Android 按下Arduino上的按钮时拨打电话

嗨，我正在尝试合并两个项目 1.这告诉我arduino的按钮按下了 2.在android上打个电话

我要做的是按下arduino上的按钮打电话。。 但是没有运气：(

您的

call（）

函数已在活动中声明，但您正试图在

ButtonView

类中访问它。请尝试将其移动到

ButtonView

（复制和粘贴）.

发生了什么？你的应用程序正在崩溃，你是否遇到编译错误，或者它只是不工作？如果是第一个，请发布你的日志。我在调用中遇到错误（）；调用（）对于tipe输入操作未定义它在第一个“如果”之后的按钮->public void run（）->中这里有完整的项目，这是因为您需要a/将调用放入ButtonView或b/获取您的活动上下文以访问调用函数i复制“code”私有void call（）{try{callIntent=new Intent（Intent.ACTION_call）；callIntent.setData（Uri.parse（“tel:048598077”）；startActivity（callIntent）；}catch（ActivityNotFoundException activityException）{Log.e（“拨号示例”、“呼叫失败”、“activityException”）；}到ButtonView，现在它告诉我“方法StartActivity在button视图中未定义”如果我创建了一个写什么的方法？或者我应该做其他事情吗？您不能从

视图

上下文启动

活动

，因为函数

startActivity（）

是在

活动

中定义的。解决方法很简单，下面将详细说明：
