phonegap学习之CordovaWebView

最近学习phonegap，发现网上的中文文章都太旧了，现在选择最新的phonegap-2.9.1的学习过程记录下来，一方面整理过，能够加深理解，另一方面也可以帮助其他人学习，首先可以到phonegap官网下载phonegap-2.9.1

这是关于如何在app中嵌入cordova控件的学习，关于如何打包cordova-x.x.x.jar可以到官网下载phonegap2.9.1，在其中的\lib\android中根据README.md的提示打包即可。

1、把打包好的jar包导入android工程的libs目录下

2、在布局文件中的加入cordovawebview控件

<org.apache.cordova.CordovaWebView
    android:id="@+id/tutorialView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>
3、相关Activity必须改造为实现接口CordovaInterface，相关使用可参照/framework/src/org/apache/cordova/CordovaActivity.java，简要代码如下：

publicclassCordovaViewTestActivityextendsActivityimplementsCordovaInterface{
    CordovaWebView cwv;
    /* Called when the activity is first created. */
    @Override
    publicvoid onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        cwv =(CordovaWebView) findViewById(R.id.tutorialView);
        Config.init(this);
        cwv.loadUrl(Config.getStartUrl());
    }
4、app需要调用摄像头可以采用如下代码：

@Override
publicvoid setActivityResultCallback(CordovaPlugin plugin){
    this.activityResultCallback = plugin;
}
/**
 * Launch an activity for which you would like a result 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
 */
publicvoid 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 results
if(command !=null){
    this.keepRunning =false;
}


// Start activity
super.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").
 */
protectedvoid onActivityResult(int requestCode,int resultCode,Intent intent){
    super.onActivityResult(requestCode, resultCode, intent);
    CordovaPlugin callback =this.activityResultCallback;
    if(callback !=null){
        callback.onActivityResult(requestCode, resultCode, intent);
    }
}
5、记得要增加线程池，plugin需要跑在线程中:

@Override
publice ExecutorService getThreadPool(){
    return threadPool;
}
6、复制app的HTML 和JavaScript files 到 the Android 工程的 /assets/www 目录下。
7、从/framework/res/xml 复制config.xml 文件到工程的 /res/xml directory
