如果您正在使用SMS同意API，则使用以下代码(Kotlin):

resultLauncher.launch( consentIntent
                            )

    var resultLauncher = registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->
    if (result.resultCode == Activity.RESULT_OK) {
        // There are no request codes
    //    val data: Intent? = result.data
        val message = result.data?.getStringExtra(SmsRetriever.EXTRA_SMS_MESSAGE)
        getOtpFromMessage(message)

    }
}

在Java 8中，它可以这样写:

ActivityResultLauncher<Intent> startActivityForResult = registerForActivityResult(
    new ActivityResultContracts.StartActivityForResult(),
    result -> {
        if (result.getResultCode() == AppCompatActivity.RESULT_OK) {
            Intent data = result.getData();
            // ...
        }
    }
);

Intent intent = new Intent( ... );
startActivityForResult.launch(intent);

另一种方法是分3步完成。(考虑到你有一个startActivityForResult(0和onActivityResult()))

创建一个形式为var resultLauncher的变量:ActivityResultLauncher<Intent> 创建一个私有函数，在其中以这种基本格式初始化resultLauncher

resultLauncher=registerForActivityResult(ActivityResultContracts.StartActivityForResult()){result ->  

// copy paste the code from the onActivityResult replacing resultcode to result.resultCode  

if(result.resultcode==Activity.Result_OK){
val data=result.data // this data variable is of type intent and you can use it 

}else{
//code if you do not get the data 
}
}

使用startActivityForResult()返回行，并将其替换为resultLauncher.launch(intent)

从现在开始，startActivityForResult()已经被弃用，所以使用new方法代替。

芬兰湾的科特林的例子

    fun openActivityForResult() {
        startForResult.launch(Intent(this, AnotherActivity::class.java))
    }


    val startForResult = registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { 
    result: ActivityResult ->
        if (result.resultCode == Activity.RESULT_OK) {
            val intent = result.data
            // Handle the Intent
            //do stuff here
        }
    }

似乎onActivityResult在超类中已弃用，但你在你的问题中没有提到超类名称和compileSdkVersion。

在Java和Kotlin中，只要添加@Deprecated，每个类或方法都可以标记为deprecated，所以检查你的超类，你可能扩展了一个错误的类。

当一个类被弃用时，它的所有方法也被弃用。

要看到一个快速的解决方案，点击弃用的方法，并按Ctrl+Q在Android工作室查看方法的文档，应该有一个解决方案。

在我使用androidx和API 29作为compileSdkVersion的项目中，此方法在活动和片段中不弃用

这就是我如何替换多个requestCodes(把这段代码放在你的活动中):

    ActivityResultLauncher<Intent> launchCameraActivity = registerForActivityResult(
        new ActivityResultContracts.StartActivityForResult(),
        new ActivityResultCallback<ActivityResult>() {
            @Override
            public void onActivityResult(ActivityResult result) {
                if (result.getResultCode() == Activity.RESULT_OK) {
                    Intent data = result.getData();
                    Bitmap photoBitmap;
                    if(data != null && data.getExtras() != null){
                        photoBitmap = (Bitmap) data.getExtras().get("data");
                        if (photoBitmap != null) {
                            dataModel.setPhoto(ImageUtil.convert(photoBitmap));
                            imageTaken.setVisibility(View.VISIBLE);
                            imageTaken.setImageBitmap(photoBitmap);
                        }

                    }
                }
            }
        });

ActivityResultLauncher<Intent> launchCameraAndGalleryActivity = registerForActivityResult(
    new ActivityResultContracts.StartActivityForResult(),
    new ActivityResultCallback<ActivityResult>() {
        @Override
        public void onActivityResult(ActivityResult result) {
            if (result.getResultCode() == Activity.RESULT_OK) {
                
                Intent data = result.getData();
                Uri imageUri;
                if (data != null) {
                    imageUri = data.getData();
                    InputStream imageStream;
                    try {
                        imageStream = getContentResolver().openInputStream(imageUri);
                        Bitmap photoBitmap = BitmapFactory.decodeStream(imageStream);
                        dataModel.setOtherImage(ImageUtil.convert(photoBitmap));
                        documentImageTaken.setVisibility(View.VISIBLE);
                        documentImageTaken.setImageBitmap(photoBitmap);
                    }catch (FileNotFoundException e) {
                        e.printStackTrace();
                    }
                }
            }
        }
    });

我是这样开展活动的:

                    Intent photoIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                launchCameraAndGalleryActivity.launch(photoIntent );

Intent galleryIntent= new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    launchCameraActivity.launch(galleryIntent);
