在项目开发过程中，常常需要对用户列表的信息进行删除的操作。Android中常用的删除操作方式有两种 ，一种就是类似微信的滑动出现删除按钮方式，还有一种是通过CheckBox进行选择，然后通过按钮进行删除的方式。本来的实例集成上述的两种操作方式来实现用户列表删除的效果。

设计思路：在适配器类MyAdapter一个滑动删除按钮显示或隐藏的Map,一个用于CheckBox是否选中的Map和一个与MainAcitivyt进行数据交互的接口ContentsDeleteListener，同时该接口包含两个方法，contentsDeleteSelect(int position, boolean isChecked)方法用于将选中或取消内容从选中List中加入或删除，contentDelete(int position)用于删除List中指定位置的列项。滑动的效果主要是通过当滑动的距离大于40时，显示滑动删除按钮，再执行删除操作时，将其他所有设置不可见，并设置CheckBox为不选中状态。

一.代码实现效果

二.代码实现

1. 主界面布局 activity_main.xml

<span style="font-size:18px;"><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
    <Button
	    android:id="@+id/my_delete_btn"
	    android:layout_width="match_parent"
	    android:layout_height="wrap_content"
	    android:layout_alignParentBottom="true"
	    android:text="@string/delete"
	    />
    <ListView
        android:id="@+id/my_lv"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentTop="true"
        android:layout_above="@id/my_delete_btn"
       	android:contentDescription="@string/member_list"/>

</RelativeLayout>
</span>

2.用户项布局 activity_main_list_view.xml

<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/my_rl"
    android:layout_width="match_parent"
    android:layout_height="200dp" >

    <CheckBox
        android:id="@+id/my_select_cb"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:layout_marginLeft="10dp"
        android:background="@drawable/my_list_checkbox_selector"
        android:button="@null" />

    <TextView
        android:id="@+id/my_content_tv"
        android:layout_width="wrap_content"
        android:layout_height="60dp"
        android:layout_centerInParent="true"
        android:layout_marginLeft="20dp"
        android:layout_toRightOf="@id/my_select_cb"
        android:gravity="center"
        android:text="@string/delete" />

    <TextView
        android:id="@+id/my_delete_tv"
        android:layout_width="80dp"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_centerInParent="true"
        android:layout_marginLeft="5dp"
        android:clickable="true"
        android:drawableLeft="@drawable/del_icon_normal"
        android:gravity="center"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:text="@string/delete"
        android:visibility="gone" />

</RelativeLayout></span>

3.滑动效果anim_right_left.xml

<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

    <translate
        android:duration="200"
        android:fromXDelta="320"
        android:fromYDelta="0"
        android:toXDelta="0"
        android:toYDelta="0" />

</set></span>

<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
     <item android:drawable="@drawable/my_list_check_box_bg_check" android:state_checked="true"></item>  
    <item android:drawable="@drawable/my_list_check_box_bg_check" android:state_selected="true"></item>  
    <item android:drawable="@drawable/my_list_check_box_bg_check" android:state_pressed="true"></item>  
    <item android:drawable="@drawable/my_list__check_box_bg"></item>  
</selector>
</span>
