我有这个代码可以显示WebView并使用它:
WebView webview = null;
@Override
public void onCreate(Bundle savedInstanceState)
{
//setTheme(R.style.Theme_Sherlock_Light);
super.onCreate(savedInstanceState);
//setContentView(R.layout.podcasts);
webview = new WebView(this);
webview.getSettings().setAppCacheEnabled(false);
webview.getSettings().setJavaScriptEnabled(true);
webview.setInitialScale(1);
webview.getSettings().setPluginState(PluginState.ON);
webview.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
//webSettings.setBuiltInZoomControls(true);
WebSettings webSettings = webview.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setBuiltInZoomControls(true);
//webSettings.getMediaPlaybackRequiresUserGesture();
webSettings.setAllowContentAccess(true);
webSettings.setEnableSmoothTransition(true);
webSettings.setLoadsImagesAutomatically(true);
webSettings.setLoadWithOverviewMode(true);
webSettings.setSupportZoom(true);
webSettings.setUseWideViewPort(true);
setContentView(webview);
webview.loadUrl("url_to_go_to");
但是当我尝试使用此代码指向YouTube频道时,它只显示一个空白屏幕。 知道为什么会这样吗?
谢谢!

要显示HTML5视频,您需要在WebView中启用以下内容:
WebView view;
... //initialize WebView
WebSettings webViewSettings = view.getSettings();
view.setWebChromeClient(new WebChromeClient(){}); //just added this
webViewSettings.setDomStorageEnabled(true);
webViewSettings.setAppCacheEnabled(true);
webViewSettings.setAppCachePath(getApplicationContext().getFilesDir().getAbsolutePath() + "/cache");
webViewSettings.setDatabaseEnabled(true);
webViewSettings.setDatabasePath(getApplicationContext().getFilesDir().getAbsolutePath() + "/databases");
您还需要将android:hardwareAccelerated="true"
放入AndroidManifest中。否则,像YouTube视频这样的HTML5内容将无效。
