如何在android中的http请求中添加用户名和密码
如何在http请求中添加用户名和密码来调用Web服务？我已经编写了 REST Web 服务，如果用户想要发出请求，他需要在终端中这样请求： curl -u username:password http://localhost:8080/user/folder
httpclient.getCredentialsProvider().setCredentials(new AuthScope(null, -1),
new UsernamePasswordCredentials("kyaw", "password"));
get.setHeader("Authorization","Basic a31hdzpwYXNzd29yZA==");
我使用了任何一种方法在 android 中但出现异常：
05-20 07:13:30.900: DEBUG/AndroidRuntime(557): Shutting down VM
05-20 07:13:30.900: WARN/dalvikvm(557): threadid=1: thread exiting with uncaught exception (group=0x40015560)

我该怎么办？

错误是“您必须提供layout_width属性”（从堆栈跟踪中复制粘贴）。
该错误与您显示的代码无关。您的某个组件 XML 声明中缺少
layout_width=""属性。The error is "You must supply a layout_width attribute" (copy pasted from your stack trace).
The error is unrelated to the code you are showing. You are missing a
layout_width=""attribute in one of your components XML declaration.
