I think you should run this long-running task off the UI thread. When you click button in OnClickListener:

new Thread(new Runnable() {
                    @Override
                    public void run() {
                        for (int i = 0; i < list.getAdapter().getCount(); i++) {
                            final int position = i;
                            mHandler.post(new Runnable() {
                                @Override
                                public void run() {
                                    list.setItemChecked(pos, true);  
                                }
                            });
                        }
                    }
                }).start();    

and in onCreate() :

this.mHandler = new Handler();

Each item in list view should be Checkable like CheckableRelativeLayout that implements Checkable interface.
