Android: saving checkbox-state of ListView items into instances of custom object

My ultimate goal is to store an instance of the custom object "Place" for each item of the ListView in an SQLite table.

step 1 would be simply extracting the Place objects and I was able to get the various member variables of Place using an adapter but I have been trying for days to get the checked-state of each checkbox within the listview but cannot get it to work and it shouldn't be that difficult. I have tried every listener I can think of but it is not registering when I check a box. Finally, I do need the checked-state as an integer (1 or 0) rather than a boolean so I can save it to the database. Below I have posted the code for a tester app version I have been working on so I stop screwing up the real thing and I really would appreciate any help!

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/linearlayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">

<CheckBox
    android:id="@+id/checkbox"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical"
    android:gravity="center_vertical"
    android:onClick="itemClicked"
    android:paddingRight="8dp"/>

<TextView
    android:id="@+id/place_nameandaddress"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_vertical"
    android:gravity="center_vertical"
    android:minHeight="?android:listPreferredItemHeight"/>

</LinearLayout>
