In 2.3 APIver 9  AndroidFloatLabel-API9 float_label shadowed by edit_text , we need remove android:layout_marginTop="-7dp"  in EditText I guess!

Possible solution:   Looks like we need to implement 
 layout (without android:layout_marginTop="-7dp"), 

layout-v11,
layout-v14 (with android:layout_marginTop="-7dp")

layout folder in the library project !
