``public class DatabaseHelper扩展了SQLiteOpenHelper {

Answer 1

   public void AddFeedback(String gname, String add, String mail,
        String phn, String sugg, String gre) {
    // TODO Auto-generated method stub
     SQLiteDatabase db = this.getWritableDatabase();
     ContentValues cv = new ContentValues();

     cv.put(colguestname,gname);
     cv.put(coladdress, add);
     cv.put(colphone, phn);
     cv.put(colemail, mail);
     cv.put(colsuggestion, sugg);
     cv.put(colgrievances,gre);
     db.insert(feedbacktable, null, cv);
     db.close();
}

Answer 2

检查表的结构。根据我在表结构中的知识，您可以使用约束，如外键，整数，varchar（15）等。在插入时，您的查询不满足该约束。因此，请检查表结构和SQL查询。

插入SQLite时出错
