Why use Android Picasso library to download images?

由 邮差的信 提交于 2019-11-26 16:05:44
Why should I download the images via the Picasso library instead of just using this code: private Bitmap DownloadImage(String URL) { Bitmap bitmap = null; InputStream in = null; try { in = OpenHttpGETConnection(URL); bitmap = BitmapFactory.decodeStream(in); in.close(); } catch (Exception e) { Log.d("DownloadImage", e.getLocalizedMessage()); } return bitmap; } Another question: Does Picasso download the image in the UI or by background thread? Just for the record for anyone new to Android or perhaps moving to Android from iOS .......... Until something drastically changes, you absolutely have

Recyclerview painfully slow to load cached images form Picasso

由 别来无恙 提交于 2019-11-26 15:22:32
问题 I have implemented a RecyclerView that contains mainly images which is loading in through Picasso. My problem is that as soon as I scroll down or up the view, the placeholder image appears for approx. a second before it is replaced by the actual image. It scrolls very smoothly, but is practically unusable. This happens every time something scrolls off the screen. Picasso is clearly caching the images to the disk, as they load faster than the initial load time, but they are definitely

Local image caching solution for Android: Square Picasso, Universal Image Loader, Glide, Fresco?

由 与世无争的帅哥 提交于 2019-11-26 12:40:47
I am looking for an asynchronous image loading and caching library in Android. I was going to use Picasso, but I found Universal Image Loader is more popular on GitHub. Does anyone know about these two libraries? A summary of pros and cons would be great. (All my images are on disk locally, so I don't need networking, therefore I don't think Volley is a fit) Update Sep 2018: After several years, I needed the almost same thing for a local image caching solution. This time around, UIL has not been in active development. I compared the popular libraries, and the conclusion is pretty no-brainer:

Picasso loading of image spawned inside AsyncTask

由 醉酒当歌 提交于 2019-11-26 12:31:42
问题 So I am trying to use the Picasso Library for image downloading and caching. In order to get the contactUri to pass to Picasso I need to make a query to the Contacts Content Provider . Since I don\'t want to block the main UI thread to get the contactId, I have put this in an AsyncTask . And once I get that contactId, I make the call to Picasso in the onPostExecute() method of the AsyncTask . However, I am noticing a flickering that shows up when I scroll through my ListView quickly. It seems

Using Picasso library with ListView

由 不想你离开。 提交于 2019-11-26 11:19:49
问题 What I\'m trying to do is adapt my custom ListView adapter to use images fetched from the web by the Picasso library. I believe I have my adapter changed in order to accept an image from Picasso, but I am unsure how to change my implementation to accept it using a ListView. I believe I have to access holder.imageIcon, but I am not sure how to get it up and running. My code is as follows. History.java public class History { public String score; public String gametype; public Picasso icon;

Picasso load drawable resources from their URI

问题 I have to show a drawable from res into an ImageView . In this app, I\'m using Picasso for some reasons. In this case, I need to load the drawable using its URI and not its id. To do that, here is my code: uri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + \"://\"+context.getPackageName()+\"/drawable/\" + drawableName); where drawableName used here are file names rather than their resource ids. Then Picasso.with(context).load(uri).into(imageView); I know for sure that drawable name is

Load images from disk cache with Picasso if offline

由 安稳与你 提交于 2019-11-26 11:03:47
问题 I have some images that I download from different web sites when the app starts, by doing this: Picasso.with(context).load(image_url).fetch(); Now, suppose the user closes the app and turns offline. When the app starts again, Picasso display the images in this way: Picasso.with(ctx).load(image_url).placeholder(R.drawable.ph).into(imageView); The problem is that some images are loaded from the disk cache (yellow triangle in debug mode), and for the others Picasso shows the placeholder. Why? I\

android: create circular image with picasso

由 丶灬走出姿态 提交于 2019-11-26 10:18:37
问题 The question had been asked and there had been a promise made for the very version of Picasso that I am using: How do I send a circular bitmap to an ImageView using Picasso? I am new to Picasso and only thing I have used is Picasso.with(context).load(url).resize(w, h).into(imageview); I have already found https://gist.github.com/julianshen/5829333 but I am not sure how to combine it with the line above in a non-awkward way. 回答1: Research a bit before as there are answers available. Anyhow,
