项目地址：ChangeMode

Implementation of night mode for Android.

用最简单的方式实现夜间模式，支持ListView、RecyclerView。

Preview

Usage xml

android:background="?attr/zzbackground"
app:backgroundAttr="zzbackground"//如果当前页面要立即刷新，这里传入属性名称 比如 R.attr.zzbackground 传 zzbackground 即可
android:textColor="?attr/zztextColor"
app:textColorAttr="zztextColor"//如需立即刷新页面效果 同上

java

@Override
protected void onCreate(Bundle savedInstanceState) {
//1. 在要立即切换效果的页面调用此方法
ChangeModeController.getInstance().init(this,R.attr.class).setTheme(this, R.style.DayTheme, R.style.NightTheme);
//在其他页面调用此方法 
//ChangeModeController.setTheme(this, R.style.DayTheme, R.style.NightTheme);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//添加额外 view 至夜间管理
// ChangeModeController.getInstance().addBackgroundColor(toolbar, R.attr.colorPrimary);
//ChangeModeController.getInstance().addBackgroundDrawable(view,R.attr.colorAccent);
// ChangeModeController.getInstance().addTextColor(view,R.attr.colorAccent);
//2. 设置切换
//ChangeModeController.changeDay(this, R.style.DayTheme);
//ChangeModeController.changeNight(this, R.style.NightTheme);
}
@Override
protected void onDestroy() {
super.onDestroy();
//3. 在 onDestroy 调用
ChangeModeController.onDestory();
}

详细操作描述

第一步：自定义属性

<?xml version="1.0" encoding="utf-8"?>
<resources>
<attr name="zzbackground" format="color|reference"/>
<attr name="zzbackgroundDrawable" format="reference"/>
<attr name="zztextColor" format="color"/>
<attr name="zzItemBackground" format="color"/>
</resources>

第二步：配置夜间 style 文件

<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
<item name="windowNoTitle">true</item>
</style>
<!--日间模式 -->
<style name="DayTheme" parent="AppTheme">
<item name="zzbackground">@color/dayBackground</item>
<item name="zzbackgroundDrawable">@drawable/ic_launcher</item>
<item name="zztextColor">@color/dayTextColor</item>
<item name="zzItemBackground">@color/dayItemBackground</item>
</style>
<!--夜间模式 -->
<style name="NightTheme" parent="AppTheme">
<item name="zzbackground">@color/nightBackground</item>
<item name="zzbackgroundDrawable">@color/nightBackground</item>
<item name="zztextColor">@color/nightTextColor</item>
<item name="zzItemBackground">@color/nightItemBackground</item>

<item name="colorPrimary">@color/colorPrimaryNight</item>
<item name="colorPrimaryDark">@color/colorPrimaryDarkNight</item>
<item name="colorAccent">@color/colorAccentNight</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>

为相关属性设置对应模式的属性值：

<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="dayBackground">#F2F4F7</color>
<color name="dayTextColor">#000</color>
<color name="dayItemBackground">#fff</color>
<color name="nightItemBackground">#37474F</color>
<color name="nightBackground">#263238</color>
<color name="nightTextColor">#fff</color>
</resources>

第三步：在布局文件中配置使用对应属性

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:background="?attr/zzbackground"
app:backgroundAttr="zzbackground"
tools:context="com.thinkfreely.changemode.MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:backgroundAttr="colorPrimary"
app:titleTextColor="?attr/zztextColor"
app:popupTheme="@style/AppTheme.PopupOverlay"
/>
</android.support.design.widget.AppBarLayout>
<Button
android:layout_width="match_parent"
android:layout_height="120dp"
android:gravity="center"
android:textColor="?attr/zztextColor"
app:textColorAttr="zztextColor"
android:background="?attr/zzItemBackground"
app:backgroundAttr="zzItemBackground"
android:padding="10dp"
android:layout_marginBottom="8dp"
android:textSize="22sp"
android:textAllCaps="false"
android:text="夜间模式切换 by Mr.Zk" />
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"/>
</LinearLayout>

注意textColorAttr、backgroundAttr、backgroundDrawableAttr三个属性。如需当前页面立即刷新，需填加相应属性。

属性 描述

textColorAttr 修改字体颜色时设置。如 R.attr.zztextColor 传 zztextColor 即可。例:app:textColorAttr="zztextColor"
backgroundAttr 修改背景颜色/背景图片时设置。同上。例: app:backgroundAttr="zzbackground"
backgroundDrawableAttr 修改背景颜色/背景图片时设置。同上。例: app:backgroundDrawableAttr="zzbackground"

第四步：页面调用 java 代码

@Override
protected void onCreate(Bundle savedInstanceState) {
//1. 在要立即切换效果的页面调用此方法
ChangeModeController.getInstance().init(this,R.attr.class).setTheme(this, R.style.DayTheme, R.style.NightTheme);
//在其他页面调用此方法 
//ChangeModeController.setTheme(this, R.style.DayTheme, R.style.NightTheme);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//2.设置切换夜间活日间模式
//ChangeModeController.changeDay(this, R.style.DayTheme);//切换日间模式
//ChangeModeController.changeNight(this, R.style.NightTheme);//切换夜间模式
}
@Override
protected void onDestroy() {
super.onDestroy();
//3. 在 onDestroy 调用
ChangeModeController.onDestory();
}

代码调用三步，即可开始夜间之旅。 如果页面有新创建的视图要加入夜间模式控制，代码调用：

//添加额外 view 至夜间管理
// ChangeModeController.getInstance().addBackgroundColor(toolbar, R.attr.colorPrimary);
//ChangeModeController.getInstance().addBackgroundDrawable(view,R.attr.colorAccent);
// ChangeModeController.getInstance().addTextColor(view,R.attr.colorAccent);

如果在改变夜间模式时有其他非标准定义的属性时，可在ChangeModeController.changeDay或ChangeModeController.changeNight之后调用如下代码给相关属性赋值：

TypedValue attrTypedValue = ChangeModeController.getAttrTypedValue(this, R.attr.zztextColor);
toolbar.setTitleTextColor(getResources().getColor(attrTypedValue.resourceId));
