android - Android 中的命名占位符

Question

在我的安卓应用中在消息中，如果我给出消息“你好#name，欢迎你的用户名:#username 和密码:#password”，在消息中#name，#username，#password 将被替换为我从 csv 文件读取的值它应该发送消息，例如:“嗨 praveen，欢迎您的用户名:neevarp 和密码:12345”这些值来自 csv。在搜索时我得到了一些链接

Named placeholders in string formatting

Map<String, String> values = new HashMap<String, String>();
values.put("value", x);
values.put("column", y);
StrSubstitutor sub = new StrSubstitutor(values, "%(", ")");
String result = sub.replace("There's an incorrect value '%(value)' in column # %(column)");

但是在安卓中

StrSubstitutor class is not there i think so is there any way to implement this

这是我从 csv 中读取值并通过替换占位符发送消息的代码

      public void sendingSms(String message, String file_path) {

    File file = new File("", file_path);

    // Read text from file

    try {
        BufferedReader br = new BufferedReader(new FileReader(file));
        String line;
        int iteration = 0;
        while ((line = br.readLine()) != null) {
            if (iteration != 0) {

                StringBuilder text = new StringBuilder();

                text.append(line);
                String[] contact = text.toString().split(",");
                String phoneNumber = contact[4];
                String name = contact[1];
                String username = contact[2];
                String password = contact[3];
      //here i have to replace place holders with name,username,password values
                //message.replace("#name", name);
                //message.replace("#user", username);

                Toast.makeText(Message.this, "" + message,
                        Toast.LENGTH_SHORT).show();

                 SmsManager smsManager = SmsManager.getDefault();
                 smsManager.sendTextMessage(phoneNumber, null, message, null,
                 null);

            }
            iteration++;
        }

    } catch (IOException e) {
        e.printStackTrace();
    }
}

您真的应该使用 Android 通过字符串资源提供的内置字符串格式:http://developer.android.com/guide/topics/resources/string-resource.html#FormattingAndStyling
