android - Using Constraint Layout to center two items together in the center -

here intended layout.

<-   actionbar  button  [ image1 ]            [image2][image3]       [image4] 

doese know how support constraintlayout? image2,image3 in center , little or no margin between them. image1, , image4 near left right edges respectively.

is there anyway achieve same linearlayout or relativelayout row of images?

does coordinatorlayout have root layout? , if support actionbar?

yes, possible (as long know images aren't wide overlap, , long image2 , image3 same width).

positioning image1 , image4 easy; can constrain outside edges outside edges of parent.

then use these constraints position image2's right-hand edge exact center of parent:

app:layout_constraintright_toleftof="parent" app:layout_constraintright_torightof="parent" 

and these constraints position image3's left-hand edge exact center:

app:layout_constraintleft_toleftof="parent" app:layout_constraintleft_torightof="parent" 

update

if know in advance image2 , image3 not same width, , need combination of two centered, (as far i'm aware) can solve problem introducing intermediate parent (e.g. linearlayout).

in case, you'd position image1 , image4 parent edges before, , use these constraints "center" linearlayout inside constraintlayout:

<linearlayout     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:orientation="horizontal"     app:layout_constraintleft_toleftof="parent"     app:layout_constraintright_torightof="parent"> 

then place image2 , image3 inside linearlayout.
