Question

我使用以下代码就可以了。所有的http网址都在webview中打开，“tel：”链接在拨号器中打开，“mailto：”链接在电子邮件客户端中打开。

但我的问题是如何将“mailto：”链接的主题更改为不同于预定义主题的内容。我猜测应该有2个单独的意图，1个用于“tel：”链接＆amp; 1为“mailto：”链接。我根本不知道如何将代码放入下面的shouldOverrideUrlLoading方法中。或者我可能正在使用错误的方法来满足我的需求。

        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if( url.startsWith("http:") || url.startsWith("https:") ) {
                return false;
            }

            // Otherwise allow the OS to handle it
            Intent intent = new Intent(Intent.ACTION_VIEW,
                    Uri.parse(url));
            startActivity(intent);
            return true;
        }

我设法让我自己的主题“mailto：”与Intent一起工作，但代码中没有包含“tel：”链接。那么如何才能在“mailto：”链接中使用我自己的主题？

非常感谢任何想法或建议！

这是我的解决方案＆amp;这个对我有用。我希望它能帮助其他人解决我遇到的同样问题。

@Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if( url.startsWith("http:") || url.startsWith("https:") ) {
                return false;
            }

            // Otherwise allow the OS to handle it
            else if (url.startsWith("tel:")) { 
                Intent tel = new Intent(Intent.ACTION_DIAL, Uri.parse(url)); 
                startActivity(tel);
                return true;
            }
            else if (url.startsWith("mailto:")) {
                String body = "Enter your Question, Enquiry or Feedback below:\n\n";
                Intent mail = new Intent(Intent.ACTION_SEND);
                mail.setType("application/octet-stream");
                mail.putExtra(Intent.EXTRA_EMAIL, new String[]{"email address"});
                mail.putExtra(Intent.EXTRA_SUBJECT, "Subject");
                mail.putExtra(Intent.EXTRA_TEXT, body);
                startActivity(mail);
                return true;
                }
            return true;
        }

@Override
        public boolean shouldOverrideUrlLoading(WebView wv, String url) {


            if(url.startsWith(TEL_PREFIX)) {
                Intent intent = new Intent(Intent.ACTION_DIAL);
                intent.setData(Uri.parse(url));
                startActivity(intent);
                return true;
            }
            if (url.startsWith("mailto:")) {


                String body = "Enter your Question, Enquiry or Feedback below:\n\n";


                Intent email = new Intent(Intent.ACTION_SEND);
                email.putExtra(Intent.EXTRA_EMAIL, new String[]{"a.ee.ee@rt.com"});
                email.putExtra(Intent.EXTRA_SUBJECT, "Subject");
                email.putExtra(Intent.EXTRA_TEXT, body);
                //need this to prompts email client only
                email.setType("message/rfc822");
                startActivity(Intent.createChooser(email, "Choose an Email client :"));


                return true;
                }
            return false;
        }
    });

当您检测到mailto时：尝试向其添加“？subject = custom”。我猜是这样的事情：

if (url.startsWith("mailto:")) {
    Uri mailWithSubject = Uri.parse(url).
            buildUpon().appendQueryParameter("subject", "Hello World!").build();
    Intent intent = new Intent(Intent.ACTION_VIEW, mailWithSubject);
    ...
}

为所有mailto链接收件人填写MainActivity。

@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
    if( url.startsWith("http:") || url.startsWith("https:") ) {
        return false;
    }
    // Otherwise allow the OS to handle it
    else if (url.startsWith("tel:")) {
        Intent tel = new Intent(Intent.ACTION_DIAL, Uri.parse(url));
        startActivity(tel);
        return true;
    }
    else if (url.startsWith("mailto:")) {
        String body = "Enter your Question, Enquiry or Feedback below:\n\n";
        Intent mail = new Intent(Intent.ACTION_SEND);

        Intent intent = mail.setType("application/octet-stream");

        // use for any mailto link for the recipient
        MailTo recipient = MailTo.parse(url);
        mail.putExtra(Intent.EXTRA_EMAIL, new String[]{recipient.getTo()});

        mail.putExtra(Intent.EXTRA_SUBJECT, "Subject");
        mail.putExtra(Intent.EXTRA_TEXT, body);
        startActivity(mail);
        return true;
    }
    return true;
}
