How Can to test by Espresso android.widget.TextView setError?

Issue

I have password.setError(getResources().getString(R.string.incorrect_data)); If I set invalid password - show textView with text "Invalid data!", I need to test it by Espresso, I write:

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

But it is wrong, I have:

android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with string from resource id: <2131493034>[incorrect_data] value: Invalid data!
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:android.widget.ListView{307b4f3a IFED.VC. ......ID -480,0-0,1022 #7f0a004c app:id/left_drawer}

And If I write: onView(withText("Invalid data!")).check(matches(isDisplayed()));

I have:

android.support.test.espresso.NoMatchingViewException: No views in hierarchy found matching: with text: is "Invalid data!"
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:android.widget.ListView{307b4f3a IFED.VC. ......ID -480,0-0,1022 #7f0a004c app:id/left_drawer}

I use Espresso 2:

import static android.support.test.espresso.assertion.ViewAssertions.matches;
import static android.support.test.espresso.matcher.ViewMatchers.withText;
import static android.support.test.espresso.Espresso.onView;

Help me, please.

Solution

helped me:

onView(withId(R.id.password)).check(matches(withError(
                getActivity().getString(R.string.incorrect_data))));

private static Matcher<View> withError(final String expected) {
        return new TypeSafeMatcher<View>() {

            @Override
            public boolean matchesSafely(View view) {
                if (!(view instanceof EditText)) {
                    return false;
                }
                EditText editText = (EditText) view;
                return editText.getError().toString().equals(expected);
            }

            @Override
            public void describeTo(Description description) {

            }
        };
    }
