I am working on an Android app.
There is an activity with two independent recyclerviews.
The first one is horizontal and has its own adapter. The second one is vertical and has also its own adapter.
The first time the activity is started, both recyclerviews show all items from their respective sources.
But later I need to filter the items to be shown on the second recycler view depending on the selected item from the first recyclerview.
At the first adapter, when an item is clicked I get the id from it, which I could use to filter the items from the second recyclerview.
Which is the best way to pass the id from the first recyclerview clicked item to the second recyclerview with no need to reload the activity?
Here is the way I am getting the id from the first adapter:
class MenuClickListener implements PopupMenu.OnMenuItemClickListener {
Integer pos;
public MenuClickListener(int pos) {
this.pos = pos;
}
@Override
public boolean onMenuItemClick(MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.action_favourite:
String positi = marcaList.get(pos).getnombre();
Integer positid = marcaList.get(pos).getId();
return true;
default:
}
return false;
}
}
Both recyclerviews are populated from a remote database.
