Resizing screen

I want to make a menu which will show on the right side of the desktop.
the screen size will decrease from the area for this menu (green part) and the remaining part of the screen (Purple area) will remain the same behavior as the full screen with new width. for example, if I add maximized windows on the screen(Purple area) it will cover the purple area completely only not the green area,

Designing for full screen

Summary: I'm having a big problem with layout design in my project... I want to set it up in fullscreen mode, but I can only set it in a specify resolution, because of that, when I click to maximize my program, it goes like image #2... I tried to anchor buttons in "Top,Left,Bottom,Right" but the mess is bigger (image #3).

Use scrollToEnd({animated: true}) to go the bottom of scrollView in react-native.
From doc.s of facebook https://facebook.github.io/react-native/docs/scrollview#scrolltoend
scrollToEnd()
If this is a vertical ScrollView scrolls to the bottom. If this is a horizontal ScrollView scrolls to the right.
Use scrollToEnd({animated: true}) for smooth animated scrolling, scrollToEnd({animated: false}) for immediate scrolling. If no options are passed, animated defaults to true.

Android wallpaper also sliding left and right when we swipe the home screen

I want to develop a new home screen application for android. I saw the default home screen in my android 2.3.3 device, when ever I swipe the home screen left and right, the background wallpaper also sliding left and right. What is that view? How to get the same effect in an app?
Is it ViewPager? I checked the ViewPager class, but I didn't found any common background image for all views in that.
You probably want to use a canvas with a draw-able, then detect the users swiping and animate it in the background. It is likely that the default android backgrounds are doing the same. You wont be drawing the unseen portions of the view.

I suggest doing their lunar lander tutorial to learn how to use the canvas first.
You will make a canvas the background to your app and then lay your other ui elements on top of it unless you make the ui based inside the canvas.
