德爾福Firemonkey的Android獲得通話記錄錯誤

你好，這是我的代碼：德爾福Firemonkey的Android獲得通話記錄錯誤

    TYPEXx:=JStringToString(cursor.getString(TYPEX)); 
    Result:=TYPEXx+CACHED_NAMEx+NUMBERx; 
    end; 
end;

，並使用... 這裏是使用方法

Memo1.lines.add（FetchCalls）;

但是，當我嘗試使用這個功能我得到這個錯誤：

「JAVA.LANG.LLLEGALSTATEEXCEPTION：無法讀取列0，-1 COL從CURSORWINDOW確保光標被正確初始化之前訪問。數據不是這樣。

任何想法如何解決這個問題??

非常感謝你

首先要檢查：您是否在應用清單中指定了READ_CALL_LOG權限？ – Deltics 2014-10-27 19:29:47

是的，權限是好的。 – 2014-10-27 19:33:32

另一個想法？非常感謝 – 2014-10-27 21:12:28

我解決你的問題，這是非常好的代碼誰我用來複制和固定完全相同的錯誤，您有。首先包括

Androidapi.JNI.Provider, FMX.Helpers.Android

根據你的delphi版本。在我的情況下，我使用Delphi 10.1柏林。

二取代所有

cursor.getColumnIndex(StringToJstring('XXXX'));

到

cursor.getColumnIndex(TJCallLog_Calls.JavaClass.XXXX);

爲例進行CACHED_NAME它將編譯一切後

CACHED_NAME:=cursor.getColumnIndex(TJCallLog_Calls.JavaClass.CACHED_NAME);

，它的工作就好了。我會給你的另一個建議是評論或刪除你提取的數據但你不使用。在代碼結束時，您只返回TYPE，CACHED_NAME和NUMER。從其他字段獲取數據的所有其他調用都是不必要的。
