我正在制作一个用于在电视机上显示 youtube.com/tv 的应用程序。它具有简单而漂亮的布局，并且还具有一些不错的功能，例如通过智能手机配对和控制它。所以.. 我使用 webview 来获取网址：youtube.com/tv

一切正常，除了我希望它在选择 vid 时自动全屏显示。

通常我已经找到了我所有的答案，（在这里）但是这个很难。

我希望一切都发生在 webview 中。那应该可以吗？还是我需要开始一个新的意图，或者创建一个新类 videoview.java 来调用 eks。视频视图.xml？对此真的不确定.. 我问的原因是，当一个视频开始时，youtube.com/tv 会像播放列表一样自动播放下一个，希望保持这种状态。

我在http://developer.android.com/reference/android/webkit/WebChromeClient.html#onShowCustomView(android.view.View , android.webkit.WebChromeClient.CustomViewCallback)找到了一些关于 HTML5 全屏的文档，但是仍然很困惑。这是要走的路吗？使用：

public void onShowCustomView(View view, WebChromeClient.CustomViewCallback callback)

和：

public void onHideCustomView ()

这是我的主要 TV.java 直到现在。请温柔一点，因为我对这些东西很陌生。

@SuppressLint("SetJavaScriptEnabled")
public class Tv extends Activity
{
    WebView web;

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        //Transparent actionBar Only option menu available...
        requestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
        ActionBar actionBar = getActionBar();
        actionBar.setBackgroundDrawable(null);
        setDisplayShowHomeEnabled(false);
        setTitleShowHomeEnabled();
        getActionBar().setDisplayShowHomeEnabled(false);
        getActionBar().setDisplayShowTitleEnabled(false);

        super.onCreate(savedInstanceState);
        setContentView(R.layout.webview);

        // webview id
        web = (WebView) findViewById(R.id.webview);
        //webchromeclient
        web.setWebChromeClient(new WebChromeClient());
        //hide search bar
        web.setWebViewClient(new myWebClient());
        //Enable javascript
        web.getSettings().setJavaScriptEnabled(true);
        web.getSettings().setPluginState(PluginState.ON);
        //Scale video controls
        web.setInitialScale(150);
        // Test

        //web.getSettings().setLoadWithOverviewMode(true);
        //web.getSettings().setUseWideViewPort(true);
        //web.setVerticalScrollbarOverlay(true);

        //Load url

    public void onShowCustomView(View view, WebChromeClient.CustomViewCallback callback)
