Espresso withText in TextView Does not match selected view

Question

I am running an odd test with Espresso. The following is an example of testing TextView in the displayed dialog box. I get the following error:

com.google.android.apps.common.testing.ui.espresso.base.DefaultFailureHandler$AssertionFailedWithCauseError: 'with string from resource id: <2131099772>' doesn't match the selected view.

It is so clear that the view is found, and in it the details you can see text = the value that I expect. But he says that does not match. It starts with the following test instruction

 onView(withId(R.id.dialog_content)).check( matches(withText(R.string.my_content))); 

I also tried to do this with the following statement, but got a NoMatchingViewException even through the View in the hierarchy of the exception view.

 onView(withText(R.string.my_content)).check( matches(isDisplayed())); 

Any help on why this will fail? It is worth noting that I can use withText () isDisplayed () in the kinship field in the dialog box.
