Question

我在eclips写了发送和接收短信。我设置了特殊的电话号码。当短信收到特殊号码，短信进入程序和其他短信，进入手机收件箱。现在，当收到特殊号码的短信时，程序打开但不显示在程序中。请帮帮我。

receive.java

public class SmsReceiver extends BroadcastReceiver {
    public String str = "";

    @Override
    public void onReceive(Context context, Intent intent) {
        // ---get the SMS message passed in---

        Bundle bundle = intent.getExtras();
        SmsMessage[] msgs = null;

        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]);

                //for get sms from special number===============================
                String msg_from = msgs[i].getOriginatingAddress();
                Log.v("msg_from >>",msg_from);     
                if(msg_from.equals("09124502715"))
                {
                    //===============================
                str += "SMS from " + msgs[i].getOriginatingAddress();
                str += " :";
                str += msgs[i].getMessageBody().toString();
                str += "\n";
                }

            }
            // ---display the new SMS message---
            // Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
            Intent act = new Intent(context, MainActivity.class);
            act.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            act.putExtra("message", str);
            context.startActivity(act);

Answer 1

您是否将您使用的活动添加到manifest.xml？不这样做可能会导致空指针异常，在任何情况下都会超过一些logcat错误......

Answer 2

SmsMessage.getOriginatingAddress - 以字符串形式返回此SMS消息的原始地址（发送方），如果不可用则返回null。如果使用的是sendsms（）方法，则会将发送方地址作为空值传递。 sms.sendTextMessage（phoneNumber，null，message，sentPI，deliveredPI）;

你也应该推荐abortBroadcast（）方法。因为这会导致一些不愉快的事情。

为什么不在程序中显示收到的短信？
