App crashes instead of Date Picker dialog popping up

I want the date picker dialog to pop up when an EditText is clicked. I have followed a few SO posts and tutorials but nothing pops up and then the app crashes after a while.

I am not sure if this is the right way to do it or if I am missing something. Any help is appreciated!

My code so far, Activity.java onCreate:

inputDate = (EditText) findViewById(R.id.inputDate);
calendar = Calendar.getInstance();

final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, monthOfYear);
calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
updateLabel();
}

};

inputDate.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
new DatePickerDialog(getApplicationContext(), date, calendar
.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
calendar.get(Calendar.DAY_OF_MONTH)).show();
}
});


updateLabel:

private void updateLabel() {

String myFormat = "MM/dd/yy"; //In which you need put here
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);

inputDate.setText(sdf.format(calendar.getTime()));
}


xml:

<EditText
android:id="@+id/inputDate"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="mm / dd/ yyyy"
android:imeOptions="actionDone"
android:focusable="false"
/>

Answer

Thats mine and it works well:

DatePickerDialogdatePickerDialog = new DatePickerDialog(this, R.style.DialogTheme, new DatePickerDialog.OnDateSetListener() {
   @Override
   public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
      //Magic happens here
   }
}, nowYear, nowMonth, nowDay);
datePickerDialog.show();
