Is there a way to absolutely position an UI element on Android so that it is located outside an Activity? For example: can you create a fullscreen ImageView simply by moving/resizing an ImageView inside an existing regular Activity instead of creating a new fullscreen activity?
EDIT: Re-reading my question I see I wasn't very clear about what I'm trying to accomplish. I'd like to temporarily extend an element to cover the notification bar at the top of the screen. I need to create a semitranslucent fullscreen overlay but since translucent activities cannot cover the notification bar I'm trying to find out if it's possible for an element to break out of activity's bounds and resize itself to fill the whole screen, top to bottom.
That depends on what specifically you're trying to do. You can easily draw graphics offscreen and then animate their movement into the screen using a Canvas, but this is more for graphics than for user-interface elements. For moving buttons or such, you can have a look at another question here "How to position View off-screen". I gave a brief intro on how to use canvases, but the questioner found another way to do it using a customised linear layout and view animations.
Lastly, if you're trying to zoom and scroll an image around that's larger than the ImageView, there are some sources you can look at for inspiration. I realies this isn't strictly your question, but I'm including it since it might be linked to what you're thinking about. You can find a tutorial on Anddev.org and an open source app on Google Code.

I want to customize the FullWidthDetailsOverviewRowPresenter in the Leanback DetailFragment.
Three things I want to accomplish are:
Getting the Actions from top to below of the overview.
Reducing the height of the overview so that it the related movies can be seen without scrolling down.
The background image and the space it occupies at the top of the overview should be gone. The screen should start like the one above.
The end result should be like this:
I already know how to modify inside the overview. How should I modify outside of it?
Because you are moving around the key views of this screen, it sounds like you might have to ditch the current implementation altogether and create your own custom view from scratch. By moving the buttons to the bottom and the detail image (seems like you're moving it to the right side of the description text), you're making it less and less justifiable to even subclass DetailFragment. The developers of Leanback were probably intentional about limiting customizing the interfaces too much as they want a consistent experience for different apps.
I would create a new layout file and load it up on your subclass of DetailsFragment (or DetailsPresenter), depending on your architecture.

In 1st Row create a Rowpresenter that fits your design with buttons
In other row/s add ListRowPreesenter
I'm trying to make my app be able to draw with your finger like Snapchat on part of the screen but not the whole thing? Every example I have seen of drawing is just an app that turns your whole screen into the canvas and does nothing else but I'm having a hard time implementing it as just part of my app. So as well as how to just choose a section of the screen as the canvas is it possible to make another activity just like the examples that extends view that I include or can I put everything in MainActivity.java?
Yes, there is. You can create a fragment, or as many as you want, and them place the fragment(s) wherever you want in the activity by using some of the available layouts.
For example, you can use a relative layout. You can add a frame layout to the relative layout and align it in the activity where you want, set its size, and then add the fragment to it. You can check this link to learn about fragments and their usage if you don't know them.
I have an activity that must be used horizontally.
this activity shows a map and when i click on it a toolbar supposed to pop from the right side of the screen (which is actually the bottom if we are looking vertically).

i thought of implementing this toolbar as a container of fragments because each button triggers different stuff to appear on the toolbar.
First of all, is it the best way to implement such a toolbar? or are there more android oriented ways?
Second, i would like that when i touch the "transparent" space under the X button it would send this signal to the map but when i touch the "black transparent" it will not.
From what I've read the only way is when clicking check coordinates and see of they fall inside my area but it sounds too hardcoded and ugly solution.
Is there a better one? maybe there is a way to make the holding layout fit the image and not be rectangular?
For a more android oriented way you can use the Navigation drawer.
I don't know if it fit exactly with what you want but Navigation drawers are a good way to create right or left menu/toolbar.
You can find the documentation here:
https://developer.android.com/design/patterns/navigation-drawer.html

I need an android component that will hold two views (one on top, and the second one ont he bottom). There will also be a slider between views.
It will look something like this:
View 1 is bigger than shown and user can expand it by moving down the separator (dark grey rectangle on the picture above). While expanding, View 2 will go down and will not be covered by View 1 (not like in android's notification panel).
Is there some kind of ready to use library for this? If not - could you point me in the right direction how to achieve this?
I haven't done this but I think you can scale the view by draggin. see this to know about this method.
Your question is from years ago, but I've had the same problem recently. Now that we can do nice things with the Design library with scrolling and resizing, this question has become even more important.
So I'd like to point out a library called SubAppBarPanel, that allows you to expand an area from below the app bar. When it's expanded, it pushes down the main content (see GIF).
Is it possible to create a layout based on (background) images? For example, there is well know app called Appie that uses this picture as a homescreen:
I might be able to recreate the layout with a TableLayout, but this will be difficult to get it perfectly aligned with the buttons in the image. The default layout options make it very difficult, or maybe impossible, to allow for selection of the buttons on the image (especially when the buttons are in an arc-path).
Can anyone tell me how this is done?
I had some issues positioning a badge on the corner of a view. You can check my solved question:
Positioning a badge bubble on the left upper side of a button
About how it can be done. I would do it with a RelativeLayout and TableLayout as you mentioned, but to be completely sure, you can use apktool to see how the xml are done but it might be ilegal to do it.
