horizontalscrollview嵌套Gridview（换种思路recycleView轻松实现）

最近有用到horizantalsrcollview嵌套gridview，说实话，效果能实现，但bug挺多。

而且布局的宽度必须计算好，搞不好还会因为适配原因，各种不匹配真心纠结。

所以后来果断换了种方式。recycleview可以轻松实现这种功能。

布局文件xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ffffff"
    android:orientation="vertical">

    <View
        android:layout_width="match_parent"
        android:layout_height="1px"
        android:background="#E3E3E3" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="2dp">

        <ImageView
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:paddingBottom="8dp"
            android:paddingTop="8dp"
            android:src="@mipmap/red_rectangle" />

        <TextView
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="15"
            android:paddingBottom="8dp"
            android:paddingTop="8dp"
            android:text="为您推荐" />

    </LinearLayout>

    <View
        android:layout_width="match_parent"
        android:layout_height="1px"
        android:background="#E3E3E3" />

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rv_show"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        ></android.support.v7.widget.RecyclerView>

</LinearLayout>

Mainactivity中：

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home);

//1.获取recycleview

recyclerView = (RecyclerView) findViewById(R.id.rv_show);

//2.载入数据

initRvBeans();

//3.设置适配器

myRvAdapter = new MyRvAdapter(getContext(), gridBeans);
recyclerView.setAdapter(myRvAdapter);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity(),
        LinearLayoutManager.HORIZONTAL, false));

}

public void initRvBeans() {
    DataRequest.getjsonData(getActivity(), s_recommondProduct, params, new DataRequest.CallBackData() {
        @Override
        public void success(String result) {
            try {
                JSONObject dataObject = new JSONObject(result);
                JSONArray dataArray = dataObject.getJSONArray("Goods");
                for (int i = 0; i < dataArray.length(); i++) {
                    JSONObject object = dataArray.getJSONObject(i);
                    int goodsBuyNumber = object.getInt("goodsBuyNumber");
                    String goodsImagePath = object.getString("goodsImagePath");
                    int goodsLimitNumber = object.getInt("goodsLimitNumber");
                    String goodsName = object.getString("goodsName");
                    int special = object.getInt("special");
                    db_Bean = new Db_Bean(goodsBuyNumber, goodsImagePath, goodsLimitNumber, goodsName, special);
                    gridBeans.add(db_Bean);
                    myRvAdapter.notifyDataSetChanged();
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        @Override
        public void fail(String result) {

        }
    });

IT是个大舞台，要学的东西还很多，要走的路还很长。

慢慢来不一定是要求自己放松，更多的是持之以恒的努力。

写下这些一来是记录自己走的一些弯路，也是留待以后自己能经常回过头来看看自己经历的那些，走过的那些路
