如何从我的应用程序在 Android 的 Web 浏览器中打开 URL? [英] How can I open a URL in Android's web browser from my application?

问题描述

如何在内置网络浏览器中而不是在我的应用程序中通过代码打开 URL?

How to open an URL from code in the built-in web browser rather than within my application?

我试过这个:

try {
    Intent myIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(download_link));
    startActivity(myIntent);
} catch (ActivityNotFoundException e) {
    Toast.makeText(this, "No application can handle this request."
        + " Please install a webbrowser",  Toast.LENGTH_LONG).show();
    e.printStackTrace();
}

但我有一个例外:

No activity found to handle Intent{action=android.intent.action.VIEW data =www.google.com

推荐答案

试试这个:

Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com"));
startActivity(browserIntent);

这对我来说很好.

至于缺少的http://"，我会这样做:

As for the missing "http://" I'd just do something like this:

if (!url.startsWith("http://") && !url.startsWith("https://"))
   url = "http://" + url;

我也可能会预先填充用户正在使用http://"键入 URL 的 EditText.

I would also probably pre-populate your EditText that the user is typing a URL in with "http://".
