Is it normal, that styles and includes don't have any effect in preview in Eclipse? The more I get into Layout building the less I can use the preview. Even in the newest SDK Version it's so poorly made.
Yes, this has been my experience with the Eclipse layout preview.
The layout preview of Eclipse is not suitable for a real representation of the final layout.
To get a real representation use either an emulator or a real device and the HierarchyViewer if you want to debug your layout.
There exists DriodDraw which is a web-based visual Android layout composition tool written in Java. It is however limited in its functionality and maybe not really what you were looking for.

I have been facing this issue while creating any android program/app using android studio. Whatever I design in android studio, it is not displaying properly as designed in android studio while running the app on my phone.
In short, sometimes size and the places of the controls get changed while running the app on my android phone. Please help. Thank you.
That's probably because of the difference in screen sizes of your preview and your physical phone . I've recently started using constraint layout and I think it's the best so far, a bit confusing at first but easy to understand it, it even has an option for percentage of width/height of the total screen for a view. Try that out.
I am using the visual editor in Android Studio. In there, the text is really big, like how I want it to be. But when I build it on a physical device it is default size.
Thanks in advance!
simply create many layout that support pixels make all your layout handle your show way
read this to understand the idea
https://developer.android.com/training/multiscreen/screensizes
and do this in your code then check the devices

there's also something else you may have not noticed yet
in android studio Preview Layout you can choose your the preview device as your actual device or same as it.
this way the preview design will be same as your device. but for other devices you should have above answers in mind.
I've seen some Layout Editors in Android Studio with a ruler on top and on the side for the Preview window and I'm trying to figure it out how to enable, any ideas? I'm using Android Studio 3.0.1 and I can't see them.
Seems like the ruler has been removed from the Preview tab of the Layout Inspector since Android Studio 3.0. It's 2020 now and Android Studio 4.0 has a new Layout Validation tool to preview the layout on different devices and display configurations. Not really the same but at least the Layout Inspector seems much more reliable than those days.

The Guidelines are the rulers. You move them around to get the measurements you need. Expressed in percentages or units.
Android layouts are very tricky to get right. Especially for an inexperienced layouter like me. At the moment I use the following workflow:
Design the layout in IntelliJ, using IntelliJ's GUI preview window
Test the layout on my device
Test the layout on different emulator images
This approach has several problems:
The IntelliJ is very inaccurate (often the layout looks very different on the device)
Testing on my device is good, but here I have only one fixed resolution and PPI
The emulator takes AGES to start up. If using multiple emulators things get worse
That's why I'm looking for an alternate solution: a tool, that quickly renders Android layouts (no app logic required). This tool should support different resolution and PPI settings and should be as close to the actual looks on real devices as possible.
Is there such a tool?
What other alternatives are there?
I know this is not a technical related question.But i do not have any idea.I am going to develop a project which should be supported in both phone and tablet.Is it possible having one project working for both tablet and phone ?
Yes. The only thing you need to keep in mind where you keep your graphics. Because it will cause different problems if you do not treat and handle them depending on the screen size. Only thing matters is the android version. If you deploy your app in any phone or a tablet where the version is newer or equal to the target version it works. But of course you cant take a call or some other mobile functionality from a tablet if its not supporting that features.
You can use drawable-hdpi,drawable-mdpi and drawable-ldpi for the graphics(images which use in project) and also use layout with multiple screen by custom layout like layout-480x320 , layout-600x1024 etc. in layout you can custom screen xml file.
