通过android意图打开在线pdf文件? [英] Open online pdf file through android intent?

问题描述

目前我有一个 pdf url，我想简单地使用意图打开它，但是，如果我将 url 放在 <代码>意图

Currently I have a pdf url, and I would like to simply using the intent to open it, however, it does not work if I put the url in intent

我的代码是这样的，总是抛出ActivityNotFoundException错误

My code is like this, it always throw ActivityNotFoundException error

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse(law.url), "application/pdf");

try {
    startActivity(intent);
} catch (ActivityNotFoundException e){
    Utility.showErrorDialog(
        ctx,ctx.getResources().getString(R.string.sys_in, 
        ctx.getResources().getString(R.string.err_no_pdf_reader), 
        ctx.getResources().getString(R.string.close));
}

我也尝试过goolge doc方法，但我的客户拒绝了，所以我没有使用这种方法

Also I tried the goolge doc approach but my client reject this, so I am not using this method

Intent intent = new Intent(Intent.ACTION_VIEW);

intent.setDataAndType(Uri.parse("http://docs.google.com/viewer?url=" 
+ publish.get(Integer.parseInt((String) view.getTag())).pdfURL), "text/html");  
ctx.startActivity(intent);

感谢帮助

推荐答案

您可以通过以下两种方式之一查看或下载 pdf，即通过在设备内置浏览器中打开它或通过将其嵌入您的应用程序在 webview 中打开它.

You can view or download the pdf by either of the two ways i.e by opening it in device in-built browser or in the webview by embedding it in your app.

要在浏览器中打开 pdf，

To open the pdf in browser,

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(pdf_url));
startActivity(browserIntent);

改为在 webview 中打开，

Instead to open in webview,

 WebView webView = (WebView) findViewById(R.id.webView1);
 webView.getSettings().setJavaScriptEnabled(true);
 webView.loadUrl(pdf_url);
