Difference between layout_width and android:width

[Hardik Trivedi]

Hi all,

You all must be familiar with android:layout_width and android:width attribute in layout's xml file.
I am very confused with this tow tags. Sat I have TextView then I can use both tags. But if I put only width tag android asks for layout_width tag. So I am very confuse regarding use of both tags.
Please explain...

I believe layout tags are mandatory tags havent used width and height seperately though.
