2E04-view-lists-slow-efficient-adapter

介绍自定一个的Adapter和list的监听

注意

1.LayoutInflater mInflater初始化的位置

2.getview method 中多convertView不为空的判断

3.list的touch scroll ,Filing,Idle监听

4.比较第一个(低效)和第二个(高效)在getiew中的不同实现

低效的实现的listView

/**
 * Demonstrates how to write an efficient list adapter. The adapter used in this example binds
 * to an ImageView and to a TextView for each row in the list.
 *
 * To work efficiently the adapter implemented here uses two techniques:
 * - It reuses the convertView passed to getView() to avoid inflating View when it is not necessary
 * - It uses the ViewHolder pattern to avoid calling findViewById() when it is not necessary
 *
 * The ViewHolder pattern consists in storing a data structure in the tag of the view returned by
 * getView(). This data structures contains references to the views we want to bind data to, thus
 * avoiding calls to findViewById() every time getView() is invoked.

Adapter数据变化改变现有View的实现原理及案例

首先说说Adapter具体的类的继承关系,如下图 Adapte为接口它的实现类的对象作为AdapterView和View的桥梁,Adapter是装载了View(比如ListView和girdView要显示的数据).相关View要显示的数据完全与View解耦.View要显示的数据从Adapter里面获取并展现出来:Adapter负责把真实的数据是配成一个个View(每一条数据对应一个View)让GirdView等类似的组件来显示这些是配好的一个个View,.也就是说View要显示什么数据取决于Ad

ApiDemos--&gt;Views-lists-slow adapter学习

今天来按照apidemos提供的方法来实现slow loading的效果. 简单说下实现方法: 实现ListView.OnScrollListener ,监听到手势滑动的情况,当处于滚动状态时,将新显示的items 设置为Loading , 当离开屏幕时,才加载真实的数据. 设置数据时,要用到getFirstVisiblePosition属性来计算应该加载第几个item. 该小demo应该算是学习Android AsyncTask异步加载的基础. Main.java import android

Android自定义Viewgroup切换View带有吸附效果

1.概述 先上效果图 大概就是这个效果,先说说实现思路 1.首先我们要拿到图片的url(网络)或id.路径(本地),将View与数据进行绑定,写我们自己的Adapter 2.自定义Viewgroup将要显示的view进行布局,以及处理触摸事件进行逻辑处理 3.写切换回调 2.实现 1)自定义Adapter 这里我下载的网络图片,同样可以将图片放到res下设置ImageView的内容 public class DragPageViewAdapter { private static final S

【单页应用】view与model相关梳理

前情回顾 根据之前的学习,我们形成了一个view与一个messageCenterview这块来说又内建了一套mvc的东西,我们这里来理一下首先View一层由三部分组成:① view② dataAdpter③ viewController view一块两个重要数据是模板以及对应data,一个状态机status这里view只负责根据状态取出对应的模板,而后根据传入的数据返回组装好的html这里一个view多种状态是什么意思呢?比如我有一个组件,但是里面有一圈数据是需要Ajax请求的,所以我的view

ListView中不同类型view的实现

首先创建请求队列,一个活动中只需要一个,因此放在Application中: public class MyApplication extends Application{ private static RequestQueue requestQueue; @Override public void onCreate() { super.onCreate(); requestQueue = Volley.newRequestQueue(getApplicationContext()); } pub

Android通用Adapter使用例子

Android中Adapter如果继承自BaseAdapter的话必须实现一下四个方法 getCount(); getItem(int position); getItemId(int position); getView(int position, View convertView, ViewGroup parent); 其实每个adapter真正变化的部分就是getView方法.这里用于控制每个Item显示出来的效果. 所以我自定义了一个BaseAdapter,叫做AppBaseAdapte
