我是第一次使用ionic-framework。我的任务是下一个，我想，当组件打开时，单选按钮应该默认选中。我想选中一个。提前感谢在此输入图像描述Screen imagefile typescripttools.component.html

I haven't really grasped the meaning of your component, but I would say that initializing your "radioList" variable to 0 should be sufficient.Also, it would be better to go by the id of your ColorValueObjInterface. it would give, in your .ts
radioList:number = colorValueObj[0]?.id || 0;
And your .html
... <ion-radio type="radio" [value]="item.id" name...></ion-radio> ...
And please, use the code sample btn to post your code
