Question

我一直在splashscreen.java中收到与Thread.stop（）相关的错误。我很擅长并且知道已弃用的Thread.stop（）但有人可以在这里解释一下我做错了什么，谢谢......

    java.lang.UnsupportedOperationException
    at java.lang.Thread.stop(Thread.java:1076)
    at java.lang.Thread.stop(Thread.java:1063)
    at com.dapp.d.SplashScreen$4.run(SplashScreen.java:88)

这是splashscreen.java的完整源代码

    super.onCreate(savedInstanceState);

    RelativeLayout relativeLayout = (RelativeLayout)findViewById(R.id.splashRelativeLayout);
    relativeLayout.setOnClickListener(new OnClickListener() {

        @Override

            // TODO Auto-generated method stub
            Uri uri = Uri.parse("http://www.exmaple.com");
            Intent intent = new Intent(Intent.ACTION_VIEW, uri);

    try{

                        waited += 100;

        };
        splashTread.start();

    }catch (Exception e) {
        // TODO: handle exception
    }
}

    }

Answer 1

我认为你根本不需要打电话到那里。您的线程不循环，因此它将执行并正常结束。尝试删除stop（）;

Answer 2

我遇到了类似的问题，解决方法是将stop方法包装在try / catch语句中，并在catch中使用Throwable t。它会起作用。
