Because while calling this constructor:
CustomListAdapterfriend(Context context, List<HashMap<String, Object>> models)
You are providing getApplicationContext(). Try to provide context of the activity.
Edit 1:
Following the comments:
CustomListAdapterfriend adapter = new CustomListAdapterfriend(Friendsprofile.this, usersList); lv.setAdapter(adapter);

Modify the constructor of your adapter class from
public CustomListAdapterfriend(Context context, List<HashMap<String, Object>> models)
to
public CustomListAdapterfriend(Activity context, List<HashMap<String, Object>> models)
So whenever you call the constructor, the IDE will notify you to provide an Activity as a parameter, so the cast in your adapter won't fail.

While using in fragments try requireActivity() instead of getApplicationContext()
CustomListAdapterfriend(requireActivity(), List<HashMap<String, Object>> models)

How to select more than one photo from the gallery?

I'm building a GIF Creator for my graduation project. What it is, when I try to select from the gallery a photo it just gets it to the view, I want to select more than one photo simultaneously not to go to select photo to get another picture. As well as that I've created a button so if the user changes their mind they can delete and start from scratch not having to restart the application however I don't know what the code is for that.
The main activity:

You can use custom library for multiple image pick like
1) MultiSelectRecyclerGalleryGridView
2) MultipleImagePick

like Kyle Shank answered
https://stackoverflow.com/a/19848052/5090511
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
Or you can use something like that:

java.lang.IllegalStateException:The application's PagerAdapter changed the adapter's contents without calling PagerAdapter#notifyDataSetChanged

I have a sliding image that extends pageradapter. At first it was working. But when i open new activity then press the back button the app is crashing and i've got this error :
