Well,
The approach I follow is this:
Of-course, what you have observed is right. You are blocking the UI
thread. And, calling dismiss, after show, will obviously dismiss the
dialog, instantly.
So, Whenever you need to show a progress dialog, call show method from
the UI Thread, and then start another thread, where you do your work.
>From within that thread, you need to call a handler, which then
dismissed the dialog.
Something like this.
Your Activity should implement Runnable.
pDialog.setMessage("Your Message");
pDialog.show();
Thread workerThread = new Thread(this);
workerThread.start();
Now in your run method, do whatever you want, but after you finish,
call the handler...
public void run(){
//do work...
handler.sendEmptyMessage(0);
}
private Handler handler = new Handler(){
public void handleMessage(int what){
pDialog.dismiss();
}
};
