要想實現滾動顯示，layout佈局裡必須要使用HorizontalScrollView，才能實現橫向滑動，但HorizontalScrollView標籤裡要巢狀一個LinearLayout佈局

activity_main.xml,如下:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height
 
="match_parent"
    tools:context=".MainActivity"
    android:orientation="vertical"
    android:weightSum="2" >

   <HorizontalScrollView
        android:id="@+id/horizontal_scrollview"
        android:layout_height="0dp"
        android:layout_width="fill_parent"
        android:layout_weight="1"
 

        android:layout_gravity="center"
        android:background="@android:color/darker_gray"
        android:scrollbars="none">
            <LinearLayout
                android:layout_height="match_parent"
                android:layout_width="match_parent"
                android:orientation
 
="horizontal">
                 <GridView
                     android:id="@+id/test_gridview"
                     android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_gravity="center"/>
            </LinearLayout>
    </HorizontalScrollView>
</LinearLayout>

gridview中的item的佈局如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="80dp"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <ImageView 
        android:id="@+id/item_img"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:layout_gravity="center_horizontal"
        android:scaleType="fitXY"
        android:background="#00000000"/>
    <TextView 
        android:id="@+id/item_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:textSize="20dp"
        android:text="233"
        android:textColor="@android:color/white"/>
</LinearLayout>

實現類如下：

package com.example.scrollgridview;

import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.util.DisplayMetrics;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

public class MainActivity extends Activity {

    private GridView gridview;
    private int imgs[]={R.drawable.remote_tv_0,
            R.drawable.remote_tv_1,R.drawable.remote_tv_2,
            R.drawable.remote_tv_3,R.drawable.remote_tv_4,
            R.drawable.remote_tv_5,R.drawable.remote_tv_6,
            R.drawable.remote_tv_7,R.drawable.remote_tv_8,
            R.drawable.remote_tv_9};
    private GridviewAdapter adapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        gridview = (GridView)findViewById(R.id.test_gridview);
        adapter = new GridviewAdapter();

        DisplayMetrics dm = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(dm);
        float density = dm.density;
        int size = imgs.length;//要顯示資料的個數
        //gridview的layout_widht,要比每個item的寬度多出2個畫素，解決不能完全顯示item的問題
        int allWidth = (int) (82 * size * density);
        //int allWidth = (int) ((width / 3 ) * size + (size-1)*3);//也可以這樣使用，item的總的width加上horizontalspacing
        int itemWidth = (int) (80 * density);//每個item寬度
        LinearLayout.LayoutParams params = new         
        LinearLayout.LayoutParams(allWidth,LinearLayout.LayoutParams.MATCH_PARENT);
        gridview.setLayoutParams(params);
        gridview.setColumnWidth(itemWidth);
        gridview.setHorizontalSpacing(3);
        gridview.setStretchMode(GridView.NO_STRETCH);
        gridview.setNumColumns(size);

        gridview.setAdapter(adapter);
        adapter.setindex(0);
        adapter.notifyDataSetChanged();

        gridview.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                // TODO Auto-generated method stub
                adapter.setindex(position);
                adapter.notifyDataSetChanged();
            }
        });
    }

    class GridviewAdapter extends BaseAdapter{
        private int index = 0;
        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return imgs.length;
        }

        @Override
        public Object getItem(int position) {
            // TODO Auto-generated method stub
            return imgs[position];
        }

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

        public void setindex(int index){
            this.index = index;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub
            LayoutInflater mInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            ViewHolder viewHolder;
            if (convertView == null) {
                convertView = mInflater.inflate(R.layout.gridview_itme, null);
                viewHolder = new ViewHolder();
                viewHolder.img = (ImageView)convertView.findViewById(R.id.item_img);
                viewHolder.text = (TextView)convertView.findViewById(R.id.item_text);
                convertView.setTag(viewHolder);
            }else{
                viewHolder = (ViewHolder)convertView.getTag();
            }
            if(this.index == position){
                convertView.setBackgroundResource(R.drawable.list_item_bg_focus);
            }
            else{
                convertView.setBackgroundResource(R.drawable.list_item_bg);
            }
            viewHolder.img.setImageResource(imgs[position]);
            viewHolder.text.setText(position+"");
            return convertView;
        }

        class ViewHolder{
            ImageView img;
            TextView text;
        }
    }

}
