camera-在sd card中保存 image, audio和 video

在sd card中保存 image, audio和 video

如何在sd card中保存文件，在camera 類中創建了一個圖片，然後創建一個新的目錄來保存它。它創建了文件夾，但這個圖片為什麼不在文件夾中？

if (items[which].equals("Picture")) {

                            Intent cameraIntent = new Intent(
                                    MediaStore.ACTION_IMAGE_CAPTURE);
                            startActivityForResult(cameraIntent,
                                    PICTURE_ACTIVITY);

                            File imagesFolder = new File(Environment
                                    .getExternalStorageDirectory(),
                                    "SeccyPhotos");
                            imagesFolder.mkdirs(); // <----
                            File image = new File(imagesFolder, "image_001.jpg");
                            Uri uriSavedImage = Uri.fromFile(image);
                            cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                                    uriSavedImage);
                        }

我調用了camera類，這樣的話之後拍攝的照片就應該保存在文件夾中。
請問下：視頻和照相機相同嗎？

Intent cameraIntent = new Intent(
                                MediaStore.ACTION_VIDEO_CAPTURE);
                        startActivityForResult(cameraIntent,
                                PICTURE_ACTIVITY);

                        File videosFolder = new File(Environment
                                .getExternalStorageDirectory(),
                                "cangryVideos");
                        videosFolder.mkdirs(); // <----
                        File video = new File(videosFolder, "Video_001.3gp");
                        Uri uriSavedvideo = Uri.fromFile(video);
                        cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT,
                                uriSavedvideo);
                        startActivityForResult(cameraIntent,
                                PICTURE_ACTIVITY);

File f = null;

            try {
                f = setUpPhotoFile(); //setUpPhotoFile() 產生一個文件
                mCurrentPhotoPath = f.getAbsolutePath();
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
            } catch (IOException e) {
                e.printStackTrace();
                f = null;

            }
