在kotlin中访问私有变量的onRestoreInstanceState

class MainActivity : AppCompatActivity() {
    private var myPrivateVariable: String = "Hello"

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }

    override fun onRestoreInstanceState(savedInstanceState: Bundle) {
        super.onRestoreInstanceState(savedInstanceState)
        myPrivateVariable = savedInstanceState.getString("myPrivateVariable") ?: ""
        // 在这里可以访问和修改私有变量myPrivateVariable
    }

    override fun onSaveInstanceState(outState: Bundle) {
        super.onSaveInstanceState(outState)
        outState.putString("myPrivateVariable", myPrivateVariable)
        // 在这里保存私有变量myPrivateVariable的值
    }
}
