DatePicker 示例

下述程序主要学习 DatePicker 和 Calendar 的使用方法，需注意 Eclipse 似乎不能显示 DatePicker 的预览，但可以正常工作的，这一点已查阅 StackOverflow。

1.MainActivity.java

package com.sweetlover.activity;import com.sweetlover.datepickerdemo.R;import android.app.Activity;import android.os.Bundle;import android.widget.DatePicker;import android.widget.DatePicker.OnDateChangedListener;import android.widget.TextView;public class MainActivity extends Activity {private TextView textView = null;//private Calendar calendar = null;// 不使用 Calendar 是因为它会显示出来，和 DatePicker 冲突private DatePicker datePicker = null;private int curYear, curMonth, curDay;private class DateChangedListener implements OnDateChangedListener {@Overridepublic void onDateChanged(DatePicker view, int year, int monthOfYear,int dayOfMonth) {// TODO Auto-generated method stubcurYear = year;curMonth = monthOfYear;curDay = dayOfMonth;textView.setText("当前时间：" + curYear + "年" + curMonth + "月" + curDay + "日");}}@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.activity_main);textView = (TextView)findViewById(R.id.textView1);datePicker = (DatePicker)findViewById(R.id.datePicker1);curYear = 2016;curMonth = 1;curDay = 19;//calendar = Calendar.getInstance();//curYear = calendar.get(Calendar.YEAR);//curMonth = calendar.get(Calendar.MONTH) + 1;//curDay = calendar.get(Calendar.DAY_OF_MONTH);textView.setText("当前时间：" + curYear + "年" + curMonth + "月" + curDay + "日");datePicker.init(curYear, curMonth, curDay, new DateChangedListener());}}

2.activity_main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:padding="30dp"    android:orientation="vertical" >    <DatePicker        android:id="@+id/datePicker1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center" />    <TextView        android:id="@+id/textView1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center"        android:layout_marginTop="30dp"        android:textAppearance="?android:attr/textAppearanceMedium" /></LinearLayout>

3.AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.sweetlover.datepickerdemo"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk        android:minSdkVersion="8"        android:targetSdkVersion="19" />    <application        android:allowBackup="true"        android:icon="@drawable/ic_launcher"        android:label="@string/app_name"        android:theme="@style/AppTheme" >        <activity android:name="com.sweetlover.activity.MainActivity">            <intent-filter>                <action android:name="android.intent.action.MAIN"/>                <category android:name="android.intent.category.LAUNCHER"/>            </intent-filter>        </activity>    </application></manifest>
