POCheck boxes goes to checked automatically in Android
text
Body
copied!<p>I have a List View that has several rows created by inflator, each row has two TextView and three check boxes. Everything work ok, but when I uses my finger to scroll down or up I noted that some check box goes to checked automatically. I don't know why it does this when using scroll. </p> <p>my code : </p> <pre><code> public class InteractiveArrayAdapter extends ArrayAdapter<Student> implements Filterable { final String NAMESPACE = "http://ws.sams.com";
