Question

我对java librairie OpenCSV有疑问。我没有成功读取我的CSV文件的所有行，我只读了第二行，我不知道为什么......

我的CSV文件：

    "NumACLEB","Nom","Prenom","Niveau","Telephone","Portable","Rue","Code Postale","Ville","Activite","Adresse Mail","Cotisation Acleb","Cotisation Adherent"
"0","Pierre","Paul","Jacques","0585987445","0187458596","tests","92569","PARIS","POKER","test@test.fr","14","11"
"0","Julie","Julie","Beginner","0878589632","1445856996","test3","93857","PAris","POKER","foo@foo.fr","14","11"

我使用OpenCSV创建一个Android列表，只有“Julie”“Julie”这一行被添加3次......

try
        {
            CSVReader csvReader = new CSVReader(new FileReader(SettingsActivity.SaveFolder+"PDF/Liste_Membres.csv"),'\t');
            //List<String[]> content = csvReader.readAll();
            String[] row = csvReader.readNext();
            while(row != null) 
            {
                if(row[1]!="Nom")
                {
                    map.put("viewname", row[1]+"  "+row[2]);
                    map.put("viewDetails", "Ville : "+row[8]+" Cotisation ACLEB : "+row[11]+"€ Cotisation poker : "+row[12]+"€");
                    map.put("img", String.valueOf(R.drawable.aclebapc_logo));
                    listItem.add(map);
                }else
                {
                    map.put("viewname", "NOM    Prenom");
                    map.put("viewDetails", "Ville   -  Cotisation ACLEB   -    Cotisation poker");
                    map.put("img", String.valueOf(R.drawable.aclebapc_logo));
                    listItem.add(map);
                }
                row = csvReader.readNext();
            }
        }catch(IOException ex)
        {
            Context context = getApplicationContext();
            CharSequence text = "Erreur lors de l'ouverture du fichier CSV...";
            int duration = Toast.LENGTH_SHORT;
            Toast toast = Toast.makeText(context, text, duration);
            toast.show();
        }

Answer 1

我认为map是某种词典？当您将值一遍又一遍地放在相同的键中时，它会覆盖之前的值。

我建议根据您尝试解决的问题采用不同的数据结构。

Answer 2

Beautifulcoder击中了头部。您正在为地图中插入的每个值使用相同的键，因此您将覆盖所有内容，并且只会看到您在地图中放置的最后一个项目
