[android-beginners] ProgressDialog Handling

2010-07-24 Thread NIK 
I came across a problem with the ProgressDialog.

I am using a ProgressDialog and a Thread for some networking stuff. I
want the ProgressDialog to be dismissed when the Thread finishes its
work. I am using a Handler to dismiss the ProgressDialog but i don't
know how to continue my
main program flow after the progress dialog. I tried to use a while
loop that called a method from the Thread indicating when the
networking staff was over, but then the ProgressDialog didn't show
until the Thread completed its work.

My code looks like this.

net = new Thread(this.handler);
ProgressDialog.show(this, Title, Message);
while(!net.getResult()){
//Wait
}
//Continue the normal program flow


The only solution that i can think of is to create a method for the
program flow after the ProgressDialog and call that method from the
handler class.

Any ideas on that?

You want to do something after the thread is done ... so at the end of the
thread dismiss the dialog and start the new logic flow.

Well yeah, you're blocking the UI thread which is responsible for showing
the ProgressDialog. If you don't let it continue it will never get to show
the dialog. Never block the UI thread.

Precisely.
