当我点击提交按钮...当我调试时显示为“未找到源”...并在设备中显示应用程序意外停止工作...来源未找到 - 应用程序意外停止工作

Button btnSubmit = (Button) findViewById(R.id.btnSubmit); 
     btnSubmit.setOnClickListener(new View.OnClickListener() {       
      public void onClick(View view) { 
       //finish(); 
       //Intent DiscIntent = new Intent (view.getContext(), Disclaimer.class); 
       //startActivityForResult(DiscIntent, 0); 
       if(ValidateInformation()) 
       { 
        EditText etUserName = (EditText)findViewById(R.id.txtUserName); 

       if(UserNameAvailability(view, etUserName.getText().toString().trim()))

我logcat的细节如下...

我UserNameAvailability功能低于

protected boolean UserNameAvailability(View view, final String sUserName)

{
布尔结果=假;

SoapObject request = new SoapObject(getResources().getString(R.string.targetnamespace), getResources().getString(R.string.usernameavailabilitymethod)); 
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
envelope.dotNet = true; 

PropertyInfo piUserName = new PropertyInfo(); 
piUserName.name = "UserName"; 

request.addProperty(piUserName, sUserName); 

HttpTransportSE httpTransport = new HttpTransportSE(getResources().getString(R.string.webserviceurl));     
    try { 
     httpTransport.debug =true; 
     httpTransport.call(getResources().getString(R.string.usernameavailabilitysoapaction), envelope);      
     SoapPrimitive response = (SoapPrimitive)envelope.getResponse(); 
     if (!response.toString().equals("false")) { 
      result = true; 

     } 
     else 
     { 
      alertBox("User Name already exists.Please enter different username."); 
     } 

     }catch (Exception exception) { 
     Log.w("UserRegistration - RegisterActivity", exception.getMessage()); 
     } 


     return result;

}

我的完整的按钮单击事件低于

Button btnSubmit = (Button) findViewById(R.id.btnSubmit); 
     btnSubmit.setOnClickListener(new View.OnClickListener() {       
      public void onClick(View view) { 
       //finish();

       { 
        EditText etUserName = (EditText)findViewById(R.id.txtUserName); 

       if(UserNameAvailability(view, etUserName.getText().toString().trim())) 
       { 
       EditText etFirstName = (EditText)findViewById(R.id.txtFirstName); 
       EditText etLastName = (EditText)findViewById(R.id.txtLastName);   
       EditText etEmail = (EditText)findViewById(R.id.txtEmail);

       EditText etOrganization = (EditText)findViewById(R.id.txtOrganization); 
       EditText etRegion = (EditText)findViewById(R.id.txtRegionCountry); 
       EditText etPassword = (EditText)findViewById(R.id.txtPassword); 
       EditText etConfirmPassword = (EditText)findViewById(R.id.txtConfirmPassword);//Added By Prakash 
       //EditText etUserName1 = (EditText)findViewById(R.id.txtUserName); 



       Bundle bunUserInfo = new Bundle(); 
       bunUserInfo.putString("UserName", etUserName.getText().toString()); 
       bunUserInfo.putString("FirstName", etFirstName.getText().toString()); 
       bunUserInfo.putString("LastName", etLastName.getText().toString());

       }

      } 
     });

你确定你的整个代码只是那么多吗？ – Ghost 2012-01-12 11:36:51

您可能想要发布函数UserNameAvailability的来源以及发生异常:) – Fge 2012-01-12 11:37:15

您的日志说您的RegisterActivity类的第236行中，您尝试记录没有任何消息文本的警告消息。 – THelper 2012-01-12 11:39:32

我的猜测是，UserNameAvailability某处null参数调用Log.w。

在UserNameAvailability中查找对Log.w的调用，其中标记或消息为空。

我无法弄清楚...我发布了我的整个代码...你可以看看它并说我显然...对不起...我是新的Android开发 – Prakash 2012-01-12 12:07:32

我觉得exception.getMessage（）似乎为空，而不是使用一些常量字符串或exeption.printStacktrace（）。 – Vamsi 2012-01-12 12:25:02

改变这一行

Log.w("UserRegistration - RegisterActivity", exception.getMessage());

到

Log.w("UserRegistration - RegisterActivity", "Error message is "+exception.getMessage(), exception);

这样，你将永远有一个消息（和你的日志堆栈跟踪），即使exception.getMessage()函数返回null;
