在Android中使用Cordova 5.0構建自定義WebView

Question

我想用Cordova構建自定義WebView。爲此，我想覆蓋setWebChromeClient和setWebViewClient方法。但爲此，我需要一個SystemWebViewClient，它需要一個SystemWebViewEngine，目前我似乎無法得到它。我的繼承人的主要活動

public class MyActivity extends CordovaActivity implements CordovaInterface { 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     int threadSize = getResources().getInteger(R.integer.WIPThreadPoolSize); 

     // Initiate Thread pool 
     threadPool = new ThreadPoolExecutor(threadSize, threadSize, 10, TimeUnit.SECONDS, this.priorityQueue); 

     initApplicationInformationManager(); 

     // initialize global variables 
     GlobalApplicationVariables.initValues(this); 

     isActivityReady = false; 

     isActivityReady = false; 

     setContentView(R.layout.main_layout); 
     super.init(); 

    } 


    protected CordovaWebView makeWebView() { 

     SystemWebView webView = (SystemWebView) findViewById(R.id.customWebView); 
     SystemWebViewEngine engine = new SystemWebViewEngine(webView); 


     return new CordovaWebViewImpl(engine); 
    } 

    protected void createViews() { 
     appView.getView().requestFocusFromTouch(); 
    } 
} 

而且我的自定義網頁流量：

@SuppressLint("SetJavaScriptEnabled") 
public class CustomWebView extends SystemWebView { 

    private DebugServiceClient dbgClient; 

    public CustomWebView(Context context) { 
     super(context); 

     this.configureView(context); 
    } 

    public CustomWebView(Context context, AttributeSet attributeSet) { 
     super(context, attributeSet); 
     this.configureView(context); 
    } 

    /** 
    * Configure the web view. 
    * 
    * @param context 
    *   Context web view is running in. 
    */ 
    private void configureView(Context context) { 
     //Make the WebView visible and hide its scroll bars 
     setVisibility(View.VISIBLE); 
     setVerticalScrollBarEnabled(false); 
     setHorizontalScrollBarEnabled(false); 
     setOverScrollMode(OVER_SCROLL_NEVER); 

     WebSettings webSettings = getSettings(); 
     webSettings.setJavaScriptEnabled(true); 
     webSettings.setSupportZoom(false); 
     webSettings.setAppCacheEnabled(false); 
     webSettings.setDomStorageEnabled(true); 


     final MyActivity myActivity = (MyActivity) context; 


     setWebChromeClient(new SystemWebChromeClient(new SystemWebViewEngine(this)) { 

      public void onShowCustomView(View view, CustomViewCallback callback) { 
      /*Custom code*/ 
      } 

      public void onHideCustomView() { 

      /*Custom code*/ 

      } 
     }); 

     setWebViewClient(new SystemWebViewClient(new SystemWebViewEngine(this)) { 

      public boolean shouldOverrideUrlLoading(WebView webview, String url) { 
      /*Custom code*/  
      } 

      public void onReceivedError(WebView view, int errorCod, String description, String failingUrl) { 
       Log.e("Webview Error", errorCod + " - " + description + failingUrl); 
      } 
     }); 
    }   
} 

真的不能得到一個引擎，這樣的方法可以被覆蓋，所以我創建了一個在運行，但是這會產生一些錯誤。此外，我似乎無法訪問科爾多瓦插件管理器，因此我無法添加插件到web視圖。哪種做法最好？

我overrided SystemWebViewClient在MainActivity這種overrided方法

@Override 
protected CordovaWebViewEngine makeWebViewEngine() { 
    CordovaWebViewEngine ret = CordovaWebViewImpl.createEngine(this, preferences); 
    ((SystemWebView)ret.getView()).setWebViewClient(new SystemWebViewClient((SystemWebViewEngine)ret){ 
     @Override 
     public void onReceivedSslError(WebView view, final SslErrorHandler handler, SslError error) { 
      LOG.d(TAG, "ON RECEIVED SSL ERROR"); 
      super.onReceivedSslError(view, handler, error); 
     } 
    }); 
    return ret; 
}
