How to use notifyDataSetChanged() in thread

Question

I create a thread to update my data and try to do notifyDataSetChanged at my ListView.

private class ReceiverThread extends Thread {

@Override
         


        

Answer 1

access the UI thread from other threads

Activity.runOnUiThread(Runnable)

View.post(Runnable)

View.postDelayed(Runnable, long)

my approach whe i use other Threads for work:

private AbsListView _boundedView;
private BasicAdapter _syncAdapter;

 /** bind view to adapter */
public void bindViewToSearchAdapter(AbsListView view) {
    _boundedView = view;
    _boundedView.setAdapter(_syncAdapter);
}

/** update view on UI Thread */
public void updateBoundedView() {
    if(_boundedView!=null) {
        _boundedView.post(new Runnable() {
            @Override
            public void run() {
                if (_syncAdapter != null) {
                    _syncAdapter.notifyDataSetChanged();
                }
            }
        });
    }
}

btw notifyDatasetChanged() method hooks to DataSetObservable class object of AbsListView which is set first by involving AbsListView.setAdaptert(Adapter) method by setting callback to Adapter.registerDataSetObserver(DataSetObserver);
