[chetan dhumane]

Hello all ,

why i get an error when i try to show dialog box after adding an OnClickListener

  
 buttonOk.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                // Perform action on clicks
                showDialog(DATE_DIALOG_ID);   // It shows the date dialog
            }
        });
