I added LinerLayout weight sum of it is 1 and I added six imageView in it so I want to change the layout_weight of imageVeiw when image1 visible layout weight = 1 and when image2 visible layout_weight of image1 = 0 and layout_weight of image2 = 1 — Hussain Adel Alwaely, Aug 25 '20 at 20:32

Use This:

var params = LinearLayout.LayoutParams(
    LayoutParams.MATCH_PARENT,
    LayoutParams.MATCH_PARENT,
    1.0f
)
imageView1.setLayoutParams(params)

in this line: var param = LinearLayout.LayoutParams( We are using LinearLayout because your image view is inside a LinearLayout

When I did it he convert the code to `var params = LinearLayout.LayoutParams( LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT, 1.0f ) imageView1.layoutParams { params }` and the last code send me wrong in word `layoutParams `of `imageView1.layoutParams { params }` the message is Expression 'layoutParams' of type 'ViewGroup.LayoutParams!' cannot be invoked as a function. The function 'invoke()' is not found – Hussain Adel Alwaely Aug 26 '20 at 15:00
Use = params not. {params} – Tal Mantelmakher Aug 26 '20 at 15:29
I know it dear , but the problem is I must us `imageview1.setLayoutParams(params)` it works with `setLayout....` thanks a lot dear – Hussain Adel Alwaely Aug 26 '20 at 19:23
