Youtube内部的webview在android应用程序

Youtube inside webview in android application

在阅读了不同的例子后，我几乎达到了想要的结果

代码:

WebView myWebView = (WebView)findViewById(R.id.webview);
String strHTMLTags = "<iframe width='"100%'" height='"100%'" src='"http://www.youtube.com/embed/MwdUyxyRwc8?autoplay=1'" frameborder='"0'" allowfullscreen='"1'" mozallowfullscreen='"1'" webkitallowfullscreen='"1'"></iframe>";
myWebView.setWebViewClient(new WebViewClient());
myWebView.setWebChromeClient(new WebChromeClient() {});     
myWebView.getSettings().setJavaScriptEnabled(true);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.loadData(strHTMLTags, "text/html", "utf-8");

这将使代码工作得很好，除了自动启动。

如果我在"loadData"之前添加以下代码:

webSettings.setUserAgentString("Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/534.36 (KHTML, like Gecko) Chrome/13.0.766.0 Safari/534.36");
        webSettings.setPluginState(WebSettings.PluginState.ON);
        webSettings.setAllowFileAccess(true);

此代码与自动启动工作，但分辨率不正确，视频不像他应该的那样。

setUserAgentString到底做什么，我怎么能让他与autostart工作。

我再试一试:

public void onPageFinished(WebView view, String url) {
    int cursorXPos = (int) (view.getX() + view.getWidth()/2);
    int cursorYPos = (int) (view.getX() + view.getHeight()/2);
    int cursorXPos = CENTER_OF_SCREEN_X_POS;
    int cursorYPos = CENTER_OF_SCREEN_Y_POS;
    mInstrumentation.sendPointerSync(MotionEvent.obtain(SystemClock.uptimeMillis(),
            SystemClock.uptimeMillis(),MotionEvent.ACTION_DOWN, cursorXPos,
            cursorYPos, 0));
    mInstrumentation.sendPointerSync(MotionEvent.obtain(SystemClock.uptimeMillis(),
            SystemClock.uptimeMillis(),MotionEvent.ACTION_UP, cursorXPos,
            cursorYPos, 0));
}

});
