如何在Android中不初始化的情况下使用某些变量

val myVariable: SomeClass by lazy {
    // 初始化代码
    SomeClass()
}

lateinit var myVariable: SomeClass

fun initialize() {
    myVariable = SomeClass()
}

import java.util.Optional;

Optional<SomeClass> myVariable = Optional.empty();

// 在需要的时候初始化
myVariable = Optional.of(new SomeClass());

val myVariable: Optional<SomeClass> = Optional.empty()

// 在需要的时候初始化
myVariable = Optional.of(SomeClass())

var myVariable: SomeClass? = null

// 在需要的时候初始化
myVariable = SomeClass()

// 安全地访问变量
myVariable?.doSomething()

class MyClass {
    lateinit var myVariable: SomeClass

    fun initialize() {
        myVariable = SomeClass()
    }

    fun useVariable() {
        if (::myVariable.isInitialized) {
            myVariable.doSomething()
        } else {
            throw UninitializedPropertyAccessException("myVariable has not been initialized")
        }
    }
}
