android調(diào)用接口,Android調(diào)用網(wǎng)頁接口的例子

android 接口類調(diào)用問題

1、對應(yīng)一個接口即可,比如OnMsgChangeListener,代碼:

創(chuàng)新互聯(lián)-專業(yè)網(wǎng)站定制、快速模板網(wǎng)站建設(shè)、高性價比華池網(wǎng)站開發(fā)、企業(yè)建站全套包干低至880元,成熟完善的模板庫,直接使用。一站式華池網(wǎng)站制作公司更省心,省錢,快速模板網(wǎng)站建設(shè)找我們,業(yè)務(wù)覆蓋華池地區(qū)。費用合理售后完善,10多年實體公司更值得信賴。

public?interface?OnMsgChangeListener?{

public?void?doMsg(MsgBean?bean);

}

2、定義MsgBeanActivity處理MsgBean數(shù)據(jù)

3、定義MsgBean實體

4、在MsgBeanActivity定義setMsgChangeListener()方法,傳入的OnMsgChangeListener接口對象,如下代碼:

setMsgChangeListener(OnMsgChangeListener?onMsg)

5、重寫接口方法

android端怎么調(diào)用webservice接口

在Android平臺調(diào)用Web Service需要依賴于第三方類庫ksoap2,它是一個SOAP Web service客戶端開發(fā)包,主要用于資源受限制的Java環(huán)境如Applets或J2ME應(yīng)用程序(CLDC/ CDC/MIDP)。認真讀完對ksoap2的介紹你會發(fā)現(xiàn)并沒有提及它應(yīng)用于Android平臺開發(fā),沒錯,在Android平臺中我們并不會直接使用ksoap2,而是使用ksoap2 android。KSoap2 Android 是Android平臺上一個高效、輕量級的SOAP開發(fā)包,等同于Android平臺上的KSoap2的移植版本。

android怎么調(diào)用webservice接口

//WebService的命名空間

static final String namespace = "";

//服務(wù)器發(fā)布的url

static final String url = ;

final String methodName = "upload"; // 函數(shù)名

final int sessionID = "111111"; //sessionID

//創(chuàng)建HttpTransportSE對象,通過HttpTransportSE類的構(gòu)造方法可以指定WebService的url

HttpTransportSE transport = new HttpTransportSE(url);

transport.debug = true;

//指定WebService的命名空間和函數(shù)名

SoapObject soapObject = new SoapObject(namespace, methodName);

//設(shè)置調(diào)用方法參數(shù)的值

soapObject.addProperty("sessionID", sessionID); //sessionID

soapObject.addProperty("data", cds); //cds是需要傳遞的對象

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER10);

envelope.bodyOut = transport;

envelope.setOutputSoapObject(soapObject);

//使用call方法調(diào)用WebService方法

transport.call(null, envelope);

SoapObject sb = (SoapObject) envelope.bodyIn;

String xmlMessage = sb.toString(); // 獲取從服務(wù)器端返回的XML字符串

Android接口回調(diào)總結(jié),以及運用到彈窗PopWindow的Demo實現(xiàn)

最近項目中接觸到接口回調(diào),以及Android彈窗PopWindow組件的使用,現(xiàn)在利用學(xué)到的知識自己寫了一個簡單的Demo,練習(xí)下在Android下如何運用接口回調(diào),來實現(xiàn)彈窗PopWindow的功能。

1. 定義一個接口:OnSelectItemListener。定義一個方法 void selectItem(String name, int type),作為點擊彈窗的每個Item的回調(diào)接口。

2. 自定義彈窗類:MyPopupWindow,其布局文件為popup_window.xml。當(dāng)在MainActivity調(diào)用其構(gòu)造函數(shù)創(chuàng)建對象時,同時執(zhí)行initPopupWindow()函數(shù),給每個Item設(shè)置監(jiān)聽器,監(jiān)聽點擊Item時,回調(diào)接口函數(shù)selectItem("Pop Window A", POP_WINDOW_ITEM_1),該函數(shù)在MainActivity中實現(xiàn)。

3. 主Activity: MainActivity。其布局文件為一個Button和一個TextView。監(jiān)聽Button,每當(dāng)點擊則彈出PopWindow,呈現(xiàn)三個Item。調(diào)用MyPopupWindow類中的方法setOnSelectItemListener(OnSelectItemListener listener),傳入OnSelectItemListener 對象作為參數(shù),同時實現(xiàn)回調(diào)接口OnSelectItemListener的方法void selectItem(String name, int type)。

回調(diào)接口:OnSelectItemListener

[java] view plain copy

packagecom.lambdroid.callbacktest2;

publicinterfaceOnSelectItemListener?{

voidselectItem(String?name,inttype);

}

點擊Button,彈出彈窗,顯示三個Item

點擊第二個Item,通過回調(diào)函數(shù),來實現(xiàn)TextView內(nèi)容的修改,以及彈出Toast

總結(jié)

Java回調(diào)情形涉及很多,本文屬于接口的異步回調(diào):當(dāng)不知道何時會執(zhí)行接口的回調(diào)函數(shù),(通過接口回調(diào)來對獲取到的資源的操作)。除此還有線程間的異步回調(diào)(子線程進行耗時操作,操作完畢通知主線程或?qū)?shù)據(jù)傳給主線程處理),以及利用接口回調(diào)來實現(xiàn)線程間的數(shù)據(jù)通信等等(Android可以利用Handler來實現(xiàn))。等下次再舉例說明Java回調(diào)函數(shù)的其它情形。

Android APP調(diào)用第三方接口

首先要知道第三方App的activity的包名和啟動Activity是哪一個,然后可以通過包名直接調(diào)用起來。當(dāng)然Intent的時候要注意設(shè)置Flag是NewTask
