带有图像和文本的Android自定义ListView

Question

首先很抱歉沟通不畅，我使用了自定义数组适配器，并且图像和名称列表正在我的应用程序中显示gridview控件。图像和名称来自sql server数据库，现在显示所有图像绑定并显示到gridview到显示幻灯片类型的图像，即第一列显示3张图像，然后单击图像幻灯片到接下来的3张图像显示。任何人都可以帮助我。

我的代码是：

enquiryfrm.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Select Name"/>
    <Spinner
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    <ScrollView
        android:id="@+id/questionListSV"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:fillViewport="true">


    <GridView
        android:id="@+id/gridviewimg"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:numColumns="3"
        android:horizontalSpacing="10dp"
        android:scrollbars="horizontal"
        android:scrollbarAlwaysDrawHorizontalTrack="true"
        android:scrollbarAlwaysDrawVerticalTrack="true"
        android:stretchMode="none"
        android:columnWidth="100dp"
        android:paddingBottom="60dp"/>   
    </ScrollView>
    <Spinner
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

    </Spinner>

</LinearLayout>

您的问题无法理解。 据我了解，尝试使用水平listview。
