启动Android闹钟启动

Question

我想在一周的特定一天发送通知，我的代码在当天工作，但每次打开智能手机/模拟器时都会收到通知。我该如何解决这个问题？

我的清单

<receiver android:name=".AutoStart"> 
      <intent-filter> 
       <action android:name="android.intent.action.BOOT_COMPLETED"></action> 
      </intent-filter> 
     </receiver> 
     <receiver android:name=".Alarm"></receiver> 
     <receiver android:name=".NotificationActivity"></receiver> 

AutoStart.java

public class AutoStart extends BroadcastReceiver 
{ 
    Alarm alarm = new Alarm(); 
    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) 
     { 
      alarm.SetAlarm(context); 
     } 
    } 
} 

而且我Alarm.java

@SuppressLint("Wakelock") 
    public class Alarm extends BroadcastReceiver 
    {  
     static RSSFeed myRssFeed = null; 
     @Override 
     public void onReceive(Context context, Intent intent) 
     { 

      PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); 
      PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, ""); 
      wl.acquire(); 

      SetAlarm(context); 

      wl.release(); 
     } 

    public void SetAlarm(Context context) 
    { 
     AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
     Intent i = new Intent(context, NotificationActivity.class); 
     PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); 
     Calendar calendar = new GregorianCalendar(); 
     calendar.set(Calendar.DAY_OF_WEEK, 2); 
     calendar.set(Calendar.HOUR_OF_DAY, 9); 
     calendar.set(Calendar.MINUTE, 30); 
     calendar.set(Calendar.SECOND, 0); 
     am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pi); 
    } 

    public void CancelAlarm(Context context) 
    { 
     Intent intent = new Intent(context, Alarm.class); 
     PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent, 0); 
     AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); 
     alarmManager.cancel(sender); 
    } 
} 

谢谢

因为你已经宣布android.intent.action .BOOT清单中的_COMPLETED权限。这意味着只要您的设备或手机重新启动，它就会调用BroadcastReceiver。

请尝试以下操作。 这是工作代码。它每10分钟唤醒一次CPU，直到电话关闭。

加入的Manifest.xml：

...

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

...

<receiver android:process=":remote" android:name="Alarm"></receiver> 

... 代码：从

package YourPackage; 
import android.app.AlarmManager; 
import android.app.PendingIntent; 
import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 
import android.os.PowerManager; 
import android.widget.Toast; 

public class Alarm extends BroadcastReceiver 
{  
    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); 
     PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, ""); 
     wl.acquire(); 

     // Put here YOUR code. 
     Toast.makeText(context, "Alarm !!!!!!!!!!", Toast.LENGTH_LONG).show(); // For example 

     wl.release(); 
    } 

public void SetAlarm(Context context) 
{ 
    AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
    Intent i = new Intent(context, Alarm.class); 
    PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); 
    am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000 * 60 * 10, pi); // Millisec * Second * Minute 
} 

public void CancelAlarm(Context context) 
{ 
    Intent intent = new Intent(context, Alarm.class); 
    PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent, 0); 
    AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); 
    alarmManager.cancel(sender); 
} 
} 

设置警报服务：

package YourPackage; 
import android.app.Service; 
import android.content.Context; 
import android.content.Intent; 
import android.os.IBinder; 

public class YourService extends Service 
{ 
Alarm alarm = new Alarm(); 
public void onCreate() 
{ 
    super.onCreate();  
} 

public void onStart(Context context,Intent intent, int startId) 
{ 
    alarm.SetAlarm(context); 
} 

@Override 
public IBinder onBind(Intent intent) 
{ 
    return null; 
} 

}
