Android之Glide获取图片Path和Glide获取图片Bitmap

               

今天主要研究了Glide获取图片Path、Bitmap用法，相信也困扰了大家很久，我在网上也找了很久，基本没有，后来研究了下，也参考了下api文档，总结了以下几个方式：

1. 获取Bitmap：

1）在图片下载缓存好之后获取

Glide.with(mContext).load(url).asBitmap().into(new SimpleTarget<Bitmap>() {                @Override                public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {                    image.setImageBitmap(resource);                }            }); //方法中设置asBitmap可以设置回调类型

上面是简单方法，下面有全面的方法，可以完美控制：

Glide.with(mContext).load(url).asBitmap().into(new Target<Bitmap>() {                @Override                public void onLoadStarted(Drawable placeholder) {                                    }                @Override                public void onLoadFailed(Exception e, Drawable errorDrawable) {                }                @Override                public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {                     //TODO set bitmap                }                @Override                public void onLoadCleared(Drawable placeholder) {                }                @Override                public void getSize(SizeReadyCallback cb) {                }                @Override                public void setRequest(Request request) {                }                @Override                public Request getRequest() {                    return null;                }                @Override                public void onStart() {                }                @Override                public void onStop() {                }                @Override                public void onDestroy() {                }            });

2）通过url获取

Bitmap myBitmap = Glide.with(applicationContext)    .load(yourUrl)    .asBitmap() //必须    .centerCrop()    .into(500, 500)    .get()

2. 获取图片缓存路径

FutureTarget<File> future = Glide.with(mContext)                    .load("url")                    .downloadOnly(500, 500);            try {                File cacheFile = future.get();                String path = cacheFile.getAbsolutePath();            } catch (InterruptedException e) {                e.printStackTrace();            } catch (ExecutionException e) {                e.printStackTrace();            }

注意：这段代码需要在线程中执行，否则会保存。
