Hi,

   This can be done. What I want is a way to use the same button for
showing the progressdialog and later cancelling it. Probably I should
go in for some animated imagview instead of progressdialog for my
requirement, I guess.

Thank you,
B.Arunkumar

Um, unless I'm missing something...

You can't use the same button because presumably the button to launch
the long-running operation is not in the dialog, it's in the activity
- and dialogs prevent interaction with activity UI elements while
displayed.

What you can do is one of:

1) Build your own dialog with a cancel button;

2) Use Dialog.setOnCancelListener which gets called if the user
presses the Back key; here the dialog is dismissed automatically;

3) Set a key listener in the dialog and check for when the back key is
pressed, something like:

mProgressDialog = new ProgressDialog(mActivity);


mProgressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
mProgressDialog.setMax(item.fetch_decoded_size / 1024);

mProgressDialog.setTitle(R.string.attachment_dialog_title);
mProgressDialog.setCancelable(false);
mProgressDialog.setOnKeyListener(new OnKeyListener() {
@Override
public boolean onKey(DialogInterface dialog, 
int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK && 
event.getAction() ==
KeyEvent.ACTION_UP
&& 
event.getRepeatCount() == 0) {
cancelDownload();
return true;
}
return false;
}
});

In this code, canceling the operation can take some time, so I made
the dialog non-cancelable to be able display "Canceling...".

4) Instead of a Dialog, use a
ProgressBar
embedded in
the same layout as the button.
