I am creating a project like youtube shorts.
where i have implemented Viewpager2(modal contains only videoview) with RecyclerviewAdapter, everything is ok, but problem is when we swiping both video playing at same time, and some stuck in intial point of scrolling.
So, 1. how to play one video at a time only when screen is fully visible, and second video which coming by scrolling remain pauses or black screen until screen is fully visible?
for smoothness i tried setoffpagelimit method, it plays multiple audio without any scrolling, i think with the solution of first question 2nf question also will solved.

How can I switch the screen and still save the progress of the current game? For example I have an additional screen, when you press tab key, that shows some information about the player (attributes, stats, etc.), but when you switch the screen again to resume your game the show method is called again and you lose everything... The only method I know is that before you hide the screen to save the game in some format and load it in show but I highly doubt that this is the proper way to do it, as there would be a real performance issue when you switch the screens very fast... I need a way to keep the data from the previous screen and not initialize it every time the screen is showed. This would also apply to the skill tree and inventory which also needs to be saved for the entire game session. The filed loading from save game file format should be done only once not every time a screen changes. Any ideas?
So to expand on the question stated, to my best understanding android apps have a set of activities such as the default activity_main.xml and you could even generate a login screen (activity_login.xml). After fiddling around with it I sort of feel comfortable with the way buttons work, yadda yadda, but my problem emerges when I want to create a game activity. I am not concerned about that part, I would just make another activity (activity_gameplay.xml) that I would run the game on. My problem is that I want to render my own custom buttons onto the screen which would be transparent and would be stationary while the actual game environment would be moving. Such as in Minecraft(android version obviously).
So to conclude I need to know how to render custom buttons, and though not included in the above, how to position the buttons accordingly sense the XML way only allows stuff such as upper left-hand corner etc.
I'am using this player as a base for the project:
http://www.androidhive.info/2012/03/android-building-audio-player-tutorial/
I addition to that when I wanted to show different Images (kind of a slideshow) while playing the Audiofile.
Each image has a starttime and duration value.
I've archieved to play this slideshow of images, but with the problem, that I can't stop or pause it.
My Goal is an ImageView where I can controll the shown Image over the seekbar and the Play and Pause function, so that every Image will be shown at the right time while scrolling through the seekbar. (Same like the Audio file gets controlled kind of)
Right know I'm kind of stuck and need some approach to continue my work.
Anybody an idea how to solve this?
I don't know if it's a dumb question because it is one of my first apps.. but if that's the case, please also explain why!
If I create a Tab-Based Activity-Structure, I get nearly what I am asking for but only for Tabs. What I want is generally opening a second or even third activity in one main-activity which contains the main-interface.
Example: I have a Title-Bar and a little icon at the bottom-left corner for some reason during the whole app runtime. Now: How can I control them with the main activity and open at the same time some other activities/views into the existing interface? It should then be shown below the title bar and lying underneath the little icon (the icon is not really important, just fictional). Also it would be nice if I could add some fade in effects to these embedded activities/views. Is that somehow possible?
I currently only know, how to open activities each over another filling the whole screen, except in the case of tabs... maybe I only haven't inspected the tab structure enough.. however, I would be delighted about each answer!

What you are looking for, are Fragments.
Fragments can be used to fill a part of the screen, while doing something else entirely in a different one.
In your example you can create a main activity that contains two Fragments. One Fragment controls the title bar, the other one controls the main content area.
By replacing the current Fragment in your content area with a different one on the press of a button, you can achieve the behavior you are looking for. At least, that's how I did it in an app of mine containing a main content area and a music player. The music player stays in place while the main content changes.
Sadly I can't provide any example code right now, but here is a tutorialthat should help you get started:
Android User Interface Design: Working With Fragments
I'm trying to create a "scrollable" layout in Android. Even using developers.android.com, though, I feel a little bit lost at the moment. I'm somewhat new to Java, but not so much that I feel I should be having these issues--being new to Android is the bigger problem right now.
The layout I'm trying to create should scroll in a sort of a "grid". I THINK what I'm looking for is the Gallery view, but I'm really lost as to how to implement it at the moment. I want it to "snap" to center the frame, like in the actual Gallery application.
Essentially, if I had a photo gallery of 9 pictures, the idea is to scroll between them up/down AND side to side, in a 3x3 manner. Doesn't need to dynamically adjust, or anything like that, I just want a grid I can scroll through.
I'm also not asking for anyone to give me explicit code for it--I'm trying to learn, more than anything. But pointing me in the right direction for helpful layout programming resources would be greatly appreciated, and confirming if it's a Gallery view I'm looking for would also be really helpful.
EDIT: To clarify, the goal is to have ONE item on screen at a time. If you scroll between one item and the next, the previous one leaves the screen, and the new one snaps into place. So if it were a photo gallery, each spot on the grid would take up the entire screen size, approximately, and would be flung out of the viewable area when you slide across to the next photo, in either direction. (Photos are just an example for illustration purposes)
This page gives a good summary of the different built in layout objects. From your description a GridView or possibly a TableLayout might work. GalleryView looks to be horizontal only.
I believe GridView is what you're looking for. Here's a tutorial: http://developer.android.com/resources/tutorials/views/hello-gridview.html
You should check out the ViewPager widget, which is available in the Android compatibility package. I spent a loooong time trying to get the Gallery widget to behave properly, but finally settled on a ViewPager which returned ImageView objects instead. Works like a charm.
