我的代码：

 public class MainActivity extends Activity {   



      public static class SmsReceiver extends BroadcastReceiver{


        int i;
        String body ;
        String number ;

                    // TODO Auto-generated method stub
                    Bundle bundle = intent.getExtras();
                    SmsMessage[] msgs = null;
                    String str = "";
                    if (bundle != null)
                    {
                        // Retrieve the SMS.
                        Object[] pdus = (Object[]) bundle.get("pdus");
                        msgs = new SmsMessage[pdus.length];

                            msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);

                            if(msgs[i].getOriginatingAddress().equals(no))

                            Toast.makeText(context, str, Toast.LENGTH_SHORT).show();


                            }
                        }                     

                }

    }
    }





    @Override

忽略这类问题。请不要将 Receiver 类用作内部类。使其成为单独的类并在清单中注册。并使用适当的意图过滤器将服务于您的目标。

根据您更新的问题，问题是您使用了错误的Toast.makeText()方法。

您想按如下方式使用它：

Toast.makeText(context, msgs[i], Toast.LENGTH_SHORT).show();

makeText()Nyou 使用的版本需要一个字符串资源 ID。
