android中發送短信很簡單，
首先要在Mainfest.xml中加入所需要的權限：
爲了後面測試方便，乾脆把SMS的所有權限加上。
方法1：
發送短信 需要真機來測試
public class testSms extends Activity {
…
private void send1(String phone, String message){
PendingIntent pi = PendingIntent.getActivity(this, 0, new Intent(this, testSms.class), 0); //意圖
/*
PendingIntent.getBroadcast(context, requestCode, intent, flags);
PendingIntent.getActivity(context, requestCode, intent, flags);
PendingIntent.getService(context, requestCode, intent, flags);
*/
SmsManager sms = SmsManager.getDefault(); // 短信管理
sms.sendTextMessage(phone, null, message, pi, null);
// 發送短信 phone 電話號碼 ，message 短信 ，pi 意圖
}
}
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(){ // 實現一個匿名類廣播
@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)); // new IntentFilter(deliver); 過濾器
SmsManager smsm = SmsManager.getDefault();
smsm.sendTextMessage(number, null, message, sentPI, deliveredPI);
}
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
// 會跳轉到系統的發送短信界面
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
如果是方法3，使用sendDataMessage時需要加入
將其中的data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"); // 通過pdu 來接收信息
msgs = new SmsMessage[pdus.length];
for(int i = 0; i < msgs.length; i++){
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
phone = msgs[i].getOriginatingAddress(); // 電話號碼
message = msgs[i].getMessageBody();// 短信內容
/*
同一個號碼的短信放在一起
phone = msgs[0].getOriginatingAddress(); // 電話號碼
String fullmessage = new String();
for(SmsMessage x:smsmessage){
fullmessage+=x.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);
}
}
}
}
不一樣的地方是message的獲取時使用getUserData()方法。
