android - 带有自动链接的 TextView 上的 ActivityNotFoundException ="web"

Question

如果 TextView 因为显示网站而被点击，如何捕获 ActivityNotFoundException？

如果设备没有浏览器，则会抛出该异常。

XML:

<TextView
    android:id="@+id/tvTextView"
    android:autoLink="web" />

Java:

TextView tvTextView = (TextView) findViewById(R.id.tvTextView);
tvTextView.setText("http://www.stackoverflow.com/");

您可以使用以下方法检查是否有一个 Activity 来处理您的 Intent:

Intent intent = new Intent(Intent.ACTION_VIEW).setData(Uri.parse("http://www.stackoverflow.com"));
PackageManager manager = context.getPackageManager();
List<ResolveInfo> infos = manager.queryIntentActivities(intent, 0);
if (infos.size() > 0) {
    //At least one application can handle your intent 
    //Put this code in onCreate and only Linkify the TextView from here
    //instead of using android:autoLink="web" in xml
    Linkify.addLinks(tvTextView, Linkify.WEB_URLS);
    // or tvTextView.setAutoLinkMask(Linkify.WEB_URL), as suggested by Little Child
}else{
    //No Application can handle your intent, notify your user if needed
}
