Add sticky title to parallax scroll - android

Question

I want to have parallax scrolling in my application, as well as a spotify application with a sticky header. This means that the title will be docked at the top of the screen. I found many ScrollView libraries that perform these functions separately, I can not find any libraries with both.

I use the ParallaxScroll library to scroll through parallex and StickyScrollViewItems to stick to the top of the screen.

Any help is greatly appreciated.

If you do not want to use the library, you can just get the logic of creating a sticky header from here: -

@Override public void onScrollChanged(int scrollY, boolean firstScroll, boolean dragging) { if (dragging) { int toolbarHeight = mToolbarView.getHeight(); if (firstScroll) { float currentHeaderTranslationY = ViewHelper.getTranslationY(mHeaderView); if (-toolbarHeight < currentHeaderTranslationY) { mBaseTranslationY = scrollY; } } float headerTranslationY = ScrollUtils.getFloat(-(scrollY - mBaseTranslationY), -toolbarHeight, 0); ViewPropertyAnimator.animate(mHeaderView).cancel(); ViewHelper.setTranslationY(mHeaderView, headerTranslationY); } } 

/// is the key method to make the look sticky.

 setTranslationY(float translationY) 

Sets the vertical position of this view relative to its upper position.

I answer so late, but I hope my answer helps someone. I also had such a task. I was looking for answers and sticky header examples, but for recyclerView. I found the best and easiest solution in the article “Sticky heading for RecyclerView” by Saber Soluki.

Based on this example, I made my contact module for my application, it is very simple.

To scroll through parallax, see the AppBarLayout scroll behavior with layout_scrollFlags in this article. You can combine both of these examples.
