I am trying to reveal the navbar only when touched at a specific area on the screen.
Is that possible. I was able to hide it. The problem is it could be revealed by touching either the top or the bottom.
If you want to get the navigation interface out of the way as much as possible, Sticky Immersive Mode is what you're looking for. The user can always swipe on an edge to bring up navigation, but it's transparent and your app will still receive the swipe gesture as if nothing had happened. Access to navigation is always there for the user so they can't be trapped in an app with no way out.
You can add buttons or other controls in your app to show or hide the navigation interface if that's still something you want to do. The Advanced Immersive Mode sample provided with Android Studio shows how.

So I'm a Note9 user. Lately, both Discord and slack updated their app to a new navigation system, where there is a toolbar at the bottom and you can swipe right and left from anywhere on your screen to see something like a hamburger layout. I guess this helped a lot after the new gesture system Android has implemented made it very hard to swipe to show the hamburger drawer.
My question is, can anyone point me in the right direction to implement something similar? I was thinking about a Pagerview, but I'm not sure that's what they're using.
I need to add an additional button to the right of the system buttons, as shown in the photo. clicking on it will perform a specific action related to my app. Can this be done?
In general: No. There's not an API for this, only the OS can control the navigation area. Consider also the problems you'd run into with the variety of system navigation styles available, many of which, like gesture navigation, don't even have buttons.
Some apps fake things with screen overlays that reimplement some or all of the navigation and/or hide the system navigation, but you're going to run into all of the above issues doing so, plus the issues inherent in screen overlays, plus you'll have no guarantee that however you do it will continue to work into the future. I wouldn't recommend trying this approach.
This is the screenshot from Google Play Music, and what's the name of the widget in the bottom of the layout?(circled with red)
When user swipe it up or click it, the cover page will show up, which can be closed by swiping down on the screen -- and that's what I need((XDDD
Thx.
Not sure if there's any standard by Android Developer, but I found this. It seems pretty similar.

In my application I want to prevent the display of the navigation bar. In Android 4.4 it's easy to implement (see here: How to hide navigation bar permanently in android activity?), but lower versions can't do this.
I saw a similar mechanism in some players which hide navigation bar in fullscreen without any possibility to display it when the screen is touched.
I would be grateful for tips or code samples as it can be done.
Thank you.
SYSTEM_UI_FLAG_HIDE_NAVIGATION is available since API level 16.
So it works since Android 4.1+. You have to remember to reset this flag every time the user makes the NavigationBar show up again.
Only the immersive mode is only available since 4.4
I am currently working on a calculator application for android. I am finding it difficult to conveniently take a screen shot of the app. So i have put my calculator on pause so I can write a simple screen shot app. It runs in the notification bar and when you click the notification the notification bar slides away and a few seconds later a snapshot is taken. This works perfectly. Now I would like to add functionality to take snapshots even for full screen apps. I have seen apps that put a sliding drawer on the screen onto of whatever app is running. That is there is always a button on the screen no matter what you are doing that when you click/drag it that sliding drawer came out. How did they do that? It should be a simple process to use a button instead of a drawer and when it's clicked hide it, snapshot and unhide it.
So my question bsically is
How can i put a usable button on the screen that stays above whatever app is running, even the homescreen
I realize I'm not answering your question directly, but if you simply want to get a screen capture of your application running, I would use ddms in your android tools directory. It has a menu option for getting a screen grab. I use it frequently.
Just go to Device > Screen Capture
