我有点困惑 - 我得到了额外的东西:

Bundle extras = intent.getExtras();

然后我使用这些附加功能:

String mdn = extras.getString(DataCountUtilities.swappedMdn);

但我得到:

swappedMdn cannot be resolved or is not a field



Any suggestions?

您的代码是:-

    String mdn = extras.getString(DataCountUtilities.swappedMdn);

这是错误的。作为swappedmdn一种方法。做这样的事情: -

    String mdn = extras.getString(DataCountUtilities.swappedMdn(Context context));
