问题 I'm attempting to put an ImageView in a CollapsingToolbarLayout in which it takes up the full screen on load and as you scroll the content, the 16x9 resolution image width resizes until the image takes up the full width of the screen. At that point, I'd like the image to parallax with a app:layout_collapseParallaxMultiplier of 0.5 Using this XML Layout: <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res
