Android : Layout To Work On Various Devices
Feb 23, 2009
I would like to create an application that has 5 images, 4 of which are small, and one is larger. The 4 small images I would like to place in the corners of the screen, and the big image I want to be right in the center. Like this: http://www.eng.utah.edu/~jwilson/files/layout.png
What is the best type of layout to accomplish this? I would like the layout to work on various devices, so some kind of fluid method is preferred over absolute positioning. Seems like a table view would work if the images were the same size, but they're not.

I am using eclipse 3.5 with the ADT plugin.when I view layout xml files, i get two tabs in the view the source code view and a graphical view.the graphical view almost never works for any of my layouts.it usually shows "NullPointerException: null" at the top and nothing else. when it does work, it often does not match what i get in the simulator or device.it seems like this thing simply is not ready for prime time; although the idea is very cool.has anyone else had much success with it?

In my layout i need to have to 2 EditText widgets which would occupy 50% of area individually. I'm planning to have the solution generic for all devices, let me know if this can be controlled through XML in any way or I'll have to create the layout through code.

In past couple of days, users of my app have sent crash reports indicating errors in layout inflation.
"android.view.InflateException: Binary XML file line #27: Error inflating class java.lang.reflect.Constructor"
After some investigation I found out that all four of them were using the new Sprint HTC Hero devices. This error hasn't been reported on any other device/ROM nor could I repro it in the emulator.
I figured this is the kind of error that one gets if layout is too big or too wide. Although my layout is very well within the limits that Android framework puts, I split it further and asked the users to test. However, even with this fix the users are seeing similar crash while inflating the layout.
How I can proceed to fix/workaround the issue - given that I don't have access to any such device?
Following is the detailed stack trace of the crash:

I have some media (Audio tracks) on an app.With file path 'R.raw.test'.I use some code to get it into a mediaplayer: MediaPlayer.create(Textbox.this, R.raw.fly);
And it works PERFECTLY on the Android Emulator...(Plays track on click of button)Can someone explain why, when I put it on my Archos (5 IT) it doesnt work at all? As soon as the button is clicked, it crashes.Do you have to do something to file paths or what?

Happy droid user on Nexus One. Thinking about playing around with one of those cheap android tablets. If I logon to that tablet with my google account, will it mess up my N1 and existing account/settings? Also what happens with my apps? can I download the ones I've paid for again (onto the new device)? etc.

I am unable to override attributes when using <include> in my Android layout files. When I searched for bugs, I found Declined Issue 2863: "include tag is broken (overriding layout params never works)"
Since Romain indicates this works in the test suites and his examples, I must be doing something wrong.
My project is organized like this:
CODE:..............
The buttons.xml contains something like this:

And the portrait and landscape receipt.xml files look something like:

In Android when I am adding a view object like ImageView to FrameLayout view and then immediately trying to call layout() method to repositioned the added view object it is not working. But when I call the layout method alone after some new event e.g. touch event then layout() seems to work. This also happens when bringToFront() and layout() is used together, layout() does not seems to work together with other method. Is there any reason why is this like this? Also instead of adding view object in the middle of the screen can it be ADDED at some specific location in FrameLayout?

When I include <style> elements from /res/values/styles.xml the Layout designer/preview within Eclipse doesn't update with these styles, but shows as it would be without any styles.Can anyone confirm this issue? If so, Is there a way I can fix this myself easily? If not, where's the appropriate place to sumbit a bug report?

I am facing problem in running application with HIGH & LOW density with single layout(xml file). I have read so many threads and verified developers.android site too..
All mentioned to specify the size of the components should be in dp or wrap_content or fill_content, then android itself take care of the density use,since android is density independent.
And also to place the layouts in layout-nodpi folder for density free. Then in one of the thread, they mentioned to use
<supports-screens android:resizeable="true"
android:largeScreens="true" android:normalScreens="true"
android:anyDensity="true"></supports-screens>.
I also tried by placing the layouts in ldpi,mdpi,xhdpi and hdpi.But no use.
I have tried all the above,but i couldnt get the application UI same in two different density.. I am using "Funbook micromax"[Normal density] and "Intex iBuddy"[Low density] model, both are 7 Inch.
use single layout to be work in all type of density and screen size..

I am developing my am on mac (10.5.8), on eclipse and SDK 1.6 and a Vodafone HTC Magic Everything was working ok up to a few days ago. I can not see my device on adb devices. I also got a Sony Xperia and I can not see it on the list either. I upgraded the phone software (the HTC) to 1.6 a few days ago. Maybe that is what caused the change, but I could not be sure.

While developing for Android, I am unable to open more than one main.xml file in an Eclipse editor at a time.Each time I open one, it simply replaces the editor (tab) of the first main.xml with the new one, instead of opening a new tab - even if the contents of the existing tab were unsaved.Even stranger, I can open multiple main.xml files from different projects with no problems.This only happens when they're within the same project.

Is it possible to build a GridView object in XML with 3 columns and 4 rows of Image buttons? It doesn't seem to have similar containment relationship like LinearLayout or RelativeLayout viewgroups.
I want to do this entirely in an xml layout file. When I put ImageButton xml tags inside a GridView xml body, The layout panel in eclipse is throwing an exception: UnsupportedOperationException:addView(View, LayoutParams) is not supported in AdapterView.

I've successfully created a countdown kitchen timer activity, however my goal is to have an activity that has 3 timers on it that all work independently. I created a separate layout just for the timer itself and moved the timer code into a class and I've used layoutinflater to create the views and then added them into the linear layout for the activity. I get the layouts fine, however there's no functionality. There doesn't seem to be anything that ties the class code to the activity. How should I approach this? Can anyone point me to some working example code?

Imagine I have a toolbar implemented as a horizontal LinearLayout as follows:
[___Button1____] [___Button2___] [___Button3___] [___Button4___]
When someone clicks on Button2, I want the toolbar to change to:
[___Button1____] [___________Button2___________] [___Button3___]
The toolbar should transition from the first state to the second state through a smooth animation. I would like to use a scale animation on Button2, and while that is happening, Button3 and Button 4 should move to the right (while the animation is going on). At the end of the animation (or maybe during), I will fade Button4 out.
Question: How do I achieve an animation of the layout of the toolbar such that only one component (i.e. Button2) is being scaled while the others are not being scaled - the layout is simply updated during the animation of Button2.
I looked at LayoutAnimationController, but it does not appear to allow me to either:
1. specify different animations for the different components, OR
2. indicate that only animate one component and don't animate the others.
I can't scale the entire toolbar because that distorts Button1/3/4 which I don't want.
