Question

I m developing a coverflow with android-coverflow http://code.google.com/p/android-coverflow/

Items are loaded form a WebService, so I load the date in a separate thread like this:

//(in MyActivityClass onCreate) 

coverFlow1 = (CoverFlow) findViewById(R.id.coverflow); // coverFlow1 is class member 

new Thread(new Runnable() {
            public void run() {

                MyWebServiceClass.getInstance().getCoverFlowData();

                MyActivityClass.this.runOnUiThread(
                        new Runnable() 
                        {
                            public void run() 
                            {

                                        MyActivityClass.getInstance().loadItems();
                            }
                });

            }
          }).start();

The problem is that coverFlow1 isnt available inside the loadItems method (it s null , even if I load it again with : coverFlow1 = (CoverFlow) findViewById(R.id.coverflow);

Maybe I ve done a bad usage of runOnUiThread ( I m new to Android development) ?

The problem is that coverFlow1 isnt available inside the loadItems
method

Just add coverFlow1 as parameter of your method, isn’t?

MyActivityClass.getInstance().loadItems(CoverFlow flow);

Also you should call it as MyActivityClass.this.loadItems(CoverFlow flow);

getInstance() there is no reason and you really don’t need and it’s incorrect.
