Solution

  • Your requirement is very delicate. As TouchImageView is a custom widget, it may not have been dealt with NestedScrollView. Use PhotoViewAttacher to your ImageView and see if this works.

    Add this to dependency in the app gradle: 

     dependencies {
  compile 'com.commit451:PhotoView:1.2.4'
}

    In Java Class:

    PhotoViewAttacher pAttacher;
pAttacher = new PhotoViewAttacher(Your_Image_View);
pAttacher.update();

    And then Attach your ImageView inside the NestedScrollView: 

    <android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

           //Add ImageView Here

     </android.support.v4.widget.NestedScrollView>
