My list view is automatically populating when other users are using my application(Firebase,android)

Question

Im using custom Adapter to populate my list view dynamically.Getting data from firebase realtime database. i dont want application to populate it with users who are using my application.because when everyone is offline listview stays normal. This is whats happening This is how it should be i've tried everything i could. im using myadapter in 3/4 activities

My adapter.java
public class MyAdapter extends ArrayAdapter<String> {
    ArrayList<String> name=new ArrayList<>();
    ArrayList<String> status=new ArrayList<>();
    ArrayList<String> imgs=new ArrayList<>();
    ArrayList<String> key=new ArrayList<>();
    private Context context;
    private int resource;
    private LayoutInflater layoutInflater;

    public MyAdapter(@NonNull Context context, int resource, ArrayList<String> name, ArrayList<String> status, ArrayList<String> imgs,ArrayList<String> key) {
        super(context, resource);
        this.imgs=imgs;
        this.name=name;
        this.status=status;
        this.key=key;
        this.resource=resource;
        this.context=context;
        layoutInflater= (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    @Override
    public int getCount() {
        return name.size();
    }

    @NonNull
    @Override
    public View getView(final int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        //  return super.getView(position, convertView, parent);
        View v=layoutInflater.inflate(resource,parent,false);
        CircleImageView view=v.findViewById(R.id.single_user_image);
        if(imgs!=null) {
            Picasso.get().load(imgs.get(position)).placeholder(R.drawable.user).into(view);
        }else{
            Picasso.get().load(R.drawable.user).into(view);
            Toasty.error(context,"check internet connection", Toast.LENGTH_SHORT).show();
        }
        TextView tv1=v.findViewById(R.id.single_user_name);
        TextView tv2=v.findViewById(R.id.single_user_status);
        tv1.setText(name.get(position));
        tv2.setText("Connected Since:"+status.get(position));
        v.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent=new Intent(getContext(),SingleUserProfileActivity.class);
                intent.putExtra("key",key.get(position));
                getContext().startActivity(intent);

        });
        return v;
    }

Answer 1

I replaced ValueEventListener() to ListenerForSingleValueEvent() as i wanted to show listen for event just once on these pages and thanks to @Victor Maldonado i remembered the difference :P
