                    } else {
                        Toast.makeText(getApplicationContext(), "الرجاء قيول لائحة النظم", Toast.LENGTH_SHORT).show();
                    }
                } else {
                    Toast.makeText(getApplicationContext(), "password does not match", Toast.LENGTH_SHORT).show();
                }
            } else {
                Toast.makeText(getApplicationContext(), "password is not strong", Toast.LENGTH_SHORT).show();
            }
        }
    });



}

by the way, the return statement in the parse Network method has a compiler error here is the respond

                     {
                     "tblRegisteredUsers_UserPKID": 3034,
                         "tblRegisteredUsers_UserName": "hi21323",

any help would be appreciated

If you have a specific Object/Structure of your Json you might want to implement a MyStructureObject.class somewhere and add all those variables to it.

MyStructureObject{
String id;
   public String getIdField(){
      return id;
   }
... // add all other variables of your json structure
}

Than you can use a JSON library like com.google.code.gson (from maven gradle repository) and serialize (or deserialize) a JsonObject from your JsonString.

MySturctureObject instance = new Gson().fromJson(yourJsonString,MyStructureObject.class);
String id = instance.getIdField();

I hope this helps a little :) I already added gson library in my own android java/libgdx application successfully, but maybe you want to use another library instead. It's just a suggestion.
