Cards can't be swiped when changes are made after setAdapter()

[hong-yew]

To reproduce:

After setAdapter(), add a card to the adapter using the adapter's add(), which internally will call notifyDataSetChange(). However, after this point, the card cannot be swiped.

The problem lies in mTopCard being set to null when adapter nofityDataSetChange() gets called, the CardContainer's data listener onChanged() calls clearStack() which clears sets mTopCard = null.

After that mTopCard is always null unless setAdapter() is called again, which shouldn't have to be.

Suggest to move the code in setAdapter()

if (getChildCount() != 0) {
           mTopCard = getChildAt(getChildCount() - 1);
            mTopCard.setLayerType(LAYER_TYPE_HARDWARE, null);
        }

to ensureFull() which is just the line above. This will ensure that notifyDataSetChange() will work as intended without having to call setAdapter() again (which the code shouldn't have access to the view element to call).
