Dialog with multiple buttons(cancalButton, deleteButton) is showed when click button in recyclerview item.
So I made two listener(cancelListener, deleteListener).
Show dialog is successful and cancelListener works well, But I can't do what I want in delteListener.
I wanna delete data in firebase when user click delete button in dialog.
So I have to know clicked recyclerview item's position to find data. (Because I can find data by getting key from array.get(position).getTimestamp.
How can I get item position in deleteListener?

Since your method private void openDialog(final int position) has the position information. One of the way you can do it is just by creating a class for deleteListemer (DeleteListenerWithItemPos) and then pass the position as an argument at the constructor.
An example of how to implement is shown as follows:
private void openDialog(final int position){
deleteListener = new DeleteListenerWithItemPos(position);
dialog = new DialogDeletePin(context,cancelListener, deleteListener);
dialog.setCancelable(true);
dialog.getWindow().setGravity(Gravity.CENTER);
dialog.show();
}
View.OnClickListener deleteListener;
public static class DeleteListenerWithItemPos implements View.OnClickListener() {
private int itemPos;
public DeleteListenerWithItemPos(int itemPos){
this.itemPos = itemPos;
}
public void onClick(View v) {=
itemPos; //get itemPos here
Log.d("####dialog","click delete");
dialog.dismiss();
}
}
