Android: Pixel perfect user interfaces for Android applications

Posted by Unknown Rabu, 28 September 2011 0 komentar

We all know that User Interface is an extremely important part for every application that pretends to be attractive and popular among users. This is the axiom. Android mobile system is very popular and is installed on a big variety of devices: from low-tier cell phones (like HTC Hero) with small low density screens to high-tier phones (like Motorola Atrix, Samsung Galaxy S, etc.) and tablets with big high density screens. Moreover there are a lot of Android devices vendors - Samsung, HTC, Motorola, LG, Dell, etc. As a result we have so called "fragmentation" problem.

Today I want to reveal one useful feature of ADT (Android Development Tools) plug-in for Eclipse. Do you think that it will be DDMS perspective? No, man! :) I think any Android developer (from novice to expert) should know and use DDMS perspective which is so useful and powerful.

But there is also one more nice ADT feature that will help us to create better User Interfaces!

This is a "Pixel Perfect" perspective. It can be accessed from the menu:

Windows - Open Perspective - Other - Pixel Perfect

The main goal of "Pixel Perfect" perspective is to provide easy way to review user interface of our application in details. There are several useful features:

image of the screen that is currently visible on the emulator or device and
magnified image of that screen.You can move the cross-hair to inspect every detail (including color values) of your screen to make pixel perfect user interface! :)

"Pixel Perfect Tree" - to inspect visual objects hierarchy

"Load image overlay over the screen" - it's very useful for matching actual screen with the desired screen from a specification.

As you may see "Pixel Perfect" goal is similar with the Hierarchy Viewer tool (which is free standalone tool, available at android-sdk\tools\). Hierarchy Viewer tool has not only all features of the "Pixel Perfect" perspective, but also a lot of unique features: extended Tree Hierarchy view, visual indicators for measure/layout/draw performance, etc. But if you prefer doing all the stuff using IDE and you need just pixels and colors matching, then the "Pixel Perfect" ADT perspective is a good choice.

I want to believe that one day most of Android apps will be designed so well that even iOS users (who are so proud of iOS design) will be envious! ;-)
