Android automatically adapts to screen 2. Custom Size Method

This is a self-developed method. It may be a relatively stupid method. Therefore, not many people have proposed this method to solve the adaptive problem. Although this method has many disadvantages, it is sometimes a good method.
First look at the figure below

We can see that I have defined two sets of size files. We can see one of them.

This is the code in the dimens_height.xml file under the values-480x320 folder, I divide the entire height into 80 equal points, this is because most of the screen width or height is an integer multiple of 80 (except for some special ), different equi sets different size values in different resolutions.
Since each set of interfaces should be written into one set, some may feel bad, but it is relatively simple to write and does not need to be changed in the future, so sometimes you can also consider using it!
Let's look at the layout code of my Demo (dimen_layout.xml)

</LinearLayout>

The above is the unified layout code I wrote, let's take a look at the display effect on two simulators with different resolutions (note that custom dimensions are also used for values like margin in my code. If this margin is controlled using layout_weight, there is no doubt that more linear la s need to be nested, so none of them is perfect. These 2nd methods are sometimes easier to use)
