我的Android进阶之旅------>Android DatePicker和TimePicker案例

简介

下面以一个让用户选择日期、时间的例子来示范DatePicker和TimePicker的功能和用法

step1:新建一个项目DateAndTimePicker

step2:编写应用的UI界面  /layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" android:layout_width="fill_parent"
	android:layout_height="fill_parent">
	<TextView android:layout_width="fill_parent"
		android:layout_height="wrap_content" android:text="选择购买此书的具体时间" />
	
	<DatePicker android:id="@+id/datePicker"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:layout_gravity="center_horizontal"/>
	
	<TimePicker android:id="@+id/timePicker"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:layout_gravity="center_horizontal"/>
	
	<EditText android:layout_width="fill_parent"
		android:layout_height="wrap_content" android:editable="false"
		android:cursorVisible="false"
		android:id="@+id/show" />
</LinearLayout>

step3:主程序MainActivity.java

package cn.roco.picker;

import java.util.Calendar;

import android.app.Activity;
import android.os.Bundle;
import android.widget.DatePicker;
import android.widget.DatePicker.OnDateChangedListener;
import android.widget.EditText;
import android.widget.TimePicker;
import android.widget.TimePicker.OnTimeChangedListener;

public class MainActivity extends Activity {

	private int year;
	private int month;
	private int day;
	private int hour;
	private int minute;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker);
		TimePicker timePicker = (TimePicker) findViewById(R.id.timePicker);

		Calendar calendar = Calendar.getInstance();
		year = calendar.get(Calendar.YEAR);
		month = calendar.get(Calendar.MONTH);
		day = calendar.get(Calendar.DAY_OF_MONTH);
		hour = calendar.get(Calendar.HOUR);
		minute = calendar.get(Calendar.MINUTE);

		datePicker.init(year, month, day, new OnDateChangedListener() {
			@Override
			public void onDateChanged(DatePicker view, int year, int month,
					int day) {
				MainActivity.this.year = year;
				MainActivity.this.month = month;
				MainActivity.this.day = day;
				// 显示时间
				showDate(year, month, day, hour, minute);
			}
		});

		timePicker.setOnTimeChangedListener(new OnTimeChangedListener() {
			@Override
			public void onTimeChanged(TimePicker view, int hour, int minute) {
				MainActivity.this.hour = hour;
				MainActivity.this.minute = minute;
				// 显示时间
				showDate(year, month, day, hour, minute);
			}
		});
	}

	private void showDate(int year, int month, int day, int hour, int minute) {
		EditText show = (EditText) findViewById(R.id.show);
		show.setText("您的购买日期为:" + year + "年" + month + "月" + day + "日 " + hour
				+ "时" + minute + "分 ");
	}

}

step4:部署应用到模拟器上，并选择日期和时间
