我正在创建的应用程序中有一个部分允许用户将信息输入到八个不同的TextField中。那些字段是：
现在，当这些信息完成并且用户点击提交按钮时，我要么想要在点击按钮之后直接将信息发送到我的个人电子邮件地址，要么存储要在稍后查看的信息。我对Android开发比较陌生，但是，我认为我应该在按下按钮时调用的方法中执行以下操作：
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/chosen/1.0/chosen.jquery.min.js"></script>
<script src="https://rawgit.com/leocaseiro/angular-chosen/master/dist/angular-chosen.min.js">
</script>
<link data-require="chosen@*" data-semver="1.0.0" rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/chosen/1.0/chosen.min.css" />
<div ng-app="myApp" ng-controller="MainCtrl">
<select chosen multiple ng-model="state" ng-options="s.id as s.title for s in states">
<option value=""></option>
</select>
</div>我搜索并搜索过，找不到任何我想要完成的事情。有可能将信息直接发送到我的电子邮件吗？或者我是否需要以某种方式存储它以供以后查看。到目前为止我的Java文件：
final EditText moverName = (EditText)findViewById(R.id.nameRegistration);
String name = regName.getText().toString();
提前致谢！

在您的情况下，您有两个发送电子邮件的选项：
使用应用程序发送电子邮件：在这种情况下，您只能启动电子邮件应用程序，其中包含您要在电子邮件正文中预先填充的所有信息。但是，在这种情况下，你必须再次按下最后的“发送”。您可以在此处查看详细信息 - How to open Email program via Intents (but only an Email program)
与MailChimp，sendgrid等任何电子邮件提供商集成，并直接通过您的应用或后端进行API调用。

我已经用这个解决方案复制了你的问题，它没有经过测试，但我相信它会为你指明一个好的方向。
要在您的应用中保存，您可以执行此操作
