推荐答案

WebView webview1 = (WebView) findViewById(R.id.webview1);
webview.getSettings().setJavaScriptEnabled(true); 
String filename = "http://www.adobe.com/devnet/acrobat/pdfs/pdf_open_parameters.pdf";
String filename1 = "http://www.adobe.com/devnet/acrobat/pdfs/pdf_open_parameters1.pdf";

在

  ListView lt = (ListView) findViewById(R.id.listview);

            lt.setOnItemClickListener(new OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                        long arg3) {
                    // TODO Auto-generated method stub

                    if (arg2 == 1) {
                          webview.loadUrl("http://docs.google.com/gview?embedded=true&url=" + filename);
                    }

                    if (arg2 == 2) {
    webview.loadUrl("http://docs.google.com/gview?embedded=true&url=" + filename1);
                    }

                }
            });
