visibility-control display and hide settings

In Android development, most controls have the visibility attribute, which has a property of 3

Visible: Viewable

Invisible: not visible, but will occupy the original position

Gone: Not visible, will not occupy the original position

Viewable (visible)

XML file:

android:visibility= "Visible"

Java code:

View.setvisibility (view.visible);

Not visible (invisible)

XML file:

android:visibility= "Invisible"

Java code:

View.setvisibility (view.invisible);

Hidden (GONE)

XML file:

Android:visibility= "Gone"

Java code:

View.setvisibility (View.gone);

How do I determine the display state of a control in code?

Getvisibility ();

And then with
View.visible
View.invisible
View.gone
