webview 无法输入，焦点乱跳的问题

如题，上代码： super.onCreate(savedInstanceState);
Log.i(TAG, "onCreate");

webtype = this.getIntent().getIntExtra(WebType,0);

ActivityUtil.ourInit(this);

setContentView(R.layout.common_layout_web);

TextView iTextview = (TextView)findViewById(R.id.xid_common_frame_title_text);
iTextview.setText(TiTles[webtype]);

webview = (WebView)findViewById(R.id.xid_common_webview);

ws = webview.getSettings();
        ws.setAllowFileAccess(true);//设置允许访问文件数据
        ws.setJavaScriptEnabled(true);//设置支持javascript脚本
        ws.setBuiltInZoomControls(true);//设置支持缩放
        ws.setSupportMultipleWindows(false);
        webview.setBackgroundColor(0x90FFFFFF);
        webview.requestFocus();
        
//        {
//         public boolean shouldOverrideUrlLoading(WebView view,String url){
//         //当有新连接时，使用当前的 WebView
//         Log.i(TAG,"shouldOverrideUrlLoading url ["+url+"]");
//         view.loadUrl(url);
//         view.requestFocusFromTouch();
//         return true;
//         }
//        
//         public void onPageFinished(WebView view, String url) 
//         {
//         Log.i(TAG,"onPageFinished url ["+url+"]");
//         WebActivity.this.stopProgressDialog();
//         webview.requestFocus();
//         super.onPageFinished(view, url);
//         }
//        
//         public void onPageStarted(WebView view, String url, Bitmap favicon)
//         {
//         Log.i(TAG,"onPageStart url ["+url+"]");
//         WebActivity.this.startProgressDialog("请稍候", "正在加载页面");
//         super.onPageStarted(view, url, favicon);
//         }
//        }
       // webview.setWebViewClient(new WebViewClient());        
        
        
if (savedInstanceState == null)
