How can i touch move from one view(Imageview/any layout) to another without lifting the finger from the screen for triggering the touch listener of the 2nd view, just like Pinterest menu or Facebook reaction selection view?
If I've understood you correctly, it sounds like you need to implement a ViewPager component which will allow you to navigate various views seamlessly.
You can read about it here on the Android developer page: https://developer.android.com/training/animation/screen-slide.html
Hope it helps.

I have a custom grid view using Canvas component in my app. it works good normally but when i turn on Talkback the onkeylistener is not getting called and the navigation is not happening in android tv...while the same navigation works fine in fire tv..
do some one have idea why this might happen...
I have tried setting this.setImportantForAccessibility(IMPORTANT_FOR_ACCESSIBILITY_YES); while drawing the view but it did not help.
I want to show my custom floating button on all screen in my app without putting it in each activity.
Do we have some Global Activity like put a code once will show the Custom View all screen and hide/remove when app killed
I tried lot of things like Screen Overlay display over all apps
Please check code here - How to display custom view on all screen in android from my library
I've never tried to do it the Java/Kotlin way. But have you considered using Fragments?
You can declare xml layout and code for one Activity with a FrameLayout container and an FAB. The container holds all your screens and they switch between each other in the container. The FAB is on top and therefore will be displayed no matter the screen.
The Activity has a reference to any screen that might be displayed in it, so the FAB can behave accordingly.
Not sure if this helps. Perhaps if I see some pictures, I could suggest better.

Attached screenshot of netflix app with left side menu I am able to develop a side menu with customized icon and header in it. I want, when the focus comes on header fragment it should expand on top of row fragment, that is not collapsing the row fragment, the same as Netflix and hotstar are doing. How can I achieve it?
unfortunately, the HeaderSupportFragment used in the BrowseSupportFragment is not configurable enough to achieve this kind of design. Leanback is great to build quickly and easily media browser app but when it comes to "complex" design, it's easier to use custom component.
The major difference also here, is that the left menu of the BrowseSupportFragment show each rows header name displayed in the screen (that's why it's called HeaderSupportFragment). Here you want to show different entries like search, home, settings, etc.
To make this kind of view, I would suggest creating your own custom view and use a basic Fragment. I followed this tutorial which can be useful to handle menu open/close animation (I mixed it with a ConstraintLayout to simplify the animation and I made the menu overlap the rest of the screen instead of moving everything.)
See the tutorial: https://medium.com/building-for-android-tv/building-for-android-tv-episode-3-381e041dfec7
Some background:
Coming from an iOS background, using UITabbarController is very common and straight forward. Each Tab in the tab controller will change the current view to another UIViewController, and each of these UIViewControllers can have its own NavigationController (which kind of acts as a back stack). So whenever I switch tab, I would resume to the state where I left off.
Now I want to implement the same thing in Android, but it seems like the use of ViewController is different in Android. After digging around, I read that instead of using Activity like UIViewController, I should use Activity to act more like NavigationController, and use Fragments (which is deprecated)
to act as UIViewController instead.
However my question is:
Should I be implementing multiple Activities for Bottom Navigation? When I click on each item in the Bottom Navigation should I use an Intent to change Activity? Because from my understanding, using Intent to change Activity will add the new Activity to an Activity back stack, which would prevent me from switching back to whichever Activity I want. If someone could, Please tell me what is the "right" way (if there is one) to structure Bottom Navigation. Thank you all in advance.
You can use fragments as UIs, And Use a BottomNavigationView in your activity or you can use some libraries.
Here is a library for better customization: https://github.com/ittianyu/BottomNavigationViewEx

In Android you should use Viewpager, tablayout and Fragments. Just search for its tutorials. there are lots of them on internet
Just a simple maybe stupid question.
Is it ok to use multiple activities at once in an android application using an Inflater? I want to have multiple views on my screen without losing the previous view. For example, a user clicks on a button and a information screen shows up. Start Intent would convert the whole screen to the information screen activity.
Using an Inflater works but I'm just wondering if its the right way to display multiple views. Thanks in advance.
You should be using Fragments for this. Each fragment has a view/layout and you can move them in & out of your main view as you require. There are many tutorials
You can set the visibility of the views, e.g.:
Button b = (Button)findViewById(R.id.button);
b.setVisibility(View.GONE);
