[Layout screen as an bug example1While developing my android app I deleted linear layout by selecting it in layout manager by mouse and pressing delete button after that android studio stopped giving me auto complete code suggestions in XML also layout manager is not showing all attributes associated with with a UI component Please guide me how to fix this issue
The xml code might not be in proper format, like missing any closing bracket or something else, first you should check that.
Other steps to try:
Build -> Clean Project -> Rebuild Project
File -> Invalidate Caches and Resatart
File ->Manage IDE Settings -> Restore Default Settings (it will reset your IDE, as if it is newly installed.)

I've this buttons in a particular order,but once is loaded in the activity the order is not the last i've edited but remain the previous!
Why in the editor of eclipse is correct and on runtime is different?!?
Thanks!
Sometimes a clean and rebuild is enough to solve your problem. Also you will get a warning on your XML preview that you need to build your project if you changed any code in a custom view for it to draw it properly.
Uninstall previous app from your android device (if compiling from android device).
Then Go to Project->Clean . Then run your project .
First of all Uninstall the application from your device .
go to Project > Clean. then you can run your project again
it will be remove your error strong text
I closed the main.xml Layout file in Eclipse, and all of the sudden, this is what I get:
No XML content. Please add a root view or layout to your document
All of the xml code is gone, the Graphic Layout editor is gone, and I can't get anything back. I lost the whole project. I'm in Eclipse 3.7.
I really need help with this. It has done this to EVERY Android project I've ever created. I can't finish an app. I get 2 activities done, then Eclipse bones me with this screen again.
may be the xml dont save, you can try this:
right click the xml file -> compare with - > local history
in the local history to find right content
I thought ADT should come with a visual editor for building GUI : Easy way to build Android UI?
However, I just cannot find it. I was wondering where is the Visual Editor for Eclipse with the ADT plugin.
I can run HelloWorld application without problem. However, whenever I click on main.xml at the left navigation tree layout folder, here is what I get. What I wish to get is a WYSIWYG editor.
Select your main.xml file. At the bottom of eclipse you can see a Layout tab, click on it and eclipse will open the android gui editor.
As Paul Kearny previously noted, to resolve issue with seeing "Design" tab instead of "Graphical Layout" follow these 2 steps:
1) Delete project from the left of the screen, without deleting the source files
2) File -> Import -> Existing Projects into Workspace, browse and select your workspace folder and open your project
Graphical Layout problem fixed!
If you want to edit the layout visually, rather than through XML, click on the Layout tab at the bottom left of the main.xml window (in your screenshot, just above Problems).
Also note, there are issues with displaying some of the widgets. For example, the ListView does not render. So, my hint is to change ListView to just a View, then work out the details of the layout so you can get the colors, relative-ness, etc. Then switch it back to ListView. There is one other widget that I cannot recall off the top of my head ...
To resolve issue with seeing "Design" tab instead of "Layout" or "Graphic Layout", I had to:
1. Delete the project from Eclipse without deleting the source
2. Shut down and restart Eclipse
3. Import the project back in
You could probably skip step 2, but I did it just to make sure.
Hope this helps anyone else who has the same issue.
If your view is showing Design|Source for the .xml file right click on the main.xml and select open with - android common XML editor. Simple.
If it is happening to one particular xml, you can delete the file (make sure you copy the content first), create new xml and paste the content again.
I recommend that any serious Android developer stay far, far away from Eclipse/ADT Design View. This is a time-wasting tool that sorely lacks the attention it would need from Google to make it worth serious consideration. It doesn't render the views as a real device would. There is no way to bind dynamic data. Does it work with fragments (I think not)? For it to work properly and have useful features would weigh down Eclipse further and make it unacceptably slow. In my very humble opinion, the entire strategy for ADT's ui-design tools has failed.
Thus, the recommendation is: edit Android XML layout files by hand and use the only reliable testing mechanism you have for layouts: actual devices. You can always fallback on the emulator - but the emulator performs 50x - 100x slower than an actual device. I'm not exaggerating. Pick your poison!
new fix, took me forever to get this fixed, really simple....delete the xml file and undo the deletion (ctrl+z), double click and there you go. Hope this helps someone as it did me. No shut down required.
If you see "Design" tab instead of "Graphical layout", just close the project and open it again.
