由 六月ゝ 毕业季﹏ 提交于 2019-11-26 21:15:54
问题 I'm trying to replace Picasso in my android app with Fresco. However I am unsure of how to simply load a bitmap using Fresco. With Picasso I would just do the following. Bitmap poster = Picasso.with(getActivity()) .load(url) .resize(Utils.convertDpToPixel(WIDTH,HEIGHT)) .centerCrop() .get(); I have been unable to figure out how to create a Bitmap with this Fresco. Any ideas? 回答1: As Fresco said: If your request to the pipeline is for a decoded image - an Android Bitmap, you can take advantage

OkHTTP and Picasso don't run together

由 假装没事ソ 提交于 2019-11-26 20:35:38
问题 I use Picasso library in my project to load images ande cache them. It works good without any problem. However, when I try to use OkHttp library to perform data communication with my server (JSON communication), Picasso throws exceptions. I use the following jars : okhttp-2.0.0-RC2, okio-1.0.0, picasso-2.2.0. When I run my project after I add these jars, It crashes with the following : 06-12 11:13:15.824: E/dalvikvm(12105): Could not find class 'com.squareup.okhttp.HttpResponseCache',

I'm using picasso library to load images for my app. But I don't how to implement my own disk (sdcard) caching with picasso library. Jake Wharton Picasso uses the HTTP client for disk caching and if one is already configured it will use that instead of installing its own. For the built-in UrlConnection the docs for installing a cache are here: https://developer.android.com/reference/android/net/http/HttpResponseCache.html If you are using OkHttp then you just call setCache: http://square.github.io/okhttp/2.x/okhttp/com/squareup/okhttp/OkHttpClient.html#setCache-com.squareup.okhttp.Cache- @Dax,

Android + Picasso: changing URL cache expiration

由 给你一囗甜甜゛ 提交于 2019-11-26 18:21:05
问题 I am using Picasso to download and display images in views all accros my application. Those images are changing very rarely (they are considered valid for a few months). Is there a simple way to ask Picasso (or the underlying okHttp) to keep those images on disc for this much time? 回答1: Disk caching happens "below" Picasso inside the HTTP client. In fact, this process is completely transparent. We never explicitly ask for a cached-version or an internet-version, the HTTP client will make the

Using Picasso with custom disk cache

由 佐手、 提交于 2019-11-26 16:17:27
In Volley library, the NetworkImageView class requires an ImageLoader that handles all the image requests by searching for them inside an ImageCache implementation, the user is free to choose how the cache should work, the location and the name of the images. I'm switching from Volley to Retrofit , and for the images I decided to try Picasso . With the former library, I had a String parameter in each of my items containing the image URL, then I used myNetworkImageView.setImageUrl(item.getURL()) and it was able to determine if image was cached on disk. If the image existed in cache folder, the

Picasso Load image from filesystem

由 房东的猫 提交于 2019-11-26 16:13:12
Can I use Picasso library to load images from the filesystem? I'm using startActivityForResult to let the user pick a photo from his gallery, and then want to show the selected image. I already have working code to get the image filesystem Uri , but can't get the Picasso.load() method to work. Of course you can. Its actually pretty straight forward: File f = new File("path-to-file/file.png") or File f = new File(uri) Picasso.with(getActivity()).load(f).into(imageView); also Picasso.with(getActivity()).load(uri).into(imageView); works egfconnor Yes you can. Try: Picasso.with(context).load(new
