屏幕适配 AndroidAutoSize 完全解析，踩坑测试 与 使用注意事项总结
1、设备屏幕参数获取、计算、几个设备相关参数
计算示范：某手机 6.39英寸 （对角线），1英寸是160dp，所以是 1022.4dp，分辨率 2340 x 1080，勾股定理得到对角线长为2577.2 ，所以屏幕密度比是2577.2 / 6.39 = 2.52。

以上数据表明：
1、设备密度比不完全是真实的屏幕密度比，各机型都有出入。平板设备与真实屏幕密度差异比手机大得多，所以pad自带放大效果。
2、横竖屏获取的宽高相反，另外由于导航栏的差异 导致获取的高并不准确。
3、xdpi 和 ydpi是真实的屏幕密度比，两者相同代表屏幕两个维度上密度均匀
ps:可以利用此 界定 超过7.5英寸的设备 是平板：
2、AndroidAutoSize概述
目标适配效果：以宽或者高一个维度去保持 某长度 在设计图上的占比与 实际显示在设备上的占比 一致。
具体描述：宽维度为例：设计图宽是360dp，那么一个控件设计图上宽100dp，那么无论在任何手机屏幕上该控件都占屏幕的100/360，所以 本质就是 以屏幕宽度 / 设计图宽 作为新的px dp 转换关系 ，替换系统dp px原有转换关系。
如何变更系统的屏幕密度比：系统dp转换的场景，如XML，基本都是通过 DisplayMetrics 来计算的 ：
例如：xml加载 走到 ViewGroup generateLayoutParams
几个变量：
DisplayMetrics#density 就是上述的density
DisplayMetrics#densityDpi 就是上述的dpi
DisplayMetrics#scaledDensity 字体的缩放因子，正常情况下和density相等，但是调节系统字体大小后会改变这个值
所以只要变更这几个变量值就可以实现适配目标。
一般理解：
每个activity可以获取 DisplayMetrics 、Configuration activity.getResources().getDisplayMetrics ( ) activity.getResources().getConfiguration()
Application可以获取 DisplayMetrics 、Configuration Application().getResources().getDisplayMetrics ( ) getApplication().getResources().getConfiguration()
Configuration里的 screenWidthDp screenHeightDp也被系统使用，需要同步修改
对于字体sp则同步缩放，比如字体设置不是标准，大字体放大了2倍，autoSize对于dp缩放倍数是1.5则 字体最后 相对于原有dp放大 了 两者的乘积3倍。
只能以一边维度进行适配，另外一边则按次维度 缩放 遵照常规布局规则。
3、AndroidAutoSize 核心逻辑代码：
注册provide提前初始化
初始化 重点 ui设计值 、宽高维度基准、记存原始屏幕参数
设置activity生命周期回调
回调监听里面用WrapperAutoAdaptStrategy代理默认的DefaultAutoAdaptStrategy适配策略适配，可以看到适配前后的时机都对外进行了暴露，此处回调可以做一些自定义操作
默认适配规则处理了 外部三方库的适配兼容、CancelAdapt 取消适配、CustomAdapt自定义适配
CustomAdapt将使用中自定义的设计图尺寸就行适配
在onCreate、onStart里面执行了适配，并且支持了对 Fragment的适配支持
Fragment在onCreate执行了一次适配
开始适配
跟进适配维度与UI设计图值执行最终的autoConvertDensity方法
核心计算
targetDensity 即前面所说的 以屏幕宽度 / 设计图宽 作为新的dp px转换关系，重新计算Density Dpi ScaledDensity等值后 修正activity、application的DisplayMetrics与Configuration
至此，AndroidAutoSize 适配结束。
简而言之，AndroidAuSize利用对生命周期监听修改DisplayMetrics的参数进行页面缩放，实现横或竖一个维度上 某长度值在 任一手机屏幕上显示效果与 在设计图上 占比相等。
值得注意的是，初始化中增加了
1、对字体大小设置变更的监听处理
2、横竖屏切换会导致宽高互换，即AndroidAutoSize 设计原意是 横屏状态下的页面 也要参照横屏的设计图 ,默认用宽维度来进行适配
4、是否靠谱？测试验证
验证displayMetrics参数的修改；验证横竖屏切换生命周期 ；验证XML、动态加载两种 ；
测试机器 vivo X27，View 100dp x 100dp ,xml静态添加绿色的View，onResume之后post 执行 动态添加红色的View
XMLLandScapeActivity是清单文件指定横屏的activity，CodeLandScapeActivity是在onCreate之后动态设置横屏的activity，手机开启屏幕旋转。

更复杂的旋转来回进出将会出现更多的缩放变动。
综上测试：
动态横竖屏的切换、不同横竖屏页面之间的来回跳转、View静动态加载方式 等都会使AndroidAutoSize的缩放倍数发生变化。
5、调整优化
1、横屏的页面是否也可以按照竖屏的放大比率适配？
如果可行 那么直接去掉AndroidAutoSize 库中application.registerComponentCallbacks onConfigurationChanged 中对于mScreenWidth和mScreenHeight的修改即可去除某些情况下缩放变化问题
或者 AutoSizeConfig.getInstance().setOnAdaptListener 在onAdaptBefore时重置 AutoSizeConfig.getInstance().setScreenWidth(screenMin); AutoSizeConfig.getInstance().setScreenHeight(screenMax);
2、onConfigurationChange会重置displayMetrics导致动态添加的View缩放不一致
所以 onConfigurationChange监听里面也追加一次参数修改 可以保证动态添加的View缩放比一致.代码如下：
AutoSizeConfig.getInstance().setScreenWidth(screenMin);
AutoSizeConfig.getInstance().setScreenHeight(screenMax);
AutoSize.autoConvertDensityOfGlobal(this)
以上两处调整后，缩放比稳定，测试验证有效。
1修改通过无论横竖屏始终使用 手机短边长度/设计图短边长度 来确保缩放比率的一致 就要求不能完全照搬设计图各控件的宽。比如设计图是16:9比例 短边1080 x 1920px 算 360dp x 640dp 如果某个ui控件铺满则宽度填640dp，那么在1080 x 2200的手机上就留白，在1080 x 1800 手机上将越界。 另一方面设备的长宽比差异，导航栏差异、设备获取差异导致 没有办法按长边计算适配，为了修复上述问题，使用1方案在宽维度上不能照搬设计图宽，还是需要搭配使用 matchParent 、wrap_content、gravity
因为AndroidAutoSize 改变了dp px转换工具，所以app的dp px转换工具类也需要做相应修改。
6、思考与讨论
1、正是因为activity共用displayMetrics，所以cancelAdapt需要还原初始参数。
2、关于 CustomAdapt和Fragment的使用冲突
setCustomFragment(true)，会导致在fragment onCreate里面再次设置缩放比，如果fragment与activity适配规则不一致则activity的会被后加载的fragment 再次适配覆盖。
所以使用fragment的需要重点关注。有人说我没用fragment貌似也有问题。则是三方库设置监听创建的fragment导致，比如glide的SupportRequestManagerFragment会覆盖你的activity缩放参数，此处示例感兴趣的可以自行测试。
3、在手机、平板上完全按照等比缩放设计图的方式去显示是否符合自家 UI的设计要求？
4、因为有测试中的bug，如果只按照短边适配，那么横屏下的ui控件和竖屏状态下的宽高是一致的，UI是否接受，可以横屏也可以竖屏的这种动态页面写ui有什么注意点?
5、如若完全使用AndroidAutoSize机制，完全不用matchParent 和wrapContent，所有的页面控件宽高都照搬设计稿尺寸，后续一旦去除的成本会很高，并且将完全不可以对缩放比作修改。
6、平板尺寸大，设备屏幕密度与真实的相差也比较大。所以在平板上的页面完全按照手机上等比缩放会显得特别大。
例如 如下代码通过 修改设计图尺寸 限制 缩放比率 ，可以使的控件在平板上略微放大，但同样引入问题3，如果一个页面完全照搬设计图写的宽高dp值，那么限制缩放比率可能将使得控件显示区域不能铺满 屏幕上将留白
6、如果想使用AndroidAutoSize的缩放机制 而又 不完全被 限制死 那么 在布局的编写上有没有什么操作空间 以及注意的地方
UI需求的统一才能开发的统一，选择了一个方案可能得接受随之而来的缺点，在 UI需求与开发方案的一致的基础上找到平衡点 才能选择适合自己的屏幕适配方案。
