Android, How can I close app when in dialog back button is clicked?

In my main activity, i call a dialog which is cancelable. I show this dialog when user lunches the app while he is not connected to Internet. therefore, I show this dialog to ask him connect to Internet.

This dialog doesn't have button and I want to close application when user clicks back button. In onKeyDown() method, I'm closing the application (this.finish();) but the problem is when dialog is displaying on screen when user clicks back button, this dialog disappear and my main activity is show.

It seems onKeyDown() just work in main activity not for dialog. How to close my app when dialog is display and user clicks back button?

Thanks

=====> Update

This is the code of my custom dialog:

private void initWarningDialog(){
        dialogWarning = new Dialog(DRMActivity.this, R.style.customDialogStyle);
        dialogWarning.setTitle("Warning!");
        dialogWarning.setContentView(R.layout.dialogwarning);
        dialogWarning.setCancelable(true);
    }

Only call finish() method:

dialog.setPositiveButton("Ok",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            // Finish activity
            finish();
        }
    });

Update:

As you are having custom dialog, i would suggest you to set OnCancelListner, something like:

dialogWarning.setOnCancelListener(new OnCancelListener() {
            @Override
            public void onCancel(DialogInterface dialog) {
                // TODO Auto-generated method stub                  

                finish();
            }
 });

Update-2:

It is really annoying because how user can come to know if he press the back key then actual activity will close. Instead you should provide atleast "ok" button to let user click.

OnCancelListener could be useful. 

 alert.setOnCancelListener(new OnCancelListener() {
            @Override
            public void onCancel(DialogInterface dialog) {
                // TODO Auto-generated method stub                  

                finish();
            }
 });

Set OnCancelListener for dialog using setOnCancelListener and finish activity in onCancel method of OnCancelListener.
