Everytime I follow a tutorial book or you tube video, I have also used the cheat help in eclipse. My programming always comes out with errors. here is one example why does all the tutorials main activity comes out showing linear layout and my projects default is relative layout. So how do I change the default to linear when creating new project.
I know I can open a new layout xml but all the tutorials opens a new project in linear.
I am a massive fan of android and I really want to make some apps, but all the tutorials never seem to correspond with the results I get and they all make it look so easy.
go to youre layout.xml
make sure to be in the graphical layout (check bottom bar)
top-right in 'outline' right-click on the relative layout
choose 'change layout'
choose youre desired layout, (linearlayout(vertical) probably in ur case)
I found it after digging a lot in Android Studio After visiting JetBrains and Intelij documentation and help sections i found nothing much helpful but i found way on my own, I had answered it here, With all explanation and screenshots.

I am trying to learn to make my own apps by following tutorials but i have an issue when i run the app in the emulator or on my phone. All theScreenshot contents of the layout are squished in the top left corner.
This is all the codescreenshot 2here. I am a noob so don't go to hard on me. Thanks
It would be better if you also post your layout code (activity_main.xml) here for this kind of problems. But I am guessing you are using constraint layout as root of your layout and its child views are not constrained vertically, so all of them go to another position in run time.
Maybe you are using a relative layout and no positioning is specified.
You should paste the xml's code
I've recently switched from eclipse to IntelliJ IDEA for Android development. I'm not missing any features, beside the rather helpful designer preview in eclipse. I populate certain views in my activities at runtime, there are no texts defined in the corresponding XML files. In eclipse, it looks like this:
It fills the empty views with placeholder text which is nice to get a rough impression of the layout without having to start the app. But in IDEA, the designer looks like this:
The views are empty, and it's difficult to even see them without selecting them in the Component Tree. I haven't found anything in the options, is this missing from IDEA or did I miss an option?
It's not possible right now, but it would be nice to have, I've created a new feature request, please vote.
I am very new to Android development and am having some trouble. I am creating an XML file using Eclipse, both the Graphical Layout feature is what I'm having trouble with.
Also, I am working in Android 2.3 for compatibility reasons.
I am wondering if there is a layout which enables me to place buttons or text fields or any attribute where I want to put them. This may sound stupid, but it seems that every layout has some sort of order in which it lets you add attributes, and whenever I try to drag them elsewhere on the layout things just get very very messy.
If what you want is an AbsoluteLayout, this has been deprecated since Android 2 (IIRC). You can try using the RelativeLayout, which let you position freely your widgets. Else, if you only use LinearLayout, then yes the widget will be positioned in a strict way.
use Relative Layout. I recommend that you read up on Android layouts so you understand why, what and hows of Android way. There are some good tutorials that I found helpful. TutsPlus: Android Layouts
There is also a very good video from Marakana.
Marakana: Android Bootcamp
If you are just starting out with Android check other tutorials/videos on Marakana. They are a very good resource for beginners.
Hi im just starting to make an app, and on eclipse i get 2 tabs. Graphical layout is one of them. I see a black cell phone screen and some buttons and text stuff to put on it. What is this for and how do i use it? Thank you
With the graphical layout you can just drag and drop items in, and the xml is the actual code. Adding things via the graphical layout will edit your code for you, and visa versa. Personally I prefer to just use the xml because the graphical layout can be a little difficult to get the results you want, and it's always useful to have a good understanding of the xml code and how it works.
Android uses XML layouts. They can be a real pain to edit. The graphical layout tab with the picture of the phone is supposed to make it a little easier.
Sometimes you still have to dip down into the XML to get things just right, but the graphical layout will at least give you a preview.
It's your Interface Builder.
It builds interfaces ;)
Working with Android for the first time, I've blocked out a layout using the relative layout and laid down some buttons and text widgets how I like them. However when I go back to rename the IDs the layout goes all crazy moving elements around and in general destroying the hours of work I spent laying them out.
Does anyone know how I can rename the widgets without Android destroying the positioning for widgets in the Relative Layout? Is this some "feature" of Android? I can't imagine why it would be hard for the UI builder to handle simple renaming of a widget ID without destroying the positioning information.. Do I have to use an external text editor and modify the XML files directly? Ughh I hope not.. I'm using Eclipse IDE.
You can use find and then replace all to change the names every place that they appear. Shouldn't take anywhere near an hour if you're dealing with a small layout.
In general the graphical UI creator that is currently included with the Android SDK is not so great for creating anything but very simple layouts. In my experiences (which were a long time ago, it may have gotten better since) it was terrible with RelativeLayouts.
If you have not modified your xml directly then it is time that you jump in and start learning to do it that way. You'll find that you have a much greater level of control over your layout, and once you get the basics figured out you'll probably be able to create quicker using raw xml then with the graphical tool anyway. I do wish that there were a nice GUI creator for android out there, the best one that I've ever come across is Droid Draw which I found to be better than the one included with the SDK, but still not as good as I was hoping.
To modify the xml directly you don't need any additional text editors, you do it inside eclipse. Open up your layout file and at the bottom click on the tab that says "Source" when you want to switch back to graphical (good to see the changes that you make to the xml graphically) just click back to the tab that says "Design"
