Question

I have been using RecycleView with an horizontalScrollView to create this(don't mind the blue ball)

发生的事情取决于标签的文字大小，之后的所有其他标签会在它们之间产生巨大差距，下面我留下了一张图片来向您展示正在发生的事情。

这里我有来自回收视图的xml文件。

<HorizontalScrollView
    android:id="@+id/searchNeighborhoodsHorizontalScroll"
    android:layout_width="wrap_content"
    android:layout_height="50dp"
    android:layout_below="@id/searchNeighborhoodsRelative"
    android:layout_marginTop="10dp"
    android:visibility="visible">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/searchNeighborhoodsTagView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:scrollbars="vertical"
        android:visibility="visible" />

</HorizontalScrollView>

以下是回收项目中的xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="35dp"
android:layout_marginLeft="5dp"
android:background="@drawable/tag_background">


<TextView
    android:id="@+id/tagText"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_marginLeft="20dp"
    android:text="Text test"
    android:textColor="#FFFFFF" />

<ImageButton
    android:id="@+id/tagDeleteButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_marginLeft="15dp"
    android:layout_marginRight="20dp"
    android:layout_toRightOf="@id/tagText"
    android:background="@android:color/transparent"
    android:src="@drawable/ic_tag_close" />

设置适配器

 GridLayoutManager manager = new GridLayoutManager(getActivity(), tagList.size(), GridLayoutManager.VERTICAL, false);
    RecyclerView tagView = (RecyclerView) v.findViewById(R.id.searchNeighborhoodsTagView);
    tagView.setLayoutManager(manager);
    tagView.setAdapter(adapter);

和适配器

public TagsAdapter(Context context, ArrayList<String> items) {
    this.context = context;
    this.items = items;

    inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = inflater.inflate(R.layout.tag_item, parent, false);

    return new ViewHolder(view);
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    holder.setupCard(items, position, context);
}

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


@Override
public long getItemId(int position) {
    return 0;
}


public static class ViewHolder extends RecyclerView.ViewHolder {

    private final TextView tagText;
    private final ImageButton tagDeleteButton;

    public ViewHolder(View itemView) {
        super(itemView);

        tagText = (TextView) itemView.findViewById(R.id.tagText);
        tagDeleteButton = (ImageButton) itemView.findViewById(R.id.tagDeleteButton);

        setFont();
    }

    private void setFont() {
        tagText.setTypeface(LarSingleton.exoMedium);
    }

    public void setupCard(ArrayList<String> items, int position, Context context) {
        tagText.setText(items.get(position).toString());
    }
}

你们对如何解决这个问题有任何想法吗？或者为什么会这样？

Answer 1

RecyclerView.LayoutManager layoutManager = new
            GridLayoutManager(getApplicationContext(), 2,GridLayoutManager.HORIZONTAL, false);

建议你可以在不使用水平滚动视图的情况下实现它，因为recyclerview有自己的滚动

每个项目具有不同宽度大小的RecycleView
