I have multiple screens in my app in which each screen has next and previous buttons except the first screen. when I click the previous button on 3rd screen it needs to go back to the 2nd screen and when I click next button on 3rd screen it needs to go to the 4th screen. In addition to it, the data of the screens need to be saved i.e. when I clicked the previous button on 3rd screen then the 2nd screen with already filled should be displayed. Similar with the next button also. Can anyone help me to implement this?
Thank you.

forms app I have four screens namely main screen , screen 2 ,list screen and settings screen so main screen is the entry screen and screen 2 is the one where all the operations are performed here and from here I can navigate to list screen and settings screen ,there is a close button in this screen 2 on click of it ,it pops back to main screen .so when I click on back button in android from main screen it takes me back to screen 2 instead of exiting from the app and on the click of back button again it takes me to list screen ,so can anyone please guide me how to tackle this back button activity ?
I would like to create activity in which it would be explained how the app is supposed to be used. On a click on a button, I would like an Activity to be opened which has next and previous buttons on the bottom. So the first screen after the click on a button would show the first instruction and you can press next to see the next instruction which opens a new screen. After going through all the instructions, I would like a Finish button to return back to the main activity.
My question is can this be made in a single activity or is it actually more activities that differ only by the text and pictures they contain?
Yes it can be done in only one activity(actually 2 if you include the main activity).
What you can do is have multiple TextViews, and when the next button is pressed, you can toggle that 1st instruction's visibility
. And so on for the next instructions. The Next/Previous buttons should determine what Textview is currently visible, so they can keep track what Textview to show next. Use switch statement
I have an app with home page showing a Google map with current location.
So according to the sketch in my home page i have a image icon or button type in my first screen and when i click on that icon or button a tile type opens up where there will multiple activities you can go.
Example if you click on 1 then it goes to one activity to do some task and if you click on 2 then it goes to another activity and similarly for 3 ,4 ,5 ,6 and whenever i click on any of the tiles it should go to particular activity.
I tried searching lot how to achieve this task over Google and thought some experts would me help me out with this in here.
And another point is home screen should not change if you click on icon or button in first image. As i mention in image both screen will be home page with map showing current location.
You can make it yourself. Set a RelativeLayout (in which there are six buttons) in the lower-right corner, and set it's visibility to View.GONE, then set another view in the lower-right corner as the button to open the expanded menu. When click on it, set the button to View.GONE and the RelativeLayout View.VISIBLE.
Hope it helps.
I'm implementing a not-so-standard navigational menu that is accessible from every screen in my app. That is to say, from every screen in my app, I can pop up a menu that will let me choose an entirely different area of the app to navigate directly to.
I have several screens that I call edit screens. They are screens where the user had chosen an item from a list of items and are able to then edit the data for that item. I do not wish for these screens to remain on the Activity stack if the user then uses the menu to navigate to some other area of the app.
This is easy enough. I can simply call "finish()" before navigating away. However, there are a couple places where it is possible to access a nested edit screen. Meaning the edit screen the user is currently on is a child of a parent edit screen. I want both off the Activity stack.
Can anyone think of a slick way to do this? The only way I can think of is to always use startActivityForResult and pass back some identifier that tells the screen to kill itself the next time it resumes.
I have a home screen with a Home button. This screen is the default screen when my application starts up. I would like to show the Home button as selected to indicate that the user is in the Home screen when my app starts. How do I do that? Please help.
Thanks.
I think for what you want to do you want to either use a group of RadioButtons, or tabs. If you just want a button that looks different in different states, try using a StateSelector.
