Iam無法顯示PPT Infact我想要顯示的不僅是PPT，而且doc/ppt/pdf/xls文件在視圖中.....在Android中

Question

final Uri uri = Uri.fromFile(file); 

final Intent intent = new Intent(Intent.ACTION_VIEW); 

intent.setDataAndType(uri, "application/vnd.ms-powerpoint"); 

PackageManager pm = getPackageManager(); 

List<ResolveInfo> list = pm.queryIntentActivities(intent, 0); 

if(list.size() > 0) 

startActivity(context, intent);` 

當你看到上面的代碼是在我的android平板電腦上顯示MS PPT。

現在我的代碼程序如下。

1.我將從URL下載一個ppt並將它存儲在SD卡中。

2.然後我想在視圖中顯示ppt，我認爲這恰恰適合於此。

所以蔭無法顯示PPT INFACT我想在一個視圖中顯示的不僅百分點，而且DOC/PPT/PDF/XLS文件.....

那麼該怎麼辦呢??? ??

In ICS You have default polaris application you can use 


     else if (TEXT == type) { 
        File targetFile = new File(path); 
        Uri targetUri = Uri.fromFile(targetFile); 
        Intent intent = new Intent(Intent.ACTION_VIEW); 
        intent.setDataAndType(targetUri, "text/plain"); 
        startActivityForResult(intent, TEXT); 
       } else if (type == DOC) { 
        File targetFile = new File(path); 
        Uri targetUri = Uri.fromFile(targetFile); 
        Intent intent = new Intent(Intent.ACTION_VIEW); 
        intent.setDataAndType(targetUri, "application/*"); 
        startActivityForResult(intent, DOC); 
       } else if (type == EXCEL) { 
        File targetFile = new File(path); 
        Uri targetUri = Uri.fromFile(targetFile); 
        Intent intent = new Intent(Intent.ACTION_VIEW); 
        intent.setDataAndType(targetUri, "application/*"); 
        startActivityForResult(intent, EXCEL); 
       } else { 
        File targetFile = new File(path); 
        Uri targetUri = Uri.fromFile(targetFile); 
        Intent intent = new Intent(Intent.ACTION_VIEW); 
        intent.setDataAndType(targetUri, "application/*"); 
        startActivityForResult(intent, 0); 
       }

爲此使用Webview。它爲我工作。

WebView mWebView = (WebView) findViewById(R.id.WebView01); 
String pdfurl = ""; // Url of pdf or doc file. 

String weblink="http://docs.google.com/gview?embedded=true&url="+pdfurl;  
mWebView.loadUrl(weblink);
