Android:发送短信时的Unicode /字符集问题(sendTextMessage)

标签: android sms special-characters character-encoding

基本上我有一个工作的应用程序,在收到短信后发送短信。

一切正常,除非短信发送有“特殊字符”,即“é,à,í,ç”等。

我尝试了很多东西,包括charset转换,但我根本无法使它工作...... msgText总是带回charset编码问题。

以下是发送消息的部分:

if (msgText.length() > 160) {
    ArrayList msgTexts = sm.divideMessage(msgText);
    sm.sendMultipartTextMessage(PhoneNumber, null, msgTexts, null, null);
} else {
    try {
        sm.sendTextMessage(PhoneNumber, null, msgText, null, null);
    } catch (IllegalArgumentException e) {
        e.printStackTrace();
    }
}

这是我尝试的charset转换函数(但没有帮助),我在msgText上应用了:

public static String formatCharset(String txtInicial) {
    //-- Please notice this is just for reference, I tried every charset from/to conversion possibility. Even stupid ones and nothing helped.

    /*try {//-- Seems simpler, it should do the same as below, but didn't help
        msgText = new String(msgText.getBytes("UTF-8"), "ISO-8859-1");
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
    }*/

    Charset charsetOrigem = Charset.forName("UTF-8");
    CharsetEncoder encoderOrigem = charsetOrigem.newEncoder();
    Charset charsetDestino = Charset.forName("ISO-8859-1");
    CharsetDecoder decoderDestino = charsetDestino.newDecoder();

    String txtFinal = "";

    try {
        ByteBuffer bbuf = encoderOrigem.encode(CharBuffer.wrap( txtInicial ));
        CharBuffer cbuf = decoderDestino.decode(bbuf);
        txtFinal = cbuf.toString();
    } catch (CharacterCodingException e) {
        e.printStackTrace();
    }

    if (txtFinal.length() == 0) txtFinal = txtInicial;

    return txtFinal;
}

近乎绝望我甚至在这里尝试了unicode消息传递的解决方案(也没有帮助):

无论如何,这里(清理 - 包是com.THE.APPLICATION,主要活动是MAINACT)LogCat用于崩溃时(尝试发送消息时,收到消息后):

要发送问题的消息文本示例:

VERBOSE/debug_tag(28218): msgText is: possível.

因此, 可能 可能 可能

请一些开明的灵魂帮助我。他/她在我心中会有一个特殊的位置! :)

编辑:如果我心中的特殊地方没有削减它,我愿意花几块钱购买解决方案......

好的,只需使用sendMultipartTextMessage代替sendTextMessage即可解决此问题。

谁会想到......这有点意义,因为unicode角色比“普通”角色使用更多“空间”。

答案 1 :(得分:2)

我已使用此代码将UTF-8字符转换为ASCII。然后发送短信工作,我可以使用160个字符:

private static final String PLAIN_ASCII = "AaEeIiOoUu" // grave
        + "AaEeIiOoUuYy" // acute
        + "AaEeIiOoUuYy" // circumflex
        + "AaOoNn" // tilde
        + "AaEeIiOoUuYy" // umlaut
        + "Aa" // ring
        + "Cc" // cedilla
        + "OoUu" // double acute
;

private static final String UNICODE = "\u00C0\u00E0\u00C8\u00E8\u00CC\u00EC\u00D2\u00F2\u00D9\u00F9"
        + "\u00C1\u00E1\u00C9\u00E9\u00CD\u00ED\u00D3\u00F3\u00DA\u00FA\u00DD\u00FD"
        + "\u00C2\u00E2\u00CA\u00EA\u00CE\u00EE\u00D4\u00F4\u00DB\u00FB\u0176\u0177"
        + "\u00C3\u00E3\u00D5\u00F5\u00D1\u00F1"
        + "\u00C4\u00E4\u00CB\u00EB\u00CF\u00EF\u00D6\u00F6\u00DC\u00FC\u0178\u00FF"
        + "\u00C5\u00E5" + "\u00C7\u00E7" + "\u0150\u0151\u0170\u0171";

// remove accentued from a string and replace with ascii equivalent
public static String convertNonAscii(String s) {
    if (s == null)
        return null;
    StringBuilder sb = new StringBuilder();
    int n = s.length();
    for (int i = 0; i < n; i++) {
        char c = s.charAt(i);
        int pos = UNICODE.indexOf(c);
        if (pos > -1) {
            sb.append(PLAIN_ASCII.charAt(pos));
        } else {
            sb.append(c);
        }
    }
    return sb.toString();
}

答案 2 :(得分:1)

我正在使用此命令行:

Html.fromHtml(new String(myString.getBytes("UTF-8"))).toString();

我的短信看起来很完美。

答案 3 :(得分:0)

如果是7位编码,则只能使用160个字符。如果使用140个字符,它应该在没有sendMultipartTextMessage的情况下工作,因为你使用的是8位字符(UTF-8)。

答案 4 :(得分:0)

我对特殊字符有同样的问题。当我将消息MAX_SMS_MESSAGE_LENGTH更改为70时,一切正常。看看那个链接:

https://forums.macrumors.com/threads/special-characters-in-sms-turn-them-shorter-70-characters-old-issue-never-solved.1030577/

这是我的代码:

    public static void sendSMS(String phoneNumber, String message, Context context) {

    String SENT = "SMS_SENT";
    int MAX_SMS_MESSAGE_LENGTH = 70;

    SmsManager smsManager = SmsManager.getDefault();
    PendingIntent sentPI;
    sentPI = PendingIntent.getBroadcast(context, 0,new Intent(SENT), 0);

    try {
        if(message.length() > MAX_SMS_MESSAGE_LENGTH) {
            ArrayList<String> messageList = SmsManager.getDefault().divideMessage(message);
            smsManager.sendMultipartTextMessage(phoneNumber, null, messageList, null, null);
        } else {
            smsManager.sendTextMessage(phoneNumber, null, message, sentPI, null);
        }
    } catch (Exception e) {
        Log.e("SmsProvider", "" + e);
    }
}

当然你可以插入一个控制器来检查消息是否包含一些特殊字符,然后将MAX_SMS_MESSAGE_LENGTH从160更改为70.我的应用程序中总是有特殊字符。
