You use the DatePicker control to select a date.

Example

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">

    <TextView
        android:id="@+id/dateDefault"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" />

    <DatePicker
        android:id="@+id/datePicker"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

The following code sets the DatePicker with Date.

/*ww  w.j a  va 2 s. c o  m*/
package com.java2s.app;

import android.app.Activity;
import android.os.Bundle;
import android.widget.DatePicker;
import android.widget.TextView;

public class MainActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        TextView dateDefault = (TextView) findViewById(R.id.dateDefault);

        DatePicker dp = (DatePicker) this.findViewById(R.id.datePicker);
        // subtract 1 from December (12) to set it to December
        dp.init(2008, 11, 10, null);
        // The month, and just the month, is zero-based.
        dateDefault.setText("Date defaulted to " + (dp.getMonth() + 1) + "/" +
                dp.getDayOfMonth() + "/" + dp.getYear());

    }
}

Note

For the month, the internal value is zero-based, which means that January is 0 and December is 11.

If you do not set values for these controls, the default values will be the current date and time as known to the device.
