Different value folders in android

Question

I create different values folders in my application (values, values-ldpi, values-mdpi, values-hdpi, values-xhdpi, values-nodpi, values-w360dp-mdpi) . But some devices that belong to the same category. But with different screen sizes. But I see the font size in accordance with the density of the device in this answer provided by @PankajSharma, it is proposed to create folders like -

 res/values/dimens.xml res/values-small/dimens.xml res/values-normal/dimens.xml res/values-xlarge/dimens.xml 

I want to know what is the difference between me and different? I think the answer provided by @PankajSharma is simple. I also want to know which way is better?

Answer 1

The approach you are using is a valid approach, but a bit outdated. From HoneyComb there is a new way to fix it all. Your resource folder should look like this:

Please refer to the link I posted and familiarize yourself with the Smallest Width concept.

Hope this helps :)

EDIT: dimens.xml added to this post, try setting some standardization in dimens.xml , something like this:

This simplifies code maintenance and also reduces the number of dimen folders. Usually, instead of values-hdpi , values-xhdpi , etc., Files such as values-sw480dp-xhdpi may have more values ​​to configure, but then all this is contextual.

Answer 2

Create a single layout for the default 4.7-inch (hdpi) screens in the layout folder and in the size folder. This is your Superset .

Now let's say you need your layouts for 7-inch devices. Create values ​​folder-sw600dp for 7inch in portrait orientation

Now let's say that you want your layouts for 10-inch devices to create -dw720dp folder values

NOTE. - For landscape, just add "-land" before the folder names.

Now let's say that you have new devices, such as Xperia SP (4.7 'and XHDPI) and Nexus 5 (5 "and XXHDPI).

To do this, you can create values-xhdpi and values-xxhdpi-folders and similar add -land for landscape orientation.

I hope you understand how to create folders.

Now your superset is defined in the values ​​folder. Most measurements will only be used here. Now run the application on other devices. No matter what the mismatch is, just add this specific size to your values ​​folder

To check which folder your layouts, images are used from, use my trick.

Create five identical lines and put in it all the values, such as: Default screen Screen 4.7 XHDPI screen MDPI screen

Create five drop-down folders, most of them already exist: - drawable-hdpi, drawable-mdpi, drawable-xhdpi, drawable-xxhdpi, drawable-xxxhdpi Place the screenshots below in their corresponding folder under the same name

Here's what my res folder looks like, and I support all devices from screen 4.7 and above: -
