Android : UI Design Suggestions For Display And Switching Between Multiple Layouts
Jun 26, 2010I'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]
Android :: Multiple Activites That Share 75% Of Layout - Layouts Within Layouts?
Sep 6, 2010I'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.

Android :: Layouts On Top Of Each Other
Sep 21, 2010If 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.

View 1 Replies View RelatedAndroid : Animation Across Two Layouts?
Aug 10, 2009I'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?
View 2 Replies View RelatedAndroid :: Different Screen Sizes X Different Layouts
Apr 27, 2010supporting 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?
Android :: Listview With Different Rows (layouts)

I load 1 XML file with multiple different child objects (comment, friend) so i can see which layout i have to use........
View 5 Replies View RelatedAndroid :: Rules For Inflating Layouts
Sep 28, 2009i'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?
View 11 Replies View RelatedAndroid :: Swap XML Layouts During Runtime?
Jul 27, 2010Is 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?

View 4 Replies View RelatedAndroid :: Way To Inflate Layouts With Different Density?
Oct 21, 2010I'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?

View 1 Replies View RelatedAndroid : Using Multiple Layouts For Different Screens
Dec 3, 2009I 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.

Jun 1, 2010I 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.

Android :: Use Motion Events With Multiple Layouts
Aug 22, 2009I'm beginning in android development, and I've stumbled upon a problem. My application has different layouts stored in xml files, and I use motion events such as onFling or onSingleTapup. These motion events seem to apply whatever layout i'm in. My problem is simply identifying which layout i'm currently using so I can define the appropriate action. I guess what i'm trying to do is a bit like this:
@Override public boolean onSingleTapUp(MotionEvent e) { if(using main layout) { //do this } else if (using settings layout) { // do that } return false;
}
Android :: Best Practice For Viewflipper Containing 10 Linear Layouts?
May 23, 2010I'm embarking on a GUI Activity composed of a viewflipper, which I would like to contain 10 linearlayout layouts. Is it advisable to put all of my layouts into the same XML resource/layout file? If not, is there a more organized approach to coding a viewflipper with many layouts? Will having everything in the same file come at a significant performance cost?
View 2 Replies View RelatedAndroid :: Tab View Initialization - XML File Layouts
Jul 2, 2010I have a problem with a tab view on android. I am using 4 xml layout files (each a RelativeLayout) as the content for tabs in a tab view. The main.xml contains: TabHost (@android:id/tabhost) containing a linearLayout which contains a TabWidget (@android:id/tabs) and a FrameLayout (@android:id/tabcontent). If I embeded the multiple one after another in the in the main.xml everything works fine (except my main.xml is unmaintainable which is the problem I want to solve by splitting the files into a simple main.xml which defines the tab and the content frame and then push the views onto this). The code I have to inflate and insert the 4 RelativeLayout xml files into the tab content is as follows:
mTabHost = getTabHost(); View wv = null;
wv = LayoutInflater.from(this).inflate(R.layout.user_tab, mTabHost.getTabContentView(), true);
mTabHost.addTab(mTabHost.newTabSpec("User").setIndicator("User").setContent(wv.getId()));
wv = LayoutInflater.from(this).inflate(R.layout.track_tab, mTabHost.getTabContentView(), true);
mTabHost.addTab(mTabHost.newTabSpec("Track").setIndicator("Track").setContent(wv.getId()));
wv = LayoutInflater.from(this).inflate(R.layout.chart_tab, mTabHost.getTabContentView(), true);
mTabHost.addTab(mTabHost.newTabSpec("Chart").setIndicator("Chart").setContent(wv.getId()));
// And so on for the multiple tabs.
When I run this the first tab (User) is empty and the remaining tabs have all the content from all the views. So tab2 has the content from tab1-4, tab3 has the content from tab1-4 and tab4 has the content from tab1-4. Returning to tab1 it then has all the content from tab1-4 now. The code works just fine, the events on the various objects in the views etc all are good. It is just that they are all muddled together in the view. What is causing this and how to correct it?

May 12, 2009I want to be able to make an imageview move from point a to b while going through several different views. For example, say I have a table layout, is there any way an imageview can move from the topleft cell to the bottomright cell? Everything I tried seems to indicate that an imageview will only be shown in it's own container - none of it's parents, siblings or children will show it. Is that correct? is there any way around it? like creating an overlay or a transparent canvas on top of the entire thing so I can do it?
View 3 Replies View RelatedAndroid :: View Hierarchies In Layouts Are Now Likely To Cause Crashes
Apr 24, 2009Having read http://android-developers.blogspot.com/2009/04/future-proofing-your-a... l I noted this little section;
"Due to changes in the View rendering infrastructure, unreasonably deep (more than 10 or so) or broad (more than 30 total) View hierarchies in layouts are now likely to cause crashes. This was always a risk for excessively complex layouts, but you can think of Android 1.5 as being better than 1.1 at exposing this problem..."
Will the SDK warn us when we're reaching the limit for crashes?
And more to the point why does it crash and not return some form of meaningful error to the app? With an error code or thrown exception developers could create various levels of layout complexity and step down the layout complexity level until they find one the device will support.
No matter what the post says I see this as a regression in functionality and I definitely do not see it as "Android 1.5 as being better than 1.1" in any way.

Android :: TabActivity - TabContentFactory - Inflated Layouts?
Apr 2, 2009I have an activity which extends TabActivity and implements TabContentFactory. For simplicity's sake I'll limit the problem to 1 tab.
In onCreate() I do this:
CODE:..........
In createTabContent:
CODE:...........
So far, so great. I get the tab, the layout is displayed.
I also have a button in the layout, so I do:
CODE:.............
And then I subscribe to it's click event:
CODE:..........
Now, here's the problem. I click the button and nothing happens. I can for example execute the following code from elsewhere:
CODE:.............
And the button will get disabled, but when I tap it (in its *enabled* state) - nothing happens.
If I'm not, could it be that I have another tab, where the another inflated copy of the same layout is displayed? However, in this layout's button's OnClickListener nothing happens as well.
