please help me figure our.thank you!

try changing

**<view android:id="@+id/overlay" android:layout_width="260dp" android:layout_height="20dp" android:layout_below="@+id/lbl_balance" />**

to

**<view android:id="@+id/overlay" android:layout_width="260dp" android:layout_height="20dp" android:layout_alignbottom="@+id/heart_imageview" />**

changes made: layout alignment , id of whom aligned
