I need to adjust somehow the FirebaseRecyclerAdapter in order to get some data from my database and not all of them. Is there any way to achieve that? My end goal is to show 10 random entries on the screen! Here is what I tried and the results:
FirebaseRecyclerAdapter<Houses, HousesViewHolder> mHousesRecyclerAdapter = new FirebaseRecyclerAdapter<Houses, HousesViewHolder>(
Houses.class,
R.layout.house_single,
HousesViewHolder.class,
mDatabaseHouses
) {
@Override
protected void populateViewHolder(HousesViewHolder viewHolder, Houses house, int position) {
if (Integer.parseInt(house.getPrice()) > 200) {
viewHolder.setHouseName(house.getHouse_name());
viewHolder.setCity(house.getCity());
viewHolder.setImage(house.getMainFoto(), getApplicationContext());
viewHolder.setPrice(house.getPrice());
}
}
};
mRecyclerView.setAdapter(mHousesRecyclerAdapter);
The entries with the google logo are the houses that have price < 200 and are the houses in this example that I do not them to be appeared at all.
