LiveData是抽象的android [英] LiveData is abstract android

问题描述

我尝试初始化LiveData对象，但出现错误:"LiveData是抽象的，无法实例化"

I tried initializing my LiveData object and it gives the error: "LiveData is abstract, It cannot be instantiated"

LiveData列表LiveData = new LiveData<>();

LiveData listLiveData = new LiveData<>();

推荐答案

由于它是抽象的(如@CommonsWare说的那样)，您需要将其扩展到子类，然后按以下形式重写所需的方法:

Since it is abstract (as @CommonsWare says) you need to extend it to a subclass and then override the methods as required in the form:

public class LiveDataSubClass extends LiveData<Location> {

}
