[android] Android ImageView Zoom-in and Zoom-Out

Step 1: First you add dependencies in build.gradle(Module:app) file.

dependencies {

     implementation 'com.jsibbold:zoomage:1.2.0'

    }

Step 2: Next create a class

ImageFullScreenFragment.java

public class ImageFullScreenFragment{

   private ZoomageView ImageZoomageView;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = null;

      try {
         view = inflater.inflate(R.layout.fragment_image_full_screen, container, false);
            ImageZoomageView = view.findViewById(R.id.imageViewImageFullScreen);
            ImageZoomageView.setImageResource(R.drawable.image);

         } catch (Exception e) {
             e.printStackTrace();
         }
    return view;

}

Step 3 : Next create a layout xml file

fragment_image_full_screen.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="8dp"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <com.jsibbold.zoomage.ZoomageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:zoomage_restrictBounds="false"
        app:zoomage_animateOnReset="true"
        app:zoomage_autoResetMode="UNDER"
        app:zoomage_autoCenter="true"
        app:zoomage_zoomable="true"
        app:zoomage_translatable="true"
        app:zoomage_minScale="0.6"
        app:zoomage_maxScale="8"
        android:id="@+id/imageViewImageFullScreen"
        />

</RelativeLayout>
