Eclipse - Android Layout Editor is the best result in my experience. If you perfectly study the various types of layouts and their attributes, you can create any flexible layout (flexible in the sense that it can be viewed from any screen resolution).
Yes, DroidDraw is useful for beginners , but let me be frank, I started linking with this design tool, but later I just started with my own layout editor for Android, and now I have enough practice, so I suggest you study Android layouts and their attributes. Focus on RelativeLayout first, because in most cases they are used in most applications.
And yes, I would also like to tell you that we have basically 2 design patterns:
- TabBar design template (according to my experience, do not do this in any way, because you may need to convert any iOS application to an Android application, so you need to have a tab design template in your Android application and you will need to control actions through an ActivityGroup and its not as easy as the DashBoard design template.
- DashBoard Design Template . (In my experience, you should go with this design pattern because most successful Android apps implement this design pattern, for example, evernote, facebook, stackanywhere, google docs and many others).
