YouTube-Video spielt zwar nicht in WebView

Scheint duplizieren von spielen Sie youtube-video in WebView und YouTube Videos spielen nicht in der WebView - Android

Machen, damit es funktioniert über die Webansicht verwendet habe ich die folgenden zwei Schritte (version 4.2.2/Nexus 4):

1. Auf shouldOverrideUrlLoading ich Hinzugefügt webview.setWebChromeClient(new WebChromeClient());

2. In AndroidManifest.xml für activity tag fügte ich android:hardwareAccelerated="true"

AndroidManifest.xml sollte auch enthalten Internet-Berechtigung.

Während die genauen Schritte bei der Wiedergabe von Videos via WebView spezifischen Gerät und Android-version, es gibt auch andere alternativen, um die WebView, wie VideoView oder mit Youtube Android Player API.

EDIT1

Als pause und Vollbild, das ist eigentlich einen zweiten link, den ich zu Beginn erwähnt. Um es einfacher zu machen, ich bin Entsendung code funktionierte auf meinem Nexus.

1. In activity_main.xml

   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
       xmlns:tools="http://schemas.android.com/tools"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:paddingBottom="@dimen/activity_vertical_margin"
       android:paddingLeft="@dimen/activity_horizontal_margin"
       android:paddingRight="@dimen/activity_horizontal_margin"
       android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >
   
   <FrameLayout
             android:id="@+id/fullscreen_custom_content"
             android:layout_width="match_parent"
             android:layout_height="match_parent"
             android:background="#FF000000"/>
   
   <LinearLayout 
             android:id="@+id/linearlayout"
             android:layout_width="fill_parent" 
             android:layout_height="fill_parent"> 
   
        <WebView
              android:id="@+id/webView"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent" />
   
   </LinearLayout>
   </RelativeLayout>

2. In der MainActivity-Klasse:

   public class MainActivity extends Activity {
   
   private WebView mWebView;  
   private LinearLayout mContentView;
   private FrameLayout mCustomViewContainer;
   private WebChromeClient.CustomViewCallback mCustomViewCallback;
   FrameLayout.LayoutParams COVER_SCREEN_GRAVITY_CENTER = new FrameLayout.LayoutParams(
           ViewGroup.LayoutParams.WRAP_CONTENT,
           ViewGroup.LayoutParams.WRAP_CONTENT, Gravity.CENTER);
   
   @Override
   protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
   
       mContentView = (LinearLayout) findViewById(R.id.linearlayout);
       mWebView = (WebView) findViewById(R.id.webView);
       mCustomViewContainer = (FrameLayout) findViewById(R.id.fullscreen_custom_content);
   
       WebSettings webSettings = mWebView.getSettings();
       webSettings.setPluginState(WebSettings.PluginState.ON);
       webSettings.setJavaScriptEnabled(true);
       webSettings.setUseWideViewPort(true);
       webSettings.setLoadWithOverviewMode(true);
   
       mWebView.loadUrl("http://www.google.com");
       mWebView.setWebViewClient(new HelloWebViewClient());
   
   }
   
   @Override
   public boolean onCreateOptionsMenu(Menu menu) {
       //Inflate the menu; this adds items to the action bar if it is present.
       getMenuInflater().inflate(R.menu.main, menu);
       return true;
   }
   
   
   
   private class HelloWebViewClient extends WebViewClient  {
       @Override
       public boolean shouldOverrideUrlLoading(WebView webview, String url)
       {
           webview.setWebChromeClient(new WebChromeClient() {
   
               private View mCustomView;
   
                @Override
               public void onShowCustomView(View view, WebChromeClient.CustomViewCallback callback)
               {
                   //if a view already exists then immediately terminate the new one
                   if (mCustomView != null)
                   {
                       callback.onCustomViewHidden();
                       return;
                   }
   
                   //Add the custom view to its container.
                   mCustomViewContainer.addView(view, COVER_SCREEN_GRAVITY_CENTER);
                   mCustomView = view;
                   mCustomViewCallback = callback;
   
                   //hide main browser view
                   mContentView.setVisibility(View.GONE);
   
                   //Finally show the custom view container.
                   mCustomViewContainer.setVisibility(View.VISIBLE);
                   mCustomViewContainer.bringToFront();
               }
   
           }); 
   
         webview.loadUrl(url);
   
         return true;
       }
   }
   
   @Override
   public boolean onKeyDown(int keyCode, KeyEvent event)
   {
       if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack())
       {
           mWebView.goBack();
           return true;
       }
       return super.onKeyDown(keyCode, event);
   
   } 
   }
