ThemeUtil.java

package com.example.gitshiyan01;

import android.app.Activity;
import android.content.Intent;

/**

 */

public class ThemeUtil {

    //我当前应用的主题
    private static int theme = 0;

    //日间模式主题
    private static final int DAY_THEME = 0;

    //夜间模式主题
    private static final int NIGHT_THEME = 1;

    public static void onActivityCreatedSetTheme(Activity activity) {
        switch (theme) {
            case DAY_THEME:
                activity.setTheme(R.style.day_theme);
                break;
            case NIGHT_THEME:
                activity.setTheme(R.style.night_theme);

    //点击按钮改变对应得主题
    public static void ChangeCurrentTheme(Activity activity) {

        //1、改变当前主题的theme变量
        switch (theme) {

        //2、重启这个activity
        activity.finish();
        activity.overridePendingTransition(R.anim.sliding_in, R.anim.sliding_out);
        activity.startActivity(new Intent(activity, activity.getClass()));
    }
}

在res目录下创建anim文件夹

sliding_in.xml

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:fromAlpha="0.0"

sliding_out.xml

<?xml version="1.0" encoding="utf-8"?>

    android:duration="1000"
    android:toAlpha="0.0"
    android:fromAlpha="1.0"></alpha>

在values目录下创建attrs

attrs.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <attr name="textColorValue" format="color"></attr>
    <attr name="textContent" format="string"></attr>
