Android 點擊一個區域彈出選擇日期

安卓開發中，怎麼做到點擊一個區域，然後彈出選擇出生日期，麻煩大神寫的詳細點，包括.xml文件和 java文件。謝謝好心人！

最佳回答：

java文件
public class DialogTest extends Activity {
private int mYear, mMonth, mDay;
TextView date;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.dialog);

    date = (TextView) findViewById(R.id.date);
    date.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            showDialog(0);
        }
    });
}

private final DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear,
            int dayOfMonth) {
        mYear = year;
        String mm;
        String dd;

        mMonth = monthOfYear + 1;
        mm = String.valueOf(mMonth);
        if (mm.length() < 2)
            mm = "0" + mm;

        mDay = dayOfMonth;
        dd = String.valueOf(mDay);
        if (dd.length() < 2)
            dd = "0" + dd;

        date.setText(String.valueOf(mYear) + "-" + mm + "-" + dd);
    }
};

@Override
protected Dialog onCreateDialog(int id) {
    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);

    switch (id) {
    case 0:
        return new DatePickerDialog(this, mDateSetListener, mYear, mMonth,
                mDay);
    }
    return null;
}

}

xml文件
<?xml version="1.0" encoding="utf-8"?>
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<TextView
    android:id="@+id/date"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" 
    android:text="點我"/>

之前用過的一個，用xml布局datepicker更方便，多看看書，都有介紹
