How to handle Back button with in the dialog?

dialog.setOnKeyListener(new Dialog.OnKeyListener() {            @Override            public boolean onKey(DialogInterface arg0, int keyCode,                    KeyEvent event) {                // TODO Auto-generated method stub                if (keyCode == KeyEvent.KEYCODE_BACK) {                    finish();                    dialog.dismiss();                }                return true;            }        });

Sounds like you want to set the OnCancelListener when you create the Dialog. It looks like this:

dialog.setOnCancelListener(new DialogInterface.OnCancelListener() {             @Override    public void onCancel(DialogInterface dialog) {        //do whatever you want the back key to do    }});

You need to override OnCancel method. This method calls on Back Key press. Here's code which works perfect to me.

 AlertDialog alertDialog;    alertDialog.setOnCancelListener(new OnCancelListener()     {                              @Override            public void onCancel(DialogInterface dialog)              {               // TODO Auto-generated method stub                    dialog.dismiss();                                       }}); 

Hope this will help you, and accept it if it is helpful to you.

Thanks..
