我有 VisitingCardPOJO 表格。我想更新单个条目说在哪里 no=3

VisitingCardPOJO.java

   @PrimaryKey private int no;
    private String name;
    private String address;

    public int getNo() {
        return no;
    }

    public void setNo(int no) {
        this.no = no;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {

我找到了解决方案并且它有效

 public void updateNewCard(Realm realm, VisitingCardPOJO card) {
        realm.beginTransaction();
        VisitingCardPOJO toEdit = realm.where(VisitingCardPOJO.class)
                .equalTo("no", card.getNo()).findFirst();
        toEdit.setName(card.getName());
        toEdit.setAddress(card.getAddress());
        realm.commitTransaction();
    }
