ListView加checkBox可以实现全选等功能

1.效果图

2.LIteView_item布局

<?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="wrap_content"
    android:layout_marginRight="10dip"
    android:layout_weight="1.0"
    android:layout_marginLeft="10dp"

    android:orientation="horizontal"
    android:descendantFocusability="blocksDescendants"
    android:background="#AAAAAA"
    >

    <CheckBox android:id="@+id/isCheakBox" android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:layout_alignParentRight="true" />
   
    <ImageView android:id="@+id/dailyPic"
        android:contentDescription="dailyPic"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="3.0dip"
        android:src="@mipmap/txt"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"/>
  
    <TextView
        android:id="@+id/dailyName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/dailyPic"
        android:text=""
        android:layout_centerVertical="true"
        android:textColor="#000000"
        android:textSize="12.0sp" />

</RelativeLayout>

 

3.主布局： 只要有checkbox,listView 也行

            public CheckBox cBox;
            ImageView dailyPic;

5.item数据类

class Item {
        private Integer id;
        private String name;
        String address;
    }

6.实现
