android - SubscriptionManager.from() 已弃用

Question

以前我们用来获取SubscriptionManagerusing的实例

SubscriptionManager subscriptionManager=SubscriptionManager.from(this);

但SubscriptionManager.from(context)在 API 28 中已弃用，获取SubscriptionManager实例的新方法是什么？

Answer 1

SubscriptionManager我们可以通过以下方式获得实例

爪哇

 SubscriptionManager subscriptionManager= (SubscriptionManager) getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);

或者

SubscriptionManager subscriptionManager=getSystemService(SubscriptionManager.class);

对于 API>=23

科特林

val subscriptionManager = getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE) as SubscriptionManager

或者

var subscriptionManager = getSystemService(SubscriptionManager::class.java)
