Question

I have created a ProgressDialog in my android application. But the problem I am having is during the point where it is actually doing the work it stops spinning the wheel. Here is my code. How can I make it so it continually spins the wheel while my other work is going on?

button5.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
    System.out.println("Button5");

    //Handler to make the please wait message
    final ProgressDialog myProgressDialog = ProgressDialog.show(
            FoodSubstitutesActivity.this, "Please wait...",
            "Getting most recent updates...", true);
    Handler handler = new Handler();
    handler.postDelayed(new Runnable()
    {
        @Override
        public void run()
        {
            //DO STUFF - STOPS SPINNING WHEEL UNTIL THIS PART IS COMPLETE. 
            myProgressDialog.dismiss();
        }

    }, 500);
}
});

Why dont you try doing it this way?

final ProgressDialog dialog = ProgressDialog.show(this, "Title", 
"Message", true);
final Handler handler = new Handler() {
   public void handleMessage(Message msg) {
      dialog.dismiss();
      }
   };
Thread checkUpdate = new Thread() {  
   public void run() {
//
// YOUR LONG CALCULATION (OR OTHER) GOES HERE
//
      handler.sendEmptyMessage(0);
      }
   };
checkUpdate.start();
