Worklight Adapters - Java vs JavaScript

由 泪湿孤枕 提交于 2019-12-13 00:34:17
问题 Is there any drawback to having the JavaScript Worklight adapters calling Java code? Is there a performance hit, or any caveats? The reason I ask, is that 1) I'm much more familiar with Java than JavaScript, and 2) Java is so much more powerful than JavaScript. I'm tempted to just have the adapter always call a Java class to do all the work, but I'm just concerned there might be some reasons I shouldn't. 回答1: Using Java inside of your adapters is meant as "an extension of the adapter function

问题 I would like to undertand how to modify on fly the SSDL in a connection string. I have followed the tutorial here: http://www.codeproject.com/Articles/82017/Preparing-an-Entity-Framework-model-for-multi-prov , but I am still not able to understand how to configure the "res://" line and where to put the .ssdl file. I have a complex hierarchical structure to be compiance to an adapter structure: <project root> / Toolkit / Database / External / Adapter / Abstract.cs / File / File.ssdl / Adapter

How communicate between Adapter and Activity

由 为君一笑 提交于 2019-12-12 17:07:40
问题 I'm not sure what's the best way to communicate from an Adapter to the corresponding Activity. My activity has a layout with a WebView and a Gallery on top of it: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="vertical" > <Gallery android:id="@+id/gallery" android:layout_height="wrap_content" android:layout_weight="1" android:layout_width

How to transfer media files using Worklight

由 回眸只為那壹抹淺笑 提交于 2019-12-12 13:16:42
问题 What's the correct way of transferring media (photos or movies) using Worklight Adapters? I sent a photo via the adapter and got the error: form too large, exceed the maximum size... I read I need to change the form size through the Jetty but the server I'll deploy the app won't be a jetty so what shell i do? Thanks! 回答1: Please see topic Uploading large (and binary) files to Worklight adapter. Basically, Worklight does not have the equivalent to an HTTP POST mechanism that allows you to

what is the need of Adapter Design pattern?

由 北战南征 提交于 2019-12-12 12:18:05
问题 In the below adapter design pattern sample code, why a new class is introduced instead of using multiple interface in the client? interface ITarget { List<string> GetProducts(); } public class VendorAdaptee { public List<string> GetListOfProducts() { List<string> products = new List<string>(); products.Add("Gaming Consoles"); products.Add("Television"); products.Add("Books"); products.Add("Musical Instruments"); return products; } } class VendorAdapter:ITarget { public List<string>

适配器模式（Adapter模式）

由 巧了我就是萌 提交于 2019-12-12 11:42:42
在现实生活中，经常出现两个对象因接口不兼容而不能在一起工作的实例，这时需要第三者进行适配。例如，讲中文的人同讲英文的人对话时需要一个翻译，用直流电的笔记本电脑接交流电源时需要一个电源适配器，用计算机访问照相机的 SD 内存卡时需要一个读卡器等。 在软件设计中也可能出现：需要开发的具有某种业务功能的组件在现有的组件库中已经存在，但它们与当前系统的接口规范不兼容，如果重新开发这些组件成本又很高，这时用适配器模式能很好地解决这些问题。 模式的定义与特点 适配器模式（Adapter）的定义如下：将一个类的接口转换成客户希望的另外一个接口，使得原本由于接口不兼容而不能一起工作的那些类能一起工作。适配器模式分为类结构型模式和对象结构型模式两种，前者类之间的耦合度比后者高，且要求程序员了解现有组件库中的相关组件的内部结构，所以应用相对较少些。 该模式的主要优点如下。 客户端通过适配器可以透明地调用目标接口。 复用了现存的类，程序员不需要修改原有代码而重用现有的适配者类。 将目标类和适配者类解耦，解决了目标类和适配者类接口不一致的问题。 其缺点是：对类适配器来说，更换适配器的实现过程比较复杂。 模式的结构与实现 类适配器模式可采用多重继承方式实现，如 C++ 可定义一个适配器类来同时继承当前系统的业务接口和现有组件库中已经存在的组件接口；Java 不支持多继承

When I scroll a listview with a custom adapter too fast up and down, getView() starts behaving oddly. Why?

由 拜拜、爱过 提交于 2019-12-12 08:53:50
问题 I have a listview with a custom arrayadapter that handles about 15 strings. The style of each row alternates (between labels and values for those labels--for example row 1 could be "email address" and row 2 would be the actual email address). I'm changing the style of each row to alternate like this in the arrayadapter's getView() method. So if the item at the current position is a label, I'll change the styling from the default row style (which is what the values have applied to them). When

Android: Change Button background in ListView Row with onClick

由 时光毁灭记忆、已成空白 提交于 2019-12-12 08:47:34
问题 My rows contain a button that has its own click listener set in my adapter's getView. I'm able to distinguish between my button clicks and the actual row item clicks using android:descendantFocusability="blocksDescendants" in the row's parent. When I click on a button it sets the button background properly, my problem is as I scroll through the list its setting it for different rows as well. I assume theirs an issue somewhere with views recycling. Here's my code: @Override public View getView
