onView (withId (R.id.menu_delete)).check (matches (not (isDisplayed ())));

…但它抛出了这个异常：

android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with id: com.just10.android:id/menu_delete
If the target view is not part of the view hierarchy,you may need to use Espresso.onData to load it from one of the following AdapterViews:com.github.ksoichiro.android.observablescrollview.ObservableListView{3169f0f3 VFED.VC. .F...... 0,0-480,724 #102000a android:id/list}

不应该显示断言视图的最佳方法是什么？
