Actually i want to design my app through css and html and want to code that css generated elements throgh android code.
Like suppose i have created a button in css.Can i use my android native language to code that button?
Officialy, java is the development language for android. So, if we are being really strict, you should use whatever tools java and the android sdk give you to create and style your elements (you can read about it here). But of course, there's always more than one way of doing stuff, and thanks to the Adobe overlords, you might just have what you are asking for.
Phonegap is a highly powerful opensource framework that allows you to code you entire app using HTML, CSS and JavaScript. Once you are done coding, phonegap does its magic and generates the app for you, so you don't need to touch a single line of java code.
So, basically, I don't think there's a way of using CSS in pure native android code (if there is, please feel free to share). But if you really want to use it, Phonegap is the way to go (I've used it before, it's cool)

I have made a website using HTML5.
However, I'm trying to make the app using the CSS, JavaScript and HTML I used for the website. Is that somehow possible?
I must use Android Studio.
Nope, you can't do that.
Android Studio is based on Java (logic) and XML (design).
XML and CSS are a little bit similar. You have paddings and margins too.
However. Prepare yourself to put work into the project.
But why do you need an app when you can also show the same contents in a website that works on way more devices? You can also use a WebView to show your website in the app.
If it must be native and you can't use a WebView, just rebuilt the design, Check out the material design guidelines, stick to them and your app will be easy to use for the users and look awesome.

I want to develop application in android and iOS both.
But i am confuse between native development and development using react and node.js etc.
Please help me to choose (If possible specify reason).
P.S Here cost is not an issue.
If you need high performance and attractive UI and don't want to be blocked by some functionalities that may not br provided by cross platform, I recommend you to use native platform. But if your app doesn't need to be very attractive and doesn't need too much processing, then you can use cross-platform. Actually for many features you need to add plugins if you are building cross platform app and adding number of plugins makes your application slower.
OK, well there isn't much data to go on, but there are several options if you want to write cross platform apps.
There is:
Sencha Touch - HTML and JavaScript
PhoneGap - HTML, JavaScript and CSS
QT - C++ and QML
Appmethod - C++ and Object Pascal
Xamarin - C#
Visual Studio - looks like you can do C# or C++, or Unity for games.
and probably a lot more...
Why would you choose one of these instead of writing in the native language for the platform?
Well, the pros seem to outweigh the cons. If you are targeting several platforms, I would choose one of the options above, simply because you only have to write everything once. If you did it native for each platform, you would write everything twice or maybe three or even four times. Using one of the above tools will be much easier and save you time, and they might be just as seamless and workable as native development.
To simply answer your question, If you would like to be able to write your app once, and be able to manage all future updates by managing only one code base, do cross platform using one of the above tools. The only downside is that you might have to learn a new language (but with a place like Stack Overflow, learning new languages is pretty awesome). It will save you time in the long run.
I have some issues in working with Android layouts and make them adapt for all screen sizes..
I have found that there is an alternative solution : Android Bootstrap http://www.androidbootstrap.com/ for that and provide nice UI components (buttons etc...).
Since I'm developing natively, is this kind of frameworks won't make the App runs slower ?
Is this only a UI framework like for the web (Bootstrap from twitter) ? if not, can we use with it everything in Android (Camera, micro etc...) and Can we include some Jars like Zbar ?
Thank you.
I have found that there is an alternative solution : Android Bootstrap
It is not an "alternative solution". You still will need to be "working with Android layouts and make them adapt for all screen sizes", because Android Bootstrap does not change much related to that.
and provide nice UI components (buttons etc...)
It uses the same Android widget set that all other Android apps use.
is this kind of frameworks won't make the App runs slower ?
There is nothing in an Android Bootstrap project that would necessarily make the app significantly slower.
Is this only a UI framework like for the web (Bootstrap from twitter) ?
It is not even that. It is a starter project that demonstrates how to tie together a dozen or so open source libraries for Android app development. You can think of it as an extended version of the templates used to create new applications and activities in Eclipse or Android Studio.
This is not to say that Android Bootstrap is bad -- far from it. However, it does not resemble your description.
can we use with it everything in Android (Camera, micro etc...)
I have no idea what "micro" is with respect to Android. Since you are writing an Android application, just like any other Android application, you can use it with whatever parts of Android you choose to.
Can we include some Jars like Zbar ?
I see no reason why not.
It is very common for such templating engines not to have exactly most components you need. for android it is basicallly about adding support third party libraries to get the exact experience you need.
Thus you may want to consider adding more or lacking parts by leveraging some external libraries like those from HERE
I want to use a html file in android for generate a layout from html.... any one knows the any framework available in for android
There're several reasons why you need that and what you can do.
If you are very familiar with HTML and want to build an Android App, you can use Android WebView which can use the Chrome engine internally.
If you're looking for a way to write portable code and have it deployed to Android and others like iPhone etc., then take a look at the tools you'll find like mobilehtml5 or appshed. With the html5 standard, most of these portability tools are based on this.
Finally. I must say, that I'm not aware of any tool that actually generates xml and java from html.
I am rewriting an Android project, and I am stucked and sucked at making the GUI look like the way I wanted it too. It is easily achievable using HTML and CSS, I have done it with PhoneGap, CSS, HTML, JS, but it is kind of slow, so I want to do it native using Java.
(My background is C++ and some web programming stuff)
What I have been encountered so far is that the default GUI builder is not really pretty and I feel frustated almost every the time using it. And people recommend droiddraw in few other questions in Stackoverflow, but it also not resulting in pretty GUI as well.
What I want to have is some flexibility like HTML and CSS and from that I can execute native code.
I believe I can achieve GUIs like from the Facebook or Twitter client easily with HTML and CSS, but if i m going to do native using the SDK, I think I'm gonna need something like 1 month just to do the GUI.
So the questions would be:
Is there any GUI framework for Android SDK ? (More high level then the provided one)
How to render HTML/CSS that allows executing native code on interaction with its element.
Any suggestions welcome for any workflow.
And of course, Open Source solutions are preferable.
There are some projects for some iphone like widgets in android. You can find them seperately mostly in github, so I have not even seen a complete higher level widget library yet. But you can give appcelerator a try. You are writing html,css,js and it compiles to native code. I personally did not used it. It is a free software. Some people are happy with it, and some are not. You should read some experiences before beginning development. http://www.appcelerator.com/
