如何在Android上每天從早上8點運行服務到晚上8點

Question

我在Android上有服務。我想每天從早上8點到晚上8點運行這項服務。如何在Android應用程序中執行此操作。已啓動使用BroadcastReceiver BootUp事件的BootUp服務。如何執行此操作？

Answer 1

我已經試過如下的Alarm Manager。我想開始8上午......但它不是開始於8 AM..But所有吐司消息顯示應用程序...

AlarmReceiver.class

public class AlarmReceiver extends BroadcastReceiver { 

@Override 
public void onReceive(Context context, Intent intent) { 
    Toast.makeText(context, "Alarm Receiver", Toast.LENGTH_LONG).show(); 
    AlarmManager alarm=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
    Intent i = new Intent(context, MyService.class); 

    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, i, 0); 
    Calendar time = Calendar.getInstance(); 
    //time.setTimeInMillis(System.currentTimeMillis()); 
    time.add(Calendar.MINUTE, 8); 
    time.add(Calendar.HOUR, 0); 
    time.add(Calendar.SECOND, 0); 
    Toast.makeText(context, "App will start shortly", Toast.LENGTH_LONG).show(); 
    Toast.makeText(context, time.toString(), Toast.LENGTH_LONG).show(); 
    alarm.set(AlarmManager.RTC_WAKEUP, time.getTimeInMillis(), pendingIntent); 
} 
} 

manifest資源配置文件：

</application> 
<receiver android:name="AlarmReceiver"> 
      <intent-filter> 
       <action android:name="android.intent.action.BOOT_COMPLETED" /> 
      </intent-filter> 
     </receiver> 
</application> 
     <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> 
     <uses-permission android:name="android.permission.SET_TIME"/>

您需要使用AlarmManager類用於此目的。只需在您想要重複的鬧鐘中註冊您的活動/服務。並開始報警。
