Android开发常用之日夜主题切换

前言：

        1.主题切换需要了解 attr 和？attr的区别，style的使用，intent对象的flag ，SharedPreferences和enum
的使用。

        2.需要准备日夜对应控件颜色配置。

步骤：

        1.创建light theme和Dark Theme。

        2.创建SharePreferenceManager

        3.编写配置类，切换和保存主题。

        4.在需要切换的地方使用intent对象flag实现切换

一。创建light theme和Dark Theme

</style>
<style name="LightTheme" parent="LightTheme.Base">
</style>
<style name="DarkTheme" parent="DarkTheme.Base">
</style>

二。创建SharePreferenceManager和配置类，切换和保存主题

  public static SharedPreferences getApplicationSetting(Context context){
    return context.getSharedPreferences(ApplicationSetting.FILE_NAME, Context.MODE_PRIVATE);
}
/**
 * 应用配置首选项, 保存主题...一些系统级别的配置
 */
public static class ApplicationSetting{
    public static final String FILE_NAME = "APPLICATION_SETTING";
    public static final String KEY_THEME = "KEY_THEME";
     // ---主题列举---
    public enum ApplicationTheme{
        LIGHT(1, R.style.LightTheme),
        DARK(2, R.style.DarkTheme);
        private int key;
        private int resId;
        ApplicationTheme(int key, int resId){
            this.key = key;
            this.resId = resId;
        }
        public int getKey() {
            return key;
        }
        public int getResId() {
            return resId;
        }
    }
}

三。在需要切换的地方使用intent对象flag实现切换

SharedPreferences preferences = SharePreferenceManager.getApplicationSetting(this);
int theme = preferences.getInt(SharePreferenceManager.ApplicationSetting.KEY_THEME, SharePreferenceManager.ApplicationSetting.ApplicationTheme.LIGHT.getKey());
SharedPreferences.Editor editor = preferences.edit();
if (theme == SharePreferenceManager.ApplicationSetting.ApplicationTheme.LIGHT.getKey()){
    editor.putInt(SharePreferenceManager.ApplicationSetting.KEY_THEME, SharePreferenceManager.ApplicationSetting.ApplicationTheme.DARK.getKey());
}else{
    editor.putInt(SharePreferenceManager.ApplicationSetting.KEY_THEME, SharePreferenceManager.ApplicationSetting.ApplicationTheme.LIGHT.getKey());
}
editor.apply();
finish();
Intent intent = getIntent();
intent.putExtra(CHANGE_THEME, true);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
overridePendingTransition(R.anim.enter, R.anim.exit);

enter:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <alpha android:fromAlpha="0" android:toAlpha="1" android:duration="1000"/>
</set>

exit:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <alpha android:fromAlpha="1" android:toAlpha="0" android:duration="1000"/>
</set>

xml布局文件引用style颜色：

测拉菜单：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.LinearLayoutCompat xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="@dimen/drawer_height"
    android:orientation="vertical"
    android:background="?attr/drawer_header_background"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin">
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp">
        <de.hdodenhof.circleimageview.CircleImageView
            android:id="@+id/iv_portrait"
            android:layout_width="70dp"
            android:layout_height="70dp"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true"
            android:layout_alignParentTop="true"
            android:contentDescription="@null"
            android:src="@mipmap/icon_default_portrait" />
        <ImageView
            android:id="@+id/iv_exit"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentEnd="true"
            android:layout_alignParentRight="true"
            android:contentDescription="@null"
            android:src="@mipmap/icon_exit" />
    </RelativeLayout>
    <TextView
        android:id="@+id/tv_nick"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:drawablePadding="5dp"
        android:textColor="?attr/drawer_header_username"
        android:textSize="@dimen/drawer_header_username" />
    <TextView
        android:id="@+id/tv_score"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</android.support.v7.widget.LinearLayoutCompat>

toolbar:

<android.support.design.widget.CoordinatorLayout
    android:id="@+id/layout_coordinator"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <android.support.design.widget.AppBarLayout
        android:id="@+id/layout_actionbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:elevation="0dp">
        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light">
        </android.support.v7.widget.Toolbar>
    </android.support.design.widget.AppBarLayout>

总结：

    这个方法思路简单，颜色配置有些麻烦，适用于小中型项目开发。
