我想制作一个应用程序，它在 user1 中向 user2 发送带有一些特定文本的消息。用户 2 自动通过短信将位置发送给用户 1，但不应通知用户 2。下面的 BroadcastReceiver 收到文本时显示“知道了”.. 收到消息“UPDATE”时如何进行自动回复
IncomingSMSReciever.java
public class IncomingSMSReceiver extends BroadcastReceiver{
private static final String SMS_RECEIVED =
"android.provider.Telephony.SMS_RECEIVED";
@Override
public void onReceive(Context _context, Intent _intent) {
if (_intent.getAction().equals(SMS_RECEIVED)) {
Bundle bundle = _intent.getExtras();
if (bundle != null) {
Object[] pdus = (Object[]) bundle.get("pdus");
SmsMessage[] messages = new SmsMessage[pdus.length];
for (int i = 0; i < pdus.length; i++)
messages[i] = SmsMessage
.createFromPdu((byte[]) pdus[i]);
for (SmsMessage message : messages) {
String strPhoneNo = message.getOriginatingAddress();
String msg = message.getMessageBody();
if (msg.startsWith("UPDATE"))
{
Toast.makeText(_context, "Whats up!!", Toast.LENGTH_LONG).show();
// this stops notifications to others
this.abortBroadcast();
// do what you want
}
}
}
}
}
}
SvrSmsListener.java
public class SrvSmsListener extends Service
{
IncomingSMSReceiver SMSReceiver=new IncomingSMSReceiver();
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
public void onCreate() {
final String SMS_RECEIVED = "android.provider.Telephony.SMS_RECEIVED";
IntentFilter filter = new IntentFilter(SMS_RECEIVED);
BroadcastReceiver receiver = SMSReceiver;
registerReceiver(receiver, filter);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
return super.onStartCommand(intent, flags, startId);
}
@Override
public void onDestroy() {
if (SMSReceiver != null)
{
unregisterReceiver(SMSReceiver);
}
}
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
}
}
