[android-developers] ListView/Adapter IllegalStateException
I've implemented a custom ListView and Adapter, and sometimes I
receive IllegalStateException exception:” ERROR/AndroidRuntime(3575):
java.lang.IllegalStateException: The content of the adapter has
changed but ListView did not receive a notification. Make sure the
content of your adapter is not modified from a background thread, but
only from the UI thread.”
Here is some code example:
public interface BuddyChangeListener {
void onChange(List buddys);
}
public class BuddyListView extends ListView implements
BuddyChangeListener
public void onChange(List Buddy) {
MyActivity.instance.handler.post(new Runnable() {
public void run() {
if (((BuddyAdapter) refreshListView.getAdapter()) !
= null) {
((BuddyAdapter)
refreshListView.getAdapter()).update(Buddy);
}
}
});
}
public class BuddyAdapter extends BaseAdapter {
private List buddyList;
public BuddyAdapter (Context context, List buddyList) {
this.buddyList= buddyList;
}
public void update(List buddyList) {
this.buddyList= buddyList;
this.notifyDataSetChanged();
}
}
Every time when the content of the list need to be updated I run from
onChange method and I use a handler to change the adapter content,to
update the content from UI thread.
Can someone to tell me if I have made something wrong on update ?
Thanks.
