播放YouTube视频全屏的WebView崩溃

我想全屏播放YouTube上的视频，但我不能一个用户发出以下报告播放YouTube视频全屏的WebView崩溃

java.lang.NullPointerException

我的代码使用方法：

   web.getSettings().setJavaScriptEnabled(true); 
       web.getSettings().setLoadWithOverviewMode(true); 
       web.getSettings().setUseWideViewPort(true); 
       web.getSettings().setBuiltInZoomControls(true); 
       web.getSettings().setPluginState(WebSettings.PluginState.ON); 


       web.setWebChromeClient(new WebChromeClient(){ 
        @Override 
        public void onProgressChanged(WebView view, int newProgress) {   
         super.onProgressChanged(view, newProgress); 
         pgb.setProgress(newProgress); 
         }  

        @Override 
        public View getVideoLoadingProgressView() { 
        FrameLayout frameLayout = new FrameLayout(MainActivity.this);  
        frameLayout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,  
        LayoutParams.MATCH_PARENT)); 
        return frameLayout; 
        } 
       }); 

       web.loadUrl("http://www.youtube.com");

我只是想让我明白如何去做。

我认为问题是添加FrameLayout查看为什么不使用Actionbar Interminate Progress或尝试将一个进度栏放入xml布局并设置它的可见性一旦如果您认为您找到了解决方案，请将其作为答案发布，并在进度等于100时加载页面并将其隐藏。100 – Cjames 2014-09-01 02:24:28

谢谢！ :) – 2014-09-02 19:31:23

我使用actionbarcompat所以我下面的UI指导原则在这里

webview_layout.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 

    <WebView 
     android:id="@+id/webview" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"/> 

</RelativeLayout>

Main.class

public class Main extends ActionBarActivity{ 

    private WebView mWebView; 
    private String url; 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     supportRequestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS); 
     setContentView(R.layout.webview_layout); 

     url="http://example.com"; 

     getSupportActionBar(); 
     getSupportActionBar().setDisplayShowCustomEnabled(true); 
     getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
     getSupportActionBar().setHomeButtonEnabled(true); 
     getSupportActionBar().setTitle("TITLE HERE"); 

     mWebView = (WebView) findViewById(R.id.webview); 
     mWebView.getSettings().setJavaScriptEnabled(true); 
     mWebView.getSettings().setBuiltInZoomControls(true); 
     mWebView.getSettings().setAppCacheMaxSize(1024*1024*8); 
     mWebView.getSettings().setAppCachePath(""+this.getCacheDir()); 
     mWebView.getSettings().setAppCacheEnabled(true); 
     mWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);  
     mWebView.loadUrl(url); 
     mWebView.setWebViewClient(new MyWebViewClient()); 

     mWebView.setWebChromeClient(new WebChromeClient() { 
      public void onProgressChanged(WebView view, int progress) { 
       super.onProgressChanged(view, progress); 
       setSupportProgressBarIndeterminateVisibility((progress == 100)?false:true); 
      } 
      public void onReceivedTitle(WebView view, String title) { 
       super.onReceivedTitle(view, title); 
       CharSequence notavail = "Webpage not available"; 

      } 
     }); 
    } 

    public boolean onKeyDown(int keyCode, KeyEvent event) { 
     if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) { 
      mWebView.goBack(); 
      return true; 
     } 
     return super.onKeyDown(keyCode, event); 
    } 
    private class MyWebViewClient extends WebViewClient { 

     public boolean shouldOverrideUrlLoading(WebView view, String url) { 
      view.loadUrl(url); 
      return true; 
     } 
    } 

}

请自由地问他们什么这不太清楚。感谢希望它会帮助你，不要忘记投票

谢谢你使用actionbar的作品，但我想要更多的simle。就像打开全屏视频画廊的默认浏览器一样。顺便完美的工作。 – 2014-09-03 17:26:47
