我有一个可以工作的 SMS 接收器，但是当我尝试使用以下方法加载另一个类时：

Intent intent = new Intent(SMSReceiver.this, SMSNotifier.class);  
startActivityForResult(intent, 0);

我收到此错误：

构造函数 Intent(SMSReceiver, Class) 未定义

对于第一行和：

方法 startActivityForResult(Intent, int) 未定义 SMSReceiver 类型

第二行

我真的很感激一些关于出了什么问题的建议。

package com.prototype.messages;

        Bundle bundle = intent.getExtras();          
        SmsMessage[] msgs = null;  
        String str = "";              
        if (bundle != null) {  
            Object[] pdus = (Object[]) bundle.get("pdus");  
            msgs = new SmsMessage[pdus.length];              
            for (int i=0; i<msgs.length; i++){

SMSReceiver不是一项活动。只有活动可以使用startActivityForResult()，并且只有Contexts（的父类Activity）可以用于创建Intent使用您选择的构造函数。
