当我在我的sqlite中插入int
值时,它会一直说回false
这是我的onCreate
方法
@Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("create table PicTable(id INTEGER PRIMARY KEY AUTOINCREMENT,pic_key INTEGER)");
}
这是检查插入
的方法 public boolean insertPic (int pic){
SQLiteDatabase db = this.getWritableDatabase();
ContentValues contentValues = new ContentValues();
contentValues.put("pic_key",pic);
long result = db.insert("PicTable",null,contentValues);
if (result == -1)
return false;
else
return true;
}
当我输入int
值时,它会返回false
我的代码或其他内容是否有错误?
这是我的logcat
