如何将列表传递给主线程？

有一个线程在其中填充和生成列表。需要将其转移到适配器中的主线程，如何做到这一点？

private class LooperThread extends Thread implements Handler.Callback{

    Handler handler;

    @Override
    public void run() {
        Looper.prepare();
        handler = new Handler(this);
        Looper.loop();
    }

    @Override
    public boolean handleMessage(Message message) {
        if(message.what == 0){
            DepositGeneration generation = new DepositGeneration();
            DepositOperations operations = new DepositOperations(generation.setList());
            List<DepositItem> list = operations.sortedList();
            List<BaseProduct> products = DepositFormatter.setProducts(list);

        }
        return true;
    }

    public Handler getHandler() {
        return handler;
    }
}
