ParallaxView | tvOS controls and extensions that add parallax effect | iOS library

I am trying to use a ParallaxView to make an image within the GridViewItem parallax as the GridView is scrolled. The intended effect is the same as the newsfeed in the Xbox UWP app on PC; images on the listview items there parallax as you scroll. This is shown visually in the following image:

I am running into a databinding data context issue, however. All of the examples I have seen are to make the background of the entire GridView or ListView parallax. A working example of that is as follows (very similar to the XAML Controls Gallery Sample found here):

Personally I created a PARALLAX effect in my application, but within the effect (PARALLAX) I have a LISTVIEW that shows my content! only when the effect ends, the ListView SCROLL does not work and does not load all the content!

My Code

ParallaxControl.cs

After the April Update of Windows 10 the parallax effect in ParallaxViev Control doesn't work. An example taken from microsoft docs:

I am creating a mini game for Android, available from the playstore, which we call "Moon Buggy". The action is that you control a vehicle on the moon and you should defend yourself from attacking UFO:s.

Now I want to improve the movement of the vehicle. I have code so that it doesn't move outside the screen, and it is possible to accelerate, slow down and jump. But it is not perfect. I was inspired by the classic game Moon Patrol which is measuring time per completed section and my game does that too. So preferably you should be able to accelerate and complete the section faster the more you accelerate perhaps instead of stopping at the end of the screen which my vehicle does now. Also, perhaps it should accelerate faster.

The relevant code is:

ParallaxActivity.java

How can I get started filling up text similar to this screen? Should I use a Handler and delay every character?

The background is that I am coding a mini game for Android similar to the classic Moon Patrol and now I want to create bonus for completing a checkpoint.

You can find my beta in the appstore https://play.google.com/store/apps/details?id=dev.android.buggy It is currently named "Moon Buggy". The code is available on request, right now the repo is closed source.

I put a test checkpoint at checkpoint "C" to show what I try:

I code a mini Android game scenario inspired by Space Invaders and Moon Patrol. It is possible to shoot an alien horizontally (see above).

It is also possible to shoot an alien vertically (see below).

But adding aliens doesn't "scale", it will be very difficult to add for instance 15 aliens moving with respect to all possible collisions. The original space invaders and moon patrol solved this, is it possible to develop a different strategy than the one I am using? The exact movement of aliens is not important, only that it is "fun".

I want a custom view that moves depending on the accelerometers and creating the parallax effect.

Now I have the custom view listening the accelerometers values but, how I can use these values to move the view properly?
