我怎样才能从一个字符串资源在AlertDialog点击超链接？ [英] How can I get clickable hyperlinks in AlertDialog from a string resource?

问题描述

我试图做到的是要在由AlertDialog显示的信息文本可点击超链接。虽然AlertDialog实施高兴地强调和颜色的任何链接（使用中所定义; A HREF =...＆gt;在传递给Builder.setMessage字符串资源），提供的链接不会变成可点击

What I am trying to accomplish is to have clickable hyperlinks in the message text displayed by an AlertDialog. While the AlertDialog implementation happily underlines and colors any hyperlinks (defined using <a href="..."> in the string resource passed to Builder.setMessage) supplied the links do not become clickable.

在code我目前使用看起来像这样：

The code I am currently using looks like this:

new AlertDialog.Builder(MainActivity.this).setTitle(
        R.string.Title_About).setMessage(
        getResources().getText(R.string.about))
        .setPositiveButton(android.R.string.ok, null)
        .setIcon(R.drawable.icon).show();

我想避免使用web视图只显示文本片段，所以任何意见如何得到这个工作是非常AP preciated！

I'd like to avoid using a WebView to just display a text snippet, so any advice how to get this working is much appreciated!

推荐答案

如果你只是显示一些文字和网址在对话框[S]也许解决的办法是简单

If you are only showing some text and URL[s] in your dialog perhaps the solution is simpler

public static class MyOtherAlertDialog {

 public static AlertDialog create(Context context) {
  final TextView message = new TextView(context);
  // i.e.: R.string.dialog_message =>
            // "Test this dialog following the link to dtmilano.blogspot.com"
  final SpannableString s = 
               new SpannableString(context.getText(R.string.dialog_message));
  Linkify.addLinks(s, Linkify.WEB_URLS);
  message.setText(s);
  message.setMovementMethod(LinkMovementMethod.getInstance());

  return new AlertDialog.Builder(context)
   .setTitle(R.string.dialog_title)
   .setCancelable(true)
   .setIcon(android.R.drawable.ic_dialog_info)
   .setPositiveButton(R.string.dialog_action_dismiss, null)
   .setView(message)
   .create();
 }
}
