How to set aspect ratio in xml (dimens.xml in values folder) to set different aspect ratio depending on devices?

Maybe a stupid question but in android how can I set aspect ratio in xml (dimens.xml in values folder) to set different aspect ratio depending on devices

I tried :

layout.xml

app:layout_constraintDimensionRatio="@dimen/common_image_aspect_ratio"

values/dimens.xml

<dimen name="common_image_aspect_ratio">3:2</dimen>

but it doesn't seem to work.

Any help would be appreciated, thx :)

If you want to define a resource for in the form 3:2 you should use a String:

// values.xml
<string name="common_image_aspect_ratio">3:2</string>

// layout.xml
app:layout_constraintDimensionRatio="@string/common_image_aspect_ratio"

Using a String also applies when setting a ratio programatically:

 (view.layoutParams as ConstraintLayout.LayoutParams).dimensionRatio = "3:2"

Try to write 1.5 instead of 3:2. Generally, you should use decimal format, not fractional. Hope it will help.
