If I try and create a new project with a tabbed activity, no tabs show. Call me crazy, but I'd actually like tabs on my "tabbed activity". I searched on Youtube and it seems tabs just come up for others. Did something change with the newest version of Android studio? How do I add actual tabs and where do I edit the contents of the 3 fragments I want? This seems more confusing than it needs to be. Thanks.

I want to make something like this in my android app
With 2 or 3 activities or more. I don't want to use visible tabs with names. I just want when i slide through a new activity with its own layout appear, a totally different screen. I've read about viewpager and pageradapter, but i' m a little confused. What do you think is the best way to do it?
This is what you need, just follow this tutorial http://www.androidhive.info/2015/09/android-material-design-working-with-tabs/
You dont even need multiples activities.
You can actually create a swiping activity in android studio.
Goto:
File -> New -> Activity -> Tabbed Activity and choose Navigation Style to be Swipe Views.
Android Studio will do the rest. Then you can change the fragments according to your need.
EDIT:
This is a nice example that demonstrate using Activity with ViewPager.
Android PagerView between Activities
I've been working on a school project in a course for Mobile prototype for a couple of weeks when our mentor said we should change our way of navigate in the app.
Before the app started with a simple menu where the user could chose which feature to open, which could be different activities, listactivities, mapactivities, activities with custom views, ect.
We then found the ActionBarSherlock library which could help us make a nice tab bar. But should we then change our activities to be fragments (supportfragments runs 2.3.3) or can we keep it as (normal) activities? if so how to best show this under each tab.
Actionbarsherlock have been implemented successfully in our apps start activity and now we "only" need to make the navigation to the existing the activities or change them to fragments.
Do tell if this isn't clear what have described or you need any further information.
If you wish you can only use Activities with ActionBarSherlock
It all depends on what your want to achieve and the use of fragment might help you making a cleaner app.
Actionbarsherlock sample:
1° tab bar with fragment & viewpager
2° tab bar with fragment
I am newbie with fragments and actionbar in android.
I want to develop application for tablets which has multiple tabs, each tab has Listview in the leftside and the details of the item on the right side
Here is an example of what i want to do.
I don't know which of this is activity and which is a fragment and how to navigate using this tabs and change the content of the listview and the details.
I want examples to navigate using tabs with multipane layout because I searched about that and I found tabs are using fragments and multipane is composed of two fragments and nested fragments not allowed in android.
And I want to know: What is the difference between activity and fragmentActivity?
Fragment Tutorials
Google "android fragment tutorial" and you'll get a lot of results like this:
http://www.vogella.com/articles/AndroidFragments/article.html
Don't stick with only one though because many of them vary just slightly and if you do two or three then you'll have a better understanding of how fragments work (standalone or multipane).
Fragments with Tabs
A great way to see an example of switching fragments is by creating a new android project in Eclipse using the latest ADT. Create a new Android Application Project and when you're setting the name of the main activity you have an option to set the navigation type. Choose tabs or tabs+swipe. This will generate a clean project for you to see the very basics of how to switch fragments using tabs.
Activity vs FragmentActivity
Essentially, an Activity may contain a layout with no fragments and a FragmentActivity may contain a layout with fragments. This answer has a few more details: Difference between Activity and FragmentActivity
I'm new to Mono for Android, and I'm trying to port an old application, and I'm having difficulties with TabHost ...
In the tutorials page Xamarin writes:
"You can implement your tab content in one of two ways: use the tabs to swap Views within the same Activity, or use the tabs to change between entirely separate activities.
In this tutorial, you'll create a tabbed UI that uses a separate Activity for each tab."
Someone can help developing something "use the tabs to swap Views within the same Activity"?
Thank you
Now you have tabs on the ActionBar, and your "content" zone will be made of fragments.
Follow this link for further explanation and tutorial on how to add tabs to your app:

so I wanted to implement tab views on my app.
But I realised the google tutorial on tab views is broken and TabActivity is deprecated.
I tried inserting the tabhost element through the Graphical Layout but it won't even show up when my app starts.
It's just a blank screen.
What am I supposed to do/look for? I'm kind of lost here.
Thank you for any help/input.
As you can see from its docs, TabActivity has been replaced with Fragments. Here's a sample project.
