Android 日期和时间选择器

1. 日期选择器 ： 

Calendar calendar = Calendar.getInstance();
new DatePickerDialog(DialogSample.this,  
                 new DatePickerDialog.OnDateSetListener() {  
                     @Override  
                     public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {  
                         String info = "您选择的日期是：";  
                         info += year + "年" + monthOfYear + "月" + dayOfMonth + "日";  
                         //dateText.setText(info);  
                         Toast.makeText(DialogSample.this, info, Toast.LENGTH_LONG).show();
                     }  
                 }, calendar.get(Calendar.YEAR),  
                 calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH)).show(); 

2. 时间选择器 ： 

Calendar calendar = Calendar.getInstance();
new TimePickerDialog(DialogSample.this,
                        new TimePickerDialog.OnTimeSetListener() {
                            @Override
                            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                                String timeInfo = "您选择的时间是：";
                                timeInfo += hourOfDay+ "时" + minute + "分";
                                Toast.makeText(DialogSample.this, timeInfo, Toast.LENGTH_LONG).show();
                            }
                        },calendar.get(Calendar.HOUR_OF_DAY),calendar.get(Calendar.MINUTE),true).show();

使用示例 ： 

package net.simonvt.datepicker.samples;

import java.util.Calendar;

import android.app.Activity;
import android.app.TimePickerDialog;
import android.os.Bundle;
import android.view.View;
import android.widget.TimePicker;
import android.widget.Toast;


public class DialogSample extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_dialog);

        findViewById(R.id.btnDialog).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
            /*final DatePickDialog dp = new DatePickDialog(DialogSample.this, "日期选择", "确定", "取消");
            dp.show();*/
            Calendar calendar = Calendar.getInstance();
            /*
             new DatePickerDialog(DialogSample.this,  
                 new DatePickerDialog.OnDateSetListener() {  
                     @Override  
                     public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {  
                         String info = "您选择的日期是：";  
                         info += year + "年" + monthOfYear + "月" + dayOfMonth + "日";  
                         //dateText.setText(info);  
                         Toast.makeText(DialogSample.this, info, Toast.LENGTH_LONG).show();
                     }  
                 }, calendar.get(Calendar.YEAR),  
                 calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH)).show();  */
            new TimePickerDialog(DialogSample.this,
                        new TimePickerDialog.OnTimeSetListener() {
                            @Override
                            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                                String timeInfo = "您选择的时间是：";
                                timeInfo += hourOfDay+ "时" + minute + "分";
                                Toast.makeText(DialogSample.this, timeInfo, Toast.LENGTH_LONG).show();
                            }
                        },calendar.get(Calendar.HOUR_OF_DAY),calendar.get(Calendar.MINUTE),true).show();
            }
        });

    }
