无法反序列化对象。无法将 java.lang.String 类型的值转换为 long

Question

我想从 firebase 中提取数据我有两个 digit 类型的字段，这会导致兼容性问题

除数字以外的其他字符数据都有效

package fr.halas.loginhalas.Filter;

import com.google.firebase.firestore.IgnoreExtraProperties;

@IgnoreExtraProperties
public class Affichage {


    public static final String FIELD_CREATOR_NAME = "CreatorName";
    public static final String FIELD_USERID = "UserID";
    public static final String FIELD_MODULE = "Module";
    public static final String FIELD_SECTION = "Section";
    public static final String FIELD_GROUPE = "Groupe";


    private String CreatorName;
    private String Module;
    private String UserID;
    private long Section;
    private long Groupe;



    public Affichage(String CreatorName,String UserID,String Module, long Section, long Groupe) {
        this.CreatorName = CreatorName;
        this.UserID = UserID;
        this.Module = Module;
        this.Section = Section;
        this.Groupe = Groupe;
    }

    public Affichage() {
        // empty default constructor, necessary for Firebase to be able to deserialize users
    }

    public String getCreatorName() {
        return CreatorName;
    }

    public void setCreatorName(String creatorName) {
        CreatorName = creatorName;
    }

    public String getModule() {
        return Module;
    }

    public void setModule(String module) {
        Module = module;
    }

    public String getUserID() {
        return UserID;
    }

    public void setUserID(String userID) {
        UserID = userID;
    }

    public long getSection() {
        return Section;
    }

    public void setSection(long section) {
        Section = section;
    }

    public long getGroupe() {
        return Groupe;
    }

    public void setGroupe(long groupe) {
        Groupe = groupe;
    }


}

  @SuppressLint("SetTextI18n")
        public void bind(final DocumentSnapshot snapshot, final OnAffichageSelectedListener listener) {

            final Affichage affichage = snapshot.toObject(Affichage.class); // Error is here ! 

            creator.setText(affichage.getCreatorName());
            moduleView.setText(affichage.getModule());
            groupeView.setText("Groupe: " + affichage.getGroupe());
            sectionView.setText("Section: " + affichage.getSection());

错误信息是 05-10 18:00:36.850 19488-19488/fr.halas.loginhalas E/AndroidRuntime: 致命异常: main 进程：fr.halas.loginhalas，PID：19488 java.lang.RuntimeException：无法反序列化对象。无法将 java.lang.String 类型的值转换为 long（在字段 'Groupe' 中找到）

Answer 1

在我的手机上完全删除应用程序并重新启动编译后正常启动而没有错误，应用程序必须提供无效缓存

Answer 2

这两行：

    groupeView.setText("Groupe: " + affichage.getGroupe());
    sectionView.setText("Section: " + affichage.getSection());

应该是：

    groupeView.setText("Groupe: " + Long.toString(affichage.getGroupe());
    sectionView.setText("Section: " + Long.toString(affichage.getSection());
