не удалось разобрать строку на целое число в eclipse

Я подключаю свое приложение к последовательному соединению bluetooth. Я хочу изменить данные, которые являются String, Integer, поэтому я могу сравнить его.не удалось разобрать строку на целое число в eclipse

Это тот случай, читая сообщения:

case MESSAGE_READ: 
    byte[] readBuf = (byte[]) msg.obj;    

    // construct a string from the valid bytes in the buffer 
    String readMessage = new String(readBuf, 0, msg.arg1); 
    Log.i(LOG_TAG, readMessage); 

    mTextView.setText(readMessage); 
    if(mTextView!=null){ 
     int read = Integer.parseInt(readMessage.trim()); 
    if (read<1 && read>28){ 
     alarm(); 
     sendSMS(); 
    } 
    } 
    /* int read = new Integer(readMessage.trim()); 
    if (read<1&&read>28){ 
     alarm(); 
     sendSMS(); 
    }*/ 
    /*if (readMessage.trim().equalsIgnoreCase("20")) 
    { 
     alarm(); 
     sendSMS(); 
    }*/ 
    break;

И в LogCat:

Тогда я изменить его на:

в случае сообщение:

       int i; 
       byte[] readBuf = (byte[]) msg.obj;    

      // construct a string from the valid bytes in the buffer 
       String readMessage = new String(readBuf, 0, msg.arg1); 
       Log.i(LOG_TAG, readMessage); 

       mTextView.setText(readMessage); 

       List<Integer> integers = new ArrayList<Integer>(); 
       String [] numbers = readMessage.split("\n"); 
       for (String number : numbers) { 
        integers.add(Integer.valueOf(number.trim())); 
       } 


       /* int read = new Integer(readMessage.trim()); 
       if (read<1&&read>28){

Пожалуйста, поделитесь строку кода FinalSetting.java:352, его внешний вид, как вы пытаетесь не разобрать недопустимые нет – Imran

Ваше сообщение содержит строку с большим количеством цифр, на отдельных строках. Вы не можете разобрать такую строку в одном целых числах - вы получите свою ошибку.

Вы можете попробовать чтение целочисленный массив так:

List<Integer> integers = new ArrayList<Integer>(); 
String [] numbers = readMessage.split("\n"); 
for (String number : numbers) { 
    integers.add(Integer.valueOf(number.trim())); 
}

После этого кода integers будет содержать номера, которые вы получаете в сообщении.

спасибо, я следовать инструкциям ур, но все еще есть ошибки. Для получения полной информации просмотрите мой новый отредактированный вопрос: D –

У меня была такая же проблема, когда я окружил ее блоком try-catch, он начал работать. как:

try 
    { 
    size_of_file=Integer.parseInt(Value); 
    } 
    catch(Exception obj) 
    { 
     Toast.makeText(this, "Error :"+obj.getMessage(), Toast.LENGTH_LONG).show(); 
    }
