我正在使用webservices从另一个表中获取数据。我正在跟踪表的每个值，所以我确定我正在获取值，但我无法将它们插入到我的新表中。我无法到达我去了，任何人都会帮帮我..
我正在使用的代码是
private void insertData(String bbookId,String bdesc, byte[] image1,byte[] image2 ,String bid,String bname) {
Log.i("id",bid);
Log.i("BookId",bbookId);
Log.i("name",bname);
System.err.println("url1"+image1);
System.err.println("url2"+image2);
System.err.println("desc"+bdesc);
Log.e("testing","LOOK @ 1214353469TRJB UJIOY ");
SQLiteDatabase db = placeData.getWritableDatabase();
Log.i("Bookid",bbookId);
ContentValues values;
values = new ContentValues();
values.put("bbookid",bbookId);
values.put("desc",bdesc);
values.put("url1",image1);
values.put("url2",image2);
values.put("bid",bid);
values.put("name", bname);
Log.i("inserting","______________");
db.insert("pagess", null, values);
}
我成功获取所有日志值，并且还显示日志标记“插入” _

答案 0 :(得分：4)
删除
values.put("bid",bid);来自插入语句值。
由于bid 自动递增主键。
再试一次..
<强>更新
来自PlaceData Database class。
KEY_ID+" INTEGER PRIMARY KEY AUTOINCREMENT
private static final String KEY_ID="bid";
因此您无需插入bid主键。您的Sqlite表会自动生成（递增）它。对于每个新插入的记录。
答案 1 :(得分：1)
请勿尝试设置出价，因为它已经是自动增值。
删除此 values.put（“出价”，出价）;
无需插入它，它违反了主键约束。
答案 2 :(得分：0)
日志告诉你什么错！您的插入终止主键约束.check用于将重复值插入主键字段
android.database.sqlite.SQLiteConstraintException: PRIMARY KEY must be unique (code 19)
答案 3 :(得分：0)
错误本身告诉你错误的是什么：
android.database.sqlite.SQLiteConstraintException：PRIMARY KEY必须是 独特的（代码19）
您实际上不需要提供KEY_ID值。
答案 4 :(得分：0)
您创建了一个Primary Key的表格。因此，其值必须为unique而不是NULL。所以当你第一次跑步时它可以正常工作。但第二次它采用相同的值，因此它不符合约束要求。
