How to programmatically set the width of a LinearLayout?

Question

Android

There is a slider source and a lesson at the link: www.oodlestechnologies.com/blogs/Facebook-Style-Sl...
In this case, the width of the "left_menu.xml" file is determined by the TextView (android:layout_width="260dp")
How do I set the width for "LinearLayout" of "left_menu.xml" file depending on device screen? For example, I want the width of the "LinearLayout" to always be 1/3 of the device's screen? Or any way to set TextView width to 1/3 of device screen width.

If you need to proportionally place the elements on the screen, then it is better and easier to not find weight.
