Date picker

<DatePicker

    android:id="@+id/datePicker"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"/>

```

In your Java or Kotlin code, you can interact with the `DatePicker`:

```java

public class YourActivity extends AppCompatActivity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.your_layout);

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

        // You can set an initial date if needed

        // datePicker.init(year, month, dayOfMonth, null);

        datePicker.setOnDateChangedListener(new DatePicker.OnDateChangedListener() {

            @Override

            public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

                // Handle the selected date

                String selectedDate = dayOfMonth + "/" + (monthOfYear + 1) + "/" + year;

                // Do something with the selected date

            }

        });

    }

}

```

In this example, the `DatePicker.OnDateChangedListener` is used to listen for changes in the selected date. The `onDateChanged` method is called when the user selects a new date. You can customize the code inside this method to perform actions based on the selected date.

Remember to replace `"your_layout"` with the actual name of your layout XML file.
