android一行显示多个多选框
项目本来一行显示一个多选框+区域名字
需求：一行显示（多选框+区域名字）*4
本来是用listview解决的，但是布局文件写的有点麻烦。
最后用gridview
附件有gridview项目
以下代码是listview项目
?
布局文件如下?multiple_checkbox_main.xml
?
<?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="wrap_content"
>
<ListView android:id="@+id/listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#00000000"
/>
</LinearLayout>
?
multiple_checkbox_main_row.xml
?
?
<?xml version="1.0" encoding="utf-8"?>
<TableLayout android:layout_width="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content">
<TableRow>
<!--?
这三个很重要
android:focusable="false"
android:focusableInTouchMode="false"
android:clickable="false"

<CheckBox ?
