我的代码：

 public class MainActivity extends Activity {   



      public static class SmsReceiver extends BroadcastReceiver{


        int i;
        String body ;
        String number ;
        String no = "15555215554";

                @Override
                public void onReceive(Context context, Intent intent) {
                    // 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];
                        for (i=0; i<msgs.length; i++)
                        {
                            Toast.makeText(context, +i, Toast.LENGTH_SHORT).show();
                            msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);

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

                            str += msgs[i].getMessageBody().toString();
                            str += "\n";
                            Toast.makeText(context, str, Toast.LENGTH_SHORT).show();


                            }
                        }                     

                }

    }
    }





    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

Answer 1

忽略这类问题。请不要将Receiver类用作内部类。使它成为单独的类并在Manifest中注册。并有适当的意图过滤器将为您的目标服务。

Answer 2

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

您想要使用this one，如下所示：

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

Nyou正在使用的makeText()版本需要一个字符串资源ID。

广播接收器作为内部类
