水平动态回收视图。

回收器视图实现

RecyclerView musicList = findViewById(R.id.MusicList);

// RecyclerView musiclist = findViewById(R.id.MusicList1);
// RecyclerView musicLIST = findViewById(R.id.MusicList2);
LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, false);
musicList.setLayoutManager(layoutManager);

String[] names = {"RAP", "CH SHB", "Faheem", "Anum", "Shoaib", "Laiba", "Zoki", "Komal", "Sultan","Mansoob Gull"};
musicList.setAdapter(new ProgrammingAdapter(names));'

回收器视图的适配器类，其中有一个视图持有者用于持有该回收器的视图

public class ProgrammingAdapter 
     extendsRecyclerView.Adapter<ProgrammingAdapter.programmingViewHolder> {

private String[] data;

public ProgrammingAdapter(String[] data)
{
    this.data = data;
}

@Override
public programmingViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    View view = inflater.inflate(R.layout.list_item_layout, parent, false);

    return new programmingViewHolder(view);
}

@Override
public void onBindViewHolder(@NonNull programmingViewHolder holder, int position) {
    String title = data[position];
    holder.textV.setText(title);
}

@Override
public int getItemCount() {
    return data.length;
}

public class programmingViewHolder extends RecyclerView.ViewHolder{
    ImageView img;
    TextView textV;
    public programmingViewHolder(View itemView) {
        super(itemView);
        img =  itemView.findViewById(R.id.img);
        textV =  itemView.findViewById(R.id.textt);
    }
}

有没有更好的方法来实现这个现在与RecyclerView现在?

Yes.

当您使用RecyclerView时，您需要指定一个LayoutManager，该LayoutManager负责布局视图中的每个项。LinearLayoutManager允许你指定一个方向，就像一个正常的LinearLayout一样。

要用RecyclerView创建一个水平列表，你可以这样做:

LinearLayoutManager layoutManager
    = new LinearLayoutManager(requireContext(), LinearLayoutManager.HORIZONTAL, false);

RecyclerView myList = (RecyclerView) findViewById(R.id.my_recycler_view);
myList.setLayoutManager(layoutManager);

随着RecyclerView库的发布，现在您可以轻松地对齐与文本绑定的图像列表。您可以使用LinearLayoutManager来指定您想要定位列表的方向，可以是垂直的，也可以是水平的，如下所示。

你可以从这篇文章中下载一个完整的工作演示。

您可以从布局文件或java/kotlin文件中定义方向和layoutManager

使用XML

<androidx.recyclerview.widget.RecyclerView
        android:id="@+id/my_recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal"
        app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager" />

在Java中

LinearLayoutManager layoutManager
= new LinearLayoutManager(requireContext(), LinearLayoutManager.HORIZONTAL, false);

RecyclerView rv= (RecyclerView) findViewById(R.id.my_recyclerView);
rv.setLayoutManager(layoutManager);

在Kotlin

val layoutManager
= LinearLayoutManager(requireContext(), LinearLayoutManager.HORIZONTAL, false)
my_recyclerView.layoutManager = layoutManager

试试这个:

myrecyclerview.setLayoutManager(
        new LinearLayoutManager(getActivity(),
                                LinearLayoutManager.HORIZONTAL,false));
myrecyclerview.setAdapter(recyclerAdapter);

只是以防你有一个带有碎片的回收视图。

水平方向和垂直方向都适用。

RecyclerView recyclerView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_test_recycler);
    recyclerView = (RecyclerView)findViewById(R.id.recyclerViewId);

    RecyclAdapter adapter = new RecyclAdapter();

    //Vertical RecyclerView
    RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
    recyclerView.setLayoutManager(mLayoutManager);

    //Horizontal RecyclerView
    //recyclerView.setLayoutManager(new LinearLayoutManager(getApplicationContext(),LinearLayoutManager.HORIZONTAL,false));

    recyclerView.setAdapter(adapter);

}
