I think I have a problem in my "final Handler handler = new Handler" -
method.
My progressbar declaration is :
progDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
But the handler dismis the dialog only when:
int total = msg.getData().getInt("total");
progDialog.setProgress(total);
if (total <= 0){
dismissDialog(0);
progThread.setState(ProgressbarThread.DONE);
}
But I have no "total".
So I have no condition to call dismissDialog, or?
Does someone has an idea, how i can handle this?
