Workaround for Popup anchor scroll issue tracked at https://code.google.com/p/android/issues/detail?id=135439

PopupAnchorTextView.java

import android.content.Context;
import android.graphics.Rect;
import android.support.v7.widget.AppCompatTextView;
import android.util.AttributeSet;

/**
 * Single purpose TextView to be used as a Popup anchor while it is a child of a scrolling
 * container. When a support-v4 popup is shown with an anchor that is inside a scrolling container,
 * the observed behaviour is that the container is scrolled so the anchor is at the top of the
 * container and fully visible.
 * <p>What we do here is {@linkplain #requestRectangleOnScreen consume the request} that would
 * result is the container being scrolled.

Hi! Thanks for this, it works! One thing I noticed thought, if you scroll and make your anchor partially visible (from the bottom) and you click on it, then the popup will cover some part of the bottom bar (the one with the back button, etc). Do you know if that is a bug or would be intended to happen?
