RecyclerView Horizo​​ntal Scrollview example 如何创建水平recyclerview？水平滚动视图示例

Question

如何使用回收器视图为 Features 和 Rules 下的元素创建水平滚动？

我知道对于 属性 类型 和 房间数量 我可以使用两个单独的回收站视图。但是，我是否需要创建两个回收器视图来显示这些元素，因为文本元素的长度将不均匀，并且如果添加更多规则和功能，以满足不断扩展的项目列表？

Answer 1

You can create a horizontal scrollview by doing this ie set horizontal layout manager

recyclerViewTeams.setLayoutManager(new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false));

示例代码

 <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerViewProperty"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="10dp" />

在 Java class

 private RecyclerView recyclerViewProperty;


 recyclerViewProperty = (RecyclerView) view.findViewById(R.id.recyclerViewProperty);

recyclerViewTeams.setLayoutManager(new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false));

public class TeamsAdapter 扩展 RecyclerView.Adapter {

ArrayList<TeamsListingModal> arrayList;
private Activity mContext;
private int selected_position;
private boolean isSelected = false;

public class MyView extends RecyclerView.ViewHolder {

    public TextView textview;
    private RelativeLayout parentLayout;


    public MyView(View view) {
        super(view);
        parentLayout = (RelativeLayout) view.findViewById(R.id.parentLayout);
        textview = (TextView) view.findViewById(R.id.textview);

    }
}


    public TeamsAdapter(Activity activity, ArrayList<CustomModal> arrayList) {
        this.mContext = activity;
        this.arrayList = arrayList;

    }

    @Override
    public MyView onCreateViewHolder(ViewGroup parent, int viewType) {

        View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.property_adapter_item, parent, false);

        return new MyView(itemView);
    }

    @Override
    public void onBindViewHolder(final MyView holder, final int position) {
        //inflate views here

    }

    @Override
    public int getItemCount() {
        return arrayList.size();
    }

}

和xml这里property_adapter_item

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/parentLayout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="5dp">

    <TextView
        android:id="@+id/textView"
        android:layout_width="70dp"
        android:layout_height="70dp"
        app:border_width="5dp" />
</RelativeLayout>

Answer 2

LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false);
recyclerView.setLayoutManager(linearLayoutManager);

Answer 3

In Kotlin Horizontal Scroolview in RecyclerView: - We use this Code 
 recycler_upcoming.layoutManager =
            LinearLayoutManager(sContext, LinearLayoutManager.HORIZONTAL, false)
        recycler_upcoming.adapter =
            InboxUpcomingAdapter(list, sContext)

-> sContext mean Ur Context
-> If you pass false then scroll right to left
-> If You pass true then scroll left to right
