Android (服务Service)

Android 中有几个重要的组件,其中之一就是Service,这是没有UI的组件,可以做为后台的服务,当然可以使用Intent来启动。同时也可以绑定到宿主对象(调用者,常是Activity)来使用, 注意: 一,Android中的Service与调用者在同一线程,所以要是耗时的操作要在Service中新开线程。 二,Android的Service中,主要是实现其onCreate,onStart, onDestroy,onBind,onUnBind几个函数,来实现我们所需要的功能。 简单的调用: 简单的调可以在调用者对象中使用Context.startService来调用,以Intent为参数,当然,Intent搜索,匹配目标的方式与以前在《Intent使用》中方式一样。 下面来看一段例程: 一,声明Service子类 。 public class TestService extends Service { @Override public void onCreate() { // TODO Auto-generated method stub super.onCreate(); Toast.makeText(this, "Service Created!", Toast.LENGTH_SHORT).show(); } @Override public void onDestroy

浅析vue封装自定义插件

大憨熊 提交于 2020-01-07 13:07:56
  在使用vue的过程中,经常会用到Vue.use,但是大部分对它一知半解,不了解在调用的时候具体做了什么,因此,本文简要概述下在vue中,如何封装自定义插件。   在开始之前,先补充一句,其实利用vue封装自定义插件的本质就是 组件实例化的过程或者指令等公共属性方法的定义过程 ,比较大的区别在于封装插件需要手动干预,就是一些实例化方法需要手动调用,而Vue的实例化,很多逻辑内部已经帮忙处理掉了。 插件相对于组件的优势就是插件封装好了之后,可以开箱即用,而组件是依赖于项目的 。对组件初始化过程不是很熟悉的可以参考 这篇博文 。     我们从vue源码中,可以看到Vue.use的方法定义如下:  Vue.use = function (plugin: Function | Object) { const installedPlugins = (this._installedPlugins || (this._installedPlugins = [])) // 已经存在插件,则直接返回插件对象 if (installedPlugins.indexOf(plugin) > -1) { return this } // additional parameters const args = toArray(arguments, 1) args.unshift(this) //

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> SharedPreferences是Android中最容易理解的数据存储技术,实际上SharedPreferences处理的就是一个key-value(键值对)SharedPreferences常用来存储一些轻量级的数据。 1、使用SharedPreferences保存数据方法如下: //实例化SharedPreferences对象(第一步) SharedPreferences mySharedPreferences= getSharedPreferences("test", Activity.MODE_PRIVATE); //实例化SharedPreferences.Editor对象(第二步) SharedPreferences.Editor editor = mySharedPreferences.edit(); //用putString的方法保存数据 editor.putString("name", "Karl"); editor.putString("habit", "sleep"); //提交当前数据 editor.commit(); //使用toast信息提示框提示成功写入数据 Toast.makeText(this, "数据成功写入SharedPreferences!" , Toast
