如何在警报对话框中链接到Facebook页面等网页

Question

我想在警报对话框中添加我的（Facebook页面）链接，如下所示：

public void visitFAcebook(){
    new AlertDialog.Builder(this)
            .setTitle("Find Us On Facebook")
            .setMessage("www.facebook.com/mypage")
            .show();
}

我可以将消息转换为可点击的链接吗？

对代码进行以下更改。您可以更改颜色和字体，如下所示。

public void visitFacebook(){
        String fbLink = "<a href="http://www.facebook.com/mypage">My Facebook Page</a>";
        String Txt = "Click to visit facebook: "+"<h1>"+"<font color=blue>"+ fbLink+"</font></h1>";
        Spanned fbString = Html.fromHtml(Txt);

        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Title");
        builder.setMessage(fbString);
        builder.setCancelable(true);
        AlertDialog alertDialog = builder.create();
        alertDialog.show();
        TextView msgTxt = (TextView) alertDialog.findViewById(android.R.id.message);
        msgTxt.setMovementMethod(LinkMovementMethod.getInstance());
    }

安卓仅支持以下标签

<a href="...">
<b>
<big>
<blockquote>
<br>
<cite>
<dfn>
<div align="...">
<em>
<font size="..." color="..." face="...">
<h1>
<h2>
<h3>
<h4>
<h5>
<h6>
<i>
<img src="...">
<p>
<small>
<strike>
<strong>
<sub>
<sup>
<tt>
<u>
