Android發送短信的方法

加入所需要的權限：

<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>

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：

如果想知道短信發送後的狀態，需要兩個Receiver來實現

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);

}
在模擬器上是看不到Receiver中的log信息的

方法3：

上面都是發送文本文件，如果想發送一些非文本，比如加密數據，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：

調用系統的短信界面，這個方法需要用戶自己輸入接收方的電話號碼

private void send(String message){
    Intent sendIntent = new Intent(Intent.ACTION_VIEW);
    sendIntent.putExtra("sms_body", message);
    sendIntent.setType("vnd.android-dir/mms-sms");
}

這個方法自動設置接收方的號碼

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，需要實現BroadcastReceiver類，監聽系統消息

首先在Mainfest.xml中加入申明，SmsReceiver爲實現類

<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時需要加入

    <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>

將其中的dat數據註釋掉，模擬器上也可以接收到短信； port跟sendDataMessage中的端口值不一致時，也沒有問題，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發送：

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);
        }
    }
  }
}

message的獲取時使用getUserData()方法。
