NumberFormatException:无效的int:""

Question

在我的应用程序中,我正在进行语言本地化.它与按钮和texviews完美配合,但无法更改recyclerview上的字符串

它说 NumberFormatException:无效的int:""

  private void updateViews(String languageCode) {
                Context context = LocaleHelper.setLocale(MainActivity.this, languageCode);
                Resources resources = context.getResources();
                changelang.setText(resources.getString(R.string.changelanguage));
                languagename.setText(resources.getString(R.string.languagename));
 //error with following line                  object01.setDepname(Integer.parseInt(resources.getString(R.string.cultivation)));

            }
        });

堆栈跟踪

您正在尝试将资源中的字符串转换为整数值.这是不可能的!要支持多种语言,请使用所需的语言环境创建新的string.xml.
