重新启动后，警报管理器不再重复

本文介绍了重新启动后，警报管理器不再重复的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我的警报管理器有问题。我创建了警报管理器，每15秒重复显示一次吐司。

I have problem with Alarm Manager. I create alarm manager which repeat displaying toast every 15 seconds.

重新启动设备后，吐司可见，但只有一次。即使重新启动后，我也想每15秒重复一次。

After rebooting my device, toast is visible, but only once. I want to repeat it again every 15 seconds even after reboot.

我可以添加些什么来解决此问题？

What can I add to solve this? Is this possible?

这是我的代码（AlarmReceiver类扩展了BroadcastReceiver）：

Here is my code (class AlarmReceiver 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, "YOUR TAG"); //Acquire the lock wl.acquire(); Toast.makeText(context, "wow", Toast.LENGTH_LONG).show(); //Release the lock wl.release(); } public void SetAlarm(Context context) { AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); Intent intent = new Intent(context, AlarmReceiver.class); PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent, 0); am.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 15000, pi); }

还有我的AndroidManifest.xml

And my AndroidManifest.xml

<receiver android:name=".view.activity.AlarmReceiver" android:enabled="true" android:exported="false" android:permission="android.permission.RECEIVE_BOOT_COMPLETED"> <intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> <action android:name="android.intent.action.QUICKBOOT_POWERON" /> </intent-filter> </receiver>

编辑：此问题的解决方法是在onReceiver（）中编辑代码：

The solve of this problem is edit code in onReceiver():

@Override public void onReceive(Context context, Intent intent) { if(intent.getAction()==null){ Toast.makeText(context, "lol", Toast.LENGTH_LONG).show(); } else { AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); Intent intent1 = new Intent(context, AlarmReceiver.class); PendingIntent pi = PendingIntent.getBroadcast(context, 0, intent1, 0); am.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 15000, pi); } }

推荐答案

似乎您只需要在onReceive方法中调用SetAlarm函数，并在清单中侦听已发送的事件。

It seems like you simply need to call your SetAlarm function in the onReceive Method, and listen for the sent event in your manifest.

在清单中

<intent-filter> <action android:name="android.intent.action.BOOT_COMPLETED" /> <action android:name="android.intent.action.QUICKBOOT_POWERON" /> //New <action android:name="com.packagename.custombroadcast" /> </intent-filter>

您的意图

Intent intent = new Intent(); intent.setAction("com.packagename.custombroadcast"); //Use Context.sendBroadcast sendBroadcast(intent);
