android 几种发送短信的方法
android中发送短信很简单，
首先要在Mainfest.xml中加入所需要的权限：
|
1
2
3
|
<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：
|
1
2
3
4
5
6
7
8
9
10
11
12
13

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
|
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
28
29
30
31
32
33
34
35
36
37
38

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：
|
1
2
3
4
5
6
|
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
|
1
2
3
4
5
|
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
|
1
2
3
4
5
6
|
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
|
1
2
3
4
5
6
7
|
<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
|
1
2
3
4
5
6
7
8
9
10
|
<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。
