Suggestion : continuous calls of StringBuilder.append

[o0lwj0o]

Hi,
    I have found some continuous calls about StringBuilder.append(..) in some files. For example, there are several continuous calls from line 61 to 76 in the file https://github.com/hprose/hprose-java/blob/master/example/MyApplication/app/src/main/java/org/hprose/myapplication/MainActivity.java

public void run() {
                            TextView text = (TextView)findViewById(R.id.textView);
                            StringBuilder sb = new StringBuilder();
                            for (int i = 0; i < users.length; i++) {
                                sb.append("name: ");
                                sb.append(users[i].name);
                                sb.append("\r\n");
                                sb.append("sex: ");
                                sb.append(users[i].sex);
                                sb.append("\r\n");
                                sb.append("birthday: ");
                                sb.append(users[i].birthday);
                                sb.append("\r\n");
                                sb.append("age: ");
                                sb.append(users[i].age);
                                sb.append("\r\n");
                                sb.append("married: ");
                                sb.append(users[i].married);
                                sb.append("\r\n");
                                sb.append("\r\n");
                            }
                            text.setText(sb.toString());
}

    If it was achieved like StringBuilder.append(..).append(..)append(..), it will promote its performance.
