How to set the value of the datePicker in to EditText?

Question

My XMl Layout is as like below:

<RelativeLayout  android:id="@+id/dateSelectionLayout"  android:layout_width="fill_parent" android:layout_height="wrap_content"
        android:orientation="vertical" android:visibility="visible">

            <EditText android:layout_height="wrap_content" android:layout_width="fill_parent" 
                android:singleLine="true" android:id="@+id/dateSelectionEditText" android:gravity="center"
                android:textColor="#000000" android:textSize="14sp" android:cursorVisible="false"
                android:focusable="false"
                android:hint="tax code" android:layout_weight="1"/>

            <DatePicker android:id="@+id/datePicker"
                android:layout_width="fill_parent" android:layout_height="wrap_content"
                android:layout_weight="1" android:layout_below="@+id/dateSelectionEditText"/>

    </RelativeLayout>

Now i want to change the value of the editText that is based on the datePicker date. If User change the date then it should be reflected on the editText at that time. how it is Possible ?

Edited: I have done like this: Have set the resourcec like:

datePicker = (DatePicker) findViewById(R.id.datePicker);
        dateSelectionEditText = (EditText)findViewById(R.id.dateSelectionEditText);

And have set the override method like this:

@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear,
        int dayOfMonth) {
    dateSelectionEditText.setText(dayOfMonth+"/"+monthOfYear+"/"+year);

}

But still not getting any value on the changing of date picker value.

Edited:

After Kasper Moerch's answer i got the solution. But there is little problem. I am using this code to init the datepicker.

final Calendar c = Calendar.getInstance();  
        //dateSelectionEditText.setText( "" + dayOfMonth + "-" + monthOfYear + "-" + year );
        datePicker.init(c.get(Calendar.YEAR), c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH), new MyOnDateChangedListener());
        Toast.makeText(getApplicationContext(), ""+position+"", Toast.LENGTH_SHORT).show();

Now with this, I am able to see the changed value from datePicker. But it takes 0 as a First month (from January) instead of the "1". So why it is happend like this ?

Thanks.

What you need to do is get a reference to the EditText and the DatePicker:

EditText editText = (EditText) findViewById( R.id.dateSelectionEditText );
DatePicker datePicker = (DatePicker) findViewById( R.id.datePicker );

Then you need to create an OnDateChangedListener:

private class MyOnDateChangedListener implements OnDateChangedListener {
  @Override
  public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
     editText.setText( "" + dayOfMonth + "-" + (monthOfYear + 1) + "-" + year );
  }
};

All thats left to do is just initialize the DatePicker:

datePicker.init( year, monthOfYear, dayOfMonth, new MyOnDateChangedListener() ).
