下述程式主要學習 TimePicker 的用法，不使用 Calendar 的做法同上一篇相同，需注意 24 小時時間置的問題。

1.MainActivity.java

package com.sweetlover.activity;import com.sweetlover.timepickerdemo.R;import android.app.Activity;import android.os.Bundle;import android.widget.TextView;import android.widget.TimePicker;import android.widget.TimePicker.OnTimeChangedListener;public class MainActivity extends Activity {private TextView textView = null;private TimePicker timePicker = null;private int curHour = 8, curMinute = 30;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.activity_main);textView = (TextView)findViewById(R.id.textView1);timePicker = (TimePicker)findViewById(R.id.timePicker1);timePicker.setIs24HourView(false);timePicker.setOnTimeChangedListener(new TimeChangedListener());}private class TimeChangedListener implements OnTimeChangedListener {@Overridepublic void onTimeChanged(TimePicker view, int hourOfDay, int minute) {// TODO Auto-generated method stubcurHour = hourOfDay;curMinute = minute;textView.setText("目前時間：" + curHour + " 時 " + curMinute + " 分");}}}

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" >    <TimePicker        android:id="@+id/timePicker1"        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <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.timepickerdemo"    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>
