Android Material Design系列之夜间模式 阐述了夜间模式的资源文件，告知建立了values-night文件夹
对于夜间模式的颜色和主题配置，我们需要建立一个res下建立一个values-night文件夹，里面放着夜间主题样式的color等资源。
colors.xml配置如下：
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorPrimary">#0a0a0a</color>
<color name="colorPrimaryDark">#000000</color>
<color name="colorAccent">#fc0404</color>
<color name="add_bg_color">#FF2ECC71</color>
<color name="add_selected_color">#51C332</color>
<color name="white">#ffffff</color>
<color name="text_color">#7f7f7f</color>
<color name="navigation_bar_color">#0a0a0a</color>
<color name="color_control_normal">#f305be</color>
<color name="text_color_primary">#00ffff</color>
<color name="navigationview_bg_color">#000000</color>
</resources>切换主体
isNight = sp.getBoolean("night", false);
if (isNight) {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);
sp.edit().putBoolean("night", false).commit();
} else {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
sp.edit().putBoolean("night", true).commit();
}

/**
* Night Mode Helper
* <p>
* Helps use utilise the night and notnight resource qualifiers without being in car or dock mode.
* <p>
* Implementation is simple. Add the follow line at the top of your activity's onCreate just after
* the super.onCreate(); The idea here is to do it before we create any views. So the new views will
* use the correct Configuration.
*
* <pre>
* mNightModeHelper = new NightModeHelper(this, R.style.AppTheme);
* </pre>
*
* You can now use your instance of NightModeHelper to control which mode you are in. You can choose
* to persist the current setting and hand it back to this class as the defaultUiMode, otherwise
* this is done for you automatically.
* <p>
* I'd suggest you setup your Theme as follows:
* <ul>
* <li><b>res\values\styles.xml</b>
*
* <pre>
* <style name="AppTheme" parent="AppBaseTheme"></style>
* </pre>
*
* </li>
* <li><b>res\values-night\styles.xml</b>
*
* <pre>
* <style name="AppBaseTheme" parent="@android:style/Theme.Holo"></style>
* </pre>
*
* </li>
* <li><b>res\values-notnight\styles.xml</b>
*
* <pre>
* <style name="AppBaseTheme" parent="@android:style/Theme.Holo.Light"></style>
* </pre>
*
* </li>
* </ul>

4.android夜间模式浅析
- 定义DayNight主体，以及相关属性
<style name="AppTheme" parent="Theme.AppCompat.DayNight.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style><?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorPrimary">#3F51B5</color>
<color name="colorPrimaryDark">#303F9F</color>
<color name="colorAccent">#FF4081</color>
</resources>- 在res下面创建values-night文件夹，创建colors.xml声明color属性
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="colorPrimary">#1f2023</color>
<color name="colorPrimaryDark">#18181a</color>
<color name="colorAccent">#FF4081</color>
</resources>- 为程序设置初始模式
MODE_NIGHT_NO. 使用亮色（light）主题
MODE_NIGHT_YES. 使用暗色（dark）主题
MODE_NIGHT_AUTO. 根据当前时间自动切换 亮色（light）/暗色（dark）主题
MODE_NIGHT_FOLLOW_SYSTEM(默认选项). 设置为跟随系统，通常为 MODE_NIGHT_NO- 在Application中进行初始化
public class MyApplication extends Application {
static {
AppCompatDelegate.setDefaultNightMode(
AppCompatDelegate.MODE_NIGHT_NO);
}
@Override
public void onCreate() {
super.onCreate();
}
}- 在初始化就切换夜间模式
public class MyApplication extends Application {
static {
AppCompatDelegate.setDefaultNightMode(
AppCompatDelegate.MODE_NIGHT_NO);
}
@Override
public void onCreate() {
super.onCreate();
}
}- 获取当前主体的状态
int currentNightMode = getResources().getConfiguration().uiMode
& Configuration.UI_MODE_NIGHT_MASK;
case Configuration.UI_MODE_NIGHT_NO:
case Configuration.UI_MODE_NIGHT_YES:
case Configuration.UI_MODE_NIGHT_UNDEFINED:- 通过主体确定
int currentNightMode = getResources().getConfiguration().uiMode
& Configuration.UI_MODE_NIGHT_MASK;
switch (currentNightMode) {
case Configuration.UI_MODE_NIGHT_NO:
getDelegate().setDefaultNightMode(
AppCompatDelegate.MODE_NIGHT_YES);
break;
case Configuration.UI_MODE_NIGHT_YES:
getDelegate().setDefaultNightMode(
AppCompatDelegate.MODE_NIGHT_NO);
break;
case Configuration.UI_MODE_NIGHT_UNDEFINED:
getDelegate().setDefaultNightMode(
AppCompatDelegate.MODE_NIGHT_AUTO);
break;
}
// 调用 recreate() 使设置生效
recreate();
