I have a RecyclerView with list of users, where in UI shows username of each user.
The text color is per default is black and I would like to change it to another color. There is no property for textColor so I guess it should be done programmatically
...ANSWER
Answered 2022-Mar-25 at 10:56Normally your recyclerView contains an adapter. The adapter holds/binds a list of UI elements (your users). So in my opinion, you have to change the colour of the user elements in your custom adapter class

fragment = new PlaceholderFragment();
When `busStopInterface.getBusStop()` get return, you set data to
private PlaceholderFragment fragment
and fragment is not attach to any Activity,so UI dosen't refresh.
You should get PlaceholderFragment instance from SectionsPagerAdapter or create PlaceholderFragment instance for SectionsPagerAdapter, and you can set data to real PlaceholderFragment
