你可以使用registerForActivityResult来代替startActivityForResult。下面是我在Kotlin中从图库中获取图片的代码：

// class level
private val openGallery =
        registerForActivityResult(ActivityResultContracts.StartActivityForResult()) {
            if (it.resultCode == RESULT_OK) {
                binding.imgProfile.load(it.data?.data)
            }
        }

// in onViewCreated
imgProfile.setOnClickListener {
            val intent = Intent(Intent.ACTION_PICK)
            intent.setType("image/*")
            intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)
            openGallery.launch(intent)
        }

//在按钮上侦听器放置此代码

buttonPressed.setOnClickListener {
                val intent = Intent(Intent.ACTION_PICK)
                intent.type = "image/*"
                intent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
                openGallery.launch(intent)            
        }

//在onCreate外部放置此代码

private val openGallery =     registerForActivityResult(ActivityResultContracts.StartActivityForResult()) {
            if (it.resultCode == RESULT_OK) {
                backgroundImage.setImageURI(it.data?.data)
            }
        }
