从BroadcastReceiver取消注册PhoneStateListener

Question

I am monitoring phone state through broadcast receiver, and for that I register a PhoneStateListener in onReceive of the receiver. Now if user wants to disable this feature, I disable the broadcast receiver, but the listener keeps running, and i am notified of the phone state. How can I unregister the PhoneStateListener registered in the broadcast receiver?

Answer 1

As the documentation says:

To unregister a listener, pass the listener object and set the events argument to LISTEN_NONE (0).

For example:

    telephonyManager.listen(myListener, PhoneStateListener.LISTEN_NONE);
