如何从内置web浏览器而不是应用程序中的代码打开URL？
我试过了：
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();
}
但我有个例外：
No activity found to handle Intent{action=android.intent.action.VIEW data =www.google.com

只需使用简短的一个，即可在浏览器中打开您的Url：
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("YourUrlHere"));
startActivity(browserIntent);
其他回答
//OnClick侦听器
@Override
public void onClick(View v) {
String webUrl = news.getNewsURL();
if(webUrl!="")
Utils.intentWebURL(mContext, webUrl);
}
//你的Util方法
public static void intentWebURL(Context context, String url) {
if (!url.startsWith("http://") && !url.startsWith("https://")) {
url = "http://" + url;
}
boolean flag = isURL(url);
if (flag) {
Intent browserIntent = new Intent(Intent.ACTION_VIEW,
Uri.parse(url));
context.startActivity(browserIntent);
}
}
其他选项使用Webview在同一应用程序中加载Url
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.google.com");
在Android 11中打开URL链接的新的更好方法。
try {
val intent = Intent(ACTION_VIEW, Uri.parse(url)).apply {
// The URL should either launch directly in a non-browser app
// (if it’s the default), or in the disambiguation dialog
addCategory(CATEGORY_BROWSABLE)
flags = FLAG_ACTIVITY_NEW_TASK or FLAG_ACTIVITY_REQUIRE_NON_BROWSER or
FLAG_ACTIVITY_REQUIRE_DEFAULT
}
startActivity(intent)
} catch (e: ActivityNotFoundException) {
// Only browser apps are available, or a browser is the default app for this intent
// This code executes in one of the following cases:
// 1. Only browser apps can handle the intent.
// 2. The user has set a browser app as the default app.
// 3. The user hasn't set any app as the default for handling this URL.
openInCustomTabs(url)
}

实现这一点的常见方法是使用以下代码：
String url = "http://www.stackoverflow.com";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
可以更改为短代码版本。。。
Intent intent = new Intent(Intent.ACTION_VIEW).setData(Uri.parse("http://www.stackoverflow.com"));
startActivity(intent);
or :
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.stackoverflow.com"));
startActivity(intent);
最短！：
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.stackoverflow.com")));
我认为这是最好的
openBrowser(context, "http://www.google.com")
将以下代码放入全局类
public static void openBrowser(Context context, String url) {
if (!url.startsWith("http://") && !url.startsWith("https://"))
url = "http://" + url;
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
context.startActivity(browserIntent);
}
