Android :: Changing Screens - Switching Between Layouts
Jun 1, 2010
I am trying to create an app for android 1.5 which would be organized around 4-5 'screen's that will be changing in a given order.
So I start ma app with the first screen, which it's background and a button. When I click on the button a new screen appears with a different background and different options which lead to next screens. Sth. that is usually seen in games. The problem is that I need to pass a lot of data between those 'screens' like and array with recorded sound. My idea was to create a separate xml layout file for each screen and change the context in the activity class so ie:
CODE:............
A simple test app for 3 screens works this way but my I don't really like this approach and it seems to be inappropriate.
Is this the correct way of organizing such an app in android or should I take another approach - if I should, please give a more detailed advice on how to do this.

I am getting my feet wet developing software for the Android. My test app will have multiple screens (each having their own layout file). The main screen will direct the user to view the other screens based on user input. I kinda see this as layers of cake. Bottom layer being main; then you add and remove layers as the user makes UI inputs. The crazy trouble is how to view a second layer. I have created a second class which has its own onCreate method, which has its on setContentView(R.layout.secondlayer).
This class extends Activity much like my primary class does. I have a click event on a button within the main layout. This button will instantiate the new second layer class which I have done. And that is where my story endsI don't know what to do from this point. This is surely a newbie question If someone has an example that would be extremely helpful teach me to fish and I will be on my way.

I'm trying to create an app that offers the user 3 different kinds of layouts. The only common portion for all 3 would be the TextView (located at the top) that would display information specific to the currently displayed layout and 3 buttons to select the required layouts.
Is there some way we can create this UI in XML to keep only one constant part(the upper TextView) and dynamically display any one of the 3 layouts below it?
Would it be better to create separate XML's for each of the layouts (each including the upper TextView in them)?
OR would doing this via code be better?
Fast switching between the 3 layouts is important. TIA
[EDIT 1]
Actually they are 3 different layouts, with several "child" layouts and views within each of them. Could a ViewFlipper be used for switching between these? I was thinking that a ViewFlipper was only for switching between View elements?
I do have them in individual XML's right now but am looking for some way to load and unload them fast. Not sure how to do the hiding thing, will try reading up on that. [/EDIT 1]

Just had an issue today with the phone after I got off of NYC Maximas.org and went back to the home screen. The phone decided to have a mind of its own and was actually switching between screens itself. Every time I hit the home button it would switch to screen 2 and three and so on and so on. Also when I tried to text right after that I was unable to input text for w.e. reason. After a shut off and turn on of the phone the issue was resolved; "weird". Anyone else having this problem?

Just starting to play around with the new X. I tried the car dock on my first trip with nav without having the charging cable plugged in. Nav seemed to stay on the turn-by-turn screen just fine, except that the screen kept timing out (as expected running on battery). Today I also plugged in a charging cable. Nav started out working fine, but then several times during my trip the X inexplicably switched away from the turn-by-turn screen to the directions screen (or to the "maps" top-down screen). I didn't see anything in the options, and can't imagine why the thing would be switching. Also, I just updated to the latest Google Maps application (last night, between the two nav tests), so maybe that had something to do with it....

Just read this from another thread thought root users would like to know you can save your screen setups now. I figured this will save me about 30 minutes each time I change a rom. I tried it out and it worked great. With all the ROM's I like to try this will make me change from L.P.

I'm not looking for exact code here, just a direction on what to look for and what I should be reading about so I can figure this out. I have a layout that I would like to remain static, with only the listview changing depending on what's selected from the list. I've reloaded data in the list, but I would like the fancy transition animations between choices, and would like the app to go to the previous menu when pressing back.
Someone suggested using a viewswitcher, which seems like it'd be great, but I am still unsure about how to fill a listview in a layout with a regular row layout, then on selection do an animated transition to a custom row. Also, it seems the viewswitcher is limited to two views, so it may be a limitation when I want to go a few menus deeper. Preferably, I'd like to put each menu in it's own class so that I can handle filling it in that class, if possible...

So what is going on after the last update? My phone randomly freaks out at times and starts switching screens and stuff on it's own. Seems like it is possessed. Never did this before the update...and a friend of mine is having the same problem with their Incredible. Also at times I try to go back to the home screen and the screen goes completely black for a bit....then will eventually go to it. When it freaks out the only thing I can do is restart it and then it will work fine until the next time it freaks out.

Is there a way to get rid of, or change the home screens? Specifically the sprint music player page and the bookmarks page

I'm creating a game where there's a screen that, for the most part, is shared by four different activites - but a key portion of the screen will be completely different, depending upon which activity is active. Basically, on the left will be an image of the player and along the bottom there will be a row of buttons (let's say for Armour, Weapons, Magic, Skills). This leaves the top-right portion, which will need to dynamically change to represent the button pressed. (So, one moment the top-right portion is the armour selection activity, and the next it's the weapon selection activity, and so on.)
Is this possible? Can I have a layout within a layout and dynamically point the nested layout at a (nested) layout.xml of my choosing? Or, am I looking at just duplicating most of the layout four times (for the four different activities?) Or, am I going to be looking at linking the four activities to a (the top-right) view component, and then having to dynamically construct all of *that* view's child views based on the currently active activity? Well, that's about as much sense as I can make this question make.

I really like my Droid Incredible (Dinc), but I just noticed a minor glitch on it. When I was on the main home screen, the phone switched over to all three of the left home screens on its own (it switched to these home screens one after another). Do you know if there will be a software update that will fix this problem?

I am wanting to change the icons for a lot of my apps on my home screens. I have been looking at BetterCut, Apps Organizer, and Folder Organizer. Now Apps Organizer is free and Folder Organizer has a free trial version, but Better cut is not free not does BetterCut have a free trial version.
Please tell me what you like/dislike about the apps, primarily BetterCut and Folder Organizer (paid).
*How do they run?
*Are there any major bugs?
Is it easy to change the icons for apps on my home screens?
*Is BetterCut really worth $2?
*Is Folder Organizer really worth $1.35?
Are any of these going to meet my needs of wanting to change the icons on my home screens?
*Are the icons dependant on the app that changed them (in other words, if I uninstall BetterCut after changing an icon, will the icon still be what I changed it to, or will it go back to the default icon)?
*If you had $2 and could only choose one of these apps to change the icons on your home screen, which would you choose?
I am going to play around with the two free versions of these apps and see if I like them, but unfortunately, BetterCut is an all or nothing app. I just don't want to feel like I wasted any money because the app ended up not doing what I wanted it to do.

My Eris has been acting up the past few days. It has been changing screens automaticly when I pick it up. Also when I go to type something it will move my placing backwards so I'm typing in between words that I've already started typing. I've tried rebooting several times. I'm not sure what to do with it other than take it out back and shoot it.

I had a little time with the captivate today and noticed it has 4(i think) horizontal scrolling screens for apps. What happens when you fill those? Does it automatically add another one or what?

If I first set the content view to my xml layout using setContentView(R.layout.main); and then add another content view using addContentView(layout, params), the content views overlap each other. I want the second content view to position itself directly under the first one. Is it possible or do I need to combine the xml and the programatically created layouts in some way? Both of the layouts are linear.

i have a layout folder with 2 layouts. layout1 and layout2 i have another folder layout-land that has layout1 in it. i would like to be able to get to all the layouts so i could create a set of layout like this: {layout1, layout2, layout1(from layout-land folder)}is there any way i can use the existing android mechanisim to do that? if not, what would be the impact of creating my own definition of the layout folder (for example to have under the layout folder layout1, layout2 and layout_land1 and have my code do getOrientation to diffrentiate whcih one should be presented).

I'd like to build an activity that is mixing layouts with 2D graphics. So for example, would like to introduce an edittext with an integer value and based on that value the size of a circle is dynamically adjusted and drawn. Any idea how to do this?
For plain graphics I am using this approach here - but how can it be expanded to cover Android layouts (buttons, editboxes, textviews, radiobuttons, etc.)?

Is it possible to create subfolders under res/layout and place the layout XML files there so that one can call a view like setContentView(R.layout.questions.create); or setContentView(R.layout.questions/create); ?

I've met a problem with animation when tried to make a View to perform the animation which should cross 2 layouts, e.g. make a translate animation so a view could move down to the TableRow below. This trick works fine when i try to move a view within a single TableRow but not when i try to move it up or down. I've also discovered that if i create a single RelativeLayout and apply the same animation there, it works fine, but i can't arrange all the components i need on the screen. Could anybody please provide me any hints about it?

supporting multiple screens (sizes and resolutions). I´ve searched not only this forum but many different websites and the android documentation but I´m probably doing a small mistake so things are not working properly.
Well, my main layout was designed with a HVGA screen, and it works great. When I try the same app on a WVGA, FWVGA, WQVGA or FWQVGA, I always get an unused space in the end of the layout because the screen ´s "heightnes" is proportionally bigger than HVGA´s.
So I consulted the documentation and decided to give a try on resource qualifiers, so I then created a nonsense UI and placed it on layout- large, created a new AVD using the WVGA skin and launched the app. Well, all I got was my old and not well stretched layout. The same happened to a FWVGA AVD.
This is the first problem. The second is: medium high density medium size screens and medium density large screens have the same resolution: how can I create a layout that is loaded for both, but not for (for example) medium size medium density or small size medium density screens?

I want to make a listview that has different rows (layouts). I will load the data from a webservice and it can be 2 or more layouts i have to generate then. I am creating a social network app and want to show a stream of the users activity. So when he made a comment, make a new friend, this all has to come in the same list.. I load 1 XML file with multiple different child objects (comment, friend) so i can see which layout i have to use........

i'm running into some issues inflating layouts and i wonder whether i have something basic wrong.i have a ListView with a custom adapter etc, and of course the item View is custom too. i've been creating the item View in code, and everything works fine, including recycling them and all that. great.but i want to move the View into a resource, where all good Android views live, and weirdness is happening.in the ListView's getView(), i get my inflater and inflate the view by ID. the view itself has its own XML file. i can inflate the top view, but i can't find anything by ID, and when asked for its children, nothing comes back.are there funky rules for inflating views this way? is there a convention for how this should be done inside a ListView?

Is it possible to load my main.xml layout file in onCreate() and then later in the app, switch to a new XML layout? I've tried placing setContentView() later on in the app but that seems to not actually set the new View because my references to objects in the newly set xml layout file are returning as null. I've tried doing some layout inflating using the LayoutInflater but I'm having no luck (I'm probably doing something wrong)... So is there any other way to swap layout xml layouts at runtime?

Is it possible to localize layouts (in the same way you can have a 'por' and a 'land' layout? As you may know some languages are less 'verbose' than others, thus sometimes layout adjustments might be needed according to the current language.

I'm wondering if it is possible to inflate a layout using a different density value than the default system density. I have a high density layout, which looks good on the Galaxy Tab (1024x600px, hdpi) and I like to use the same layout on another tablet with the same pixel resolution but medium density. The mdpi layout which is used works on the device but the screen just looks really empty and I would prefer to scale things up. So is there a xml argument for scaling the layout, maybe something similar to Bitmap.Options.targetDensity. Or could this be done with a new LayoutInflater class?
