I need to check if my registered receiver is still registered if not how do i check it any methods?

推荐答案

我不知道直接通过API提供了一个API，如果你考虑的此线程：

I am not sure the API provides directly an API, if you consider this thread:

我想知道同样的事情。结果
  在我来说，我有一个调用广播接收器实施
  上下文＃unregisterReceiver（广播接收器）传递本身处理它接收的意图后，ARG。结果
  有一个小的机会，接收机的的onReceive（上下文，意图）方法被调用
  不止一次，因为它与多个注册 IntentFilters ，从而为潜在的抛出：IllegalArgumentException 从<$ C被抛出$ C>上下文＃unregisterReceiver（广播接收器）。

I was wondering the same thing.
In my case I have a BroadcastReceiver implementation that calls Context#unregisterReceiver(BroadcastReceiver) passing itself as the arg after handling the Intent that it receives.
There is a small chance that the receiver's onReceive(Context, Intent) method is called more than once, since it is registered with multiple IntentFilters, creating the potential for an IllegalArgumentException being thrown from Context#unregisterReceiver(BroadcastReceiver).

在我来说，我可以存储一个私人同步调用成员环境＃unregisterReceiver（广播接收器）前检查，但它会
  如果API提供的检查方法更清洁。

In my case I can store a private synchronized member to check before calling Context#unregisterReceiver(BroadcastReceiver), but it would be much cleaner if the API provided a check method.
