使用okhttp json登錄

Question

在這裏，我正在登錄頁面。當我寫入用戶名和移動到密碼edittext時，它應該檢查用戶名在json api中，無論是第一次登錄還是重複登錄....重複登錄時setvisible textview忘記密碼是setVisibView.visible，如果它是第一次將顯示getpassword textview。 這裏是我的代碼：

try { 
           JSONObject jsonObject = new JSONObject(res); 
           JSONArray result = jsonObject.getJSONArray(ConstantsValues.result); 
           JSONArray result1 = jsonObject.getJSONArray(ConstantsValues.result1); 

           for (int i = 0; i < result.length(); i++) { 
            JSONObject obj_result = result.getJSONObject(i); 
            String Success = obj_result.getString("SUCCESS"); 
            if (Success.equals("1")) { 
             for (int j = 0; j < result1.length(); j++) { 
              JSONObject obj_result1 = result1.getJSONObject(j); 
              String Message = obj_result1.getString("message"); 
              if (Message.equals("Forget Password.")) { 
               forgetpass.setVisibility(View.VISIBLE); 
              } else { 
               getpass.setVisibility(View.VISIBLE); 
              } 
             } 

            } else { 
             showAlertDialog("Invalid", "Invalid password or Email"); 
            } 


           } 
           runOnUiThread(new Runnable() { 
            @Override 
            public void run() { 
             // you can access all the UI componenet 

            } 
           }); 

這裏的錯誤是：

假設所有代碼都在後臺線程裏面，你看到的知名度代碼應該是內部runOnUiThread（）：

例如：

 if (Message.equals("Forget Password.")) { 
       runOnUiThread(new Runnable() { 
        @Override 
        public void run() { 
         forgetpass.setVisibility(View.VISIBLE); 
        } 
       }); 
     }
