我正在开发一个需要水平滚动条中的图像和文本组的应用程序。我尝试了几件事，但我无法得到这个，任何人都可以指导我与这些人。

这是我所做的，

主要的.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
   <HorizontalScrollView 
   android:id="@+id/horizontalScrollView1" 
   android:layout_width="fill_parent" 
   android:layout_height="wrap_content"
   android:fillViewport="true"
   android:scrollbars="horizontal" > 
    <GridView 
        android:layout_height="wrap_content" 
        android:id="@+id/gridView1" 
        android:layout_width="wrap_content" 
        android:horizontalSpacing="10dp"
        android:stretchMode="columnWidth"
        android:scrollbars="horizontal"
        android:verticalSpacing="10dp">
    </GridView>
    </HorizontalScrollView>
</LinearLayout>

gridview_row.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout     
    android:id="@+id/relativeLayout1"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:background="@drawable/border"
    android:padding="5dp">

    <ImageView 
        android:layout_height="64dp" 
        android:id="@+id/imageView1" 
        android:layout_width="64dp" 
        android:src="@drawable/icon" 
        android:layout_alignParentTop="true" 
        android:layout_centerHorizontal="true">
    </ImageView>

    <TextView 
        android:text="TextView" 
        android:layout_height="wrap_content"
        android:id="@+id/textView1" 
        android:layout_width="wrap_content"
        android:layout_below="@+id/imageView1" 
        android:layout_marginTop="2dp"
        android:layout_centerHorizontal="true"
        android:textSize="18sp"></TextView>


</RelativeLayout>

GridviewAdapter.java

package com.paresh.gridviewexample;

import android.view.LayoutInflater;

public class GridviewAdapter extends BaseAdapter
{

    public GridviewAdapter(Activity activity,ArrayList<String> listCountry, ArrayList<Integer> listFlag) {
        super();
        this.listCountry = listCountry;
        this.listFlag = listFlag;
        this.activity = activity;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return listCountry.size();
    }

    @Override
    public String getItem(int position) {
        // TODO Auto-generated method stub
        return listCountry.get(position);
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return 0;
    }

    public static class ViewHolder
    {
        public ImageView imgViewFlag;
        public TextView txtViewTitle;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        ViewHolder view;
        LayoutInflater inflator = activity.getLayoutInflater();

        if(convertView==null)
        {
            view = new ViewHolder();
            convertView = inflator.inflate(R.layout.gridview_row, null);

            view.txtViewTitle = (TextView) convertView.findViewById(R.id.textView1);
            view.imgViewFlag = (ImageView) convertView.findViewById(R.id.imageView1);

            convertView.setTag(view);
        }
        else
        {
            view = (ViewHolder) convertView.getTag();
        }

        view.txtViewTitle.setText(listCountry.get(position));
        view.imgViewFlag.setImageResource(listFlag.get(position));

        return convertView;
    }

}

我的输出应该是

------------       ----------              ------------     ----
Image Image Image Image Image Image Image Image Image Image Image 

Text  Text  Text  Text  Text  Text  Text  Text  Text  Text  Text 
------------       ----------              ------------         --

请帮帮我

您好，请看一下用于 ListViews 和 Gridviews 的 CustomArrayAdapter，尤其是本教程的第 10 点，您将了解如何自定义您的 GridView/ListView（处理方式相同）

这也可能有帮助

如果你对 hotrizontal 方式有问题，试试这个项目：https ://github.com/jess-anders/two-way-gridview
