View source for Action: Set Button Bar Image

This action can be used to change the image of a button within the MacroDroid notification button bar.

Each instance of the action can used to modify a single button bar image specified as the button number from 1-7. 

This action is useful if you want to represent a button as a toggle and have more than one state depending on the state of the toggle. You could also use a series of these action to change the entire bar state if you wanted to support different appearance of the entire button bar based on some context.
