我收到一条错误消息，指出“SharedPreferences类型中的方法getLong（String，long）不适用于参数（字符串）“在线（一路在我的代码的末尾）：SharedPreferences类型中的方法getLong（String，long）不适用于参数（字符串）
long oldTime = pref.getLong("smstimestamp");
但是我不知道如何解决这个问题。
有什么建议吗？

，请参阅Java API：http://developer.android.com/reference/android/content/SharedPreferences.html#getLong(java.lang .String，long）它应该接受**两个**参数。 **正如编译器告诉你的那样。通过** 0 **作为第二个参数。 – Maroun
