凡注册一个BroadcastReceiver（活动周期的乐趣） [英] Where to register a BroadcastReceiver (Activity lifecycle fun)

问题描述

在哪里注册/在活动注销意图接收正确的地方？通常我会把这样的东西在这里：

Where's the right place to register/unregister an intent receiver in an Activity? Usually I would put stuff like this here:

class MyActivity 
{
    private BroadcastReceiver mMyReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.v(TAG, "Do something.");
        }
    };

    @Override
    public void onResume() {
        super.onResume();

        registerReceiver(mMyReceiver, new IntentFilter(...));
    }

    @Override
    public void onPause() {
        super.onPause();

        unregisterReceiver(mMyReceiver);
    }
}

问题是，我的活动就可以不再对广播如果它发生，而它在暂停状态作出反应。哪里是做这样的事情在正确的地方呢？

The problem is that my activity can then no longer respond to the broadcast if it happens while it's in the pause state. Where's the right place to do something like this then?

感谢

推荐答案

这应该在你的情况下工作：

This should work in your case:

Unregister in onDestroy().
