推荐答案

BroadcastReceievers被设计成只有当一些广播接收（系统广播或用户定义的广播）运行。如果您想运行一些code的每一分钟，你可以创建一个服务，并安排它使用报警管理器每分钟运行。您可以使用警报管理开始从您广播接收机的服务，它将运行的每一分钟。

BroadcastReceievers are designed to run only when some broadcast is received (System broadcast or user defined broadcast). In case you want to run some code every minute, you can create a service and schedule it for every minute run using an Alarm Manager. You can start the service from your broadcast receiver using alarm manager and it will run every minute.

在你的广播接收器，使用code的onRecieve（）方法类似如下：

In the onRecieve() method of your broadcast receiver, use code similar to the below given:

PendingIntent service = null; 
Intent intentForService = new Intent(context.getApplicationContext(), YourService.class);
final AlarmManager alarmManager = (AlarmManager) context
                .getSystemService(Context.ALARM_SERVICE);
final Calendar time = Calendar.getInstance();
time.set(Calendar.MINUTE, 0);
time.set(Calendar.SECOND, 0);
time.set(Calendar.MILLISECOND, 0);
if (service == null) {
 service = PendingIntent.getService(context, 0,
                    intentForService,    PendingIntent.FLAG_CANCEL_CURRENT);
        }

        alarmManager.setRepeating(AlarmManager.RTC, time.getTime()
                .getTime(), 60000, service);
