adapter

Does Android's class BaseAdapter have "Adapter" in its name because it follows the Adapter pattern or is it just a coincidence? From Wikipedia In computer programming, the adapter pattern (often referred to as the wrapper pattern or simply a wrapper) is a design pattern that translates one interface for a class into a compatible interface. 1 An adapter allows classes to work together that normally could not because of incompatible interfaces, by providing its interface to clients while using the original interface. So, let's discect that. BaseAdapters specify an interface to use for programs

I have a editext for search in a list view. I want to check if listview adapter is filtered by any text or not. Here is my code: Button search=(Button)findViewByld(R.id.bsearch); search.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { MainActivity.this.adapter.getFilter().filter(inputSearch.getText().toString()); //HERE IS MY PROBLEM if(adapter was filtered by a text) { // Do some things } }}); } } Hope to get my purpose. Thanks a lot. Filter has a overridden method with Filter.FilterListener which you can use . search.setOnClickListener(new OnClickListener()

JMX JMX的全称为Java Management Extensions. 顾名思义，是管理Java的一种扩展。这种机制可以方便的管理、监控正在运行中的Java程序。常用于管理线程，内存，日志Level，服务重启，系统环境等 基本术语 MBean： 是Managed Bean的简称，可以翻译为“管理构件”。在JMX中MBean代表一个被管理的资源实例，通过MBean中暴露的方法和属性，外界可以获取被管理的资源的状态和操纵MBean的行为。事实上，MBean就是一个Java Object，同JavaBean模型一样，外界使用自醒和反射来获取Object的值和调用Object的方法，只是MBean更为复杂和高级一些。MBean通过公共方法以及遵从特定的设计模式封装了属性和操作，以便暴露给管理应用程序。例如，一个只读属性在管理构件中只有Get方法，既有Get又有Set方法表示是一个可读写的属性。一共有四种类型的MBean: Standard MBean, Dynamic MBean, Open MBean, Model MBean。 MBeanServer： MBean生存在一个MBeanServer中。MBeanServer管理这些MBean，并且代理外界对它们的访问。并且MBeanServer提供了一种注册机制，是的外界可以通过名字来得到相应的MBean实例。 JMX Agent：

i've built an http adapter that call a soap web service ==> it works fine. But when i add a xsl transformation file and run the adapter procedure with transformation : { type : 'xslFile', xslFile : 'filtered.xsl' } and an empty xsl file <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:h="http://www.w3.org/1999/xhtml"> <xsl:output method="text"/> <xsl:template match="/"> </xsl:template> i've got the following error: "Ecma Error: TypeError: Cannot read property \"Body\" from undefined The xml returned by the web service is OK (checked with WireShark).
