android中发送短信很简单，

首先要在Mainfest.xml中加入所需要的权限：

<uses-permission android:name="android.permission.SEND_SMS"></uses-permission>
<uses-permission android:name="android.permission.READ_SMS"></uses-permission>
<uses-permission android:name="android.permission.RECEIVE_SMS"></uses-permission>

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);
}

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

<receiver android:name=".SmsReceiver"> 

<intent-filter> 
    <action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter> 

</receiver>

如果是方法3，使用sendDataMessage时需要加入

<receiver android:name=".SmsReceiver"> 

<intent-filter> 
    <action android:name="android.intent.action.DATA_SMS_RECEIVED" />
    <data android:scheme="sms" />
    <data android:host="localhost" />
    <data android:port="1000" />
</intent-filter>

</receiver>

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);
            }
        }
    }
}
