制作一个短信应用程序，到目前为止进展顺利，但昨晚在尝试实施新活动后遇到了问题。
当我单击布局上的“发送”按钮时，它会发送 SMS，并触发 Toast 通知我已发送 SMS。直到我尝试将 onClick 属性添加到 XML 导致开始新活动的意图之前，这一直运行良好......这就是开始发生的时候：
它没有启动我创建的新活动，而是将我发送到手机随附的默认“消息”应用程序的“新消息”布局/活动。我不明白这一点，所以拿走了（除非我一遍又一遍地错过了一些东西）我在工作时所做的一切改变。
YET：当我单击此按钮时，它仍在将我发送到那个新消息活动......
有人可以告诉我在我的代码中我告诉应用程序启动该活动的位置吗？谢谢！
