I have a linear layout which consists of imageview and textview , one below another in a linear layout.
I solved the same problem by add android:elevation="1dp" to which view you want it over another. But it can't display below 5.0, and it will have a little shadow, if you can accept it, it's OK.
android:elevation="1dp"
So, the most correct solution which is @kcoppock said.
