        String str = "";

            str += " :";
            str += msgs[i].getMessageBody().toString();
            str += "\n";        
        }
        //---display the new SMS message---
        Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
    }                       
}

这是接收我发送的短信的代码..但我可以将它显示到收件箱..我正在尝试解密它并将其发送到收件箱..或者至少利用收件箱消息并解密它......所以是在收到收件箱的消息之前或之后有任何方法可以访问文本正文。
