At least it's strange to me...
My goal is to display a list of items each with a checkbox and when
the user selects some and hits an OK button, I save those items to a
database.
I'm starting slow and currently trying to display a list of checkboxes
and be able to check various items. The list of items is pretty long
(scrolls off the screen) and I've noticed that when I select an item,
every item about ten places away also gets checked.
What's going on with my list? Do I need to create a custom
ListAdapter to get the correct behavior?
Thanks

My ListActivity class:
public class ItemList extends ListActivity {
@Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate (savedInstanceState);
setContentView (R.layout.itemlist);
Button okButton = (Button)findViewById (R.id.itemlist_ok);
okButton.setOnClickListener (new View.OnClickListener() {
@Override
public void onClick (View v) {
setResult (RESULT_OK);
finish ();
}
});
fillList ();
}
private void fillList ()
{
ArrayList <String> items = new ArrayList <String> ();
// ... fill list...
ArrayAdapter <String> adapter = new ArrayAdapter <String> (this,
R.layout.list_element, comics);
setListAdapter (adapter);
}
}
list_element.xml contains:
<?xml version="1.0" encoding="utf-8"?>
<CheckBox id="@+id/listelement"
xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
and itemlist.xml contains:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<ListView android:id="@+id/android:list"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:choiceMode="multipleChoice"/>
<Button android:id="@+id/itemlist_ok"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="OK"/>
</LinearLayout>
