i'm sorry for the weird title but i didn't find other ways to explain that.
In a Fragment i have a ProgressDialog that has to be shown till every instructions inside the Fragment are completed. The problem is that it disappear 5 seconds before the layout has to be changed.
Here is my code:
final View view = inflater.inflate(R.layout.fragment_lista, container, false);
GridView gv = (GridView) view.findViewById(R.id.gridView);
Gson gson = new GsonBuilder().serializeNulls().create();
ProgressDialog progressDialog = ProgressDialog.show(getActivity(), "", "Loading...", true);
new Thread(new Runnable() {
@Override
public void run()
{
String urlLista = null;
try {
urlLista = connection("https://www.something.com"); //personal method for this connection
} catch (IOException e) {
e.printStackTrace();
}
String listaTrimmed = urlLista.trim();
ListaManga listaManga = gson.fromJson(listaTrimmed, ListaManga.class);
List prov = new ArrayList();
for (int i = 0; i < 15; i++) {
prov.add(listaManga.getManga().get(i));
} //ArrayList of 15 elements
GridAdapter gridadapter = new GridAdapter(getActivity(), prov); //custom adapter
});
getActivity().runOnUiThread(new Runnable() {
@Override
public void run()
{
progressDialog.dismiss(); //Here is when the ProgressDialog obviously disappear
gv.setAdapter(gridadapter);
gridadapter.notifyDataSetChanged();
}
});
}
}).start();
If i have to be honest i expected that with my code, after the dismiss() of the ProgressDialog, everything in this Fragment would be successfully loaded but it isn't. I have to wait 5 more seconds till everything is loaded and i can't understand why, hope i'll get some answers here. If there are some questions about my code, just ask, i had to cut a lot of parts of it and i couldn't explain this question better sorry. I tried also to put the dismiss() of the ProgressDialog inside a post delayed Handler, it worked, but i cancelled the animation of the ProgressDialog.
