class 上未找到 setter/field,但变量名称正确
No setter/field found on class but variable names are correct
我正在尝试使用 Firebase 实时数据库实施星级评分系统,但出现以下错误:
No setter/field for rating found on class com.andrea.uncut.ui.Model.Post
我知道当变量的名称与数据库中的名称不同时会发生这种情况,但在这种情况下它们是:
public class Post {
private String postID;
private String postImage;
private float rating;
private String title;
private String description;
private String publisher;
public Post(String postID, String postImage, float rating, String title, String description, String publisher) {
this.postID = postID;
this.postImage = postImage;
this.rating = rating;
this.title = title;
this.description = description;
this.publisher = publisher;
}
public Post() {
}
public String getPostid() {
return postID;
}
public void setPostid(String postID) {
this.postID = postID;
}
public String getPostImage() {
return postImage;
}
public void setPostImage(String postImage) {
this.postImage = postImage;
}
public float getRatingScore() { return rating; }
public void setRatingScore(float rating) {
this.rating = rating;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getPublisher() {
return publisher;
}
public void setPublisher(String publisher) {
this.publisher = publisher;
}
}
所有其他变量都工作正常,所以它是否与 float 类型有关?
getRatingScore
和 setRatingScore
将用于名为 ratingScore
的 属性。
您的 属性 称为 rating
,因此需要 getRating
和 setRating
。
私有内部属性与 Firebase 在模型上设置数据时如何看待它们无关 class。
另外,为了保持一致性,postID
应该是 getPostID
和 setPostID
。
