If a user clicks/taps on an item, you'll get the position of that item from Android.

With that you can call adapter.getRef(position).remove().

Puf, how can you delete the item from the viewholder?

[astromme]

@puf, I'm also wondering how you delete the item from the viewholder? Seems like the viewholder doesn't know about the adapter.

[SUPERCILEX]

@astromme Simply create a DatabaseReference setter in your viewholder:

public void setRef(DatabaseReference ref) {
    mRef = ref;
}

// Do other stuff like setting a click listener

Yes Me to I have the same probleme i want to delete only from the View (recyclerview ) and not for the database ! any solutions ! ?

[driexyz]

i have an item using a relative layout for view holder in recycleview, it have an id to declare it in code. so when populating view to bind the data on viewholder i just need to call removeAllViewsInLayout() to make it dissapear from recycleview and not delete the real data on firebase.

        @Override
        public void onChildAdded(@NonNull DataSnapshot dataSnapshot, @Nullable String s) {

            CourseModel courseModel=dataSnapshot.getValue(CourseModel.class);
            courseModelslist.add(courseModel);
            arrayKeyList.add(dataSnapshot.getKey());
            courseAdapter=new CourseAdapter(RetriveCourse.this,courseModelslist);
            recyclerView.setAdapter(courseAdapter);
            courseAdapter.notifyDataSetChanged();

// for (DataSnapshot ds:dataSnapshot.getChildren())
// {
// CourseModel courseModel=ds.getValue(CourseModel.class);
// courseModelslist.add(courseModel);
//
// }
// courseAdapter=new CourseAdapter(RetriveCourse.this,courseModelslist);
// recyclerView.setAdapter(courseAdapter);
// courseAdapter.notifyDataSetChanged();

        }

        @Override
