Android 自动适配屏幕方案—— smallestWidth

smallestWidth限定符适配原理和屏幕分辨率限定符适配一样，都是通过创建多个values文件夹，系统根据限定符去寻找对应的dimens.xml文件，以确定不同设备上的大小展示，smallestWidth 限定符适配是拿 dp 值来等比缩放.

如何使用

一、添加 ScreenMatch 插件

二、dimens文件添加

添加一份dimens.xml文件作为适配的基准，文件内容主要声明尺寸

<?xml version="1.0" encoding="UTF-8"?>
<resources>

    <!-- Your custom size defind by references, can be writted in anywhere, any module, any values/*.xml, for example: -->
    <dimen name="common_margin">@dimen/dp_15</dimen>

    <!-- dp and sp values, must be defind in this file! -->
    <!-- view size,you can add if there is no one -->

三、screenMatch生成values

四、更新配置

在使用了ScreenMatch时，在Module层级的目录下会有一个ScreenMatch配置文件------screenMatch.properties，在其中可以更新配置，如果要更新需要适配的尺寸，可以在如下的代码中进行变动

base_dp=360
# Also need to match the phone screen of [match_dp].
# If you have another dp values.
# System default values is 240,320,384,392,400,410,411,480,533,592,600,640,662,720,768,800,811,820,960,961,1024,1280,1365
match_dp=
# If you not wanna to match dp values above. Write some above values here, append value with "," .
# For example: 811,961,1365

base_dp 是你的基准尺寸，可以在System default values中添加你需要适配的尺寸，然后重新执行第三步重新生成values及对应的dimens.xml文件。
