Android GridView中存在checkbox的自定义dialog
在项目中遇到了要使用自定义的dialog，其中要存在gridview，gridview中要存在checkbox。
直接贴代码：
主布局：mainlayout
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="点击选择楼层"/>
</RelativeLayout>
布局名称 ：checkdialog

gridview 的item布局名称：gridview_item_floor

布局中包括圆角矩形和checkbox的图片转换
白底的圆角矩形：tab_rectangle
<?xml version="1.0" encoding="utf-8"?>

全选checkbox的图片转换:selector_radio
