Android使用Glide防止内存溢出

1、加载图片方式。

            GlideApp.with(mContext).asDrawable()
                    .load(model.getPicUrl() + "?x-oss-process=style/optmize-min")
                    .diskCacheStrategy(DiskCacheStrategy.RESOURCE)
                    .placeholder(R.drawable.cache)
                    .transition(DrawableTransitionOptions.withCrossFade()) //淡出淡入动画
                    .into(new ImageViewTarget<Drawable>(holder.imageView) {
                            @Override
                            protected void setResource(@Nullable Drawable resource) { if(resource!=null) {
                                holder.imageView.setImageDrawable(resource);
                            }
                        }
                    });

2、在列表中，如果视图不可见则销毁。

    @Override
    public void onViewRecycled(@NonNull BaseRecyclerViewHolder holder) {
        super.onViewRecycled(holder);
        ClassGoodsAdapter.ClassesGoodsHolder newHolder = null;
        if(holder instanceof ClassGoodsAdapter.ClassesGoodsHolder) {
            newHolder = (ClassGoodsAdapter.ClassesGoodsHolder)holder;
        }
        ImageView imageView = newHolder.imageView;
        if (imageView!=null){
            GlideApp.with(mContext).clear(imageView); //销毁
        }
    }

3、使用弱应用的方式。

   SoftReference<Bitmap> bitmapSoftReference = new SoftReference<>(QRCodeUtil.createQRCodeBitmap(url,
                800, 800,"UTF-8","H", "1", Color.BLACK, Color.WHITE));
