Question

Hello and thanks for help I have asked here how to Polpulate listview from firebase and thankfully Krishna Kishan solved my problem but now what I like to do is when I click on

Answer 1

You have to modify some code that is outside the snippet you posted.

I guess your items are read from the database. When you read your "message" node you have to save keys as well as values. You can achieve this in a number of ways. e.g.

final ArrayList keyList = new ArrayList<>();
final ArrayList items = new ArrayList<>();
myRef.getRoot().child("messages")
        .addListenerForSingleValueEvent(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        for (DataSnapshot messages : dataSnapshot.getChildren()) {
            keyList.add(messages.getKey());
            items.add(messages.getValue(String.class));
        }
    }
    @Override
    public void onCancelled(DatabaseError databaseError) {
        /*handle errors*/
    }
});

Now you have both keys and values. Modify your OnClickListener this way:

listi.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView parent, View view, int position, long id) {
        items.remove(position);
        adapt.notifyDataSetChanged();
        //new code below
        myRef.getRoot().child("message").child(keyList.get(position)).removeValue();
        keyList.remove(position);
    }
});

Obviously listi.setOnItemClickListener( ... ) should be called when both keyList and items are properly filled. Please notice that ValueEventListener is asynchronous.
