如果在网上搜换肤，方案五花八门，但是根据app的需求，以及无设计师的情况下，基本上简约风格app,这种风格下只需要几个颜色就行了，根本不需要动态从磁盘加载皮肤apk,而且通过反射操作侵入性太强，因此attr大法才是最适合目前的我所做的app实现。

网上的换肤方法侵入性太强，而纯色app不需要各种花式的皮肤，基本上2三套颜色就行了，主色，次色，而其他则非黑即白。深色模式实现就更简单了，用着色tint就实现了。

经过了几天的研究发现，动态修改setTheme是有bug的， bug就是状态栏颜色和actionbar在未在activity定义attr背景的情况下实现修改actionbar的就有这个bug,2015年在stackoverflow网站上就有人提出解决方法，这个解决方法是没有办法的方法，需要在baseactivity进行判断，如果有actionbar就设置actionbar颜色，

以及设置状态栏颜色。

达到的效果

在颜色选择器中是可以直接使用实现的属性?attr
而在drawable,则需要包裹一层drawable引用color，直接使用color属性也是会报错的，
正常的按钮，对话框，控件不需要再通过代码，xml设置颜色，

而网上的操作性太麻烦，正规的写法就是官方的写法，能不在view xml定义的就不在view xml定义
这样侵入性比较小。

颜色主题需要注意的事项

drawable要使用颜色属性只能包裹一层shape

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="?attr/defaultThemeColorSecond"/>
</shape>

第三方自定义ui 有的是只支持颜色不支持attr的。则需要进行额外适配处理，
其处理方式就是根据属性查找对应的颜色 或者id (colorres)
颜色属性找颜色

    public static int attrFetchColor(Context context,int attrColor) {
        int[] attribute = new int[]{attrColor};
        TypedArray array =context.getTheme().obtainStyledAttributes(attribute);
        int color = array.getColor(0, AppContext.getInstance().getResources().getColor(R.color.themeColor));
        array.recycle();
        return color;
    }

查找id

  public static int attrFetchColorId(Context context,int attrColor) {
        int[] attribute = new int[]{attrColor};
        TypedArray array = context.obtainStyledAttributes(attribute);
        int colorID = array.getResourceId(0, R.color.themeColor);
        array.recycle();
        return colorID;
    }

在baseactivity onCreate中修改状态栏颜色

    public static void updateActionBarAndStatusColor(Activity activity) {
        if (activity instanceof AppCompatActivity) {
            AppCompatActivity appCompatActivity = (AppCompatActivity) activity;
            ActionBar supportActionBar = appCompatActivity.getSupportActionBar();
            if (supportActionBar != null) {
                int i = AppUtils.attrFetchColor(activity,R.attr.defaultThemeColor);
                supportActionBar.setBackgroundDrawable(new ColorDrawable(i));
            }

        }
        android.app.ActionBar actionBar = activity.getActionBar();
        if (actionBar != null) {
            int color = AppUtils.attrFetchColor(activity,R.attr.defaultThemeColor);
            actionBar.setBackgroundDrawable(new ColorDrawable(color));
        }

        if (Build.VERSION.SDK_INT >= 21) {
//            getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
//            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
            int statusBarBackground = AppUtils.attrFetchColor(activity,R.attr.colorPrimaryDark);


            Window window = activity.getWindow();
//            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
//            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
//            window.setStatusBarColor(backgroundColor);
            window.setStatusBarColor(statusBarBackground);
        }


    }

主题修改代码

 getBinding().rlMyThemeSetting.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
                int currentMode = NightModeUtils.Companion.getSpfThemeMode(AppContext.getInstance());
                ThemeMode[] values = ThemeMode.values();
                CharSequence[] items=new CharSequence[values.length];
                for (int i = 0; i < values.length; i++) {
                    String title = AppContext.getInstance().getString(values[i].getStringValueId());
                    items[i]=title;
                }
                builder.setSingleChoiceItems(items, currentMode, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        if (which != currentMode) {
                            dialog.dismiss();
                            ThemeMode value = values[which];
                            NightModeUtils.getInstance(AppContext.getInstance()).setThemeMode(value);
                            EventBus.getDefault().post(new ThemeChangeEvent().themeChange());

                        }

                    }

                });
                builder.setTitle(AppContext.getStr(R.string.deep_color_theme_setting));
                builder.show();

            }
        });

收到事件进行recreate(); ，我这里是在mainact,mainact可直接recreate,无需finish
适配起来挺快的，通过各种批量替换
但是需要注意的是，第三方对颜色适配做的很烂，哪怕大家众所周知的smartrefresh也不支持属性引用颜色。 因此主要的适配就是处理第三方框架的问题，
这个适配工作基本上一天就搞定了。
另外花的实际是纠结研究为啥actionbar和状态栏颜色通过setTheme无效花费了很多时间，在attach里面替换，以及研究theme的各种方法，以及引用再引用的方式也解决不了问题，
最后既然无效我只能另外走方法了，强制设置。

attr.xml定义

    <attr name="defaultThemeColor" format="reference|color"></attr>
    <attr name="defaultThemeColorSecond" format="reference|color"></attr>

其实现在每一个主题都实现了，

下面附上theme.xml 仔细看 都实现了defaultThemeColor defaultThemeColorSecond 属性，

如果不为0，

    if (color != 0) {
//            getTheme().applyStyle(color, true);
            AppUtils.updateActionBarAndStatusColor(this);
        }

另外补充一点，按钮这些一般我都没有修改在每一个activity xml设置的，遵循material design以及theme的写法，全局就可以进行操作的，在<item name="colorPrimary">就完成了适配，
主要的适配工作还是处理selector的颜色以及第三方框架引用了颜色的情况，另外处理深色兼容的适配。

另外关于重启生效的事情，recreate也是只能修改部分颜色而在我自己曾经写的一款app没有这样的问题，经过比较发现，我的那个app没有一个app是额外指定了主题的，所以状态栏颜色等都能自动马上生效，而且不需要通过代码修改状态栏颜色，因此这个bug是act的xml定义的主题和代码设置的主题冲突bug.

关于This Activity already has an action bar supplie

 This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.
                                                                                                        at androidx.appcompat.app.AppCompatDelegateImpl.setSupportActionBar(Ap

如果在actionbar已经在xml中指定的情况（如果act没有指定则从application节点继承），在代码里面继续设置是会报错的，可在setContentView代码之前调用setTheme指定不包含actionbar的解除actionbar
则调用setSupportActionBar不会抛出已设置的错误。
setSupportActionBar的作用是把布局xml中的toolbar 依附到act中。

关于状态栏通过setTheme recreate有些东西不生效 ，重启不生效的原因 最根本原因是使用了MaterialComponents 主题而不是Theme.AppCompat，但是不使用MaterialComponents主题会导致google的组件样式无法全局生效，这是个矛盾，而且导致我的app大量崩溃，都是因为google的组件问题。
然后我继续找问题，还是改成了MaterialComponents主题，发现recreate又没有bug了，可以不重启全部更新。 之前又不行，我搞的精神崩溃了，也许是编译缓存问题？？。。
总之最后通过recreate可以实现当前界面更新状态栏，不过第二个界面则不行，需要代码设置。不过体验比之前好了，不需要彻底重启app,由于保存了状态，基本上切换主题就感觉没有重启act的感觉，实际上是重建了的。

最后的最后我发现深色切换 回来或者切换过去，会导致很多地方不生效，比如状态栏，部分背景，
在recreate执行之前重新设置一遍主题可以解决此问题

    if (which != currentMode) {
                            dialog.dismiss();
                            ThemeMode value = values[which];
                            NightModeUtils.getInstance(AppContext.getInstance()).setThemeMode(value);
                            if (currentMode == 0 || which == 0) {//如果是从深色切换过来的就需要先执行setTheme，也就是执行了2次。
                                NightModeUtils.getInstance(getContext()).applySetting(getContext());
                                getActivity().recreate();
                            } else {
                                EventBus.getDefault().post(new ThemeChangeEvent().themeChange());

                            }

                        }

最后的最后是这样的

 ThemeMode value = values[which];
                            NightModeUtils.getInstance(AppContext.getInstance()).setThemeMode(value);
                            if (currentMode == 0 || which == 0) {
                                //call setTheme
                                NightModeUtils.getInstance(getContext()).applySetting(getContext());
                                //如果重启会发现部分没生效，深色模式的切换是不需要重启就能生效的
                            } else {
                                getActivity().recreate();
