I am using 4 textviews in a linear layout. I have assigned a weight of 3 to one textview and a weight of 1 to the remaining three textviews. I want to know how the screen real estate is calculated and allocated to each textview based on the assigned weight.

  • The sum of all weights is the total, and the individual weights are the fraction of that total, pretty straight forward really. – ci_ Jun 21 '15 at 11:17

  • I agree, but what happens when one of the views is assigned a weight of 0 but is still present on the screen? How does that fraction work out? – Mudit Kakkar Jun 21 '15 at 14:13
  • Layout_weight distributes _extra_ space among views, you cannot use it to hide a view. It's all in the link. – ci_ Jun 21 '15 at 14:26

you can assign the linear layout with

 android:weightSum="1"

and then this 1 represents 100% of the height/width (whatever you are using)

then in your textview if you use 

android:layout_weight="0.2"

then you're giving the textview 20% of the layout space, and so on.
