Android原生软件里嵌入一个基于cordova的网页页面（webview）

本篇文章翻译自cordova官网：其地址为：http://cordova.apache.org/docs/en/3.6.0/guide/platforms/android/webview.htmlAndroid webview这篇文章指导用户在Android原生软件里嵌入一个基于cordova的网页页面（webview）。这些部件是怎样在互相之间交流数据请查看：Application Plugins如果你不熟悉安卓开发，那你就需要先学习Android开发环境搭建，使用一下网址学习：http://cordova.apache.org/docs/en/latest/guide/platforms/android/index.html至少安装Android SDK，在你开发网页嵌入应用之前。自从Cordova 1.9开始。安卓平台依赖组件“CordovaWebView”。1． 跟随这些说明，确保你安装了最新的cordova版本。，从cordova.apache.org下载并解压。2． 切换到解压出来文件夹的/framework目录，然后运行ant jar。就会创建出一个叫Cordova.jar的文件。文件被放置在目录/framework/cordova-x.x.x.jar。3． 复制这个.jar文件到Android项目的/libs目录4． 然后编辑Android项目目录的/res/xml/main.xml文件。加入一下文件：

<org.apache.cordova.CordovaWebView
android:id="@+id/tutorialView"
android:layout_width="match_parent"
android:layout_height="match_parent" />

5． 修改需要放置网页的activity的类为以下内容，即实现接口CordovaInterface。并实现包括的方法。当然一下的文件其实在这个目录找到：

/framework/src/org/apache/cordova/CordovaActivity.java

以下代码展示了一个依靠接口的基本应用。展示了怎样通过ID调用之前创建的界面文件里的控件。代码如下：

CordovaInterface {
CordovaWebView cwv;
/* Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
cwv = (CordovaWebView) findViewById(R.id.tutorialView);
Config.init(this);
cwv.loadUrl(Config.getStartUrl());
}

6．

如果当前网页页面需要调用摄像头，请实现一下部分。

@Overridepublic void setActivityResultCallback(CordovaPlugin plugin) {this.activityResultCallback = plugin;}/*** Launch an activity for which you would like a res4000ult when it finished. When this activity exits,* your onActivityResult() method is called.** @param command The command object* @param intent The intent to start* @param requestCode The request code that is passed to callback to identify the activity*/public void startActivityForResult(CordovaPlugin command, Intent intent, int requestCode) {this.activityResultCallback = command;this.activityResultKeepRunning = this.keepRunning;// If multitasking turned on, then disable it for activities that return resultsif (command != null) {this.keepRunning = false;}// Start activitysuper.startActivityForResult(intent, requestCode);}@Override/*** Called when an activity you launched exits, giving you the requestCode you started it with,* the resultCode it returned, and any additional data from it.** @param requestCode The request code originally supplied to startActivityForResult(),* allowing you to identify who this result came from.* @param resultCode The integer result code returned by the child activity through its setResult().* @param data An Intent, which can return result data to the caller (various data can be attached to Intent "extras").*/protected void onActivityResult(int requestCode, int resultCode, Intent intent) {super.onActivityResult(requestCode, resultCode, intent);CordovaPlugin callback = this.activityResultCallback;if (callback != null) {callback.onActivityResult(requestCode, resultCode, intent);}}

7．

最终，要记得增加线程池。负责插件不知道该在那个线程里运行。

@Override

public ExecutorService getThreadPool() {

    return threadPool;

}

8．

复制网页的html页面，js文件等到安卓项目的/assets/www文件夹下

9．

从下载并减压下来的文件夹里的/framework/res/xml里复制config.xml文件到安卓项目目录的/res/xml目录下。
