我们知道很多
软件都有设置菜单项如
微信墨迹天气等的设置界面。当设置里有很多选项这时我们可以选择使用ListView实现。
布局文件如下：
[html] <?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:background="@drawable/splash_background"
>
<ListView
Android:id="@+id/more_List"
Android:layout_width="fill_parent"
Android:layout_height="fill_parent"
Android:divider="@drawable/list_bottom_line"
Android:listSelector="#00000000"
Android:cacheColorHint="#00000000">
</ListView>
</LinearLayout>
<?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:background="@drawable/splash_background"
>
<ListView
Android:id="@+id/more_List"
Android:layout_width="fill_parent"
Android:layout_height="fill_parent"
Android:divider="@drawable/list_bottom_line"
Android:listSelector="#00000000"
Android:cacheColorHint="#00000000">
</ListView>
</LinearLayout>很简单只有一个ListView
item的布局：
[html] <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:
Android="http://schemas.
Android.com/apk/res/
Android"
Android:orientation="horizontal"
Android:layout_width="wrap_content"
Android:layout_height="wrap_content"
Android:padding="8dip"
Android:background="@drawable/list_item"
>
<ImageView
Android:id="@+id/item_icon"
Android:layout_width="wrap_content"
Android:layout_height="wrap_content"
/>
<TextView
Android:id="@+id/more_item_text"
Android:layout_marginLeft="10dip"
Android:textSize="20dip"
Android:textColor="#000000"
Android:layout_width="wrap_content"
Android:layout_height="wrap_content"/>
<ImageView
Android:id="@+id/item_image"
Android:layout_marginTop="5dip"
Android:layout_marginLeft="10dip"
Android:layout_width="wrap_content"
Android:layout_height="wrap_content"
Android:background="@drawable/triangle"
/>
</LinearLayout>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:
Android="http://schemas.
Android.com/apk/res/
Android"
Android:orientation="horizontal"
Android:layout_width="wrap_content"
Android:layout_height="wrap_content"
Android:padding="8dip"
Android:background="@drawable/list_item"
>
<ImageView
Android:id="@+id/item_icon"
Android:layout_width="wrap_content"
Android:layout_height="wrap_content"
/>
<TextView
Android:id="@+id/more_item_text"
Android:layout_marginLeft="10dip"
Android:textSize="20dip"
Android:textColor="#000000"
Android:layout_width="wrap_content"
Android:layout_height="wrap_content"/>
<ImageView
Android:id="@+id/item_image"
Android:layout_marginTop="5dip"
Android:layout_marginLeft="10dip"
Android:layout_width="wrap_content"
Android:layout_height="wrap_content"
Android:background="@drawable/triangle"
/>
</LinearLayout>设置成水平布局，一次是图标，文字说明，箭头图标

下面是为ListView提供数据的Adapter：

public class MoreAdapter extends BaseAdapter{

public static final List<String> more_list = new ArrayList<String>();//为条目提供数据

运行效果图如下：
