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();
}
recreate();

2. 夜间模式工具类

import android.app.Activity;
import android.content.SharedPreferences;
import android.content.res.Configuration;
import android.preference.PreferenceManager;

import java.lang.ref.WeakReference;

/**
 * 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>
 * &lt;style name=&quot;AppTheme&quot; parent=&quot;AppBaseTheme&quot;&gt;&lt;/style&gt;
 * </pre>
 * 
 * </li>
 * <li><b>res\values-night\styles.xml</b>
 * 
 * <pre>
 * &lt;style name=&quot;AppBaseTheme&quot; parent=&quot;@android:style/Theme.Holo&quot;&gt;&lt;/style&gt;
 * </pre>
 * 
 * </li>
 * <li><b>res\values-notnight\styles.xml</b>
 * 
 * <pre>
 * &lt;style name=&quot;AppBaseTheme&quot; parent=&quot;@android:style/Theme.Holo.Light&quot;&gt;&lt;/style&gt;
 * </pre>
 * 
 * </li>
 * </ul>

android夜间模式浅析

1. 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>

2. 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>

3. 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

4. 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();
	}

}

5. 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();
}

}

6. 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:

7. 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();
}
