I want to transform the upper left button that normally allows to open the Navigation Drawer to become a "Up" button (with the left arrow).
I looked everywhere but I couldn't find even a question where this problem is answered in a quick way.
Details:
I have a single Activity. The NavigationDrawer contains a list of elements. Let's call them Element1 and so on.
When I open the application I can see a "Home" Fragment that contains a sort of splash screen with some basic details of my application.
If I open the Drawer and select Element4 I switch the "Home" Fragment with the "Element4" Fragment. The icon at the top left should become the classic "Up" icon as intended in the Google developer site and allow me, touching it, to come back to the "Home" Fragment.
A simple example could be the NavigationDrawer application mockup created by Eclipse in its wizard. I want to modify it to make the 0 section the home section and if the 1 section its child.
Maybe if someone that knows how to do answer me it'll be a big help not only for me but for many other people.
Thanks

So I want to create a back button on every View I open in my Xamarin Android app. To explain better here is the screenshots, that will help me explain my problem:
Lets assume this is my first view when I open app:
When I click three dots popup menu opens. And for example I select Profile item.
Then this view opens:
Now as you can see at the top I have back button, but the text near the button is hardcoded... How can I make it show me previous view name? In this case it should be "List".
Moreover, I don't know how to implement back button to get back, and I was looking for any kind of tutorial or example, but couldn't find any... could someone please help me?
UPDATE 1
I am using MvvmCross in my application there are some places where I navigate between activities and some places where I navigate between fragments, I thinking about unifying everything and make navigation only between fragments...
For now I didn't made any implementation of back button, I need some help with that
I have a master detail page setup using Prism 6.3 pre-2, I've finally got it working as I expected for navigating to "detail" pages; so the hamburger button shows the slide drawer and I have a simple ListView bound to the ViewModel, I list some items, and I use the NavigateCommand to navigate correctly.
Now, the expected behaviour (in Android), is when you've navigated to other items in the slide-out menu, you should be able to use the hardware back button to navigate back to the very first "detail" page shown.
For example, say your app has this setup, and the items listed are Inbox, Drafts, and Sent. The default view is going to be whatever you decide is the default detail view, in this example, it will most likely be Inbox. So if I navigate to Sent, and then press back, it should go back to Inbox, also, if I go to Sent -> Drafts, and then press back, it should go back to Inbox, as this is the default starting point, if you then press back again, the app should exit. At the moment, using Prism navigation, no matter what page you navigate to using this setup, it will exit straight away.
Please note, I have set it up correctly, I essentially have something like this (as an exmaple):
await NavigationService.NavigateAsync("RootPage/BaseNavigationPage/InboxPage");
When I navigate to say another page like Sent, the relative URI is like so:
"BaseNavigationPage/SentPage"
Now, when back is pressed, it should go back to the InboxPage, I'm not sure how this can be fixed... Brain...???
In addition to this, there is one other unexpected behaviour that is missing.
If I want to show a modal page whilst using a Master Detail Page, it doesn't work as any app written by Google does... This is easy to see if you open any google app that has this layout. If you show a modal window for say Settings, it pops up, has the navigation title set and a back arrow, basically looks exactly the same as if you've navigated one step further down like:
"RootPage/BaseNavigationPage/InboxPage/EmailPage"
However, I expected this functionality to be available if I did the following:
"BaseNavigationPage/SettingsPage", useModalNavigation:true
If you simply play around with any Google made application you'll see these features, and these are what I expect and they feel natural.
Any help available to achieve this...? again...Brian...?
All of this should be simple, but it's proving not to be...
To get the behavior you are wanting with the NavigationPage in a MasterDetailPage scenario, you must create a custom NavigationPage that implements INavigationPageOptions and set the ClearNavigationStackOnNavigation property to false. This will kep the NavigationPage's navigation stack in place with each navigation operation.
As to your other "expected behavior" regarding modal navigation, your understandings about modal navigation are wrong. Modal navigation does not provide a software back button. Any time you want a software back button you must have the pages wrapped in a NavigationPage,
I have fitted my app with a NavDrawer following the Android Material Design spec.
But initially the idea I had for my App's Navigation Drawer was different, I would like to maintain that design, but I need advice with the approach.
I have uploaded an image of what I would like to achieve.

The user can click on button 2 and due to the nature of button 2, only that portion of the NavDrawer will slide out, or the user can slide the drawer out manually using a finger, and the drawer slides out and snaps to the edge of the screen just like the Android notification menu that u can slide from the top of your device.
Clicking on button four will slide the entire Group of buttons (due to the nature of content on button 4), button two would remain on the right if it were already there to start with.
Button 1 which would be the home button would check that all other buttons are in place (to the left) otherwise it draws them in then loads the home content into the main view.
I am not sure which way to approach this, using the Material Spec NavDrawer, or I custom design multiple linear layouts that follow the user's Xposition gestures.
Currently, I have a Material Spec NavDrawer, so the code is standard
Better to use the default Android Drawer Actvitity that comes with Android studio 2.0 and modify it.
it will save you allot of bugs
if you still want to create a cosutm one
you can either use what was suggested here >
http://simonvt.github.io/android-menudrawer/
or you can just choose one from this site >
https://android-arsenal.com/search?q=Drawer
it has some open library drawer helpers to help you write one.
i woul'd suggest against writing everything from scrach, it looks like allot of works and introduce allot of bugs, as to what needs to be on top of what every time, that you can fix by either using a library or taking the default one.
I have a news app.It is supposed to launch by swiping on the screen(homescreen or while in any other activity like switchr app).I learned to code swiping patterns but in my case I have to do exactly in the following way(swiping bottom right to top left)..Kindly have a look over following pictorial representation
1.Firstly app should launch by swiping bottom right to top left on the screen
2.next,show the user with list of scrollable arc menu buttons embedded in it like second image
3.when a user clicks on particular button it has to show a brief description about the content like third image
my problems:
creating arc like scrollable menu on bottom right side of the screen(I googled sia ahmed's solution over here ,it helped me a bit)
creating that parachute like structure(image 3) when user clicks particular bubble like button in arc menu..
please guide me
For the menu check out arcmenu by daCapricorn on github. Also see this question.
The balloon bit is trickier. I know of a balloon hint code for android but i haven't seen it in action.
Hope this helps!
I am an android newbie and I am trying to create an Android App with three Activities: a Homescreen, a listview and a detailview.
I integrated J. Feinstein's Sliding Menu in my Homescreen and filled it with a ListView to display my different categories (Restaurants, Bars, Culture, whatever). When I click one of my List Items, the new Activity gets created and Pops up. However, I want the Activity to replace the old one while the SlidingMenu stays on top and then gently slides away. I saw this behaviour in the Example App but I cant quite find the bit of code that holds the answer to my question. Hope anyone can help :)
The sample app uses fragment transactions instead of starting new activities to change the content. As far as I know, that is the only way to do the two actions – close sliding menu and change content – simultaneously.
