YouTube視頻不能在WebView中播放

YouTube視頻不能在WebView中播放。YouTube視頻不能在WebView中播放

它是我的第一個應用程序，我想做一個web視圖。當我打開YouTube時，視頻不能播放，正在加載但不能播放。正在加載。非常感謝您的幫助。

的Java：

public class MainActivity extends Activity { 

    private WebView mWebView; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     mWebView = (WebView) findViewById(R.id.webview); 
     mWebView.getSettings().setJavaScriptEnabled(true); 
     mWebView.loadUrl("http://www.google.com"); 
     mWebView.setWebViewClient(new HelloWebViewClient()); 

    } 

private class HelloWebViewClient extends WebViewClient { 
     @Override 
     public boolean shouldOverrideUrlLoading(WebView webview, String url) 
     { 
     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); 

    } }

XML：

<?xml version="1.0" encoding="utf-8"?> 
<WebView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/webview" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
/>

好像的play youtube video in WebView重複和YouTube Video not playing in WebView - Android

爲了使它通過的WebView工作，我用了以下兩個步驟（4.2版本。 2/Nexus 4）：

在shouldOverrideUrlLoading我加webview.setWebChromeClient(new WebChromeClient());
在AndroidManifest.xml爲activity標籤我加android:hardwareAccelerated="true"

AndroidManifest.xml中還應該包含Internet權限。

儘管通過WebView播放視頻的確切步驟可以針對設備和Android版本，但也可以使用其他WebView替代方法，例如VideoView或使用Youtube Android Player API。

EDIT1

至於暫停和全屏，這其實是我在開頭提到的第二個鏈接。爲了更容易，我發佈了在我的Nexus上工作的代碼。

在activity_main.xml中

<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>

在MainActivity類別：

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); 

} 
}

但它沒有工作。 – omer341

@ omer341你試圖在哪個Android版本上運行它或模擬它？你有什麼嘗試？添加了'webview.setWebChromeClient（new WebChromeClient（）{}）;'和硬件加速標記對您的情況沒有用處？ –

我試圖在我的平板電腦上運行它在Android 4.1.2版本上。 – omer341

添加webchrome客戶解決了我已經看到了這個問題，

web = (WebView) vi.findViewById(R.id.offer_webView1); 

     web.loadUrl(getResources().getString(R.string.videolink)); 

     web.getSettings().setJavaScriptEnabled(true); 
     // web.getSettings().setDomStorageEnabled(true); 

     web.getSettings().setAllowContentAccess(true); 
     WebSettings webSettings = web.getSettings(); 
     webSettings.setPluginState(WebSettings.PluginState.ON); 
     webSettings.setUseWideViewPort(true); 
     webSettings.setLoadWithOverviewMode(true); 
     web.canGoBack(); 
     web.setWebChromeClient(new WebChromeClient() {});
