Datepicker Dialog Box Does Not Open On Click

When I run and click the button, it does not open the datapicker dialogbox. I am not able to find out what is incorrect. Please, any one can check and guide me where is the incorre

Solution 1:

@OverridepublicvoidonClick(View v) {
        switch (v.getId()) {
            case R.id.button_date:
                showDialog(999);// Method for Show Dialog. You can use any Intbreak;
            case R.id.button_time:
                  showDialog(99);
                break;
        }
    }

and Define this method for Identified dialog from int.

@Overrideprotected Dialog onCreateDialog(int id) {
    // TODO Auto-generated method stubif (id == 999) {
        return new DatePickerDialog(this, myDateListener, yr, month, day);
    } elseif (id == 99) {
        return new TimePickerDialog(this, myTimeListener, h, m, true);
    }
    returnnull;
}
