Using decimal values for pixel sizes in Android?

Question

In android values xml folder, creating values with decimal values is meaningful or not?

<dimen name="list_margin_left">7.25dp</dimen>
<dimen name="width">40.3dp</dimen>  

Answer 1

Yes it is :

• in MDPI, 1 dp = 1 pixel
• in XHDPI, 1 dp = 2 pixels

So using 7.5 dp is the only way to get something 15 pixels large in XHDPI.
