私はいくつかのAndroid / CM9学習を行っており、次の目的でストックアプリの1つからいくつかの機能を分離しようとしています:
- 仕組みを理解する
- 小さな変更を加えます。
この場合、連絡先からの最近の通話リストを使用することを学んでいます。ストックアプリと同じようにフィールドを使用しようとしていますCalls.COUNTRY_ISOが、Eclipseは「COUNTRY_ISOを解決できないか、フィールドではありません」と主張しています。これは、@hide 属性を使用して SDK から隠されているため、フィールドが実際に存在することも知っています。
私の文字列配列の宣言:
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
};
Eclipse にこのエラーを無視させ (この配列でのみ推奨)、とにかくコンパイルさせることはできますか?
フル クラスは、ファイル CallLog.java の android.provider.calllog.Calls です。
