I used Glide library to load image into imageView and I don't know how to make image pinch to zoomable

Question

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    //Variables
    ImageView imageView;
    imageView = (ImageView) findViewById(R.id.imageView);

    //Loading into ImageView
    Glide.with(this)
            .load("http://vrijeme.hr/bradar.gif")
            .into(imageView);
}

I tried using Picasso too and then connecting it with PhotoView library but it didn't do anything, when I tried pinch to zoom it didn't zoom at all, here is part of that code:

ImageView imageView;
PhotoViewAttacher photoView;

imageView = (ImageView) findViewById(R.id.imageView);
photoView = new PhotoViewAttacher(imageView);
Picasso.with(this)
       .load("link")
       .resize(1080,80)
       .into(imageView);

Answer 1

This library here called PhotoView is quite popular.
https://github.com/chrisbanes/PhotoView

With 13,500+ stars, 30+ contributors backing it, so many people using it and how easy it is to integrate into a project, it almost feels like a standard.

It's also compatible with Glide ^.^

Installation (Official documentation by chrisbanes)

Add this in your root build.gradle file (not your module build.gradle file):

allprojects {
    repositories {
        maven { url "https://jitpack.io" }
    }
}

Then, add the library to your module build.gradle

dependencies {
    implementation 'com.github.chrisbanes:PhotoView:latest.release.here'
}

At that time of writing, latest.release.here is 2.1.4.

Usage (Official documentation by chrisbanes)

There is a sample provided which shows how to use the library in a more advanced way, but for completeness, here is all that is required to get PhotoView working:

<com.github.chrisbanes.photoview.PhotoView
    android:id="@+id/photo_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

PhotoView photoView = (PhotoView) findViewById(R.id.photo_view);
photoView.setImageResource(R.drawable.image);

That's it!

Usage with Glide

Nothing changes!!

PhotoView photoView = (PhotoView) findViewById(R.id.photo_view);
Glide.with(this).load(imageUrl).into(photoView);
