好的，这里是自定义对话框类的完整工作代码，其中包含一个包含 listView 的选项卡式布局。第一个选项卡有一个 listView ，其中行是 textView 和 imageView ，其中 imageView 是右对齐的。第二个选项卡有一个 listView，其中行是一个 textView。滚动条设置为较长的淡入淡出持续时间，以使其始终显示。对话框窗口本身设置为静态大小，以防止对话框在切换选项卡时调整大小。对话窗口也位于屏幕下方，而不是中心。listViews 使用自定义适配器，并且第二个选项卡的 listView 注册为上下文菜单。
我已将所有内容重命名为更通用，并且不包含我们产品的名称，因此我在重命名时可能会出现一些拼写错误，但我认为一切都是正确的。尽我所能对代码进行注释。希望这可以帮助一些人。
customDialog 的 XML (custom_dialog_layout.xml)：
<?xml version="1.0" encoding="utf-8"?>
<TabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/TabHost01"
android:layout_width="fill_parent"
android:layout_height="300dip">
<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ListView
android:id="@+id/listView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:scrollbarFadeDuration="1000000"/>
<ListView
android:id="@+id/listView02"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:scrollbarFadeDuration="1000000"/>
</FrameLayout>
</LinearLayout>
</TabHost>
选项卡 1 listView 行 XML (list_view_01_row.xml)。这是一个左对齐的 textView 和一个右对齐的 imageView。textView 已设置为更大的高度，以强制 listView 行更高。listView 也已设置为特定宽度，这会将 imageView 推到右侧以使其右对齐。
<?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"
android:paddingBottom="5dip"
android:paddingTop="5dip"
android:paddingLeft="10dip"
android:paddingRight="10dip">
<TableLayout
android:id="@+id/list_view_01_row_table_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stretchColumns="0">
<TableRow
android:id="@+id/list_view_01_row_table_row"
android:gravity="center_vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="@+id/list_view_01_row_text_view"
android:textSize="18sp"
android:textColor="#ffffff"
android:gravity="center_vertical"
android:layout_width="200dip"
android:layout_height="75dip" />
<ImageView
android:id="@+id/list_view_01_row_image_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</TableRow>
</TableLayout>
</LinearLayout>
选项卡 2 listView 行 XML (list_view_02_row.xml)。与选项卡 1 相同，但只有一个 textView，没有 imageView。
<?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"
android:paddingBottom="5dip"
android:paddingTop="5dip"
android:paddingLeft="10dip"
android:paddingRight="10dip">
<TableLayout
android:id="@+id/list_view_02_row_table_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stretchColumns="0">
<TableRow
android:id="@+id/list_view_02_row_table_row"
android:gravity="center_vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView

android:textSize="18sp"
android:textColor="#ffffff"
android:gravity="center_vertical"
android:layout_width="fill_parent"
android:layout_height="75dip" />
</TableRow>
</TableLayout>
</LinearLayout>
