兔子--如何模拟耗时操作？

 public void longRunning(long time) {
        Toast.makeText(this, "----耗时任务开始执行---", Toast.LENGTH_SHORT).show();
        long endTime = System.currentTimeMillis() + time;
        while (System.currentTimeMillis() < endTime) {
            synchronized (this) {
                try {
                    wait(endTime - System.currentTimeMillis());
                } catch (Exception e) {

                }

            }
        }

        Toast.makeText(this, "----耗时任务执行完成---", Toast.LENGTH_SHORT).show();
    }
