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​​组件接收此信息,但只能通过Context.registerReceiver()明确注册它.

您的Receiver(内部)课程：

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方法中注册它：

registerReceiver(mDateReceiver,new IntentFilter(Intent.ACTION_TIME_TICK));

并且不要忘记在onPause方法中取消注册：

unregisterReceiver(mDateReceiver);
