学习android的新手，在做例子中不断前行，感谢大家给我帮助，这里遇到了一个问题，恳请各位大哥大姐指教！

做的是一个验证用户登录的例子。用的是webservice，这个webservice代码是没有问题的，就是一个UserLogin方法，参数是用户名和密码，调用方法后返回true或false，表示用户名和密码是否都正确。android代码，我改编自手机归属地验证的程序，这个程序本身也是正确的，我已经调试过，可以运行，我照葫芦画瓢，改成验证用户的程序，就有错误提示了，实在看不出在什么地方了。

一个错误是出在“getRemoteInfo(UserName,Pwd);” ，提示的错误信息是“Cannot make a static reference to the non-static method getRemoteInfo(String, String) from the type MainActivity”。

一个错误是出在“TextViewResult.setText(msg.obj.toString());”，提示的错误信息是“TextViewResult cannot be resolved”。

肯定各位android长辈，帮我看看，问题出在什么地方了，怎么解决？谢谢啦！
我的开发平台是android4.4。

String UserName = UserNameEditText.getText().toString().trim(); 
                    String Pwd = PassEditText.getText().toString().trim();                   
                    TextViewResult.setText("用户名" + UserName  + "," + "密码" + Pwd);
                     
                    Thread th= new Thread(new Runnable() {
 
                        @Override
                        public void run() {
                         
                            getRemoteInfo(UserName,Pwd);
 
                        }
                        });
                     
                    th.start();

你确定这段能编译通过？

[lostmoon]

不能。错误就是我描述中写的

[風言楓語]

Cannot make a static reference to the non-static method getRemoteInfo(String, String) from the type MainActivity 不能做一个静态引用非静态方法getRemoteInfo MainActivity类型(字符串,字符串) 你在静态方法里面调用了非静态方法

[奋斗中的显摆]

public static class PlaceholderFragment extends Fragment 你为什么要把它定义成static的？ 没有理解；去掉static 应该就没问题了；static 的话说明这个类 是不属于MainActivity，你不能直接调用MainActivity的方法

[张大熊]

public void getRemoteInfo(String username,String password){.....} 改成 public static void getRemoteInfo(String username,String password){.....} TextViewResult.setText(msg.obj.toString()) 改成TextViewResult.setText((String)msg.obj); 感觉你不需要把那个类定义成静态的,不知道你的代码是哪里来的
