Question

I like to create a ListView that its list item can be checked, but I have create my own self a layout for display of ListView and I don’t know how to make them be checked-able.
So, can anyone give some advice? The code below will explain more clearly for my question. The code below shown if we want to make the list item checked-able, we put this :

setListAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_checked,presidents));

but How about if my code is like this?There is other layout inside it :

ArrayAdapter<String> list = new ArrayAdapter<String>(NotificationView.this,R.layout.friendlist_item, R.id.friend_name,people);
lv.setAdapter(list); 

Thanks..

here is friendlist_item.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<TextView android:id="@+id/friend_name"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="10dip"
    android:textSize="20dip"
    android:textStyle="bold"/>  

</LinearLayout>  

and view.xml here:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:background="#ffffff">

<ListView android:id="@android:id/list" 
  android:layout_width="wrap_content" 
  android:layout_height="wrap_content" 
  android:layout_weight="1">
</ListView>

<FrameLayout android:id="@+id/FrameLayout01" 
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content">


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


      <Button
          android:id="@+id/acceptbtn"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_gravity="center_horizontal"
          android:layout_weight="0.46"
          android:text="Accept" />


      <Button
          android:id="@+id/closebtn"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_weight="0.49"
          android:text="Close" />

  </LinearLayout>

 </FrameLayout>

 </LinearLayout>

Your friendlist_item.xml currently only has a TextView widget to display in each List item.

If you want a checkbox, you should replace(or add) a CheckBox widget. Part of their example, and a quick adaptation to your code follows:

<!-- language: lang-java  -->
<CheckBox android:id="@+id/checkbox_meat"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/meat"
    android:onClick="onCheckboxClicked"/>

<CheckBox android:id="@+id/friend_name"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:padding="10dip"
    android:textSize="20dip"
    android:textStyle="bold"/>
