Java 回收商查看无回收照片、姓名和状态，如何解决？

您好，我使用firebaserealtime通过查询实现了搜索，但现在它不显示姓名、照片或状态，执行搜索时会显示标准缩略图/配置文件，单击搜索的项目实际上就是源项目。我只是无法显示姓名、照片和状态数据。有人能帮我把onstart放进去，但没用。事先非常感谢。欢迎任何帮助。在实施之前，会显示照片、名称和状态。我做错了什么

调试中 getName或getStatus无返回数据：( 但是，如果我按用户名进行搜索，当我单击搜索时，单击事件中的搜索结果与搜索名称对应。是，它可以工作。问题->但它只是不显示照片、名称和状态

请编辑您的问题将您的数据库结构添加为JSON文件或至少一个屏幕截图。@Alex Mamo Hi感谢您的回答。如果您尝试记录

snapshot.child（“status”）.getValue（））。toString（）

是否在logcat中打印出来？是返回用户信息。名称、照片状态等…在

onBindViewHolder

方法中，返回什么

model.getName（）

？

public class Contacts {

    public String name, status, image;

    public Contacts(String name, String status)
    {

    }

    public Contacts(String name, String status, String image) {
        this.name = name;
        this.status = status;
        this.image = image;
    }

    public String getName() {
        return name;
    }

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

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public String getImage() {
        return image;
    }

    public void setImage(String image) {
        this.image = image;
    }
}
