Android开发ListView中包含CheckBox（点击item选中CheckBox），并设置其全选反选等功能

要实现ListView中CheckBox的选中并记录，我的做法是自己写一个Adapter，继承于BaseAdapter，ListView中的CheckBox需要将focusable，clickable的属性都设置为false，防止CheckBox将点击事件拦截，在ListView的onItemClick方法中接收点击事件并对数据进行处理。废话不多说，上代码。

先给大家看一下listview中数据的xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent" >    <TextView     android:id="@+id/tv"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_alignParentLeft="true" /><CheckBox     android:id="@+id/cb"    android:layout_height="wrap_content"    android:layout_width="wrap_content"    android:focusable="false"    android:clickable="false"    android:layout_alignParentRight="true" /></RelativeLayout>

然后再看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="fill_parent"    android:orientation="vertical" >    <ListView        android:id="@+id/lv"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:background="#00000000"        android:listSelector="#00000000"        android:scrollbars="none"        android:fadingEdge="none" /></LinearLayout>

最后把主代码给大家
