片段的WebView Java脚本功能无法正常工作 [英] Fragment webview java script function is not working

问题描述

我已经动态创建操作栏和标签。我有喜欢跌破code标签片段定义一个类。

I have dynamically created the action bar and tabs. I have define a class for tab fragments like the below code.

public static class TabFragmentClass extends Fragment
{   
 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub
       try
       {
           linearLayout=new LinearLayout(sActiveContext);
           linearLayout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT)); 
           linearLayout.setOrientation(LinearLayout.VERTICAL);
           CustomWebView webview=new CustomWebView(sActiveContext);
           FrameLayout layout=webview.createwebview();
           for (int i = 0; i < arrayList.size(); i++) {
               if(sActionBar.getSelectedTab().getPosition()==i)
               {
                   webview.initwebview(arrayList.get(i));
                   mWebViewList.add(i, webview);
                   break;
               }
           }
           linearLayout.addView(layout);
           linearLayout.setId(sActionBar.getSelectedTab().getPosition());
           return linearLayout;
        }
        catch(Exception error)
        {
            System.out.println(error.getMessage());
            return null;
        }

 }
   }

网址是具有自己的本地Java方法调用本地HTML文件。如果我选择的动作栏选项卡的第一次，这是做工精细。这是原生的Java方法正确调用和回调是成功的。如果我访问的标签第二次，该片段只显示，不重新创建选项卡的内容。 我需要的标签内容每次不创建功能。但我面临的不是定义的本地方法的错误的问题。这是本机方法不叫在所有。如何解决这个问题？

The url is the local html file having their own native java method calls. If I am select the action bar tab first time, this is working fine. That is native java method is correctly called and callback is success. If I am visiting the tab second time, the fragment is only shown, tabs content is not re-created. I need the functionality of tab content not created each time. But I am facing the issue of native method not defined error. That is the native method is not called at all. How can I fix the issue?

更​​改您的片段此，

public static class TabFragmentClass extends Fragment
{   
   private static CustomWebView webview=null;
   private static boolean isInitialized=false;
 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    // TODO Auto-generated method stub
       try
       {
           linearLayout=new LinearLayout(sActiveContext);
           linearLayout.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT)); 
           linearLayout.setOrientation(LinearLayout.VERTICAL);
           webview=new CustomWebView(sActiveContext);
           FrameLayout layout=webview.createwebview();
           onLoadWebview();
           linearLayout.addView(layout);
           linearLayout.setId(sActionBar.getSelectedTab().getPosition());
           return linearLayout;
        }
        catch(Exception error)
        {
            System.out.println(error.getMessage());
            return null;
        }

 }
@Override
public void onActivityCreated()
{
super.onActivityCreated();
isInitialized=true;
}
@Override
public void onResume()
{
if(isInitialized)
    onLoadWebView();
}
public void onLoadWebview()
{
for (int i = 0; i < arrayList.size(); i++) {
               if(sActionBar.getSelectedTab().getPosition()==i)
               {
                   webview.initwebview(arrayList.get(i));
                   mWebViewList.add(i, webview);
                   break;
               }
           }
}
   }
