Issue
I have to display a recyclerview inside a PopupWindow after a Volley call. I'm able to get the data after volley call and display it in the activity or a spinner but I not sure how to do that in a PopupWindow. Since I dont get where to initialize the recycleview and the adapter. Kindly tell me where shall I call the GET_MALL_WEB_CALL() mathod and how to pass the data into the popup window, so that I can access the data on the popup window. Could any one help in achieving this.Should I do this in some other way? I'm kinda stuck here.

Solution
Remove following from onCreate()
LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
mallRecyclerView = findViewById(R.id.recyclerView);
mallRecyclerView.setLayoutManager(layoutManager);
mallRecyclerAdapter = new MallAdapter(this);
mallRecyclerView.setAdapter(mallRecyclerAdapter);
You have to rewite the showPopup()
public void showPopup(View view){
//Create a View object yourself through inflater
LayoutInflater inflater = (LayoutInflater) view.getContext().getSystemService(view.getContext().LAYOUT_INFLATER_SERVICE);
View popupView = inflater.inflate(R.layout.layout_mall_recycler, null);
//Specify the length and width through constants
int width = LinearLayout.LayoutParams.MATCH_PARENT;
int height = LinearLayout.LayoutParams.MATCH_PARENT;
//Make Inactive Items Outside Of PopupWindow
boolean focusable = true;
//Create a window with our parameters
final PopupWindow popupWindow = new PopupWindow(popupView, width, height, focusable);
//Set the location of the window on the screen
popupWindow.showAtLocation(view, Gravity.CENTER, 0, 0);
//Initialize the elements of our window, install the handler
LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
mallRecyclerView = popupView.findViewById(R.id.recyclerView);
mallRecyclerView.setLayoutManager(layoutManager);
mallRecyclerAdapter = new MallAdapter(this);
mallRecyclerView.setAdapter(mallRecyclerAdapter);
GET_MALL_WEB_CALL();
//Handler for clicking on the inactive zone of the window
popupView.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
//Close the window when clicked
popupWindow.dismiss();
return true;
}
});
}
