android系统自带的日期、时间对话框的用法

代码：

package com.test;

import java.util.Calendar;

import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.TimePickerDialog;
import android.os.Bundle;
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;
import android.widget.TimePicker;

public class MainActivity extends Activity {
private Button button;
TextView textView;
StringBuffer stringBuilder;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button=(Button)findViewById(R.id.button1);
        textView=(TextView)findViewById(R.id.textView1);
        button.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                Calendar c=Calendar.getInstance();

                Dialog dateDialog=new DatePickerDialog(MainActivity.this, new DatePickerDialog.OnDateSetListener() {

                    @Override
                    public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) {
                        // TODO Auto-generated method stub
                        stringBuilder=new StringBuffer("");
                        stringBuilder.append(arg1+"-"+(arg2+1)+"-"+arg3+" ");
                        Calendar time=Calendar.getInstance();
                        Dialog timeDialog=new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() {

                            @Override
                            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                                // TODO Auto-generated method stub
                                stringBuilder.append(hourOfDay+":"+minute);
                                textView.setText("您设置的时间为:"+stringBuilder);
                            }
                        }, time.get(Calendar.HOUR_OF_DAY), time.get(Calendar.MINUTE), true);
                        timeDialog.setTitle("请选择时间");
                        timeDialog.show();
                    }

                }, c.get(Calendar.YEAR), c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH));
                dateDialog.setTitle("请选择日期");
                dateDialog.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.main, menu);
        return true;
    }

}
