Interface Builder(User Interface Designer) for Android

I am working on Android since last 7 months....Also knowing brief about I-phone application.

In Android, There is a bad layout editor in Eclipse, but it's neither good nor User Friendly as I-phone Interface Builder is.

Is there any visual designer that would be on par with the iPhone "Interface Builder" ?

Ya, DroidDraw is there but not that much user friendly as Interface Builder of I-Phone...开发者_运维技巧

Googlelabs has launched App Inventor .

I havent tried it but it may be help to design interface and code easily.

What is Google App Inventor? 

As i have found one article,in which they have given one line definition as below:

App Inventor is a new tool in Google Labs that makes it easy for anyone—programmers and non-programmers, professionals and students—to create mobile applications for Android-powered devices.

I think you may be a little spoilt by Apple! The Android layout editor has its quirks, but once you've settled in it's actually very fast to iterate with and get the results you want. Remember Android and iOS are quite different beasts, and by nature of Android being designed to work on a large range of different devices and screens, it's layout editor is also very different.

Just dive into it, get comfortable using the layout editor and you'll be settled in no time.
