Not able to select an item from AutoCompleteTextView dropdown using Espresso

Issue

Following is the snapshot of my AutoCompleteTextView dropdown, from which I'm trying to select 2nd item

My Espresso Code:

onView(withId(R.id.searchContainer)).check(matches(isDisplayed()));
onData(anything())
      .inAdapterView(withId(R.id.searchContainer))
      .atPosition(1)
      .perform(click());

But I'm getting following Exception:

android.support.test.espresso.PerformException: Error performing 'load adapter data' on view 'with id: com.sampleaddressdd.demo:id/searchContainer'

With Espresso Recorder I get following code:

DataInteraction appCompatTextView = onData(anything())
                .inAdapterView(childAtPosition(
                        withClassName(is("android.widget.PopupWindow$PopupBackgroundView")),
                        0))
                .atPosition(0);
        appCompatTextView.perform(click());

Dropdown inflater code :

        mSearchView = findViewById(R.id.textSearch);
        mSearchView.setDropDownAnchor(R.id.searchContainer);
        mHttpClient.fetchAddresss(new HttpClient.AddressCallback() {
            @Override
            public void run() {
                mAdapter = new AddressAdapter(MainActivity.this, mAddresss, new AddressAdapter.OnAddressClickCallback() {
                    @Override
                    public void execute(Address Address) {
                        startActivity(AddressProfileActivity.createIntent(MainActivity.this, Address));
                    }
                });
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        mSearchView.setAdapter(mAdapter);
                    }
                });
            }
        });

Solution

Finally Achieved this with the use of :

onView(withText(LOCATION_TO_BE_SEARCHED)) .inRoot(withDecorView(not(mActivityTestRule.getActivity().getWindow().getDecorView()))) .check(matches(isDisplayed())) .perform(click());
