Android BroadcastReceiver在Fragment中的使用

BroadcastReceiver在activity中调用很简单，但是换成Fragment后

在Activity中操作BroadcastReceiver的方法在Fragment就不管用了

现项目需要在Fragment中设置BroadcastReceiver

然后发现不能注册广播了

查了一下资料，只要改动一下就能生效了

首先在Fragment中还是先建立BroadcastReceiver private BroadcastReceiver receiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { //这里写需要的业务逻辑 } }; 然后onCreateView()中创建 @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_battery, container, false); unBinder = ButterKnife.bind(this, view); //在此处加入意图以及注册BroadcastReceiver IntentFilter filter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED); getActivity().getApplicationContext().registerReceiver(receiver, filter); return view; } 最后别忘了把广播反注册了，在onDestroy()中 @Override public void onDestroy() { super.onDestroy(); getActivity().getApplicationContext().unregisterReceiver(receiver); }
