Question

Java program that creates a photo album application.    Which will load a collection of images and displays them in a album layout. The program will allow the user to tag images with metadata:

•Title for the photo

.      Limited to 100 characters.

•Description for the photo

. Limited to 300 characters.

•Date taken

•Place taken

Functional Specs

1.Your album should be able to display the pictures sorted by Title, Date, and Place.

2.When the user clicks on a photo, data should be displayed.

3.The user should be able to add or remove pics.

*Please note the swing library cannot be used only scene (vBox,hBox, etc...)

*This is what I have so far - I can display and select images but Im not sure how to apply the buttons to remove, add, and add data (title, date, place) Please help, thank you.

Answer 1

CODE :

       @Override

       public void onClick(View arg0) {
        switch (arg0.getId()){

        break;
        case R.id.capture_dp:
        final Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, setImageUri());
        startActivityForResult(intent, TAKE_PHOTO_CODE);
        break;
        case R.id.add_galery_dp:
        Intent i = new Intent(Intent.ACTION_PICK,            
        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        i.putExtra(MediaStore.EXTRA_OUTPUT, setImageUri());  
                startActivityForResult(i, PICK_FROM_GALLERY);
        break;
        case R.id.delete_image_dp:

        break;
       }

       public Uri setImageUri() {
          
         File file = new File(Environment.getExternalStorageDirectory()        
                     +"/android/data/spaj_foto/spaj_foto("+counter+").png");
         Uri imgUri = Uri.fromFile(file);
         this.imgPath = file.getAbsolutePath();
         return imgUri;
       }
       public String getImagePath() {
        return imgPath;
       }

       @Override
       public void onActivityResult(int requestCode, int resultCode, Intent data) {  
         if (resultCode != Activity.RESULT_CANCELED) {
                    if (requestCode == TAKE_PHOTO_CODE) {
                    selectedImagePath = getImagePath();
                    foto_dp.setImageBitmap(decodeFile(selectedImagePath));

                    if (requestCode == PICK_FROM_GALLERY) {
                        selectedImagePath = getImagePath();
                        foto_dp.setImageBitmap(decodeFile(selectedImagePath));
                    }
                } else {
                    super.onActivityResult(requestCode, resultCode, data);
                }
            }
       }
       public Bitmap decodeFile(String path) {
            try {
                // Decode image size
                BitmapFactory.Options o = new BitmapFactory.Options();
                o.inJustDecodeBounds = true;
                BitmapFactory.decodeFile(path, o);
                // The new size we want to scale to
                final int REQUIRED_SIZE = 70;

                // Find the correct scale value. It should be the power of 2.
                int scale = 1;
                while (o.outWidth / scale / 2 >= REQUIRED_SIZE && o.outHeight / scale / 2 >=   
                       REQUIRED_SIZE)
                    scale *= 2;

                // Decode with inSampleSize
                BitmapFactory.Options o2 = new BitmapFactory.Options();
                o2.inSampleSize = scale;
                return BitmapFactory.decodeFile(path, o2);
            } catch (Throwable e) {
                e.printStackTrace();
            }
            return null;

        }   

If we want to ADD the album directly, we can also use this method :

AlbumEntry myAlbum = new AlbumEntry();

myAlbum.setTitle(new PlainTextConstruct("Trip to France"));
myAlbum.setDescription(new PlainTextConstruct("My recent trip to France was delightful!"));

AlbumEntry insertedEntry = myService.insert(postUrl, myAlbum);

If we want to remove the album data, we can use the method :

myAlbum.delete();
