Al, just some suggestions but are you managing your progress dialog
from the worker thread?
Perhaps I can help if I describe what I did in my app.
My main activity view has a function 'updateData' which launches the
background thread to fetch the data for the view. Inside the'
updateData' I call 'showDialog' with the id of the busy dialog so:
showDialog(LOADING_DIALOG_KEY);
this is _prior_ to launching the worker thread. When the results are
returned the worker thread calls a function in the main activity
'showData' which clears the busy dialog with
dismissDialog(LOADING_DIALOG_KEY);
and updates the view. That is, the busy dialog is launched and cleared
from the main activity.
I implemented the onCreateDialog fn:
protected Dialog onCreateDialog(int id)
{
switch (id)
{
case LOADING_DIALOG_KEY:
{
ProgressDialog dialog = new ProgressDialog(this);
dialog.setMessage("Updating Forecast...");
dialog.setIndeterminate(true);
dialog.setCancelable(true);
return dialog;
}
default:
break;
}
return super.onCreateDialog(id);
}
The problem I was seeing then was that when I switched the orientation
of the phone when the dialog was active it was never being closed.
I was calling the initial data fetch in the onCreate from my main
activity. When I moved it to the onResume the problem went away. I had
then to ensure that only the first 'onResume' call triggered the
initial data fetch otherwise every time I returned from an activity
launched from the main (like a properties view) it reloaded the data
regardless. I just did this with a flag which was initialised on
creation of the activity.
So, I guess what I am suggesting is that you move the function which
fetches the data into the main activity, pass a references to the
activity to the worker thread, only deal with the progress dialog by
calling fns from the main activity and implement the onCreateDialog
fn.
Al.
