Hello Friends,
Welcome you all in the Android Development Tutorial.
In this post we are going to learn “How to create a
horizontal marquee banner with the help of Graphical Layout”.
There are two ways of creating User Interface for an
Android Application.
1)
Code
2)
Drag and Drop
Suppose
I want to put a TextView widget in my Android Application, How do I do? First
way is I write a code for creating a TextView. Another way is, use the widgets provide
by ADT for creating a User Interface.
So today
we will create a horizontal marquee without any coding. I mean with the help of
Graphical Layout. Just change the properties of the widgets, according to that
code will also get reflected automatically.
Steps
to follow:-
1)
Create a new
Android Application
Create a new Android Project.
Go to File à New à Android Application Project
Change the Application name to “Horizontal
Marquee”.
Select all the default options.
Click Next
Click Next
Click Next
Click Next
Finish
Now you will have a HorizontalMarquee
application on the Screen.
The Graphical View you are seeing, that is
called as a Graphical Layout of the activity_main.xml
You are also seeing a default TextView (Hello
World) in the middle of the GraphicalLayout.
We will modify this TextView properties to
demonstrate Horizontal Marquee.
Zoom the Graphical Layout by the help of
zoom in icon.
2)
Modify the
TextView Properties
Click on the default TextView (“Hello
World”).
On the right hand side you will be seeing
a window names as Properties.
Whatever widget you will select it will
represent the Properties of that Widget.
From here we will modify the following TextView
Properties.
Change the default string:-
Go
to the Text ID in TextView, click on the small right hand side button.
Click
on the New String button.
When you click you will
see the following window.
Change the String Value,
please give any long text here.
Change the New R.string
to marqueeString
Click Ok
Click Ok
Your default text has been changed.
Change the Ellipsize :-
Go
to Ellipsize ID in TextView.
Click
on the right hand side small button.
Select
the marquee.
Change the Marquee Repeat Limit :-
Go
to Marquee Repeat Limit ID in TextView.
Click
on the right hand side small button.
Select
marquee_forever.
Change the Focusable and Focusable In
Touch Mode:-
Go
to Focusable ID in View.
Click
on the checkbox, make it TRUE.
Also
change the Focusable In Touch Mode to TRUE.
Change the Single Line:-
Go
to the Deprecated section, select the Single Line ID and make it True by
clicking on the CheckBox.
Modifications have been done. Have a look
of the activity_main.xml file. Whatever properties we have modified, code
related to that has been automatically added in activity_main.xml
3)
Run the
application
Save
all the changes. Do clean and Build.
Run

Your
application will come up with the Horizontal Marquee floating in the middle of
the Screen.
