I have a RecyclerView that displays a list of applications currently installed on the device. Each row includes the name of the application, its package name, and a switch. When the Switch isChecked, the package name is added to an ArrayList. If the user clicks back into that Activity, I need to repopulate the list and set the state of Switches based on what was previously added to the ArrayList.
The overall idea I have is to do a comparison of the package names in the RecyclerView to those stored in the ArrayList, and when there is a match the Switch for that row needs to be set to checked.
The problem is that I am not sure how to best accomplish this. I think it needs to be done in the Activity and not the Adapter, since there is on onCreate() in the Adapter. I know it is also going to involve a loop.
Anyone have any idea how to do this?
