Question

我为消息传递应用程序设置了一个非常简单的设置。我只是从EditText框中获取文本并将其作为参数传递给将其添加到我的数据库的php页面。它适用于一个单词条目。我在EditText框中放入一个空格的那一刻它不起作用。我在Android上还是比较新的。我真的不明白这是怎么回事。有谁知道这会怎么样？

这是我的onClick方法：

    public void sendMessage(View v) {
Log.d("tag", "XXXXXXXXXXXXXXXXXXXXXX");
        final SharedPreferences prefs = PreferenceManager
                .getDefaultSharedPreferences(getBaseContext());

        username = prefs.getString("username", "null");



where = prefs.getString("chat", "null");
        message = (EditText) findViewById(R.id.inptbox);

        function = new Functions();
        Editable messagetext;
messagetext = message.getText();


                response = function.sendMessage(username, where, messagetext.toString());
String theresponse = "";
theresponse = response;
                if (theresponse.compareTo("0") == 0) {
                    Toast.makeText(getApplicationContext(), "Success!",
                            Toast.LENGTH_SHORT).show();
                    //message.setText(null);

                } else if (response.compareTo("9") == 0) {

                    // userent.setText("nine");

                }

    }

我的function.sendMessage：

    public String sendMessage(String username, String where, String string){

        BufferedReader in = null;
        String data = null;
        try{


            HttpClient client = new DefaultHttpClient();
            URI website = new URI("http://abc.com/user_send.php?username="+username+"&where="+where+"&message="+string);

            HttpPost post_request = new HttpPost();
            post_request.setURI(website);


            HttpGet request = new HttpGet();

            request.setURI(website);
            //executing actual request

                        //add your implementation here
            HttpResponse response = client.execute(request);

            in = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
            StringBuffer sb = new StringBuffer("");
            String l = "";
            String nl = System.getProperty("line.separator");
            while ((l = in.readLine()) != null) {
                sb.append(l+nl);

            }
            in.close();
            data = sb.toString();


return data;
        }catch (Exception e){
            return "ERROR";

        }

        }

我该如何解决这个问题呢？

您必须对邮件进行编码，使其“网址安全”。空格（和其他特殊字符）不能出现在网址中;这就是为什么如果您在地址栏中键入空格，您的浏览器将用%20替换空格。在function.sendMessage（）中尝试以下内容：

URI website = new URI("http://abc.com/user_send.php?username="+username+"&where="+where+"&message="+URLEncoder.encode(string, "UTF-8"));

请注意最后使用URLEncoder。

将EditText.getText（）发送到服务器。仅适用于单个单词。怎么样？
