Answer 1

您可以使用同伴对象

• 类内部的对象声明可以用companion关键字标记:

试试这条路

class Keys {

    companion object {
        const val SPLASH_DURATION : Long = 5000
        const val READ_TIMEOUT : Int = 200
        const val CONNECTION_TIMEOUT : Int = 200
        const val WRITE_TIMEOUT : Int = 200

    }
}

Keys.CONNECTION_TIMEOUT;

object Keys {
    const val SPLASH_DURATION: Long = 5000
    const val READ_TIMEOUT: Int = 200
    const val CONNECTION_TIMEOUT: Int = 200
    const val WRITE_TIMEOUT: Int = 200
}

Keys.SPLASH_DURATION;
