What should I do to obtain a normal URL that I will be able to use do downloand the image into my Android app? Thank you in advance! Here I post some code I use: Upload to Firebase DataBase and Storage: mStorageRef = FirebaseStorage.getInstance().getReference(); mDataBaseRef = FirebaseDatabase

如何在Android中通过URL加载ImageView? [关闭]

如何在 ImageView 使用URL引用的 ImageView ? #1楼 一种简单而干净的方法是使用开源库 Prime 。 #2楼 如果您是通过单击按钮加载图像的,则上面接受的答案很好,但是,如果您在新活动中进行图像加载,则会冻结UI一两秒钟。 环顾四周,我发现一个简单的asynctask消除了这个问题。 要使用asynctask,请在活动结束时添加此类: private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> { ImageView bmImage; public DownloadImageTask(ImageView bmImage) { this.bmImage = bmImage; } protected Bitmap doInBackground(String... urls) { String urldisplay = urls[0]; Bitmap mIcon11 = null; try { InputStream in = new java.net.URL(urldisplay).openStream(); mIcon11 = BitmapFactory.decodeStream(in); } catch (Exception e) { Log.e("Error", e

Android图片加载框架之Picasso

相信做Android开发的对Square公司一定不会陌生,大名鼎鼎的网络请求框架Retrofit就来源于它,今天学习的是该公司出品的图片加载框架Picasso。 项目地址 https://github.com/square/picasso 使用说明 http://square.github.io/picasso/ Gradle: compile 'com.squareup.picasso:picasso:2.5.2' ProGard混淆配置: -dontwarn com.squareup.okhttp.** 简介 图片为Android应用增加必要的背景和视觉,Picasso使得你可以在应用中轻而易举地实现图片加载,只需一行代码! Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView); 许多在Android上图片加载常见的的陷阱都被Picasso自动的处理了: 在 adaper 中处理 ImageView 循环和取消下载 对复杂图像进行转换,使其占用最小的内存 自动的内存和磁盘缓存 特性 在Adapter中下载 自动检测Adapter重用并取消之前的下载 @Override public void getView(int position, View convertView,

为何在Fresco,Glide这么强大的背景下,我又想起了当初的Picasso,又为何写这篇文章?是因为最近项目采用了square公司的RxAndroid,Retrfit和OKhttp, 不得不联想到这个公司曾经还有款图片加载Picasso,所以采用了square公司的全家桶来进行项目开发,为了减少开发成本和也防止Apk增大,毕竟一个公司的框架之前兼容性不用担心,那么请让我们回顾一下Picass之路 首先先让我们看看主流图片加载库 Picasso,Square公司的开源项目 ,和Square的网络库一起能发挥最大作用。占用内存小,自身不带缓存,需依赖OKhttps实现缓存,不支持gif图片 Fresco,FB的明星项目,也是2015最火的项目之一,匿名共享缓存等机制保证低端机表现极佳,但是源代码基于C/C++,阅读困难度提升。效率高,sdk库占用包体积比较大 Glide,Google员工私人项目,但是Google很多项目在用,占用内存小,减低oom更靠谱,相对Picasso在Gif方面有优势,并自带缓存功能! 我做了一个实验对比 用一个普通listview加载50张图片,并快速滑动列表,下面分别是glide和picasso消耗内存图 分析后得出 一个占用内存大 一个占用cpu资源大, 这种区别是由于picasso只缓存一张大图,每次加载根据imagview的大小裁剪

Picasso doesn't tolerate empty String URL?

问题 I have a viewHolder that loads up an image using Picasso. The DB will return a path of URL as String. So I have my code as below (Using Kotlin) Picasso.with(context).load(url).error(placeholder).transform(transformation) .placeholder(placeholder).into(this) It loads fine. However, sometimes the URL is empty. I'm expecting it to load the placeholder instead. But it crash out as below java.lang.IllegalArgumentException: Path must not be empty. at com.squareup.picasso.Picasso.load(Picasso.java

Get redirected URL from Picasso

我怕爱的太早我们不能终老 提交于 2020-01-24 16:27:10
问题 I'm fetching my images using the following code: Picasso.with(mContext) .load(myImage.getUrl()) .fetch(); myImage.getUrl() returns a URL from my server, which will redirect to the actual image hosted on another server. Is there a way to catch the URL my server returns to Picasso? I know I can use a Callback in .fetch() , but that's all I know. I'm using OkHttp as well. 回答1: OkHttp allows you not to follow redirects automatically : OkHttpClient client = new OkHttpClient(); client

How to make Picasso load images faster?

问题 I use Picasso (image downloading library for Android). Picasso website I charge my image like this: Picasso.get().load("http://i.imgur.com/myImage.png").into(imageView); But, if myImage.png is too big, the download become slow.

Note that I cannot touch the file myImage.png --------------------- EDIT Any
