NetworkOnMainThreadException崩溃android应用程序

我构建了一个webservice并使用SoapUI进行了测试，一切正常。现在当我尝试提交表单来注册一个用户时，我得到了NetworkOnMainThreadException错误。看起来主线需要做很多工作。NetworkOnMainThreadException崩溃android应用程序

你可以帮助我使用AsyncTask和doInBackground（）方法吗？我该在哪里以及如何做到这一点？在我的用户注册布局类（RegUser.java）或插入方法是（UserDAO.java）？

RegUser.java

public class RegUser extends Activity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.user); 

    final EditText username = (EditText) findViewById(R.id.username); 
    final EditText email = (EditText) findViewById(R.id.email); 
    final EditText password = (EditText) findViewById(R.id.password); 
    final EditText salt = (EditText) findViewById(R.id.salt); 
    final EditText nome = (EditText) findViewById(R.id.nome); 
    final EditText sobrenome = (EditText) findViewById(R.id.sobrenome); 
    final EditText telefone = (EditText) findViewById(R.id.telefone); 
    final EditText cel_wts = (EditText) findViewById(R.id.cel_wts); 
    final EditText rua = (EditText) findViewById(R.id.rua); 
    final EditText numero = (EditText) findViewById(R.id.numero); 
    final EditText bairro = (EditText) findViewById(R.id.bairro); 
    final EditText cidade = (EditText) findViewById(R.id.cidade); 
    final EditText estado = (EditText) findViewById(R.id.estado); 
    final EditText pais = (EditText) findViewById(R.id.pais); 
    final EditText cpf_cnpj = (EditText) findViewById(R.id.cpf_cnpj); 
    final EditText empresa= (EditText) findViewById(R.id.empresa); 
    final EditText cargo = (EditText) findViewById(R.id.cargo); 

    final Button cadProfile = (Button) findViewById(R.id.cadProfile); 

    cadProfile.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      UserDAO dao = new UserDAO(); 
      boolean resultado = dao.insertUser(new User(0, username.getText().toString(), 
        email.getText().toString(), 
        password.getText().toString(), 
        salt.getText().toString(), 
        nome.getText().toString(), 
        sobrenome.getText().toString(), 
        telefone.getText().toString(), 
        cel_wts.getText().toString(), 
        rua.getText().toString(), 
        numero.getText().toString(), 
        bairro.getText().toString(), 
        cidade.getText().toString(), 
        estado.getText().toString(), 
        pais.getText().toString(), 
        cpf_cnpj.getText().toString(), 
        empresa.getText().toString(), 
        cargo.getText().toString())); 

      if(resultado){ 
       finish(); 
      }else{ 
       Toast.makeText(RegUser.this, "Erro ao cadastrar :(", Toast.LENGTH_LONG).show(); 
      } 

     } 
    }); 

} 
}

UserDAO.java

public class UserDAO { 

private static final String URL = "...meuIP:8080/Meuprojeto/services/EventoDAO?wsdl"; 
private static final String NAMESPACE = "...meuprojetoWS.habitodigital.com"; 

private static final String INSERIR = "insertUser"; 
private static final String EXCLUIR = "deletetUser"; 
private static final String ATUALIZAR = "updateUser"; 
private static final String BUSCAR_TODOS = "searchAllUsers"; 
private static final String BUSCAR_POR_ID = "searchUserById"; 


public boolean insertUser(User user){ 

SoapObject insertUser = new SoapObject(NAMESPACE, INSERIR); 
SoapObject usr = new SoapObject(NAMESPACE, "user"); 

usr.addProperty("id", user.getId()); 
usr.addProperty("username", user.getUsername()); 
usr.addProperty("email", user.getEmail()); 
usr.addProperty("password", user.getPassword()); 
usr.addProperty("salt", user.getSalt()); 

usr.addProperty("nome", user.getNome()); 
usr.addProperty("sobrenome", user.getSobrenome()); 
usr.addProperty("telefone", user.getTelefone()); 
usr.addProperty("cel_wts", user.getCel_wts()); 
usr.addProperty("rua", user.getRua()); 
usr.addProperty("numero", user.getNumero()); 
usr.addProperty("bairro", user.getBairro()); 
usr.addProperty("cidade", user.getCidade()); 
usr.addProperty("estado", user.getEstado()); 
usr.addProperty("pais", user.getPais()); 
usr.addProperty("cpf_cnpj", user.getCpf_cnpj()); 
    usr.addProperty("empresa", user.getEmpresa()); 
usr.addProperty("cargo", user.getCargo()); 

insertUser.addSoapObject(usr); 

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
envelope.setOutputSoapObject(insertUser); 

envelope.implicitTypes = true; 

HttpTransportSE http = new HttpTransportSE(URL); 
try { 

http.call("urn:" + INSERIR, envelope); 
SoapPrimitive resposta = (SoapPrimitive) envelope.getResponse(); 

return Boolean.parseBoolean(resposta.toString()); 

} catch (Exception e) { 
e.printStackTrace(); 
return false; 
} 
} 
}

我应该做的userDOA.java。 ASynctask看起来像这样。

 AsyncTask<String, Void, Boolean) task =new AsyncTask<String, Void, Boolean>() { 

     @Override 
     protected Boolean doInBackground(String... params) { 
      HttpTransportSE http = new HttpTransportSE(URL); 
      try { 

       http.call("urn:" + INSERIR, envelope); 
       SoapPrimitive resposta = (SoapPrimitive) envelope.getResponse(); 

       return Boolean.parseBoolean(resposta.toString()); 
      } catch (Exception e) { 
       //handle exception 
      } 
     } 

     @Override 
     protected void onPostExecute(Boolean result) { 
      //Do something with result 
     } 
    }

你需要调用它像

task.execute(params);

希望这有助于。
