我在我的活动实施的WebView，因为我已经给了允许

I've implemented a WebView in my Activity, for that I've given the permission

<uses-permission android:name="android.permission.INTERNET"/>

本code：

with this code:

    WebView mWebView;
    mWebView = (WebView) findViewById(R.id.ueber_webview);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.getSettings().setPluginsEnabled(true);
    mWebView.loadUrl("file:///android_asset/MyTestPage.htm");

在 HTML 页是加载 *的以及的*，也都是显示在视频，其边界和典型的YouTube的播放键式视频的中心。但是，当我的 preSS 的，视频的不 *的负荷的*。

The html page is loading *well*, also the are displayed the video with its border and the typical Youtube-Play-Button in the center of the video. But when I press it, the video doesn't *load*.

这是HTM内容：

    <div id="playerFrame">
<iframe src="http://www.youtube.com/embed/MyURL" //have to hide the url, ends with something like "...j4Fs?rel=0"
frameborder="0" allowfullscreen id="playerPlaceHolder"></iframe>
</div>

因为这是正确显示CSS的内容必须是正确的，这不应该成为问题。

The css content must be correct cause it's displayed correctly, that shouldn't be the problem.

任何帮助吗？

推荐答案

现在它的工作原理，借助一些东西的组合：

Now it works, with a combination of some things:

public class Videos extends Activity {

private WebView mWebView;
private String extra;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.videos_layout);       

    extra = getIntent().getStringExtra("VideosId");        
    mWebView = (WebView) findViewById(R.id.videos_webview); 
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.getSettings().setPluginsEnabled(true);

    final Activity activity = this;
    mWebView.setWebChromeClient(new WebChromeClient() {
      public void onProgressChanged(WebView view, int progress) {
        // Activities and WebViews measure progress with different scales.
        // The progress meter will automatically disappear when we reach 100%
        activity.setProgress(progress * 1000);
      }
    });

    mWebView.setWebViewClient(new MyOwnWebViewClient());   


    mWebView.loadUrl("file:///android_asset/Videos/"+extra+".htm");     
    mWebView.setWebViewClient(new MyOwnWebViewClient());      
}

//Ermöglicht das Zurücknavigieren im Browser mittels Back-Button
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
        mWebView.goBack();
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

和在清单中这些条目：

    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>

<application android:icon="@drawable/icon" android:label="@string/app_name" android:hardwareAccelerated = "true">

但我不知道，哪一个都至少有必要的。此外，它不可能跳过的视频部分，我要的看它在一个回合。任何人都知道解决的办法？

But I don't know, which one are at least necessary. Further, it's not possible to skip parts of the video, I have to watch it in one turn. Anyone knows a solution?

和 MyOwnWebViewClient

import android.webkit.WebView;
import android.webkit.WebViewClient;
//Enables the possibility for the User to navigate in the WebView and prevents,
//that the Standard-Browser is invoked

public class MyOwnWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }

}
