android调用接口,android 接口
android端怎么调用webservice接口
在Android平台调用Web Service需要依赖于第三方类库ksoap2,它是一个SOAP Web service客户端开发包,主要用于资源受限制的Java环境如Applets或J2ME应用程序(CLDC/ CDC/MIDP)。认真读完对ksoap2的介绍你会发现并没有提及它应用于Android平台开发,没错,在Android平台中我们并不会直接使用ksoap2,而是使用ksoap2 android。KSoap2 Android 是Android平台上一个高效、轻量级的SOAP开发包,等同于Android平台上的KSoap2的移植版本。
我们提供的服务有:做网站、成都做网站、微信公众号开发、网站优化、网站认证、海丰ssl等。为成百上千企事业单位解决了网站和推广的问题。提供周到的售前咨询和贴心的售后服务,是有科学管理、有技术的海丰网站制作公司

android 接口类调用问题
1、对应一个接口即可,比如OnMsgChangeListener,代码:
public interface OnMsgChangeListener {
public void doMsg(MsgBean bean);
}
2、定义MsgBeanActivity处理MsgBean数据
3、定义MsgBean实体
4、在MsgBeanActivity定义setMsgChangeListener()方法,传入的OnMsgChangeListener接口对象,如下代码:
setMsgChangeListener(OnMsgChangeListener onMsg)
5、重写接口方法
Android APP调用第三方接口
首先要知道第三方App的activity的包名和启动Activity是哪一个,然后可以通过包名直接调用起来。当然Intent的时候要注意设置Flag是NewTask
Android接口回调总结,以及运用到弹窗PopWindow的Demo实现
最近项目中接触到接口回调,以及Android弹窗PopWindow组件的使用,现在利用学到的知识自己写了一个简单的Demo,练习下在Android下如何运用接口回调,来实现弹窗PopWindow的功能。
1. 定义一个接口:OnSelectItemListener。定义一个方法 void selectItem(String name, int type),作为点击弹窗的每个Item的回调接口。
2. 自定义弹窗类:MyPopupWindow,其布局文件为popup_window.xml。当在MainActivity调用其构造函数创建对象时,同时执行initPopupWindow()函数,给每个Item设置监听器,监听点击Item时,回调接口函数selectItem("Pop Window A", POP_WINDOW_ITEM_1),该函数在MainActivity中实现。
3. 主Activity: MainActivity。其布局文件为一个Button和一个TextView。监听Button,每当点击则弹出PopWindow,呈现三个Item。调用MyPopupWindow类中的方法setOnSelectItemListener(OnSelectItemListener listener),传入OnSelectItemListener 对象作为参数,同时实现回调接口OnSelectItemListener的方法void selectItem(String name, int type)。
主Activity: MainActivity. Java

回调接口:OnSelectItemListener
[java] view plain copy
packagecom.lambdroid.callbacktest2;
publicinterfaceOnSelectItemListener {
voidselectItem(String name,inttype);
}
点击Button,弹出弹窗,显示三个Item
点击第二个Item,通过回调函数,来实现TextView内容的修改,以及弹出Toast
总结
Java回调情形涉及很多,本文属于接口的异步回调:当不知道何时会执行接口的回调函数,(通过接口回调来对获取到的资源的操作)。除此还有线程间的异步回调(子线程进行耗时操作,操作完毕通知主线程或将数据传给主线程处理),以及利用接口回调来实现线程间的数据通信等等(Android可以利用Handler来实现)。等下次再举例说明Java回调函数的其它情形。
