Question

我想在电子邮件正文中插入html代码...在我的代码中，我在后台发送电子邮件意味着onClick按钮事件，因为每当我在BasicNameValuePair中使用Html.formHtml时，它会在此行显示错误..请救命谢谢

@Override
public void onClick(View arg)
{
    String site = "http://2233.comoj.com/mailer.php";
    String namer1 = "password";
    String to = "abc@gmail.com";
    String from = "xyz@gmail.com";
    String subject1 = "checking mail";
    String message = "<html><head><body><h1>Hello World</h1></body></head></html>";
    String content = "";

    try
    {
        /* Sends data through a HTTP POST request */
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(site);
        List<NameValuePair> params = new ArrayList<NameValuePair>();
        params.add(new BasicNameValuePair("name", namer1));
        params.add(new BasicNameValuePair("to", to));
        params.add(new BasicNameValuePair("from", from));
        params.add(new BasicNameValuePair("subject", subject1));
        params.add(new BasicNameValuePair("message", Html.fromHtml(message))); //error in this line 
        httpPost.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
        /* Reads the server response */
        HttpResponse response = httpClient.execute(httpPost);
        InputStream in = response.getEntity().getContent();
        StringBuffer sb = new StringBuffer();
        int chr;
        while ((chr = in.read()) != -1)
        {
            sb.append((char) chr);
        }
        content = sb.toString();
        in.close();
        /* If there is a response, display it */
        if (!content.equals(""))
        {
            Log.i("HTTP Response", content);
        }
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

    Intent intent = new Intent(context, Invite2.class);
    startActivity(intent);
}

Answer 1

您需要在toString()方法上调用Html.fromHtml（因为它返回Spanned）才能将其作为NameValuePair内的值。

params.add(new BasicNameValuePair("message", Html.fromHtml(message).toString()));

Answer 2

根据Html参考方法fromHtml返回Spanned

我想你只需发送一个String

params.add(new BasicNameValuePair("message", message));

使用Html.fromHtml时构造函数BasicNameValuePair（String，Spanned）未定义（消息）
