android:layout_marginRight="@{rankingItemViewModel.marginLeftOrRight ? 0: 100}"

Anyone can teach me what is wrong??….

[gildor]

What is your problem exactly?

[gildor]

Probably different types

[gildor]

or marginLeftOrRight is not availabler

[changhyun]

marginLeftOrRight is one of member of view model

[changhyun]

compile fail…

[gildor]

and what is compile error?

[julioyg]

missing the units?

[gildor]

maybe should be
rankingItemViewModel.marginLeftOrRight == null ? 0 : 100

[gildor]

or what is you check suppose to do

[changhyun]

cannot find the setter for attribute ‘android:layout_marginRight’ with parameter type int on android.widget.ImageView

[changhyun]

same error when i use code you wrote

[gildor]

try to use dimensions instead

[gildor]

100 -> 100dp

[changhyun]

cant do that

[changhyun]

I tried that but xml says no lol…

[gildor]

use @dimen/some_dimension

[changhyun]

also I tried that…

[changhyun]

xml says good, but occur same error code

[changhyun]

I am so confused

android:layout_gravity="@{rankingItemViewModel.marginLeftOrRight ? Gravity.RIGHT : Gravity.LEFT, default = right}

android:visibility="@{rankingItemViewModel.detailVisivility ? View.VISIBLE : View.GONE, default = gone}"

[changhyun]

first one is not working but, second one is working

[gildor]

I would just use custom binding adapter

[changhyun]

hum… anyways Thanks !!

Also, if first one doesn’t work, why not just use default = Gravity.RIGHT instead
