我正在尝试使用以下代码从android中的SQLite数据库获取所有数据。运行它时,它崩溃并给我这个异常->
java.lang.IllegalStateException: Couldn't read row 0, col 0 from CursorWindow. Make sure the Cursor is initialized correctly before accessing data from it.
SQLiteDatabase db = this.getReadableDatabase();
Cursor c = db.rawQuery("SELECT * FROM " + menuItemTable,null);
if(c.moveToFirst() && c != null){
do{
Log.d("Log->", c.getString(c.getColumnIndex(TitleField)));
}while(c.moveToNext());
}
db.close();
有人可以帮我吗?谢谢!
其余的堆栈跟踪
