};

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:
