我不能显示ppt事实上我想不仅显示ppt而且在视图中显示doc/ppt/pdf/xls文件.....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);`

正如你在上面看到的，代码是在我的android平板电脑上显示一个MS ppt。

现在我的代码过程如下所示。

1.我将从URL下载ppt并将其存储在sdcard中。

2.然后我想在一个我认为完全适合的视图中显示ppt。

所以我不能显示ppt事实上我想不仅显示ppt而且在视图中显示doc/ppt/pdf/xls文件.....

那么该怎么做呢？

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);
                }

为此，请使用Webview。这对我很管用。

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);
