DatePicker 日期选择对话框的实现

package dateandtimer;

import java.util.Calendar;
import java.util.Date;
import java.util.Locale;

import com.example.ctroltest.R;

import android.os.Bundle;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;

public class DatePickerTest extends Activity {
 private TextView datedisp;
 private Button dateselectbtn;
 private int myear,mmonth,mday;
private DatePickerDialog.OnDateSetListener dateListener=new DatePickerDialog.OnDateSetListener() {
  
  @Override
  public void onDateSet(DatePicker view, int year, int monthOfYear,
    int dayOfMonth) {
   // TODO Auto-generated method stub
   datedisp.setText("你选择了"+year+"年"+(monthOfYear+1) +"月"+dayOfMonth+"日");
   
  }
 };
 

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.date_picker_test);
  datedisp=(TextView)findViewById(R.id.datedisp);
  dateselectbtn=(Button)findViewById(R.id.dateselectbtn);
  Calendar myCalendar=Calendar.getInstance(Locale.CHINA);
  Date mydate=new Date();
  myCalendar.setTime(mydate);
  myear=myCalendar.get(Calendar.YEAR);
  mmonth=myCalendar.get(Calendar.MONTH);
  mday=myCalendar.get(Calendar.DAY_OF_MONTH);  
  dateselectbtn.setOnClickListener(new OnClickListener() {
   
   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    DatePickerDialog datePickerDialog=
      new DatePickerDialog(DatePickerTest.this,dateListener, myear,mmonth, mday); 
    datePickerDialog.show();
   }
  });
  
  
  
 }
 

 
 

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.date_picker_test, menu);
  return true;
 }

}

 

布局文件：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="日期为:" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/datedisp"
        />
    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="选择日期"
        android:id="@+id/dateselectbtn"
 
        />
    </LinearLayout>

</LinearLayout>

 

最后的效果：
