我要在我的WebView打开PDF，我发现，结合codeS在这个论坛。

但它抓住我虽然安装了多个PDF的应用程序，包括未找到PDF的应用程序安装Adobe Reader。

下面的code：

 私有类PsvWebViewClient扩展WebViewClient {
        @覆盖
        公共布尔shouldOverrideUrlLoading（web视图查看，字符串URL）{
            view.loadUrl（URL）;

            如果（url.contains（PDF））{
                URI路径= Uri.parse（URL）;
                意图pdfIntent =新的意图（Intent.ACTION_VIEW）;
                pdfIntent.setDataAndType（道路，应用程序/ PDF格式）;
                pdfIntent.setFlags（Intent.FLAG_ACTIVITY_CLEAR_TOP）;

                尝试
                {
                    startActivity（pdfIntent）;
                }
                赶上（ActivityNotFoundException E）
                {
                    Toast.makeText（PsvWebViewActivity.this，没有PDF应用程序中发现，Toast.LENGTH_SHORT）.show（）;
                }
                赶上（例外otherException）
                {
                    Toast.makeText（PsvWebViewActivity.this，未知错误，Toast.LENGTH_SHORT）.show（）;
                }

            }

            返回true;
        }}}
 

解决方案

您无法打开PDF直接在android的网页浏览器，但使用谷歌文档查看器，你可以在Android浏览器中打开它就像......

  mWebView.loadUrl（https://docs.google.com/gview?embedded=true&url=+ WEBURL）;
 

I want to open a PDF in my WebView, and I found and combined codes on this forum.

But it catches the "No PDF application found" although I have multiple PDF apps installed, including Adobe Reader.

Here the code:

private class PsvWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);

            if (url.contains(".pdf")) {
                Uri path = Uri.parse(url); 
                Intent pdfIntent = new Intent(Intent.ACTION_VIEW);
                pdfIntent.setDataAndType(path, "application/pdf");
                pdfIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

                try
                {
                    startActivity(pdfIntent);
                }
                catch(ActivityNotFoundException e)
                {
                    Toast.makeText(PsvWebViewActivity.this, "No PDF application found", Toast.LENGTH_SHORT).show();
                }
                catch(Exception otherException)
                {
                    Toast.makeText(PsvWebViewActivity.this, "Unknown error", Toast.LENGTH_SHORT).show();
                }

            }

            return true;
        }   } }

You cant open pdf directly in android web browser But Using google Docs Viewer you can open it in android Browser like......

mWebView.loadUrl("https://docs.google.com/gview?embedded=true&url="+ webUrl);
