一.列表中每项的布局文件
<?xml

xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width=
"match_parent"

android:orientation=
"vertical"
>
<TextView
android:id="@+id/catalog"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#E0E0E0"
android:layout_weight="1.0"
android:paddingLeft="5dip"
android:paddingTop="5dip"
android:paddingBottom="5dip"
android:textSize="13dp"
android:textColor="@color/index_font"
android:text="A"/>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="60dip"
android:background="@color/white"

android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center_vertical"
android:layout_toRightOf="@+id/select_staff_photo"
android:layout_marginLeft="10dip"
>
<TextView
android:id="@+id/select_staff_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="2dip"
android:textSize="16dp"
android:textColor="@color/main_font"

</LinearLayout>
<RelativeLayout
android:id="@+id/ry_phone_staff"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_marginRight="15dip"
>
<CheckBox

<View

android:layout_height="1dip"

</LinearLayout>
对复选框修饰的样式文件 @style/DeptCheckboxTheme
style.xml 中加入
<style
name="DeptCheckboxTheme"
parent="@android:style/Widget.CompoundButton.CheckBox"
>
<item
name=
"android:button">@drawable/dept_checkbox_style
</item>
</style
>
资源文件dept_checkbox_style.xml
<?xml
version=
"1.0"
encoding
="utf-8"?>
<selector
xmlns:android="http://schemas.android.com/apk/res/android"
>
<item
android:drawable=
"@drawable/work_diary_checkbok_pre"
android:state_checked="true"

<item
android:drawable=
"@drawable/work_diary_checkbok"
android:state_checked="false"
/>
<item
android:drawable=
"@drawable/work_diary_checkbok"
/>

二.适配器编写
1.在适配器中用一个map变量存储选择的值
2.在复选框组件上注册OnCheckedChangeListener事件 在该事件中将选择的值保存到map中

三.将数据库中选择的数据进行回显

Boolean
checked
=

.get(staff.getId());
viewHolder.
