Espresso not triggering SelectionTracker

[aljohnston112]

Description

A longClick() with RecyclerViewActions.actionOnItemAtPosition does not trigger the selection of the item in a RecyclerView that has been passed to a SelectionTracker.

Steps to Reproduce

Set up a SelectionTracker with a RecyclerView in a Fragment.

Use launchActivity and onActivity set the Fragment to the Activity.

longClick() an item in the RecyclerView

Notice that nothing was selected.

It is worth noting that if debugging, and at a breakpoint, if you manually longClick(), a selection will be triggered.

Expected Results

The SelectionTracker to be triggered by a longClick() on an item in the RecyclerView passed to it, therefore triggering a selection.

Actual Results

The SelectionTracker was not triggered by a longClick() on an item in the RecyclerView passed to it, and a selection was not triggered.

        val cdl  = CountDownLatch(1)
        scenario.onActivity {
            val recyclerView = it.findViewById<RecyclerView>(R.id.fragment_editor_recycler_view)
            val ite = recyclerView.getChildAt(0)
            ite.getLocationOnScreen(location)
            cdl.countDown()
        }
        cdl.await()
        onView(isRoot()).perform(
            GeneralClickAction(
                Tap.LONG,
                { FloatArray(location.size){ i -> (location[i]+1).toFloat() } },
                Press.FINGER,
                InputDevice.SOURCE_UNKNOWN,
                MotionEvent.BUTTON_PRIMARY
            )
        )

Long click still does not trigger SelectionTracker when clicked through the root view. I have verified it is connected to the Fragment's RecyclerView. This is clearly a bug.

InputDevice seems to be the culprit. Changing the default value to something like SOURCE_TOUCHSCREEN or SOURCE_MOUSE triggered the SelectionTracker for us.

- ViewActions.click()
+ ViewActions.click(InputDevice.SOURCE_TOUCHSCREEN, MotionEvent.BUTTON_PRIMARY)

I'm not sure what changed between 1.5.0 betas and 1.5.0 stable though.
