在这段代码中,我遇到了一个问题,我不确定如何为setRecurringAlarm()设置上下文。在这个代码示例中,我将 ,但我不确定这是否正确。

public class AlarmReceiver extends BroadcastReceiver {

private static final int INTERVAL = 15*1000; // check every 15 seconds

    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction() != null) {
            if (intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
                Log.v(TAG, "BroadcastReceiver - Received Boot Completed; Set Alarm");

                setRecurringAlarm(this);
            }else{
                Log.v(TAG, "BroadcastReceiver - Received " + intent.getAction());
            }
        }else{
            Log.v(TAG, "BroadcastReceiver - Received AlarmService");
        }
    }

    private void setRecurringAlarm(Context context) {
        Intent receiver = new Intent(context, AlarmReceiver.class);
        PendingIntent recurringDownload = PendingIntent.getBroadcast(context, 0, receiver, PendingIntent.FLAG_CANCEL_CURRENT);
        AlarmManager alarms = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
        alarms.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), INTERVAL, recurringDownload);
    }
}

您已在onReceive(Context context, Intent intent)中获得上下文,请使用它。
