Question

我有一个包含两个片段的xml：webview和个人资料编辑器：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:orientation="vertical" >
<fragment
    android:id="@+id/editProfileFragmentOptions"
    android:name="com.tests.android.Profile"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<fragment
    android:id="@+id/webViewFragment"
    android:name="com.tests.android.MyWebView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
</LinearLayout>

名为“MyWebView”的片段是我的WebView，类MyWebView看起来像：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.generic_webview, 
            container, false);
    webView = (WebView)view.findViewById(R.id.webview);
    String summary = "<html><body>You scored <b>192</b> points.</body></html>";
    webView.loadData(summary, "text/html", null);
    return view;
}

当我点击显示该片段时，webview仍然一直空着......这是我用来显示片段的方法：

    buttonFAQ = (Button) this.findViewById(R.id.buttonFAQ);
    buttonFAQ.setOnClickListener(new OnClickListener()  {
        @Override
        public void onClick(View v) {
            ACTIVE_FRAGMENT = WEBVIEW_FRAGMENT;
            showFragment(WEBVIEW_FRAGMENT, true, ServerParams.WEBVIEW_FAQ);
        }
    });


private void showFragment(int fragmentIndex, boolean addToBackStack, ServerParams param) {
    FragmentManager fm = getSupportFragmentManager();
    FragmentTransaction transaction = fm.beginTransaction();
    for (int i = 0; i < fragments.length; i++) {
        if (i == fragmentIndex) {
            if(param != null){
                WebViewFragment webViewFragment = new WebViewFragment();
                Bundle bundle = new Bundle();
                bundle.putSerializable("serverParams", param);
                webViewFragment.setArguments(bundle);
                transaction.replace(fragments[i].getId(), webViewFragment);
            } else {                
                transaction.show(fragments[i]);
            }               
        } else {
            transaction.hide(fragments[i]);
        }
    }
    if (addToBackStack) {
        //transaction.addToBackStack("banana");
    }
    transaction.commit();
    displayButtons(false);
}

知道为什么我的网页视图为空/空白？
