1.声明一个监听器，使用匿名内部类：
2.复写onCreateDialog(int id):
3.当你需要的时候调用showDialog方法：
代码如下：
package com.example.datepickerdialog1;
import android.os.Bundle;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.DatePicker;
public class MainActivity extends Activity
{
private static final int DATE_PICKER_ID=1;//静态常量
private Button showButton;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
showButton=(Button) findViewById(R.id.myButton);
showButton.setText("显示日历");
showButton.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View arg0)
{
//写1就行
showDialog(DATE_PICKER_ID);
}
});
}
//监听器，用户点下set后设置日期
DatePickerDialog.OnDateSetListener onDateSetListener=new DatePickerDialog.OnDateSetListener()
{
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth)
{
System.out.println(year+","+monthOfYear+","+dayOfMonth);
}
};
@Override
protected Dialog onCreateDialog(int id)
{
switch(id)
{
case DATE_PICKER_ID:
return new DatePickerDialog(this, onDateSetListener, 2013, 10, 18);
}
return null;
}
}
