inRoot（isPlattormPopup（））。perform（click（））;应该管用。试试看，我以前看到过这个例外。 – jeprubio
