下述程序主要學習 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;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.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 {

		@Override
		public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
			// TODO Auto-generated method stub
			curHour = hourOfDay;
			curMinute = minute;
			textView.setText("當前時間：" + curHour + " 時 " + curMinute + " 分");
		}
	}
}

<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">

</textview></timepicker></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">

            </category></action></intent-filter>
        </activity>
    </application>

</uses-sdk></manifest>
