如何通過webview調用javascript函數？

Question

我有兩個消息，當調用invokeScriptMethod（「showPoll（」+ Device.PollID +「）;」）; 並且不起作用！

在logcat的消息 1-防火牆不爲空 2-歐拉：isUrlBlocked =假

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_poll);  
    Device.webViewShowPoll = (WebView) findViewById(R.id.webViewShowPoll);  
    Device.webViewShowPoll.getSettings().setJavaScriptEnabled(true);   
    Device.webViewShowPoll.getSettings().setPluginsEnabled(true);   
    Device.webViewShowPoll.getSettings().setJavaScriptCanOpenWindowsAutomatically(true); 
    Device.webViewShowPoll.getSettings().setAllowFileAccess(true); 
    Device.webViewShowPoll.addJavascriptInterface(appconnector, "appConnector"); 

    try 
    { 
     Device.webViewShowPoll.loadDataWithBaseURL("file:///android_asset/", 
       Utility.convertStreamToString(getAssets().open("application.html", 
         AssetManager.ACCESS_BUFFER)), "text/html", "utf-8","");   
    } 
    catch (IOException e) 
    { 
     Log.e(getString(R.string.app_name), e.getMessage()); 
    } 
} 

public static void invokeScriptMethod(String method) { 

    Device.webViewShowPoll.loadUrl("javascript:" + method); 
} 

public static void invokeScript(String script) { 
    Device.webViewShowPoll.loadUrl(script); 
} 

public void bt_click(View v) 
{ 
    invokeScriptMethod("showPoll(" + Device.PollID + ");"); 
}

和的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.omid.epoll.mobile" 
android:versionCode="1" 
android:versionName="1.0" > 
<uses-sdk android:minSdkVersion="8" 
android:targetSdkVersion="16" /> 

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

Answer 1

可能這行代碼有助於： webView.getSettings().setPluginState(PluginState.ON);
