Android TecHub: differnt size

There is main issue in android to design your application in a way to application should look proper in all devices whether it will small size device or it will tablet, So Today I am going to Explain How to design your application For different size of devices.

Step - 1:
First Create New Sample application,

For Create New Application in Eclipse go to

File-> New-> Android Application Project

Now Press Next...Finish.

Step - 2:

Set "res" Folder,

Create new 4 folders in "Package Explorer -> YourApp -> res" folder,with name

values-small
values-normal,
values-large
values-xlarge

(Note : if you cant get find Package Explorer then go to in Menu bar
"Window -> Show View -> Package Explorer")

Now Create XML file in all this 4 new folders with same name "dimens.xm".

Step - 3 :
Set TextSize of Textview:

Now Let we set on size of font for different devices using by calling values from dimens.xml file.

Open Your main design xml page from Layout folder.and take one textview
and call text size from dimens.xml file as give in below.

Yes,It will give an error when we set "textsize" in textview because we trying to fetch value of textsize from dimen.xml but we are still not define value in dimens.xml,So let we define it in all dimens files.

Step - 4:
define TextSize in all dimens.xml:

now set values of textsize in dimens file,

For "values-small -> dimens.xml" use below code,
<dimen name="textsize">16dp</dimen>

For "values-normal -> dimens.xml" use below code,
<dimen name="textsize">20dp</dimen>

For "values-large -> dimens.xml" use below code,
<dimen name="textsize">35dp</dimen>

For "values-xlarge -> dimens.xml" use below code,
<dimen name="textsize">55dp</dimen>

Thats it!!!!
Now when you can check your output for all devices it will look appropriately for all devices .

By this way devices will fetch textsize from dimens.xml.
