先发送广播

//创建本地广播管理器对象

LocalBroadcastManager broadcastManager = LocalBroadcastManager.getInstance(getActivity());

                Intent intent = new Intent();

                intent.setAction("com.fragment.receiver.title");

                intent.putExtra("title", "发送广播");

//发送广播

                broadcastManager.sendBroadcast(intent);

注册接收本地广播  注意：设置的包名必须和过滤器的包名一致

LocalBroadcastManager.getInstance(getContext())

//注册接收本地广播        registerReceiver  注册接收

                .registerReceiver(new MyReceiveBroadcast(),new IntentFilter("com.fragment.receiver.title"));

创建一个普通类(或者是内部类)用来接收广播的信息

//重写接收广播的方法

@Override

    public void onReceive(Context context, Intent intent) {

        Log.i("hjp", "onReceive: ========"+intent.getStringExtra("title"));

        Toast.makeText(context, intent.getStringExtra("title"), Toast.LENGTH_SHORT).show();

    }
