RecyclerView以宽度水平滚动

标签: android android-recyclerview scrollview

我有更多的项目在cardView中水平显示在recyclerView内,我有更多的卡片。

我尝试将cardView放在Horizo​​ntalScrollView中,它可以滚动个人卡片。我想滚动整个RecyclerView以滚动查看右端项目。

我尝试使用Horizo​​ntalScroolView内的RecyclerView无效。 NestedScrollView内的RecyclerView无效。

RecyclerView是一个片段。在viewPager tabLayout中,这是一个片段

片段xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   android:orientation="vertical"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:orientation="horizontal">    
  <android.support.v7.widget.RecyclerView
    android:id="@+id/record_recycler"
    android:layout_width="550dp"
    android:scrollbars="horizontal"
    android:layout_height="0dp"
    android:layout_weight="1" />
</LinearLayout>

适配器:

public class TestAdapter extends RecyclerView.Adapter{
   private List<Model> items;
   Context context;
   public TestAdapter(Context con, List<Model> itemslist) {
      context=con;
      this.items = itemslist;
    }

@Override
public int getItemViewType(int position) {
    return items.get(position).getUnique();
}

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
   if(viewType==0)
    return new MyViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.cricketrank_record_valuecard, parent, false));
else
    return new MyViewHolder1(LayoutInflater.from(parent.getContext()).inflate(R.layout.cricketrank_record_titlecard, parent, false));

}

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
  if (holder instanceof MyViewHolder)
    try{
    ((MyViewHolder)holder).bindViewHolder(position);
    }catch (Exception e){
        Log.e(Constant.Tag,e.toString());
    }
else if(holder instanceof MyViewHolder1)
    try{
        ((MyViewHolder1)holder).bindViewHolder(position);
    }catch (Exception e){
        Log.e(Constant.Tag,e.toString());
    }
}

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

public class MyViewHolder extends RecyclerView.ViewHolder{
    public TextView text,text1,text2,text3,text4,text5;
    public View mCardView;

   public MyViewHolder(View view) {
    super(view);
    text1 = (TextView) view.findViewById(R.id.text1);
    text2 = (TextView) view.findViewById(R.id.text2);
    text3 = (TextView) view.findViewById(R.id.text3);
    text4 = (TextView) view.findViewById(R.id.text4);
  }

 public void bindViewHolder(int position) {

    text1.setText(items.get(position).getTeam());
    text2.setText(items.get(position).getRank());
    text3.setText(items.get(position).getMatches());
    text4.setText(items.get(position).getPoints());
 }
 }
}

public class MyViewHolder1 extends RecyclerView.ViewHolder{
    public TextView text,text1,text2,text3,text4,text5;
    public RelativeLayout rl;

   public MyViewHolder1(View view) {
    super(view);
    text = (TextView) view.findViewById(R.id.text);
    text1 = (TextView) view.findViewById(R.id.text1);
    text2 = (TextView) view.findViewById(R.id.text2);
    text3 = (TextView) view.findViewById(R.id.text3);
    text4 = (TextView) view.findViewById(R.id.text4);
    rl = (RelativeLayout) view.findViewById(R.id.rl);
   }

  public void bindViewHolder(int position) {
    text1.setText(items.get(position).getTeam());
    text2.setText(items.get(position).getRank());
    text3.setText(items.get(position).getMatches());
    text4.setText(items.get(position).getPoints());

   }
 }
}

MainActivity:

RecyclerView record_recycler= (RecyclerView) view.findViewById(R.id.record_recycler);
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getActivity());
record_recycler.setLayoutManager(mLayoutManager);
record_recycler.setItemAnimator(new DefaultItemAnimator());
TestAdapter adapter = new TestAdapter(getActivity(), list);
record_recycler.setAdapter(adapter);

你可以使用LayoutManager refrence存档它,带有3个参数,在你的情况下,稍微改一下MainActivity,它会看起来像这样:

RecyclerView.LayoutManager mLayoutManager
= new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false);

就像文档说的那样,第二个参数定义了方向:

/**
 * @param context       Current context, will be used to access resources.
 * @param orientation   Layout orientation. Should be {@link #HORIZONTAL} or {@link
 *                      #VERTICAL}.
 * @param reverseLayout When set to true, layouts from end to start.
 */

我认为您正试图向两个方向滚动Recyclerview。垂直是recylerview的常用滚动,横向是滚动视图,如果它不符合上述宽度。正确?

如果你正在尝试这个,那么我认为不可能像你想象的那样滚动。 您可以在两个方向上滚动回收者视图,并持有不同的视图。

正如您所说,可以滚动cardview,默认情况下它不会正常滚动。因此,如果用户没有完全看到,则会滚动显示卡片内容,并将滚动视图设置为滚动。

可能的方法是,使用字段名称和值垂直保留视图。如果要创建更多内容,请再添加一行以适应值。

看看下面的内容:
