android 中发送短信

android中发送短信

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

//---sends an SMS message to another device---
    private void sendSMS(String phoneNumber, String message)
    {       
        String SENT = "SMS_SENT";
        String DELIVERED = "SMS_DELIVERED";

        PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,
            new Intent(SENT), 0);

        PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0,
            new Intent(DELIVERED), 0);

        //---when the SMS has been sent---
        registerReceiver(new BroadcastReceiver(){
            @Override
            public void onReceive(Context arg0, Intent arg1) {
                switch (getResultCode())
                {
                    case Activity.RESULT_OK:
                        Toast.makeText(getBaseContext(), "SMS sent",
                                Toast.LENGTH_SHORT).show();
                        break;
                    case SmsManager.RESULT_ERROR_GENERIC_FAILURE:
                        Toast.makeText(getBaseContext(), "Generic failure",
                                Toast.LENGTH_SHORT).show();
                        break;
                    case SmsManager.RESULT_ERROR_NO_SERVICE:
                        Toast.makeText(getBaseContext(), "No service",
                                Toast.LENGTH_SHORT).show();
                        break;
                    case SmsManager.RESULT_ERROR_NULL_PDU:
                        Toast.makeText(getBaseContext(), "Null PDU",
                                Toast.LENGTH_SHORT).show();
                        break;
                    case SmsManager.RESULT_ERROR_RADIO_OFF:
                        Toast.makeText(getBaseContext(), "Radio off",
                                Toast.LENGTH_SHORT).show();
                        break;
                }
            }
        }, new IntentFilter(SENT));

        //---when the SMS has been delivered---
        registerReceiver(new BroadcastReceiver(){
            @Override
            public void onReceive(Context arg0, Intent arg1) {
                switch (getResultCode())
                {
                    case Activity.RESULT_OK:
                        Toast.makeText(getBaseContext(), "SMS delivered",
                                Toast.LENGTH_SHORT).show();
                        break;
                    case Activity.RESULT_CANCELED:
                        Toast.makeText(getBaseContext(), "SMS not delivered",
                                Toast.LENGTH_SHORT).show();
                        break;                       
                }
            }
        }, new IntentFilter(DELIVERED));       

        SmsManager sms = SmsManager.getDefault();
        sms.sendTextMessage(phoneNumber, 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

<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);
            }
        }
    }
}

不一样的地方是message的获取时使用getUserData()方法。
