Android使用电子邮件地址列表发送电子邮件

我已经创建了一个应用程序，其中内置了一个表单，目前正在发送到一个预先确定的电子邮件地址。有没有一种方法可以根据用户在表单中按的内容自动添加电子邮件地址，而不是根据发送到的电子邮件地址创建十几个版本的应用程序？i、 e单击滚动条中的美国，它会自动将美国电子邮件地址放入要发送的电子邮件中

如果有的话，有没有任何人可以给我指点的教程或例子

我已在下面附上我的代码：

非常感谢

您可以通过使用键值对实现微调器来实现

valueTextView=（TextView）findviewbyd（R.id.selected）；
微调器s=（微调器）findViewById（R.id.Spinner）；
最终MyData项目[]=新MyData[3]；
项目[0]=新的MyData（“美国”us@abc.com" );
第[1]项=新的MyData（“印度”）india@abc.com" );
项目[2]=新的MyData（“英国”uk@abc.com" );
ArrayAdapter=新的ArrayAdapter此，android.R.layout.simple\u微调器\u项，项）；
setDropDownViewResource（android.R.layout.simple\u微调器\u下拉菜单\u项）；
s、 设置适配器（适配器）；
s、 setOnItemSelectedListener（新的AdapterView.OnItemSelectedListener（）
{
已选择公共视图（AdapterView父视图、视图视图、整型位置、长id）
{
MyData d=项目[位置]；
valueTextView.setText（d.getValue（））；
}
未选择公共无效（AdapterView父级）
{
}
}
);
类MyData{
公共MyData（字符串微调器文本、字符串值）{
this.spinnerText=spinnerText；
这个值=值；
}
公共字符串getSpinnerText（）{
返回喷丝头文本；
}
公共字符串getValue（）{
返回值；
}
公共字符串toString（）{
返回喷丝头文本；
}
字符串喷丝板文本；
字符串值；
}
