Question

I’ve got a rather peculiar problem. I am trying to pass a number of parameters to a method in a different class, and three out of the four parameters are being passed just fine. The fourth, however, is returning 0 (zero) regardless of what I seem to do.

I am initializing the second class, ImageLoader, without any issues.

Here’s the call in question – I’ve added comments to explain my problem:

imageLoader.DisplayImage(coverFileNames.get(position), Main.this, (ImageView) convertView, position); // coverFileNames.get(position) works great and returns the correct filename based on the position - position on its own, however, doesn't!

And here’s the DisplayImage method:

public int position;

public void DisplayImage(String fileUrl, Activity activity, ImageView imageView, final int pos) {
                position = pos; // this is 0 no matter what I do
                imageViews.put(imageView, fileUrl);
                queuePhoto(fileUrl, activity, imageView);
                imageView.setImageResource(R.drawable.noposterlarge);
            }

Any ideas? Thanks.

EDIT:

Here’s the GetView method:

public View getView(int position, View convertView, ViewGroup parent) {

            if (convertView == null) {
                convertView = (ImageView) new ImageView(Main.this);
            }

            // Create new file for the file path of the movie
            File file = new File(videoUrls.get(position));

            // Create variables for potential custom art check
            boolean potentialImage = false;
            String ImageFile = null;
            String[] potentialImageFiles = new String[]{file.getAbsolutePath().substring(0, file.getAbsolutePath().lastIndexOf(".")) + ".jpg",
                    file.getAbsolutePath().substring(0, file.getAbsolutePath().lastIndexOf(".")) + ".jpeg",
                    file.getAbsolutePath().substring(0, file.getAbsolutePath().lastIndexOf(".")) + ".JPG",
                    file.getAbsolutePath().substring(0, file.getAbsolutePath().lastIndexOf(".")) + ".JPEG"};

            // Check if each file exists and return if one does
            for (String potentialFile : potentialImageFiles) {
                if (!potentialImage) {
                    if (new File(potentialFile).exists()) {
                        potentialImage = true;
                        ImageFile = potentialFile;
                    }
                }
            }

            final BitmapFactory.Options options = new BitmapFactory.Options();
            options.inSampleSize = 2;
            options.inPreferredConfig = Config.RGB_565;

            // Check if there's a custom cover art
            if (potentialImage) {
                Log.d("TEST", "POS: " + position); // this returns the correct value
                imageLoader.DisplayImage(ImageFile, Main.this, (ImageView) convertView, position);
            } else {
                Log.d("TEST", "POS: " + position); // this returns the correct value
                imageLoader.DisplayImage(coverFileNames.get(position), Main.this, (ImageView) convertView, position);
            }

            return convertView;
        }

And again, here’s the DisplayImage method:

public void DisplayImage(String fileUrl, Activity activity, ImageView imageView, final int pos) {
            Log.v("Testing", "position = " + pos); // This returns 0, which is not correct
            imageViews.put(imageView, fileUrl);
            queuePhoto(fileUrl, activity, imageView);
            imageView.setImageResource(R.drawable.noposterlarge);
        }

Answer 1

this is simply impossible

Add to top of DisplayImage

Log.v("DisplayImage", "position = " + position);

---

If it is 0

Change the calling code from

imageLoader.DisplayImage(coverFileNames.get(position), Main.this, (ImageView) convertView, position); 

to

imageLoader.DisplayImage(coverFileNames.get(position), Main.this, (ImageView) convertView, 2); 

Now, will it show 2? It must

---

It means that in your calling code in the line imageLoader.DisplayImage() position has always been 0 for some reason.

coverFileNames.get(position) is always returning the String at position=0

Try removing the final modifier from your DisplayImage function

public void DisplayImage(String fileUrl, Activity activity, ImageView imageView, int pos)
