A ViewGroup is a special view that can contain other views called children. The view group is the base class for layouts and views containers. For example, if there are three text fields and two of them declare a weight of 1, while the other is given no weight, the third text field without weight will not grow and will only occupy the area required by its content.

The other two will expand equally to fill the space remaining after all three fields are measured. If the third field is then given a weight of 2 instead of 0 , then it is now declared more important than both the others, so it gets half the total remaining space, while the first two share the rest equally.
