Created May 10, 2016 18:08 — forked from vaughandroid/ViewVisibilityIdlingResource.java
An IdlingResource for Espresso which blocks until a View has a particular visibility state.

AppCompat-v7:21 provides a very useful way of dealing with pressed/focused/activated states maintaining backwards compatibility downto API-7, but there's a small issue (big for some) with the default selectableItemBackground: It uses some PNGs and/or default values for API<21.
The main reason is that android drawable resource definitions (prior API 21) CANNOT use theme attributes at all, so there's no way of making something like:
<shape android:shape="rectangle">
<solid android:color="?attr/colorControlHighlight" />
</shape>
For this, I've put this simple mockup on how to give your app better drawables that the appcompat defaults.
private boolean isViewVisible(View view) {
Rect scrollBounds = new Rect();
mScrollView.getDrawingRect(scrollBounds);
float top = view.getY();
float bottom = top + view.getHeight();
if (scrollBounds.top < top && scrollBounds.bottom > bottom) {
return true;
} else {
