Just displaying an image using Picasso is as simple as:. For more control you can implement the Target interface and use it to load your image into - this will provide callbacks similar to the Volley example.
Check the demo project for examples. Picasso also lets you apply transformations to the downloaded image and there are even other libraries around that extend those API. Universal Image Loader is an another very popular library serving the purpose of image management. It uses its own ImageLoader that once initialized has a global instance which can be used to download images in a single line of code:.
The opts argument in this example is a DisplayImageOptions object. Refer to the demo project to learn more. Note : the author has mentioned that he is no longer maintaining the project as of Nov 27th, But since there are many contributors, we can hope that the Universal Image Loader will live on. Facebook's Fresco is the newest and IMO the most advanced library that takes image management to a new level: from keeping Bitmaps off the java heap prior to Lollipop to supporting animated formats and progressive JPEG streaming.
To learn more about ideas and techniques behind Fresco, refer to this post. The basic usage is quite simple. Note that you'll need to call Fresco. Initializing Fresco more than once may lead to unpredictable behavior and OOM errors. Fresco uses Drawee s to display images, you can think of them as of ImageView s:. As you can see, a lot of stuff including transformation options gets already defined in XML, so all you need to do to display an image is a one-liner:.
Fresco provides an extended customization API, which, under circumstances, can be quite complex and requires the user to read the docs carefully yes, sometimes you need to RTFM. Note that the following text reflects my personal opinion and should not be taken as a postulate.
In case you missed that, the Github link for the demo project. I have just came from solving this problem on and I would like to share the complete code that can download, save to the sdcard and hide the filename and retrieve the images and finally it checks if the image is already there. The url comes from the database so the filename can be uniquely easily using id. Why do you really need your own code to download it? How about just passing your URI to Download manager? I have a simple solution which is working perfectly.
The code is not mine, I found it on this link. Here are the steps to follow:. It needs a context, better to use the pass in the application context by getApplicationContext.
This method can be dumped into your Activity class or other util classes. This private class need to be placed in your Activity class as a subclass. After the image is downloaded, in the onPostExecute method, it calls the saveImage method defined above to save the image. The AsyncTask for downloading the image is defined, but we need to execute it in order to run that AsyncTask. To do so, write this line in your onCreate method in your Activity class, or in an onClick method of a button or other places you see fit.
IMO this solves the issue! If you want further steps such as load the image you can follow these extra steps:. After the image is downloaded, we need a way to load the image bitmap from the internal storage, so we can use it. This method takes two paramethers, a context and an image file name, without the full path, the context. Now we have everything we needed for setting the image of an ImageView or any other Views that you like to use the image on. Droidman post is pretty comprehensive.
Volley works good with small data of few kbytes. When I tried to use the 'BasicImageDownloader. I used Volley in another test app and that kept crashing because of leaks so I am worried about using Volley for the image downloader images can be few kB. I used Picasso and it worked well, there is small change probably an update on Picasso from what is posted above.
Below code worked for me:. The inner gallery is not fetching data above th rown from sharepoint am getting blank displayed, But the Upper gallery its fetching correctly, what can be done? My solution includes an Image media and Timer input. It can include more columns, depending on the needs.
