我正在做一些 android/CM9 学习，并试图从其中一个库存应用程序中分离出一些功能，以便:
- 了解它是如何工作的
- 做一个小改动。
在这种情况下，我正在学习使用联系人的最近通话 list 。我正在尝试使用字段 Calls.COUNTRY_ISO，与股票应用程序相同，但 Eclipse 坚持“COUNTRY_ISO 无法解析或不是字段”。我知道这一点是因为它通过 @hide 属性从 SDK 中隐藏起来，因此也知道该字段确实存在。
我的字符串数组的声明:
import android.provider.CallLog.Calls
public static final String[] _PROJECTION = new String[] {
Calls._ID, // 0
Calls.NUMBER, // 1
Calls.DATE, // 2
Calls.DURATION, // 3
Calls.TYPE, // 4
Calls.COUNTRY_ISO, // 5
Calls.VOICEMAIL_URI, // 6
Calls.GEOCODED_LOCATION, // 7
Calls.CACHED_NAME, // 8
Calls.CACHED_NUMBER_TYPE, // 9
Calls.CACHED_NUMBER_LABEL, // 10
Calls.CACHED_LOOKUP_URI, // 11
Calls.CACHED_MATCHED_NUMBER, // 12
Calls.CACHED_NORMALIZED_NUMBER, // 13
Calls.CACHED_PHOTO_ID, // 14
Calls.CACHED_FORMATTED_NUMBER, // 15
Calls.IS_READ, // 16
};
是否可以强制 Eclipse 忽略此错误(最好仅在此数组上)并继续编译？
完整类是文件 CallLog.java 中的 android.provider.calllog.Calls

最佳答案
标有@hide 注释的字段似乎是受限制的，类似于普通Java 运行时中的sun.* 包。尝试访问这些值通常被认为是一个坏主意。为什么需要访问它们？
