डायलॉग में स्पिनर का चयन करते समय एंड्रॉइड एस्प्रेसो में रनटाइम अपवाद

Question

मेरे पास एक गतिविधि है जहां कुछ संवाद खुला है। इस संवाद पर एक स्पिनर है। मैं इस स्पिनर में किसी विशिष्ट मान का चयन करना चाहते हैं, लेकिन मैं निम्नलिखित अपवाद:

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: 
Root{application-window-token=android.view.ViewRootImpl$W@7017bc1, window-token=android.view.ViewRootImpl$W@7017bc1, has-window-focus=false, layout-params-type=1, layout-params-string=WM.LayoutParams{(0,0)(fillxfill) sim=#3 ty=1 fl=#1810100 wanim=0x10303e5 needsMenuKey=2}, decor-view-string=DecorView{id=-1, visibility=VISIBLE, width=1280, height=752, has-focus=true, has-focusable=true, has-window-focus=false, is-clickable=false, is-enabled=true, is-focused=false, is-focusable=false, is-layout-requested=false, is-selected=false, root-is-layout-requested=false, has-input-connection=false, x=0.0, y=0.0, child-count=1}}

मेरे कोड:

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

अपवाद लाइन onData (allof ....)

पर होता है

संवाद में देखने के लिए मैं एस्प्रेसो को कैसे बता सकता हूं?

Answer 1

इस प्रयास करें:

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

Answer 2

मैं एक ही त्रुटि थी जब मैं एक संवाद-टुकड़ा अंदर एक स्पिनर के अंदर एक आइटम से मेल करने की कोशिश की। इससे:

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