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: just use Glide. It’s much more powerful and configurable. Years ago I had to fork and … Read more
You can use a Callback to get onSuccess and onError events. Just add a new Callback to your request like so: Picasso.with(getContext()) .load(url) .into(imageView, new com.squareup.picasso.Callback() { @Override public void onSuccess() { } @Override public void onError() { } }); Then you can perform any alterations and modifications in the onSuccess callback.
Research a bit before as there are answers available. Anyhow, follow This Link and read it carefully to know how to use it. try this: import com.squareup.picasso.Transformation; public class CircleTransform implements Transformation { @Override public Bitmap transform(Bitmap source) { int size = Math.min(source.getWidth(), source.getHeight()); int x = (source.getWidth() – size) / 2; int y = … Read more
How to have a loading progress animation image using Picasso placeholder: I solved this easily using a animated-rotate xml object. Steps: progress_image.png /res/drawable/progress_animation.xml <?xml version=”1.0″ encoding=”utf-8″?> <layer-list xmlns:android=”http://schemas.android.com/apk/res/android”> <item android:gravity=”center”> <animated-rotate xmlns:android=”http://schemas.android.com/apk/res/android” android:drawable=”@drawable/progress_image” android:pivotX=”50%” android:pivotY=”50%” /> </item> </layer-list> Picasso loading: Picasso.with( context ) .load( your_path ) .error( R.drawable.ic_error ) .placeholder( R.drawable.progress_animation ) .into( image_view );
This is what I did. Works well. First add the OkHttp to the gradle build file of the app module: compile ‘com.squareup.picasso:picasso:2.5.2’ compile ‘com.squareup.okhttp3:okhttp:3.10.0’ compile ‘com.jakewharton.picasso:picasso2-okhttp3-downloader:1.1.0’ Then make a class extending Application import android.app.Application; import com.jakewharton.picasso.OkHttp3Downloader; import com.squareup.picasso.Picasso; public class Global extends Application { @Override public void onCreate() { super.onCreate(); Picasso.Builder builder = new Picasso.Builder(this); … Read more
As noted by the other respondents (@lukas and @mradzinski), Picasso only keeps a weak reference to the Target object. While you can store a strong reference Target in one of your classes, this can still be problematic if the Target references a View in any manner, since you’ll effectively also be keeping a strong reference … Read more
You are looking for: .fit().centerCrop() What these mean: fit – wait until the ImageView has been measured and resize the image to exactly match its size. centerCrop – scale the image honoring the aspect ratio until it fills the size. Crop either the top and bottom or left and right so it matches the size … Read more
You have a few options here: Pass Context as an argument to FeedAdapter and keep it as class field Use dependency injection to inject Context when you need it. I strongly suggest reading about it. There is a great tool for that — Dagger by Square Get it from any View object. In your case … Read more
I am one of the engineers on the Fresco project. So obviously I’m biased. But you don’t have to take my word for it. We’ve released a sample app that allows you to compare the performance of five libraries – Fresco, Picasso, UIL, Glide, and Volley Image Loader – side by side. You can get … Read more
