webview没有在android的片段内加载url

Question

我是 Fragment 的新手。我正在 Fragment 内的 webview 中加载 url，但它没有加载。在模拟器网页中可能会暂时关闭消息。在 samsung Galaxy 选项卡设备中出现空白谁能告诉什么是问题如何解决

import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;

public class WebViewFragment1 extends Fragment {
    WebView loadWeb; 

    @Override       
    public void onCreate(Bundle savedInstanceState) 
    {      
        super.onCreate(savedInstanceState);            
        // Tell the framework to try to keep this fragment around           
        // during a configuration change.           
        setRetainInstance(true);          
 // Start up the worker thread.          

    }
    public View onCreateView(final LayoutInflater inflater, final ViewGroup container, final Bundle savedInstanceState) { 
        ViewGroup layout = (ViewGroup) inflater.inflate(R.layout.gcmweb, container, false); 
        loadWeb=(WebView)layout.findViewById(R.id.loadWeb); 
        /*String url = "http://unstructure.org/unstruc/unstruc.php?i="
            + "sample test".replaceAll(" ", "-");*/
        String url="http://www.google.com/";
loadWeb.loadUrl(url);       
        return layout; 
        }

}

这里我在activity中动态添加

FragmentTransaction ft = fm.beginTransaction();  
         Fragment fragReplace=new WebViewFragment1();
            //fm.beginTransaction(); 
            ft.add(R.id.replace_frag_container,fragReplace);    
            ft.addToBackStack(null);
            ft.commit();

谢谢

Answer 1

对于使用片段，您应该扩展活动并具有片段布局，反之亦然。查看this link这是一个非常适合初学者的教程

Answer 2

    public class DetailsFragment extends Fragment {
  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
                            Bundle savedInstanceState) {
    return(inflater.inflate(R.layout.details_fragment, container, false));
  }

  public void loadUrl(String url) {
    ((WebView)(getView().findViewById(R.id.browser))).loadUrl(url);
  }
}

这对我有用，你可以试试这个吗..
