Make a view fill a wrap content parent layout

Question

I am trying to add color coding of classes for my android app which organized HW. I am trying to do this by adding a bar on the side with the color of the class. In the image I want the whole layout to wrap the height of the text and then have Shape A fill that layout. I tried to used match parent on shape A which didn't work. After that, what I tried to do was programmatically measure the relative layout and set shape A to the height of that which worked all the time except when the text has to wrap to two lines. All help is appreciated. Thanks!

XML Code: The TV with id side_bar is the side bar I am trying to add.

When you use this as list item, it will have good vision.
