问题描述
我的任务是每次更改日期（每隔12点）触发一个方法来刷新或重置我的应用程序。我试图在网上搜索答案，但我找不到任何东西。我可以使用android中的任何方法/或监听器吗？或任何方法？
任何建议的人？
My task is to trigger a method to refresh or reset my application every time the date change (every 12am). I tried to search the web for an answer but I can't find anything. Is there any method/or listeners in android that I can use? or any approach?Any suggestion guys?
推荐答案
是的，您可以在Android上收听日期/时间更改。为此，请在您的中明确注册以下意向过滤器活动：
Yes you can listen to date / time changes on Android. For this, register a BroadcastReceiver for the following intent filters explicitly in your Activity:
android.intent.action.ACTION_TIME_TICK
此意图每分钟发送一次。您无法通过清单中声明的组件接收此内容，但只能通过。
This Intent is sent every minute. You can not receive this through components declared in your manifest, but only by explicitly registering for it with Context.registerReceiver().
您的Receiver（内部）类：
Your Receiver (inner) class:
private final MyDateChangeReceiver mDateReceiver = new MyDateChangeReceiver();
public class MyDateChangeReceiver extends BroadcastReceiver{
@Override
public void onReceive(final Context context, Intent intent) {
// compare current time and decide if it's 12 AM
Log.d("MyDateChangeReceiver", "Time changed");
}
}
在onResume方法中注册：
Register it in your onResume method:
registerReceiver(mDateReceiver, new IntentFilter(Intent.ACTION_TIME_TICK));
并且不要忘记在onPause方法中取消注册：
and do not forget to un-register it in your onPause method:
unregisterReceiver(mDateReceiver);
