+# CommonSize [![](https://jitpack.io/v/licheedev/SmallestWidthDimens.svg)](https://jitpack.io/#licheedev/SmallestWidthDimens)
+
+Android SmallestWidth屏幕适配方案
+
+## 原理 smallestWidth
+
+https://developer.android.com/guide/practices/screens_support.html#NewQualifiers
+
+关键的地方就是sw后面数值的单位是`dp`
+
+* 跟hongyang的方案不同，不会用绝对分辨率适配，而使用sw（最小宽度）限定符方案
+* 只关注最小宽度，无视高度，不会受有/没有虚拟导航键影响，也可以适配18:9的全面屏
+* 设备的sw不会有太多，没有合适的配置的话，会使用最接近设备最小宽度的那个较小的配置（如没有小米mix2的392的话，会用384这个配置，误差不会很大）
+* 预览应该无压力，毕竟sw列表就是根据官方模拟器配置列表得来的
+
+```java
+// 获取最小宽度的代码
+Configuration config=getResources().getConfiguration();
+    int smallestScreenWidthDp=config.smallestScreenWidthDp;
+```
+
+## 使用
+
+1. 在根build.gradle中添加
+
+```
+allprojects {
+    repositories {
+        ...
+        maven { url 'https://jitpack.io' }
+    }
+}
+```
+
+2. 子module添加依赖
+
+```
+dependencies {
+        // 根据设计图的宽度选一个，没有就按照下面配置重新生成自己要的
+        // 公司美工喜欢做iphone(750*1334)的图，就选sw_750
+        implementation 'com.github.licheedev.SmallestWidthDimens:sw_750:1.0.0'
+        implementation 'com.github.licheedev.SmallestWidthDimens:sw_1080:1.0.0'
+}
+```
+
+没有合适的话，就按照下面配置重新生成一个module，复制到自己项目里面，然后 `compile project(':生成的模块名')`导入即可
+
+## 生成新的尺寸配置
+
+### 运行生成器
+
+![generator](https://raw.githubusercontent.com/licheedev/SmallestWidthDimens/master/pics/generator.png)
+
+### 生成器配置 generator_config.properties
+
+最小宽度列表 [smallest_width_list.txt](https://github.com/licheedev/SmallestWidthDimens/blob/master/smallest_width_list.txt)
+
+```properties
+# 设计图参考宽度数值，单位不限，可以填多个，分别以英文逗号,隔开
+design_width_list=750,1080
+# 最小宽度列表路径
+smallest_width_list=smallest_width_list.txt
+# dp资源范围
+dp_range=-360,1080
+# sp资源范围
+sp_range=1,100
+# 资源文件名
+file_name=sw_dimens.xml
+# sp资源命名规则,{x}为要替换的数值,负数会在前面加上"_"
+dp_res_reg=sw_{x}dp
+# sp资源命名规则,{x}为要替换的数值
+sp_res_reg=sw_{x}sp
+# 只删除目标module
+just_delete=false
+# 缩进空格长度
+intent_length=4
+```
