onActivityResult 不返回在物理设备上运行的 Intent

Question

当使用相机 Intent 从我的 android 模拟器拍摄视频时，onActivityResult 返回了我的视频录制的 Intent。但是如果我从我的 moto g6 物理设备制作它，则 Intent 将返回 null（如某些图像所示. 我会插入我的代码给你一个更好的画面。

这是我的代码...

private void record() {
    Intent intent=new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
    if(intent.resolveActivity(getActivity().getPackageManager())!=null){
         new_video_file=getFilePath();
        Uri uri = FileProvider.getUriForFile(getActivity(),
                BuildConfig.APPLICATION_ID + ".provider",new_video_file);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
        startActivityForResult(intent,VIDEO_REQUEST);

    }
}

OnActivityForResult....

  @Override
public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == VIDEO_REQUEST && resultCode == RESULT_OK) {
        ParseQuery<ParseObject> query = ParseQuery.getQuery("CitaTestDrive");
        query.getInBackground(idEventoTestDrive, new GetCallback<ParseObject>() {
            @Override
            public void done(ParseObject object, ParseException e) {
                videoUri = data.getData();
                String file = videoUri.getPath();
                File inputFile = new File(file);

                try {
                    fileInputStream = new FileInputStream(inputFile);
                } catch (FileNotFoundException ex) {
                    ex.printStackTrace();
                }
                Bitmap thumbnailBm = BitmapFactory.decodeStream(fileInputStream);
                ByteArrayOutputStream st = new ByteArrayOutputStream();
                thumbnailBm.compress(Bitmap.CompressFormat.JPEG, 50, st);
                byte[] byteArr = st.toByteArray();
                Date currentTime = Calendar.getInstance().getTime();

                ParseFile thumbFile = new ParseFile("TestDrive" + " " + currentTime + " " + nombreAsesor + ".jpg", byteArr);
                object.put("Video", thumbFile);
                object.saveInBackground(new SaveCallback() {
                    @Override
                    public void done(ParseException e) {
                        if (e == null) {
                            Toast.makeText(getActivity(), "Video uploaded to server", Toast.LENGTH_LONG).show();
                        } else {
                            Toast.makeText(getActivity(), e.toString(), Toast.LENGTH_LONG).show();
                        }
                    }
                });

获取文件路径方法....

 private File getFilePath() {
    File folder = new File(getActivity().getExternalFilesDir(null), "test_drives");
    if (!folder.exists()) {
        folder.mkdir();
    }

    Date currentTime = Calendar.getInstance().getTime();

    video_file = new File(folder, "test_drives_" + currentTime + ".mp4");
    return video_file;
}

更新----- 我按照你的建议来获取uri路径。和....

还要锁定我是如何获得路径的

Answer 1

private fun getRealPathFromURI(contentURI: Uri): String? {
val result: String?
val cursor = contentResolver.query(contentURI, null, null, null, null)
if (cursor == null) { // Source is Dropbox or other similar local file path
    result = contentURI.path
} else {
    cursor.moveToFirst()
    val idx = cursor.getColumnIndex(MediaStore.Images.Media.DATA)
    result = cursor.getString(idx)
    cursor.close()
}
return result
}

val file: File = File(getRealPathFromURI(Uri.parse(imagePath)))

试试这个以获得文件的真实路径

就我而言，我使用了 EasyImagePicker 库。从图库或文件资源管理器中选择图片或视频或任何其他文档非常容易使用。下面是实现：

实现'com.github.jkwiecien:EasyImage:2.1.1'

您可以从以下链接查看实施步骤：

https://github.com/jkwiecien/EasyImage

确保您必须从用户那里获得权限或在清单文件中设置权限。

EasyImage.openChooserWithGallery(DoctorRegisterLastActivity.this,"Select Video", 1);

下面是onActivityResult的代码：

@Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        EasyImage.handleActivityResult(requestCode, resultCode, data, DoctorRegisterLastActivity.this, new DefaultCallback() {
            @Override
            public void onImagePickerError(Exception e, EasyImage.ImageSource source, int type) {
            }

            @Override
            public void onImagesPicked(@NonNull List<File> imageFiles, EasyImage.ImageSource source, int type) {
                if (!imageFiles.isEmpty()) {
                    if (type == 1) {

                       Glide.with(mContext)
                            .load(imageFiles.get(0).getPath())
                            .diskCacheStrategy(DiskCacheStrategy.ALL)
                            .placeholder(R.drawable.ic_logo_green)
                            .into(iv_featured_cover);

                    }
                }
            }

            @Override
            public void onCanceled(EasyImage.ImageSource source, int type) {
                if (source == EasyImage.ImageSource.CAMERA_IMAGE) {
                    File photoFile = EasyImage.lastlyTakenButCanceledPhoto(LastActivity.this);
                    if (photoFile != null) photoFile.delete();
                }
            }
        });
    }

替换为您的 OnActivityForResult 代码。

@Override
public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == VIDEO_REQUEST && resultCode == RESULT_OK) {
        ParseQuery<ParseObject> query = ParseQuery.getQuery("CitaTestDrive");
        query.getInBackground(idEventoTestDrive, new GetCallback<ParseObject>() {
            @Override
            public void done(ParseObject object, ParseException e) {
                videoUri = data.getData();
                String file = videoUri.getPath();
                File inputFile = new File(file);

                try {
                    fileInputStream = new FileInputStream(inputFile);
                } catch (FileNotFoundException ex) {
                    ex.printStackTrace();
                }
                Bitmap thumbnailBm = BitmapFactory.decodeStream(fileInputStream);
                ByteArrayOutputStream st = new ByteArrayOutputStream();
                thumbnailBm.compress(Bitmap.CompressFormat.JPEG, 50, st);
                byte[] byteArr = st.toByteArray();
                Date currentTime = Calendar.getInstance().getTime();

                ParseFile thumbFile = new ParseFile("TestDrive" + " " + currentTime + " " + nombreAsesor + ".jpg", byteArr);
                object.put("Video", thumbFile);
                object.saveInBackground(new SaveCallback() {
                    @Override
                    public void done(ParseException e) {
                        if (e == null) {
                            Toast.makeText(getActivity(), "Video uploaded to server", Toast.LENGTH_LONG).show();
                        } else {
                            Toast.makeText(getActivity(), e.toString(), Toast.LENGTH_LONG).show();
                        }
                    }
                });

试试这个代码，让我知道它是否有效。

首先，创建将存储视频原始数据的文件，然后使用该文件获取播放该视频的路径。

这是基本语法：

private static final int REQUEST_VIDEO_CAPTURE = 300;

private Uri videoUri;

private void dispatchVideoIntent(){
    Intent takeVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
    File outputFile = new File("your file path goes here");
    videoUri = FileProvider.getUriForFile(getActivity(),  
     BuildConfig.APPLICATION_ID + ".provider",new_video_file);
    takeVideoIntent.putExtra(MediaStore.EXTRA_OUTPUT, videoUri);
    if (takeVideoIntent.resolveActivity(getPackageManager()) != null) {
        startActivityForResult(takeVideoIntent, REQUEST_VIDEO_CAPTURE);
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_VIDEO_CAPTURE && resultCode == RESULT_OK && videoUri != null) {
            // do what you want with videoUri
    }
}
