步驟1 MainActivity.java

package com.example.alarmmanager; 

import com.example.alarmmanager.NotificationReceiverActivity; 
import com.example.alarmmanager.R; 

import android.os.Bundle; 
import android.app.Activity; 
import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.content.Context; 
import android.content.Intent; 
import android.view.Menu; 
import android.view.View; 
import android.widget.Toast; 

public class MainActivity extends Activity { 
private AlarmManagerBroadcastReceiver alarm; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    alarm = new AlarmManagerBroadcastReceiver(); 
} 
@Override 
protected void onStart() { 
super.onStart(); 
} 

    public void startRepeatingTimer(View view) { 
    Context context = this.getApplicationContext(); 
    if(alarm != null){ 
    alarm.SetAlarm(context); 
    }else{ 
    Toast.makeText(context, "Alarm is null", Toast.LENGTH_SHORT).show(); 
    } 
    } 

    public void cancelRepeatingTimer(View view){ 
    Context context = this.getApplicationContext(); 
    if(alarm != null){ 
    alarm.CancelAlarm(context); 
    }else{ 
    Toast.makeText(context, "Alarm is null", Toast.LENGTH_SHORT).show(); 
    } 
    } 

    public void onetimeTimer(View view){ 
    Context context = this.getApplicationContext(); 
    if(alarm != null){ 
    alarm.setOnetimeTimer(context); 
    createNotification(view); 
    }else{ 
    Toast.makeText(context, "Alarm is null", Toast.LENGTH_SHORT).show(); 
    } 
    } 
    public void createNotification(View view) { 
     /*********** Create notification ***********/ 

      final NotificationManager mgr= 
       (NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE); 
      Notification note=new Notification(R.drawable.ic_launcher, 
                  "Android Example Status message!", 
                  System.currentTimeMillis()); 

      // This pending intent will open after notification click 
      PendingIntent i= PendingIntent.getActivity(this, 0, 
                new Intent(this, NotificationReceiverActivity.class), 
                0); 

      note.setLatestEventInfo(this, "Android Example Notification Title", 
            "This is the android example notification message", i); 

      //After uncomment this line you will see number of notification arrived 
      //note.number=2; 
      mgr.notify(0, note); 

     } 
@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

} 

步驟2 AlarmManagerBroadcastReceiver.java

package com.example.alarmmanager; 

import java.text.Format; 
import java.text.SimpleDateFormat; 
import java.util.Date; 

import android.app.AlarmManager; 
import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.os.Bundle; 
import android.os.PowerManager; 
import android.view.View; 
import android.widget.Toast; 

public class AlarmManagerBroadcastReceiver extends BroadcastReceiver{ 
final public static String ONE_TIME = "onetime"; 
@Override 
public void onReceive(Context context, Intent intent) { 
    // TODO Auto-generated method stub 
    PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); 
    PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "YOUR TAG"); 
    //Acquire the lock 
    wl.acquire(); 

    //You can do the processing here update the widget/remote views. 
    Bundle extras = intent.getExtras(); 
    StringBuilder msgStr = new StringBuilder(); 

    if(extras != null && extras.getBoolean(ONE_TIME, Boolean.FALSE)){ 
    msgStr.append("One time Timer : "); 
    } 
    Format formatter = new SimpleDateFormat("hh:mm:ss a"); 
    msgStr.append(formatter.format(new Date())); 

    Toast.makeText(context, msgStr, Toast.LENGTH_LONG).show(); 

    //Release the lock 
    wl.release(); 
    Intent service1 = new Intent(context, NotificationService.class); 
    context.startService(service1); 
} 
public void SetAlarm(Context context) 
{ 
    AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
    Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class); 
    intent.putExtra(ONE_TIME, Boolean.FALSE); 
    PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0); 
    //After after 30 seconds 
    am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000 * 5 , pi); 
} 

public void CancelAlarm(Context context) 
{ 
    Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class); 
    PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent, 0); 
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); 
    alarmManager.cancel(sender); 
} 
public void setOnetimeTimer(Context context){ 
AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
    Intent intent = new Intent(context, AlarmManagerBroadcastReceiver.class); 
    intent.putExtra(ONE_TIME, Boolean.TRUE); 
    PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0); 
    am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), pi); 

} 

}

步驟3 NotificationReceiverActivity.java

package com.example.alarmmanager; 

import android.app.Activity; 
import android.os.Bundle; 

public class NotificationReceiverActivity extends Activity { 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.result); 
} 
} 

步驟4 NotificationService.java //這是推送通知，你可以刪除這個，如果你不希望通知

package com.example.alarmmanager; 
import android.app.Notification; 
import android.app.NotificationManager; 
import android.app.PendingIntent; 
import android.app.Service; 
import android.content.Context; 
import android.content.Intent; 
import android.os.IBinder; 
public class NotificationService extends Service { 
@Override 
public IBinder onBind(Intent intent) { 
    // TODO Auto-generated method stub 
    return null; 
} 

@Override 
public void onCreate() 
{ 
    // TODO Auto-generated method stub 
    super.onCreate(); 
} 

@Override 
public void onStart(Intent intent, int startId) 
{ 
    final NotificationManager mgr= 
      (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE); 
     Notification note=new Notification(R.drawable.ic_launcher, 
                 "Android Example Status message!", 
                 System.currentTimeMillis()); 

     // This pending intent will open after notification click 
     PendingIntent i= PendingIntent.getActivity(this, 0, 
               new Intent(this, NotificationReceiverActivity.class), 
               0); 

     note.setLatestEventInfo(this, "Android Example Notification Title", 
           "This is the android example notification message", i); 

     //After uncomment this line you will see number of notification arrived 
     note.number=startId; 
     mgr.notify(0, note); 
} 

@Override 
public void onDestroy() 
{ 
    // TODO Auto-generated method stub 
    super.onDestroy(); 
} 
} 

第5步：AndroidManifest.xml中

<uses-permission android:name='android.permission.WAKE_LOCK'/> 

<receiver android:name="com.example.alarmmanager.AlarmManagerBroadcastReceiver"> </receiver> 
    <service android:name="com.example.alarmmanager.NotificationService" 
      android:enabled="true" /> 

步驟6 activity_main.xml中

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context=".MainActivity" > 

<TextView 
    android:id="@+id/textView1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="@string/hello_world" /> 

<Button 
    android:id="@+id/button1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/textView1" 
    android:layout_centerHorizontal="true" 
    android:layout_marginTop="43dp" 
    android:onClick="startRepeatingTimer" 
    android:text="Start Alarm repeating 30 sec" /> 

<Button 
    android:id="@+id/button2" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/button1" 
    android:layout_marginTop="50dp" 
    android:layout_toRightOf="@+id/textView1" 
    android:onClick="cancelRepeatingTimer" 
    android:text="Cancel Alarm" /> 

<Button 
    android:id="@+id/button3" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/button2" 
    android:layout_centerHorizontal="true" 
    android:layout_marginTop="58dp" 
    android:onClick="onetimeTimer" 
    android:text="Start One Time Alarm" /> 

</RelativeLayout> 

步驟7爲result.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" > 
<TextView android:text="This is the result activity opened from the notification" 
    android:layout_width="wrap_content" android:layout_height="wrap_content" 
    android:id="@+id/textView1"></TextView> 

</RelativeLayout>
