Recycler Networkimageview Scrolling Back And Forward, Out Of Memory And Resizing Issues

I am working to add an image from the gallery horizontally using recycler view as follows. I could able to add images next to each other. The following code works but crashes somet

Solution 1:

You should scale your Bitmap and use caching for reducing loading time. Here on this repository I've put reference code for approaching image loading with scaling and caching.

I report here code to be used for setPic method. This essentially uses an LruCache for improving Bitmap loading while scrolling. This could be a good starting point. Notice also that Bitmap are scaled before putting them in cache.

privatestaticfinalintWIDTH=100;

private LruCache<String, Bitmap> mMemoryCache;

publicvoidsetPic(MyImageView view, String url) {
    Contextcontext= view.getContext();
    if (!TextUtils.isEmpty(url)) {
        if (url.startsWith("http")) {
            view.setImageUrl(url, VolleyHandler.getInstance(context).getImageLoader());
        } else {
            try {
                Uriuri= Uri.parse(url);
                Bitmapbitmap= mMemoryCache.get(url);
                if (bitmap == null) {
                    InputStreamis= context.getContentResolver().openInputStream(uri);
                    bitmap = BitmapFactory.decodeStream(is);
                    Bitmapscaled= ImageUtils.getInstance().scaleBitmap(bitmap);
                    mMemoryCache.put(url, scaled);
                    if (is!=null) {
                        is.close();
                    }
                }
                view.setLocalImageBitmap(bitmap);
            } catch (Exception ex) {
                Log.e("Image", ex.getMessage(), ex);
            }
        }
    } else {
        view.setImageUrl("", VolleyHandler.getInstance(view.getContext()).getImageLoader());
    }
}

public Bitmap scaleBitmap(Bitmap bitmap) {
    intwidth= WIDTH;
    intheight= (WIDTH * bitmap.getHeight()) / bitmap.getWidth();
    return Bitmap.createScaledBitmap(bitmap, width, height, false);
}

I suggest also to refer to Android Developers documentation here (for efficient Bitmap loading) and here (for Bitmap caching with Volley).
