In this we do we'll take a look on what is the you group's view.
Group is also a kind of view.
They are also displayed as rectangles on the screen.
If we click here on this tab on Image view you will see that image view is displayed as a rectangle
a.
You see the name constraint layout.
This is one of the verities of view groups.
If we click on it then you see that there is an external rectangle displayed on the display.
This is these view group constraint layout.
They are almost the same as simple views.
They have the same properties but view groups can display several elements in themselves.
For example as here image you.
That is they can contain one or more view takes you an image you or several text use.
They can be combined in different ways.
Well let's try to put text to here
and as you see it appears here.
These text you.
And now in our constrained cloud if we collapse it you see all these views.
Image you and sex you are inside the constraint.
If we go to the text tab we can see it more clearly.
As you see image you and text you are inside.
Example element constraint cloud because here is the opening constraint cloud tag.
This is it.
And below is constrained allowed in tack.
And inside this review group are two types of view Image view and text do you.
That is a view group can be considered as a container for other types of view.
If the view contains other views then it is called Parent view and the views which are incited to you
are the child views.
If there are a few view in view groups they are named siblings relatively to each other that is descendant
of the same parent.
For example here in our example constraint allowed is a parent for internal image view and TextView
and respectively image you is a child of constraint child and takes you is a child of constraint layout
to and Image view and text you.
In our example relatively to each other ah sibling views.
That is they are descendants of the same parent.
They are constrained about view group different view groups in their own way position their child views
constraints.
Layout is a relatively new view group it has appeared recently before it there were two main types of
view group.
Their Linear Layout and the relative layout.
Let's consider them.
