android把数字转换成字符串,如何在roomandroid中使用typeconverter将整数转换为字符串?...

我正在开发一个聊天应用程序,但我得到以下错误:找不到字段的getter。

这就是为什么我想在房间里用类型转换器把整数转换成字符串,但我在下面找不到任何示例用户.java模型类

@Entity public class User implements IChatUser {

@PrimaryKey(autoGenerate = true)

private Integer id;

@ColumnInfo(name = "name")

private String name;

@Ignore

Bitmap icon;

public User() {

}

@Ignore

public User(String name, Bitmap icon) {

this.name = name;

this.icon = icon;

}

@Override

public Integer getId() {

return this.id;

}

@Override

public String getName() {

return this.name;

}

public void setId(Integer id) {

this.id = id;

}

public void setName(String name) {

this.name = name;

}

@Override

public Bitmap getIcon() {

return this.icon;

}

@Override

public void setIcon(Bitmap icon) {

this.icon = icon;

} }

下面伊查图瑟.kt

interface IChatUser {

fun getId(): String

fun getName(): String?

fun getIcon(): Bitmap?

fun setIcon(bmp: Bitmap)

}
