    <item android:drawable="@drawable/edit_focused" android:state_pressed="true" />
    <item android:drawable="@drawable/edit_normal" android:state_focused="false" />
    <item android:drawable="@drawable/edit_normal" android:state_pressed="false" />
</selector>

    <solid android:color="#95D4C8" />
    <corners android:radius="10dip" />
    <stroke
        android:width="2dip"
        android:color="#95D4A0" />
</shape>
