I started off with a black activity and whenever I try using Android studio, I get stuck in this screen. I cant drag any widgets, enter any text, or make any changes to the user interface. Is there anything I am missing? I downloaded all the Android Studio bundle and I have all the required SDK tools. I have attached a screenshot of what I am currently stuck with.
A screenshot of what I am seeing:
Recently I encountered the same problem myself. After some research I found that you must now use the "content_activityname.xml" file in order to edit the ui of an activity.
In your case this file is located in the layout folder, right under your activity_main.xml in the picture provided.
According to this thread: What is the role of content_main.xml in android studio 1.4? the main.xml now contains the global look of the ui, and also contains the content.xml file which again contains the components of the ui.
You should think of uninstall and reinstall Android Studio and after that creating a new Project. You also are able to look at some tutorials created by the creators of AS. They can be found at Android Developers.

At developer.android.com I found a tutorial called "Build a simple user interface". Unfortunately, it is based on an older version of Android Studio. It tells the user to open activity_main.xml. If one does this, the user cannot find the right icons in the toolbar. I searched and someone said open content_main.xml instead. This indeed posts the right icons in the toolbar, but as one continues in the tutorial, more and more errors appear. My question is: Is there a newer Android Studio User Interface tutorial that is appropriate for the latest Android Studio, version 3.6.1?
I really want to learn how to build interfaces via Android Studio and not clumsily play directly with XML code. Thanks for any ideas!

My situation is: I once made an android project(2.2 version) but soon needed to format my computer. After formatting, I downloaded eclipse again but when I imported my project, I wasn't able to use the 'graphical layout' menu for xml. It doesn't show me anything like the picture below.

I cleaned the project and updated the Android SDK, however, none of these seemed to work well. What could be causing this?
Try restarting Eclipse. Usually that solves the problem for me when that happens.
Right click on your layout xml file and select Open With -> Android Layout Editor. It will force eclipse to open file in android's layout editor mode
None of above worked for me. what worked for me is:
1- Select a Google APIs Project Build Target rather than one of the Android X.X ones. This setting is in right click on project -> Properties->Android.
2- Make a change in XML and save it. Now switch back to "Graphical Layout" and it will show the layout.
For some, only 2nd step works.
This Question was asked 3 year ago, I am sure that you have get your solution, however i was also facing the same problem but got the solution in eclipse, here it is:-
1)Goto help->AboutEclipse->Installation details.
2)check the version of Android DDMS, Android development tool, Android hierarchy viewer, Android native development tool, Android trace view and tracer for openGl ES in installed software tab.
3)If they have different version than you have to update all of them.
4)Goto help->check for update in eclipse and follow the instruction.
5)Then restart eclipse.
This solve my problem.
The topic seems a little bit cold, but I wanted to add it nonetheless.
I had a similar problem with my layouts recently. When i create a project it automatically creates the layouts in the latest version of Android (eclipse shows it as version 22 of android as of today). But i can't see anything. So i just change the version to, say 18, and it shows ok. Furthermore if i want to change it back to version 22 it throws and exception, saying that a class can't be instantiated. (I am probably missing a class or a library on my system.)
Therefore if you cant see the layout it might be a good idea to switch back to earlier versions for development. cheers.
I had a HD hardware failure the otherday and have been trying to recreate my Android programming environment.
I have installed Eclipse and the Android SDK. I have updated the SDK to the latest version.
I then imported my project from my backup folder. When I look at my layout files in eclipse I cannot view the Grphical.layout as its not an option. I get the following tab options for the page (Design or Source).
However my old environmet which i have a copy of in a virtual machine gives me following tab options for the layout file (Graphical Layout or filename.xml)
Any ideas why this is occuring? I assume it must be something to do with eclipse not realising that its menat to be looking at android xml layout files.
Please help,
Iain
comic if graphical layout is not showing by opening the xml file try using OpenWith ->Layout Editor on the xml file witch u want to open from project explorer under res folder
If the above answer doesn't work and if you cannot see the option of 'Layout Editor' on right click, restart eclipse. Worked for me.
sometime graphical layout show.but nothing showing.only blank.this is happen because the manifest minimum sdk is not support to view the layout.to resolve that change the api level which display in the right corner of layout display area.
I tried the option suggested by Muni, but did not work. Then I noticed that the Android version in the Graphical Layout was higher than what I had selected for my project which was causing the issue. After setting it to appropriate version it worked fine.
I had same problem with ADT eclipse. Probably this happens when you change something with your editor like changing themes.
Need not to worry about this, here I have solution for your issue it to navigate with your xml sourc and xml Layout files as for displaying Graphical Layout use this keyboard shortcut.
Shift+Alt+F7 and for navigating with source editor of xml file use this shortcuts as Alt+F7 Thanks for such good question. hope my answer will useful for all those are stuck with this.
I was facing this problem but that didn't get corrected by restarting.
Actually, my xml file say "MyFile.xml" was present in a sub folder of layout and in the layout folder itself(root).
When i opened "MyFile.xml" from the subfolder it just showed the code.
When i opened "MyFile.xml" directly from the layout folder(not from itz sub folder), it showed both the design and code.
:p
that was my blunder!
Just follow this pattern :
Package Explorer ---> res --> Layout ---> activity_main.XML
Open activity_main.XML
May 2013
just open with regular xml editor and put them side by side. 'right click' open with xml editor, and drag it so the windows layout side by side.
My problem was that I installed everything and restarted eclipse. But I didn't go back to.
Window | Android SDK manager.
When I did that I saw that eventhough I had installed everything and the SDK worked just fine. There was another 3 packages left to install. I installed that (and some sample code). Restarted Eclipse and everything worked like a charm.

This solve my problem.
From the upper right corner try a different "Android version to use when rendering layouts in eclipse". (Small green android icon). This worked for me.
If you can't see "Android Layout Editor",
right click on an xml layout file and choose Open With | Android Common XML Editor then choose Graphical Layout tab.
See here
If the above solutions doesn't fix the problem , then remove the very first line that is autogenerated while creating the xml file
and select some theme like "No Title Bar" or other.
Your problem will be fixed.

MY PROBLEM SOLVE
I just update my ADT and when I try to see layout in an old project I get this message
"LayoutLib is too recent. Update your tool!"
what does it mean? what is LayoutLib?
You'll need to upgrade your ADT Eclipse plugin to the latest version. You more than likely updated your SDK tools, but didn't update the plugin along with it. See these links:
Can't preview Android XML layout - LayoutLib is too recent. Update your tool?
http://code.google.com/p/android/issues/detail?id=17369
If it's still broken after you update, try this:
Right click on the layout xml file in the navigator (package explorer) and
choose open with > the "Android Layout Editor" from the list.
If it's still not working, try some of the other Editors from the list before you choose the Android Layout Editor again. this worked for me;-)
My role as the marketing man was to edit the layouts of the app screens to make them prettier, using the Graphical Layout of Eclipse. As a complete technical dodo, I was working under technical expert direction, but one day when he wasn't looking, I thought I could be clever.... I couldn't.
Like the others on this thread, I couldn't see the graphical layout tab and spent several hours in following the recommendations, updating various SDKs, ADTs etc etc. without remedy.
The solution was simple.
In being 'clever',I had moved the files I wanted to work on, from their position in res/layout to a new folder 'To be edited'. I planned to complete them there and then move them back into res/layout.
Unfortunately, I didn't realise that Eclipse is expecting to find layout files in res/layout (and why not?).
So I moved one file back into res/layout and bingo! Up came the Graphical Layout tab.
Recommendations:
1. Do not allow marketing people near Eclipse.
2. Provide an upgrade to Eclipse especially for marketing people. When run, a screen appears that says..'Make lunch for the technicians..'
After updating (to the just released updates) a problem occurs: I get an Error message "Unsupported Content Type in Editor"
The quick error dialog say's that the layout xml is 'illformed'. Not sure that has anything to do with it (as these all worked before). If I click the link in the dialog panel and make an association - same problem occurs (even after rebooting Eclipse).
When I expand the layout xml to the full list of errors, the top two errors are:
org.eclipse.core.runtime.CoreException:
Error opening the Android XML editor.
Is the document an XML file? at
com.android.ide.eclipse.adt.internal.editors.AndroidXmlEditor.createTextEditor(AndroidXmlEditor.java:617)
Any ideas ??? Obviously I can't open it to see what the 'illformed' issues are and, ALL these projects worked fine before the update...
UPDATED
If you experience the same/similar problem, add to the list at http://code.google.com/p/android/issues/detail?id=15003
The Problem follows but, here's a Workaround that worked for me: Make the association of the xml to the Android Layout Editor via Eclipse Pref's - associating them from the problem dialog doesn't appear to work. Then, restart Eclipse. This is a project per project needed change.
I had the exact same issue today. I'm assuming that you've done it already - but just in case - a restart of Eclipse made the issue go away for me.
Im posting here to other users know how to fix this issue. A simple way to get out of the problem for now: rename the XML file you want to see and the Android Builder will recognize the XML file.
i had the same problem after updating to latest SDK (honeycomb). It happened only on existing projects loaded into eclipse but not on new project. My solution was to delete the project first (do not delete the project source code) then import the project again, it works perfectly.
open that xml file in another editor and put the following line in start:
<?xml version="1.0" encoding="utf-8"?>
That problem is the result of the newly installed plugin. Uninstall it!
