Question

我的目标是创建一个短信服务器，能够通过发送短信向请求的用户发送短信...我创建了第一个广播接收器来接收短信并获得发送者号码和消息体。与那个身体（滚动否）另一个活动与该卷没有导致该人的标记.. 起初我将消息体从broadcastreceiver传递给活动.. 这是我的BroadcastReceiver代码：

public class IncomingSms extends BroadcastReceiver{


@Override
public void onReceive(Context arg0, Intent arg1) {
    // TODO Auto-generated method stub

    if(arg1.getAction().equals("android.provider.Telephony.SMS_RECEIVED")) {
        Bundle bundle = arg1.getExtras();
        SmsMessage[] msgs = null;
        String msg_from;
        String msgBody;
        if(bundle!=null) {
            try {
                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]);
                    msg_from = msgs[i].getOriginatingAddress();
                    msgBody = msgs[i].getMessageBody();
                    Toast.makeText(arg0, "SenderNum :" + msg_from + "msg :" + msgBody,    Toast.LENGTH_LONG).show();
                    Intent in = new Intent("SmsMessage.intent.MAIN");
                    in.putExtra("get_msg", msgBody);
                    arg0.sendBroadcast(in);
                }
                msg_from = msgs[0].getOriginatingAddress();
                String msg = arg1.getStringExtra("string");
                Toast.makeText(arg0, "Sms sent", Toast.LENGTH_LONG).show();
                SmsManager sms = SmsManager.getDefault();
                sms.sendTextMessage(msg_from, null, msg, null, null);

            } catch(Exception e) {
                Log.d("Exception caught", e.getMessage());
            }
        }
    }
    }
    }`

之后，将该消息体与现有的roll no's数据库进行比较，如果找到则将此字符串传递给broadcastreceiver，以便向用户发送短信... 这是我的活动代码：

public class MyApp extends Activity implements OnClickListener
{
    EditText editRollno,editName,editMarks;
    Button btnAdd,btnDelete,btnModify,btnView,btnViewAll,btnShowInfo;
SQLiteDatabase db;

String s;
String s1,s2,s3;
String str,str1;
private BroadcastReceiver bd;
IncomingSms is = new IncomingSms();
String pNumber;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    registerReceiver(is,new IntentFilter("MyReceiver"));
    Intent i = new Intent("MyReceiver");
    i.putExtra("string", s3);
    sendBroadcast(i);
    editRollno=(EditText)findViewById(R.id.editRollno);
    editName=(EditText)findViewById(R.id.editName);
    editMarks=(EditText)findViewById(R.id.editMarks);
    btnAdd=(Button)findViewById(R.id.btnAdd);
    btnDelete=(Button)findViewById(R.id.btnDelete);
    btnModify=(Button)findViewById(R.id.btnModify);
    btnView=(Button)findViewById(R.id.btnView);
    btnViewAll=(Button)findViewById(R.id.btnViewAll);
    btnShowInfo=(Button)findViewById(R.id.btnShowInfo);
    btnAdd.setOnClickListener(this);
    btnDelete.setOnClickListener(this);
    btnModify.setOnClickListener(this);
    btnView.setOnClickListener(this);
    btnViewAll.setOnClickListener(this);
    btnShowInfo.setOnClickListener(this);
    db=openOrCreateDatabase("StudentDB", Context.MODE_WORLD_READABLE, null);
    db.execSQL("CREATE TABLE IF NOT EXISTS student(rollno VARCHAR,name VARCHAR,marks VARCHAR);");



}
public void onClick(View view)
{
    if(view==btnAdd)

            return;
        }
        Cursor c=db.rawQuery("SELECT * FROM student WHERE rollno='"+editRollno.getText()+"'",     null);
        if(c.moveToFirst())

    // TODO Auto-generated method stub
    super.onPause();
    this.unregisterReceiver(this.bd);
}
@Override
protected void onDestroy() {
    // TODO Auto-generated method stub

    unregisterReceiver(is);
    super.onDestroy();
}


}

执行此操作后，它接收到短信但没有发送短信但它发送短信发送短信...我无法理解..plzzz帮助我...谢谢提前..

试试这个：

msg_from = msgs[0].getOriginatingAddress();
String msg = arg1.getStringExtra("string");
PendingIntent sentPI = PendingIntent.getBroadcast(this, 0,new Intent(SENT), 0); // <-- add this
SmsManager sms = SmsManager.getDefault();
sms.sendTextMessage(msg_from, null, msg, sentPI, null); //<-- Add this
Toast.makeText(arg0, "Sms sent", Toast.LENGTH_LONG).show(); //<-- move it here

android sms发送到收到的号码
