Android创建简单发送和接收短信应用

// 接收短信的广播
class MessageReceiver extends BroadcastReceiver {
  @Override
  public void onReceive(Context context, Intent intent) {
    Bundle bundle = intent.getExtras();
    Object[] pdus = (Object[]) bundle.get("pdus"); // 提取短信消息
    SmsMessage[] messages = new SmsMessage[pdus.length];
    for (int i = 0; i < messages.length; i++) {
      messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
    }
    String address = messages[0].getOriginatingAddress(); // 获取发送方号码
    String fullMessage = "";
    for (SmsMessage message : messages) {
      fullMessage += message.getMessageBody(); // 获取短信内容
    }
    textView.setText("address; " + address + ", message: " + fullMessage);
    abortBroadcast();
  }
} 

// 注册接收广播
IntentFilter intentFilter1 = new IntentFilter();
intentFilter1.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY);
intentFilter1.addAction("android.provider.Telephony.SMS_RECEIVED");
messageReceiver = new MessageReceiver();
registerReceiver(messageReceiver, intentFilter1);

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

// 发送短信
public void send(View view) {
  SmsManager smsManager = SmsManager.getDefault();
  String destinationAddress = "15527100207";
  String text = "我爱你！";

  Intent intent1 = new Intent(SENT_SMS_ACTION);
  PendingIntent sentIntent = PendingIntent.getBroadcast(this, 0, intent1, 0);
  Intent intent2 = new Intent(DELIVERY_SMS_ACTION);
  PendingIntent deliveryIntent = PendingIntent.getBroadcast(this, 0, intent2, 0);
  smsManager.sendTextMessage(destinationAddress, null, text, sentIntent, deliveryIntent); // aidl服务,进程间的通信
}

public void sendTextMessage(String destinationAddress, String scAddress, String text,PendingIntent sentIntent, PendingIntent deliveryIntent)
destinationAddress: // 目的地，也就是对方的手机号
scAddress：     // 服务中心地址，为空的话就是默认的SMSC
text：        // 发送消息的具体内容
sentIntent：     // 当消息成功或者失败发送时，就发起这个广播
deliveryIntent：   // 当消息到达目的地时，就发起这个广播

// 发送短信的状态广播
class MessageBroadcast extends BroadcastReceiver {
  @Override
  public void onReceive(Context context, Intent intent) {
    // 一个10位数的号码发送，也能成功，但是对方没有接收短信。
    if (getResultCode() == RESULT_OK) {
      Toast.makeText(MainActivity.this, "发送成功!", Toast.LENGTH_SHORT).show();
    } else {
      Toast.makeText(MainActivity.this, "发送失败!", Toast.LENGTH_SHORT).show();
    }
  }
} 

// 当消息被传递给收件人时 
class DeliveryBroadcast extends BroadcastReceiver {
  @Override
  public void onReceive(Context context, Intent intent) {
    Toast.makeText(MainActivity.this, "对方接收短信成功!", Toast.LENGTH_SHORT).show();
  }
}
