android - Android Webview 视频播放

Question

我正在开发一个使用 webview 显示网页的应用程序，如果 url 是视频链接（youtube）或视频包含作为网页的一部分，我想播放视频。我尝试将 url 直接添加到 webview 但它甚至不播放 youtube 链接，我已经在 webview 中启用了插件和 javascript ..... 谁能帮我解决这个问题，

试试这种方式：

private WebView m_wvMain;  
private Button m_btnPlayVideo;  
private ProgressDialog m_progressLoading;  
private String m_videoUrl;  
private Context m_context;  
@Override
protected void onCreate(Bundle p_savedInstanceState) {
    super.onCreate(p_savedInstanceState);
    setContentView(R.layout.flashcontentplayer);
    m_context = FlashContentPlayer.this;
    m_wvMain = (WebView) findViewById(R.id.fcpwvMain);
    m_btnPlayVideo = (Button) findViewById(R.id.fcpbtnPlayVideo);
    m_wvMain.getSettings().setJavaScriptEnabled(true);
    m_wvMain.getSettings().setAllowFileAccess(true);
    m_wvMain.getSettings().setPluginsEnabled(true);
    m_wvMain.getSettings().setPluginState(WebSettings.PluginState.ON);
    if (getIntent().hasExtra("video_url")) {
        m_videoUrl = getIntent().getExtras().getString(
                AppConstants.VIDEO_URL);
    }
    m_wvMain.setWebViewClient(new VideoWebViewClient());
    m_progressLoading = new ProgressDialog(m_context);
    m_progressLoading.setTitle(getString(R.string.app_name));
    m_progressLoading.setMessage("Loading ...");
    m_btnPlayVideo.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View p_v) {
            if (m_videoUrl == null) {

if (webView == null) {
            webView = (WebView) findViewById(R.id.web_view);
            webView.getSettings().setJavaScriptEnabled(true);
            webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(false);
            webView.getSettings().setPluginsEnabled(true);
            webView.getSettings().setSupportMultipleWindows(false);
            webView.getSettings().setSupportZoom(false);
            webView.setVerticalScrollBarEnabled(false);
            webView.setHorizontalScrollBarEnabled(false);
            webView.setWebChromeClient(new WebChromeClient());

        }

webView.setWebViewClient(new WebViewClient() {
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {

                    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
