Hey. As the image loader chose Fresco. It is necessary to cache pictures to disk and, when I'm offline, get them from the cache. Tell me how to implement it.
Dock links do not send please. Doku read, did not understand. Therefore, I ask a question here. And do not offer other options such as Glide and Picasso
In general, I found how it can be configured in Fresco
val diskCacheConfig = DiskCacheConfig.newBuilder(this).setBaseDirectoryPath(this.cacheDir) .setBaseDirectoryName("image") .setMaxCacheSize((100 * ByteConstants.MB).toLong()) .setMaxCacheSizeOnLowDiskSpace((10 * ByteConstants.MB).toLong()) .setMaxCacheSizeOnVeryLowDiskSpace((5 * ByteConstants.MB).toLong()) .setVersion(1) .build() val imagePipelineConfig = ImagePipelineConfig.newBuilder(this) .setMainDiskCacheConfig(diskCacheConfig) .build() Fresco.initialize(this, imagePipelineConfig) It is enough to register all this in Application and use for SimpleDraweeView
You can use Picasso caching in it automatically.
Round Transformation:
/** * @author zTrap * @date 05.09.2016. */ public class CircleTransform implements Transformation { @Override public Bitmap transform(Bitmap source) { int size = Math.min(source.getWidth(), source.getHeight()); int x = (source.getWidth() - size) / 2; int y = (source.getHeight() - size) / 2; Bitmap squaredBitmap = Bitmap.createBitmap(source, x, y, size, size); if (squaredBitmap != source) { source.recycle(); } Bitmap bitmap = Bitmap.createBitmap(size, size, source.getConfig()); Canvas canvas = new Canvas(bitmap); Paint paint = new Paint(); BitmapShader shader = new BitmapShader(squaredBitmap, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP); paint.setShader(shader); paint.setAntiAlias(true); float r = size / 2; canvas.drawCircle(r, r, r, paint); squaredBitmap.recycle(); return bitmap; } @Override public String key() { return "circle"; } } Using:
Picasso.with(this).load(profile.photo) .placeholder(R.drawable.no_avatar) .transform(new CircleTransform()) .resize(200, 200) .centerCrop() .into(avatar);
