Fragment里使用CordovaWebView

因为CordovaWebView 默认的初始化里判断了Content是不是继承CordovaInterface，如果直接使用Fragment继承CordovaInterface，CordovaInterface有个抽象方法getActicity （）和Fragment的相冲突了，并且Fragment的这个同名方法还是final的，无法覆盖。

查看CordovaWebView的源码，它是这样实现的。

public CordovaWebView(Context context, AttributeSet attrs, int defStyle, boolean privateBrowsing) {        super(context, attrs, defStyle, privateBrowsing);        if (CordovaInterface.class.isInstance(context))        {            this.cordova = (CordovaInterface) context;        }        else        {            Log.d(TAG, "Your activity must implement CordovaInterface to work");        }        this.setWebChromeClient(new CordovaChromeClient(this.cordova));        this.initWebViewClient(this.cordova);        this.loadConfiguration();        this.setup();    }

所以只要让CordovaWebView的Content是实现CordovaInterface的接口就可以了。

实现一个类继承接口CordovaInterface：

private class CordovaContext extends ContextWrapper implements CordovaInterface {        Activity activity;        protected final ExecutorService threadPool = Executors.newCachedThreadPool();        public CordovaContext(Activity activity) {            super(activity.getBaseContext());            this.activity = activity;        }        public void startActivityForResult(CordovaPlugin command, Intent intent, int requestCode) {            //activity.startActivityForResult(command, intent, requestCode);        }        public void setActivityResultCallback(CordovaPlugin plugin) {            //activity.setActivityResultCallback(plugin);        }        public Activity getActivity() {            return activity;        }        public Object onMessage(String id, Object data) {            return null;        }        public ExecutorService getThreadPool() {            return threadPool;        }    }

然后在Fragment的onCreateView方法里，更改默认的LayoutInflater inflater的content；

inflater ＝ cloneInContext(new CordovaContext(mActivity)；

这样就可以实现Fragment里正常使用CordovaWebView。
