POSTデータでVolleyを使用するとAndroidでエラーが発生する

Question

ログインwebsideフォームアプリケーションを作成しようとしていますので、wikiなどのログイン用websideにアプリを作成しようとしますが、ログイン時にPOSTユーザー名とパスワードをスタックします。

public class LoginActivity extends AppCompatActivity implements View.OnClickListener { 
    public static final String LOGIN_URL = "https://example.com/login"; 

    public static final String KEY_USERNAME = "email"; 
    public static final String KEY_PASSWORD = "password"; 
    private EditText editTextUsername; 
    private EditText editTextPassword; 
    private Button buttonLogin; 

    private String email; 
    private String password; 

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

     editTextUsername = (EditText) findViewById(R.id.editTextUsername); 
     editTextPassword = (EditText) findViewById(R.id.editTextPassword); 

     buttonLogin = (Button) findViewById(R.id.buttonLogin); 

     buttonLogin.setOnClickListener(this); 
    } 

    private void userLogin() { 
     email = editTextUsername.getText().toString().trim(); 
     password = editTextPassword.getText().toString().trim(); 
     StringRequest stringRequest = new StringRequest(Request.Method.POST, LOGIN_URL, 
       new Response.Listener<String>() { 
        @Override 
        public void onResponse(String response) { 



VolleyLog.v("Response:%n %s", response); 
        Log.d("PRINTOUT:%s",response); 
        WebView webview = new WebView(LoginActivity.this); 
        setContentView(webview); 
        webview.loadData(response, "text/html; charset=utf-8", "utf-8"); 
        } 
       }, 
       new Response.ErrorListener() { 
        @Override 
        public void onErrorResponse(VolleyError error) { 
         VolleyLog.e("Error: ", error.getMessage()); 
         Toast.makeText(LoginActivity.this, error.toString(), Toast.LENGTH_LONG).show(); 
        } 
       }) { 
      @Override 
      protected Map<String, String> getParams() throws AuthFailureError { 
       Map<String, String> map = new HashMap<String, String>(); 
       map.put(KEY_USERNAME, email); 
       map.put(KEY_PASSWORD, password); 
       return map; 
      } 
     }; 

     RequestQueue requestQueue = Volley.newRequestQueue(this); 
     requestQueue.add(stringRequest); 
    } 

    private void openProfile() { 
     Intent intent = new Intent(this, ActivityUserProfile.class); 
     intent.putExtra(KEY_USERNAME, email); 
     startActivity(intent); 
    } 

    @Override 
    public void onClick(View v) { 
     userLogin(); 
    } 
} 

が、私が間違って行う場所誰が言うことができる私はこの

ようlogcatを取得しますか？

Answer 1

Volley POSTが正常に動作します。あなたは、サーバーからの応答を受信して​​います

<script>window.location.href = '/login?from=' + encodeURIComponent(window.location.href);</script>

EDITED

問題はWebViewは、その応答を表示することができないということです。 WebViewのこの号のように見えます。trackerです。あなたが見ることができるように、ステータスは固定された2016年4月26日に変更されました。WebViewの更新後、これは動作するはずです/
