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. |
