    }
    people.isSelect = !people.isSelect;
   }

};

public ArrayList<PeopleVO> getPeoples() {
   return peoples;
}

public void setPeoples(ArrayList<PeopleVO> peoples) {
   this.peoples = peoples;
   notifyDataSetChanged();
}

public void addPeople(PeopleVO people) {
   if (peoples == null) {
    peoples = new ArrayList();
   }
   peoples.add(people);
}

Activity 继承 ListActivity

在onCreate中设置Adapter

setListAdapter(new PeoplesAdapter (this));

list_people.xml:

<?xml version="1.0" encoding="utf-8"?>


<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="horizontal" android:layout_width="fill_parent"
   android:layout_height="wrap_content">

   <ImageView android:layout_width="wrap_content"
    android:layout_height="fill_parent" android:id="@+id/imgCheck" android:src="@drawable/checkbox_off_background" />

   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="fill_parent"
    android:layout_height="fill_parent" android:layout_weight="8">
    <TextView android:id="@+id/txtPeopleName"
     android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="32px" />

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:orientation="horizontal" android:layout_width="fill_parent"
     android:layout_height="fill_parent">
     <TextView android:layout_width="wrap_content"
      android:layout_height="wrap_content" android:text="手机:" />
     <TextView android:layout_width="fill_parent" android:id="@+id/txtPeopleMobile"
      android:layout_height="wrap_content" />
    </LinearLayout>

   </LinearLayout>
</LinearLayout>

效果如下:
