Kotlin View setEnabled函数丢失? [英] Kotlin View setEnabled function missing?

问题描述

在科特林中，当使用kotlinx.android.synthetic访问View(例如Button)时，缺少setEnabled()功能吗? isEnabled()功能仍然存在.

In Kotlin, when using kotlinx.android.synthetic to access the View (e.g. Button), the setEnabled() function is missing? The isEnabled() function is still there.

我怎么setEnabled()?

推荐答案

如所述在参考文献中，使用以下逻辑，将Java getter和getter和setter对在属性中表示为Kotlin:

As said in the reference, Java getters and pairs of getter and setter are represented as properties in Kotlin, using the following logic:

• T getSomething()(+ void setSomething(T))→something: T
• T isSomething()(+ void setSomething(T))→isSomething: T

• T getSomething() (+ void setSomething(T)) → something: T
• T isSomething() (+ void setSomething(T)) → isSomething: T

如果有塞特犬，从Kotlin可以看到var-属性，否则它是不可修改的val.

If there is a setter, a var-property is seen from Kotlin, otherwise it's an unmodifiable val.

使用isEnabled = value代替setEnabled(value).
