I am a little bit desperate because I'm trying to know how can I know the exact list of different dimens.xml(hYYYdp) I have to create in order to support all the screen sizes. I think I have already seen all the related questions to mine but none of them has helped me to solve this doubt. This is the most related question that hasn't solved my doubt: How to define dimens.xml for every different screen size in android? .
To give you some context. The reason of having different values according to the screen size is because I have a ConstraintLayout with some items that have Top and Bottom margin and in some devices that margin is not looking good. In this post I made, someone suggested me to use different margin values according to the screen size: How to solve TextView being cropped in small devices because of layout margin?
I have thought that as the margin is dependent of the height of the device (as I am using only Top and Bottom margin) I would have to create a list of different dimens.xml files according to the height of the device (hYYYdp).
The real concern I have is that I don't know how many dimens.xml files I have to create to support all the screen sizes. What I have been doing is creating some specific dimens.xml files that are working for specific devices, but I think there has to be a general list of all the dimens.xml files that have to be created to support all the screen sizes.
For example, what I have been doing is to look the test devices of Android Studio one by one and create specific dimens.xml files for them. This is the process I have followed to create a specific dimens file:
Example:
1- First I have seen the list of the test devices of Android Studio, for example let's take this one:
2- After this, I have calculated the dp of the height of this specific test device:
240x400px (ldpi) device. So the height's dp is = 400/(120(ldpi)/160)== 533.33dp
3- Finally, I have added the dimens.xml(hYYYdp) correspondent to this specific device with the specific margin value that is looking good:
I have repeated this process for most of the test devices of Android Studio but as a result, I have a list of specific devices but I think there will remain many devices without being supported as not all the Android devices are in the Android Studio test devices list. I hope you have understand what I am trying to explain.
