安卓-广播LocalBroadcastManager

温馨提示：
要保证发送消息和接受消息使用的是同一个Activity。

发送消息

        Intent intent = new Intent(BROADCAST_RECEIVER);
        intent.putExtra("x", 1);
        intent.putExtra("y", 1);
        LocalBroadcastManager.getInstance(getActivity()).sendBroadcast(intent);

接受消息

//注册
LocalBroadcastManager.getInstance(getActivity()).registerReceiver(mBroadcastReceiver, new IntentFilter(BROADCAST_RECEIVER));
 mBroadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                // 获取点击位置
                float x = intent.getFloatExtra("x", -1);
                float y = intent.getFloatExtra("y", -1);
                Rect fragmentBounds = new Rect();
                rootView.getGlobalVisibleRect(fragmentBounds);
                if(fragmentBounds.contains((int)x, (int)y)){
                    LOGGER.info("在范围内");
                }else{
                    LOGGER.info("在范围外");
                }
            }
        };
//LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(mBroadcastReceiver);
