我的应用程序是用户发送祝福消息的地方。它有Spinner，其中包含配方＆＃39;名字和他们的硬编码。我创建了一个Toast消息说＆＃34; SMS已成功发送＆＃34;。但我意识到我需要在Toast消息中包含某个食谱名称，以确认消息是否已发送给配方。
我已尝试过任何我知道的Toast消息，试图包含食谱的名称，但是当我运行应用程序时，我收到错误并且Toast消息失败。我将发布短信应用的完整代码。

{I}尝试做的Toast.makeText(getBaseContext(), "SMS is sent to" +contact_name successfully",
Toast.LENGTH_SHORT).show();包含配方名称。
如果有人知道如何做这个吐司，我会很感激=）。很抱歉要求一个简单的帮助，但我尝试了3种不同的方式来做这种Toast消息。
提前致谢！ =）
答案 0 :(得分：0)
我已经想出如何做这个Toast。
您在public void onReceive() private void sendSMS()
Toast.makeText(getBaseContext(), "SMS is sent to " +sendTo.getSelectedItem()+ " successfully.",
Toast.LENGTH_SHORT).show();
getSelectedItem()正在从Spinner获取所选项目。如果您使用的是EditText或TextView，只需将getSelectedItem()替换为getText()
：D，那些与我有类似问题的人，可以尝试这个答案，并希望它能解决他们类似的问题。 ：d
