TweetDeck Part 2: Preparing The Main View

Creating the Project
We shall start with creating the project. In Flash Builder go to  File > New > Flex Mobile Project and name it "TweetDeck" > Finish. For the template select the second one : View-Based Application. Flash Builder will create a new View named "TweetDeckHomeView.mxml" which will be the first one in our Project. Its in this View that the work will be done.
Placing the elements
Before we see every bit of the interface in detail, we will make a "skeleton" of our View. Here is the main Interface of the TweetDeck application on Android Evidently,the application is composed of 3 main parts , vertically.Here we are not using the standard "ViewNavigator" hence we are not using the ActionBar.For deleting the actionBar, we use the propriety "actionBarVisible" of the View object which we are going to change to "false".Here is the skeleton of the app with rectangles of colors : 

<?xml version="1.0" encoding="utf-8"?>
<s:View xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark"
        actionBarVisible="false">
  <s:layout>
    <s:VerticalLayout gap="0" />
  </s:layout>
  <s:Rect width="100%" height="40">
    <s:fill>
      <s:SolidColor color="0xFF0000" />
    </s:fill>
  </s:Rect>
  <s:Rect width="100%" height="100%">
    <s:fill>
      <s:SolidColor color="0xFF0FF0" />
    </s:fill>
  </s:Rect>
  <s:Rect width="100%" height="80">
    <s:fill>
      <s:SolidColor color="0xFFFF00" />
    </s:fill>
  </s:Rect>
</s:View>

After testing in the emulator , here is the result :
