Question

我无法看到我使用下面的新代码打开此网页视图。我让它使用注释掉的代码。我需要获取新代码来加载Web视图。我正在使用此示例代码。我怎样才能解决它没有打开页面的问题？ The Sample code

@Override   
 protected void onActivityResult(int requestCode, int resultCode,    
                                    Intent intent) {    
  if(requestCode==FILECHOOSER_RESULTCODE)    
  {    
   if (null == mUploadMessage) return;    
           Uri result = intent == null || resultCode != RESULT_OK ? null   
                   : intent.getData();    
           mUploadMessage.onReceiveValue(result);    
           mUploadMessage = null;    

}    
}    

@Override
public boolean onOptionsItemSelected(MenuItem item) {    
    // Handle item selection    
    switch (item.getItemId()) {        
    case R.id.register:            
        //mWebView2 = (WebView) findViewById(R.id.webview);    
       // mWebView2.getSettings().setJavaScriptEnabled(true);    
       // mWebView2.loadUrl("http://www.Mysite.com/AndroidAddMember.aspx");
        //mWebView2.setWebViewClient(new HelloWebViewClient());   

        wv = new WebView(this);  
        wv.setWebViewClient(new WebViewClient());   
        wv.getSettings().setJavaScriptEnabled(true); 

        wv.loadUrl("http://www.Mysite.com/AndroidAddMember.aspx"); 

          wv.setWebViewClient(new WebViewClient());    
          wv.setWebChromeClient(new WebChromeClient()    
          {    
                 //The undocumented magic method override    
                 //Eclipse will swear at you if you try to put @Override here    

              public void openFileChooser(ValueCallback<Uri> uploadMsg) {    

                  mUploadMessage = uploadMsg;    
                  Intent i = new Intent(Intent.ACTION_GET_CONTENT);    
                  i.addCategory(Intent.CATEGORY_OPENABLE);    
                  i.setType("image/*");    
                  BangMeorNot.this.startActivityForResult(Intent.createChooser(i,"File Chooser"), FILECHOOSER_RESULTCODE);    

                 }    
        });    
            setContentView(wv);    

        return true;

也许是因为你正在初始化同一个webview两次，而在第二次，你没有在它上面调用loadUrl（）方法。

尝试在第二次初始化后设置url。问题是您要将内容视图设置为webview，但webview没有要加载的URL。

使用webchromeclient加载webview
