如何为 Realm 中的字段设置默认值？

Question

我们如何为领域模型字段提供默认值？

例子 ：

class Demo extends RealmObject{
    private String id; // I want to set this id to a uuid 
    private boolean isVisibile; // set this to default as true              
}

Answer 1

class Demo extends RealmObject{
    public Demo() {
        id = UUID.randomUUID().toString();
        isVisible = true;
    } 

    @PrimaryKey
    private String id; // I want to set this id to a uuid 
    private boolean isVisibile; // set this to default as true              
}
