Android 横向****列表****实现，可左右滑动，如下图

1.主界面布局代码：activity_main.xml
a.包裹HorizontalScrollView控件是GirdView横向滚动的基本条件b.GirdView外包裹LinearLayout是java代码中参数设置的必要条件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <HorizontalScrollView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_margin="5dp" >

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="fill_parent"
            android:layout_margin="10dp" >

            <GridView
                android:id="@+id/grid"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:gravity="center"
                android:numColumns="auto_fit"
                android:stretchMode="spacingWidthUniform" >
            </GridView>
        </LinearLayout>
    </HorizontalScrollView>

</LinearLayout>

2.主界面GridView列表子项布局文件：list_item.xml

<!--?xml version="1.0" encoding="utf-8"?-->
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/itemlayout" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical">
 
    <imageview android:id="@+id/ItemImage" android:layout_width="80.0dip" android:layout_height="80.0dip" android:layout_gravity="center_horizontal" android:src="@drawable/china">
    </imageview>
 
    <textview android:id="@+id/tvCity" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:text="Title" android:textcolor="#000000">
    </textview>
 
    <textview android:id="@+id/tvCode" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:text="Info" android:textcolor="#000000">
    </textview>
 
</linearlayout>

3.java实现代码：MainActivity.java

package com.example.horizontallistview;

import java.util.ArrayList;
import java.util.List;

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

        GridViewAdapter adapter = new GridViewAdapter(getApplicationContext(),
                cityList);
        gridView.setAdapter(adapter);
    }
