Android AsyncTask问题（连接到Web服务） _AsyncTask

【Android AsyncTask问题（连接到Web服务）】不飞则已，一飞冲天；不鸣则已，一鸣惊人。这篇文章主要讲述Android AsyncTask问题（连接到Web服务）相关的知识，希望能为你提供帮助。
所以我正在开发应用程序的登录活动，我想使用AsynTask连接到（SOAP）Web服务，我将向Web服务发送一个密钥，用户名和密码，这将给我一个布尔结果，无论是用户是否有效....在尝试AsyncTask之前，我使用的是我在网上找到的方法，你创建一个-caller类 - 扩展-Thread类 - 并在-MainActivity中使用while循环 - 这使得-UI成为-UI线程睡眠 - 好吧它工作但它感觉有点不正确的方法，所以我调查它并发现AsyncTask但我似乎无法让它工作... PS：我不能分享网络服务的网址，因为它属于我的大学，对不起。

public class LoginActivity extends AppCompatActivity {Button loginButton; EditText usernumber,password; boolean result; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_login); getSupportActionBar().hide(); loginButton = (Button) findViewById(R.id.loginButton); usernumber = (EditText) findViewById(R.id.userNum); password = (EditText) findViewById(R.id.userPass); loginButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { try { new CallLoginWS().execute(); if(result == true){ Intent bEmpIntent = new Intent(LoginActivity.this,BasicEmployeeActivity.class); startActivity(bEmpIntent); }else{ Toast.makeText(LoginActivity.this,"username or password incorrect",Toast.LENGTH_SHORT).show(); } } catch (Exception e) { e.printStackTrace(); }} }); }public class CallLoginWS extends AsyncTask< Void,Void,Void> {private final String SOAP_ACTION = ""; private final String OPERATION_NAME = "IsValidUser"; private final String WSDL_TARGET_NAMESPACE = ""; private final String HOST = ""; private final String FILE = ""; private final String KEY = ""; @Override protected Void doInBackground(Void... voids) { SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,OPERATION_NAME); PropertyInfo pi=new PropertyInfo(); pi.setName("usagekey"); pi.setValue(KEY); pi.setType(String.class); request.addProperty(pi); pi = new PropertyInfo(); pi.setName("username"); pi.setValue(usernumber.getText().toString()); pi.setType(String.class); request.addProperty(pi); pi = new PropertyInfo(); pi.setName("password"); pi.setValue(password.getText().toString()); pi.setType(String.class); request.addProperty(pi); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.dotNet = true; envelope.setOutputSoapObject(request); HttpsTransportSE httpsTransport = new HttpsTransportSE(HOST,443,FILE,15000); SSLConnection ssl = new SSLConnection(); ssl.allowAllSSL(); try { httpsTransport.call(SOAP_ACTION, envelope); result = (boolean)envelope.getResponse(); } catch (Exception exception) { exception.printStackTrace(); } return null; } }

}
我是新手，我现在真的输了，所以任何帮助/建议都非常感谢。
答案您需要移动此代码

if(result == true){ Intent bEmpIntent = new Intent(LoginActivity.this,BasicEmployeeActivity.class); startActivity(bEmpIntent); }else{ Toast.makeText(LoginActivity.this,"username or password incorrect",Toast.LENGTH_SHORT).show(); }
