I seeking for this:

Answer 1

Try below Code

ProgressDialog for showing:

 ProgressDialog mDialog = new ProgressDialog(getApplicationContext());
                mDialog.setMessage("Loading...");
                mDialog.setCancelable(false);
                mDialog.show();

After cancel ProgressDialog below code:

 mdialog.dismiss();

Answer 2

This is basically done with an AsyncTask and a ProgressDialog (Using spinner style) that is started and dismissed by the AsyncTask.

Answer 3

You can not start/end ProgressDialog from any thread other that UI thread. In it's simplest for you would want to use AsyncTask methods onPreExecute onPostExecute. But I would be careful with that.

1. you don't want to lose a reference to dialog from async task (user changes orientation or rotates the screen). So you want to keep WeakReference to dialog
2. If you're doing serious loading worj, I'd recomment using Service for it and listening for service callbacks (like broadcasts) to control dialog. This will also allow you separate Activity lifecycle from background work.
