Android发送短信

android中发送短信很简单，

首先要在Mainfest.xml中加入所需要的权限：

为了后面测试方便，干脆把SMS的所有权限加上。

方法1：

public class testSms extends Activity \{

…

private void send1(String phone, String message){
    
        PendingIntent pi = PendingIntent.getActivity(this, 0, new Intent(this, testSms.class), 0);
    
        SmsManager sms = SmsManager.getDefault();
    
        sms.sendTextMessage(phone, null, message, pi, null);
    
    }

方法2：

如果想知道短信发送后的状态，需要两个Receiver来实现

private void send2(String number, String message)\{  
String SENT = “sms\_sent”;  
String DELIVERED = “sms\_delivered”;

PendingIntent sentPI = PendingIntent.getActivity(this, 0, new Intent(SENT), 0);
    PendingIntent deliveredPI = PendingIntent.getActivity(this, 0, new Intent(DELIVERED), 0);
    
    registerReceiver(new BroadcastReceiver(){
    
            @Override
            public void onReceive(Context context, Intent intent) {
                switch(getResultCode())
                {
                    case Activity.RESULT_OK:
                        Log.i("====>", "Activity.RESULT_OK");
                        break;
                    case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                        Log.i("====>", "RESULT_ERROR_GENERIC_FAILURE");
                        break;
                    case SmsManager.RESULT_ERROR_NO_SERVICE:
                        Log.i("====>", "RESULT_ERROR_NO_SERVICE");
                        break;
                    case SmsManager.RESULT_ERROR_NULL_PDU:
                        Log.i("====>", "RESULT_ERROR_NULL_PDU");
                        break;
                    case SmsManager.RESULT_ERROR_RADIO_OFF:
                        Log.i("====>", "RESULT_ERROR_RADIO_OFF");
                        break;
                }
            }
    }, new IntentFilter(SENT));
    
    registerReceiver(new BroadcastReceiver(){
        @Override
        public void onReceive(Context context, Intent intent){
            switch(getResultCode())
            {
                case Activity.RESULT_OK:
                    Log.i("====>", "RESULT_OK");
                    break;
                case Activity.RESULT_CANCELED:
                    Log.i("=====>", "RESULT_CANCELED");
                    break;
            }
        }
    }, new IntentFilter(DELIVERED));
    
        SmsManager smsm = SmsManager.getDefault();
        smsm.sendTextMessage(number, null, message, sentPI, deliveredPI);

在模拟器上是看不到Receiver中的log信息的，据网上说在手机上是可以实现的，只可惜手中无机，也只能纸上谈兵了。

方法3：

上面都是发送文本文件，如果想发送一些非文本，比如加密数据，可以用以下方法：

private void send2(String number, String message)\{  
SmsManager smsm = SmsManager.getDefault();  
short port = 1000;  
PendingIntent pi = PendingIntent.getBroadcast(test.this, 0, new Intent(), 0);  
smsm.sendDataMessage(number, null, port, message.getBytes(), pi, null);  
\}

方法4：

调用系统的短信界面，这个方法需要用户自己输入接收方的电话号码

private void send(String message)\{  
Intent sendIntent = new Intent(Intent.ACTION\_VIEW);  
sendIntent.putExtra(“sms\_body”, message);  
sendIntent.setType(“vnd.android-dir/mms-sms”);  
\}

这个方法自动设置接收方的号码

private void send1(String number, String message)\{  
Uri uri = Uri.parse(“smsto:” + number);  
Intent sendIntent = new Intent(Intent.ACTION\_VIEW, uri);  
sendIntent.putExtra(“sms\_body”, message);  
startActivity(sendIntent);  
\}

短信的接受，需要实现BroadcastReceiver类，监听系统消息

首先在Mainfest.xml中加入申明，SmsReceiver为实现类

如果是方法3，使用sendDataMessage时需要加入

将其中的dat数据注释掉，模拟器上也可以接收到短信； port跟sendDataMessage中的端口值不一致时，也没有问题，太神奇了

public class SmsReceiver extends BroadcastReceiver \{

@Override
    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras();
        SmsMessage[] msgs = null;
        String phone;
        String message;
    
        if(bundle != null){
            Object[] pdus = (Object[])bundle.get("pdus");
            msgs = new SmsMessage[pdus.length];
            for(int i = 0; i < msgs.length; i++){
                msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
                phone = msgs[i].getOriginatingAddress();
                message = msgs[i].getMessageBody();
            }
        }
    }

如果是sendDataMessage发送：

public class SmsReceiver extends BroadcastReceiver \{

@Override
    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras();
        SmsMessage[] msgs = null;
             String phone;
             String message;
    
        if(bundle != null){
            Object[] pdus = (Object[])bundle.get("pdus");
            msgs = new SmsMessage[pdus.length];
            for(int i = 0; i < msgs.length; i++){
                msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
                phone = msgs[i].getOriginatingAddress();
                byte data[] = SmsMessage.createFromPdu((byte[])pdus[i]).getUserData();
                message = new String(data);
            }
        }
    }

不一样的地方是message的获取时使用getUserData()方法。
