Fragement横竖屏切换

项目的Fragment比较简单，除了标题栏就一个网络数据显示的RecyclerView，Adapter Item layout对应了不同的xml文件，分别在layout_port（竖屏）、layout_land（横屏）、layout(默认)文件夹下。但切换时发现，Adapter Item layout并未发生变化。

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_gift_record, container, false);
        view.findViewById(R.id.btn_back).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                gotoExchangeGiftFragment();
            }
        });

        recyclerView = view.findViewById(R.id.record);
        final GiftRecordAdapter adapter = new GiftRecordAdapter();
        recyclerView.setAdapter(adapter);
        layoutManager = new LinearLayoutManager(getActivity());
        recyclerView.setLayoutManager(layoutManager);

        int mCurrentOrientation = getResources().getConfiguration().orientation;
        if ( mCurrentOrientation == Configuration.ORIENTATION_PORTRAIT ){
            layoutManager.setOrientation(OrientationHelper.VERTICAL);
        }else {
            layoutManager.setOrientation(OrientationHelper.HORIZONTAL);
        }

        TYGameSDKManager.getInstance().giftRecord(new Listener>() {
            @Override
            public void success(List res) {
                Log.d("test", "gift record success");
                adapter.setData(res);
            }

            @Override
            public void fail(String reason) {
                Log.d("test", "gift record fail");

            }
        });

        return view;
    }

因为切换时会回调onConfigurationChanged()函数，因此需要在此函数中设置方向、对页面进行重绘：

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        int mCurrentOrientation = newConfig.orientation;
        if ( mCurrentOrientation == Configuration.ORIENTATION_PORTRAIT ){
            layoutManager.setOrientation(OrientationHelper.VERTICAL);
        }else {
            layoutManager.setOrientation(OrientationHelper.HORIZONTAL);
        }
        recyclerView.removeAllViews();
        recyclerView.getAdapter().notifyDataSetChanged();

    }
