adding in ImageView from Camera/Gallery in Fragment Android Sudio Kotlin

Question

I am beginner to android studio and just started learning Kotlin. I have a problem: I cannot add a picture from the camera or from the gallery to the ImageView in a fragment. Help me please:( I've seen examples with bitmap, but it doesn't work for Activity and Fragment. I inserted onActivityResult, but the photo from the camera did not appear in the imageView. I do not understand how to correctly link to the imageView. P.S. Sorry for my bad English:)

            savedInstanceState: Bundle?

        homeViewModel =

            intent.type = "image/*"
            startActivityForResult(intent, REQUEST_CODE)

        }


        

        // вызов камеры
        var btn: Button = root.findViewById(R.id.buttoncamera)

        btn.setOnClickListener {
            val bInt = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
            startActivityForResult(bInt, REQUEST_CODE)
        }

        return root

    }

        override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
            if (requestCode== REQUEST_CODE && requestCode == Activity.RESULT_OK){

                val image=data?.extras?.get("data") as Bitmap
                imageView.setImageBitmap(image)
            } else {
                super.onActivityResult(requestCode, resultCode, data)
            }

    }

Open Camera and take a picture method

 private void takeCameraImage() {
    Dexter.withActivity(this)
            .withPermissions(Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE)
            .withListener(new MultiplePermissionsListener() {
                @Override
                public void onPermissionsChecked(MultiplePermissionsReport report) {
                    if (report.areAllPermissionsGranted()) {
                        fileName = System.currentTimeMillis() + ".jpg";
                        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                        takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, getCacheImagePath(fileName));
                        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
                            startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
                        }
                    }
                }

                @Override
                public void onPermissionRationaleShouldBeShown(List<PermissionRequest> permissions, PermissionToken token) {
                    token.continuePermissionRequest();
                }
            }).check();
}

Open Gallery and take an image

private void chooseImageFromGallery() {
    Dexter.withActivity(this)
            .withPermissions(Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE)
            .withListener(new MultiplePermissionsListener() {
                @Override
                public void onPermissionsChecked(MultiplePermissionsReport report) {
                    if (report.areAllPermissionsGranted()) {
                        Intent pickPhoto = new Intent(Intent.ACTION_PICK,
                                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                        startActivityForResult(pickPhoto, REQUEST_GALLERY_IMAGE);
                    }
                }

                @Override
                public void onPermissionRationaleShouldBeShown(List<PermissionRequest> permissions, PermissionToken token) {
                    token.continuePermissionRequest();
                }
            }).check();

}

on activity method

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
        case REQUEST_IMAGE_CAPTURE:
            if (resultCode == RESULT_OK) {
                cropImage(getCacheImagePath(fileName));
            } else {
                setResultCancelled();
            }
            break;
        case REQUEST_GALLERY_IMAGE:
            if (resultCode == RESULT_OK) {
                Uri imageUri = data.getData();
                cropImage(imageUri);
            } else {
                setResultCancelled();
            }
            break;
        case UCrop.REQUEST_CROP:
            if (resultCode == RESULT_OK) {
                handleUCropResult(data);
            } else {
                setResultCancelled();
            }
            break;
        case UCrop.RESULT_ERROR:
            final Throwable cropError = UCrop.getError(data);
            Log.e(TAG, "Crop error: " + cropError);
            setResultCancelled();
            break;
        default:
            setResultCancelled();
    }
}

You can remove the crop function you want

Create a path (file for an image taken from a camera )

  private Uri getCacheImagePath(String fileName) {
    File path = new File(getExternalCacheDir(), "camera");
    if (!path.exists()) path.mkdirs();
    File image = new File(path, fileName);
    return getUriForFile(ImagePickerActivity.this, getPackageName() + ".provider", image);
}

In your manifest file

<provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths" />
    </provider>
