我目前正在使用列表视图但这对我不起作用所以我想要使用表视图和行来实现相同的效果。例如，我有一个json feed和新闻故事，每个新闻故事都会创建一个包含图像和textview的行，并用json中的数据填充它。
所以我的问题是，是否有人知道如何做到这一点？
这是我到目前为止所拥有的：
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@color/white">
<include layout="@layout/header" />
<include layout="@layout/redcell" />
<TableRow
android:id="@+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="100dp" >
<TextView
android:id="@+id/fixtures_text"
android:layout_width="match_parent"
android:layout_height="60dp"
android:gravity="center"
android:text="@string/leagues"
android:textColor="@color/white"
android:textSize="25dp"
android:textStyle="bold"/>
</TableRow>
<include layout="@layout/redcell" />
<TableRow
android:id="@+id/tableRow2"
android:layout_width="wrap_content"
android:layout_height="100dp" >
<TextView
android:id="@+id/_text"
android:layout_width="match_parent"
android:layout_height="60dp"
android:gravity="center"
android:text="@string/leagues"
android:textColor="@color/white"
android:textSize="25dp"
android:textStyle="bold"/>
</TableRow>
<include layout="@layout/redcell" />

您可以设置一个自定义适配器，将ArrayAdapter扩展为ListActivity使用的适配器。在该自定义适配器的getView（）方法中，您可以加载新闻列表中每个项目的图像和文本。
具有水平方向的简单LinearLayout可能最适合自定义适配器中的行布局。如果将TextView的layout_weight设置为1并使图像保留为layout_weight，则会将图像推送到行的一侧。
