三行Android代码实现白天夜间模式流畅切换

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 

 @Override protected void onCreate(Bundle savedInstanceState) {   // 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);  // 设置切换  //ChangeModeController.changeDay(this, R.style.DayTheme);  //ChangeModeController.changeNight(this, R.style.NightTheme); }    @Override protected void onDestroy() {  super.onDestroy();  // 在onDestroy调用  ChangeModeController.onDestory(); }
