Questions tagged [layoutparams]

The LayoutParams is a helper class that stores various layout information related to the Android view for which it is used.

The LayoutParams class is generally implemented as a nested class(in the ViewGroup that will use it) and it is present in all of the platform's default subclasses of ViewGroup. The class stores information like the widget size but can also store other details like the gravity of the view or the coordinates on the screen. Each of this value will be used by the parent to determine how to show that child View on the screen.

The LayoutParams is an important class and the user should take care and always use the appropriate LayoutParams for each View. The general rule of setting a LayoutParams for a View is to use the type of LayoutParams declared by its parent.
