In android, i want to move from current to previous activity by left to right swipe as in iOS. I want to be able to even hold while swiping such as both activities are visible at the same time.
I want to introduce transition/animation effect just like in Telegram app. So please help how can i do it.
Tutorials or example code will work for me.
Thanks in advance!
You better use the Swipe animation with multiple Fragments inside one Activity: Creating Swipe Views with Tabs
take a look at this tutorial : HOW TO IMPLEMENT HORIZONTAL VIEW SWIPING WITH TABS
If you're already using Google's NavComponent library, you should try a library that I wrote:
https://github.com/massivemadness/Fragula
It's fully integrated with NavComponent, which means the navigation API stays the same, you only need to make some changes in NavGraph and NavHost container.
Here's the result:

I have an application designed by Navigation Component. In my app, i have one MainActivity include a nav_graph (called main_nav_graph) has a lot of fragment. My fragments use navController.navigate() and navController.popBackStack() to move between them.
Now i want to make a feature that i can swipe (from left edge of device screen to center horizontal screen) to back from current fragment to previous fragment. Ex like telegram or slack.
I was research for this a few times but i didn't found solution for myself. Anyone can help me?
Navigation library
I wrote a library fully integrated with NavComponent. It's exactly what you were looking for. Note that it works only with fragments, so it is not possible to achieve the same behavior with activities.

I'm trying to implement a "swipe" animation when opening a fragment.
Right now When the fragment is being shown from my MainActivity the fragment is being scrolled down (top-to-bottom), going over and covering the Activity.
What I'm trying to achieve is that instead of the fragment being rolled on top of the activity I want it to "push" the activity out of the way on its way down. Similar to how ViewPager animations work.
Here is a rough sketch of what I'm trying to achieve
From my limited experience with ViewPager, it can be used to "Swipe" between multiple activities OR multiple fragments, and you cannot mix & match.
Does anyone have an elegant solution on how to achieve this?
I really don't want to convert MainActivity into a fragment because there are tons and tons of code there.
Thanks in advance <3
In this case you need a BackDrop component.
for more information see the website below:

but there is no proper implementation in android you must implement this component by your own
you can use these website below to implement this component

I have a design for an app that will have a row of buttons below the action bar. Each button will open a different fragment. I am aware of ViewPagers, but I do not want the swipe between fragments functionality. I know that I can disable this functionality, but at that point is it worth using a ViewPager? I know this is a pretty common design paradigm, so how do most apps handle this sort of thing?
It seems like the ViewPager will provide some nice functionality out of the box, like switching between fragments and what not. So, I am leaning towards using one, but was hoping someone could provide some feedback on this approach.
Thanks!
Keep the buttons in the layout of your main activity. Have them call a function lets say loadFragment(Button button) on click.
This function then handles switching of the fragments, and you can change the display of the navigation buttons inside this function itself to highlight the appropriate button or something equivalent.
Google Design is always worth the reading.

Personally I have used ViewPager with tab layout for swiping purpose and it makes it easy to me to synchronise the transitions ( tabs and pages) where I put a red circle to the tab corresponding to the viewed page. With this approach I got a clean separated code.
I am quite new to Android development and would like to know how I can realize the effect that individual Fragments can be simply swiped away as it's done in the Android Chrome browser's tab overview. What do I need to google for?
Currently I have a Navigation Drawer as side-menu and a LinearLayout for the main content with a ScrollView inside, where multiple small Fragments go into.
The fastest and esaiest way to achieve that is to use ViewPager.

To do that, simply apply a gesture detector on the view you wish to swipe. When you detect the gesture, run an animation to move the view off to the right or left and then make it disappear.
I'd like to make a view in my Android app that flips between multiple views on a swipe/fling. I'd like it to behave more or less like the Android Launcher behaves when flipping between views. In particular,
It should flip views on swipe.
Generally a swipe will flip between one view and the next. It should not fling across all of the views.
If you swipe slowly, you should see the views dragging as you're swiping, eg. the way the Launcher does it.
I tried using a ViewFlipper with a GestureOverlayView as per Romain Guy's blog post here, but there's no indicator to the user as they're swiping. This makes discoverability difficult, which is presumably why Launcher does it the way they do.
I tried using a Gallery object, but when I swipe from left to right, there's a certain amount of momentum that flings the users through all the views rather than just taking them to the next view.
Is there a good way to accomplish what I'm trying to do?
I know this is an old question but ViewPager is created for this exact same purpose. ViewPager is part of android compatibility package and more can be found at http://android-developers.blogspot.com/2011/08/horizontal-view-swiping-with-viewpager.html
Take a look at HorizontalPager. It's actually based on RealViewSwitcher, which in turn is based on the Android homescreen's code, and supports snap-to paging with drag feedback, as well as nested vertically-scrolling subviews. Gesture support for fast swipes isn't all it should be, but this may get you part of the way there (and I'd welcome contributions back).
EDIT: As of 2012 you're much better off using Google's ViewPager - it's in the compat library.
Check out SwipeView within this project https://github.com/fry15/uk.co.jasonfry.android.tools It does exactly what you want it to do and is super simple to implement.
#CommonsGuy extended ViewFlipper to do it.

Ihaven't used this one yet so im not sure if it moves with your finger like the launcher if not your going to have to make an OnTochListener to do it for you in me.ACTION_MOVE you will update the view to change its position. I'll post some sample code when I get home if you don't get another answer.
