前言Android发展到现在，很多成熟的应用上已经集成了插件式换肤的功能，比如网易云音乐，手机QQ，QQ音乐等等。但是，成熟稳定易用的开源换肤框架并没有出现。 国内最早的插件式换肤框架是Android-Skin-Loader。后面也出现了一些在此基础上的改进版，比如：hongyang的ChangeSkin，andSkin，Android-skin-support，injor，QSkinLoader

hi,lz 你的这个库用了,相当不错,感谢分享! 现在在看代码的时候,发现SkinManager的init函数中,调用load,我理解这个意思是去加载上次设置的皮肤,但是看下来init的时候,mSkinAttrMap这个值一直都是空的,所以初始化的时候是不会去加载皮肤的,init里面调用load就没有意义了,不知道我理解的对不对,希望lz有空能回复我,再次感谢!

不是这样的，init()中的load方法是初始化资源插件apk的Resource对象，这个对象是换肤的核心，换肤的根本就是更换这个Resource。而mSkinAttrMap存在的根本目的是为了换肤后界面立即生效，而不需要重启应用才生效，是用来记录当前正在显示的需要换肤的view。应用刚刚启动，一个view都没有，mSkinAttrMap肯定为空。

我想咨询一下，为什么在api 28上设置完主题，我在进程杀死app，在打开应用发现还是之前默认的主题，并没有设置成功， 如下是log，应该是28api禁用反射的提示，和这些翻身禁用 有关系么？ java.lang.NoSuchFieldException: No field ProgressBar_indeterminateDrawable in class Ljava/lang/Object; (declaration of 'java.lang.Object' appears in /system/framework/core-oj.jar) 2019-08-01 11:19:42.050 21242-21242/?

hello，，这个框架对 fragment的支持需要自己重新定义baseFragment吧????目前lib包里没有直接可以继承的类吧；

不需要重新定义baseFragment，inflateView的时候更换LayoutInflater就行了。

你这个框架 多次调用SkinManager.get().loadSkin()放法会导致内存中的重复的Bitmap越来越多，Bitmap得不到释放。在性能低得手机上或者模拟器上，内存溢出。我不知道怎么解决，希望博主能给出解决方案，日志我给博主贴出来： java.lang.OutOfMemoryError: Failed to allocate a 31415052 byte allocation with 5935784 free bytes and 5MB until OOM at dalvik.system.VMRuntime.newNonMovableArray(Native Method) at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method) at android.graphics.BitmapFactory.decodeStream(BitmapFactory.java:620) at android.graphics.BitmapFactory.decodeResourceStream(BitmapFactory.java:455) at android.graphics.drawable.Drawable.createFromResourceStream(Drawable.java:1155) at android.content.res.ResourcesImpl.loadDrawableForCookie(ResourcesImpl.java:720) at android.content.res.ResourcesImpl.loadDrawable(ResourcesImpl.java:571) at android.content.res.Resources.getDrawable(Resources.java:771) at com.box.aiqu.util.xskinloader.impl.SkinResourceManagerImpl.getDrawable(SkinResourceManagerImpl.java:135) at com.box.aiqu.util.xskinloader.skinDeployer.ImageDrawableResDeployer.deploy(ImageDrawableResDeployer.java:29) at com.box.aiqu.util.xskinloader.SkinManager.doSkinAttrsDeploying(SkinManager.java:238) at com.box.aiqu.util.xskinloader.SkinManager.deployViewSkinAttrs(SkinManager.java:230) at com.box.aiqu.util.xskinloader.SkinManager.notifySkinChanged(SkinManager.java:217) at com.box.aiqu.util.xskinloader.SkinManager.doNewSkinLoad(SkinManager.java:172) at com.box.aiqu.util.xskinloader.SkinManager.loadNewSkin(SkinManager.java:89) at com.box.aiqu.util.xskinloader.SkinManager.loadSkin(SkinManager.java:78) at com.box.aiqu.util.ChangeSkinUtil.changeSkin(ChangeSkinUtil.java:18)

WeakHashMap没有及时释放view导致的问题，需要根据view的生命周期，管理WeakHashMap中的view

为什么调用SkinManager.get().loadSkin()方法的时候释放不掉内存呢，我看调用一次这个方法内存里就会多一个相同的Bitmap对象。有没有什么方法可以不用根据view的生命周期来管理WeakHashMap中的view，当调用框架SkinManager.get().loadSkin()方法的时候自动释放内存
