Question

我想在我的 AlertDialog 中显示 link，但多次尝试后它仍然显示为纯文本。

我尝试了以下link中的建议： How can I get clickable hyperlinks in AlertDialog from a string resource?

Android link in dialog

这是我目前的状态：

     final TextView msg = new TextView(context);
    final SpannableString s = new SpannableString("https://play.google.com/store/apps/details?id=com.google.zxing.client.android");
    Linkify.addLinks(s, Linkify.WEB_URLS);
    msg.setText("BradcodeScanner app must be installed on your phone\n" +
               "click on the link below.\n\n" +s);
    msg.setMovementMethod(LinkMovementMethod.getInstance());

    info_img = (ImageView) findViewById(R.id.qr_info);
    info_img.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v)
        {
            new AlertDialog.Builder(context)
                    .setTitle("QR Location Scan")
                    .setView(msg)
                            .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog, int which) {
                                    return;
                                }
                            })
                                    .setIcon(android.R.drawable.ic_dialog_info)
                                    .show();
        }
    });

Answer 1

你的意思是这样的吗？

mTvContent.setPaintFlags(mTvContent.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);
mTvContent.setTextColor(ContextCompat.getColor(this, R.color.aviary_accent_blue));
mTvContent.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if (link.contains("http://")) {
        Intent i = new Intent();
        i.setAction(Intent.ACTION_VIEW);
        i.setData(Uri.parse(link));
        context.startActivity(i);
    } else {
        link = "http://" + link;
        Intent i = new Intent();
        i.setAction(Intent.ACTION_VIEW);
        i.setData(Uri.parse(link));
        context.startActivity(i);
    }
    }
});

超链接仅在 HTML 文本中有效。所以你必须：

msg.setText(Html.fromHtml("BradcodeScanner app must be installed on your phone</br><a href=\"" + s + "\">click here</a>");
