Android 使用电子邮件地址列表发送电子邮件

Question

我创建了一个内置表单的应用程序，该表单目前正在发送到预先确定的电子邮件地址。与其根据将其发送到哪个电子邮件地址来创建十几个版本的应用程序，有没有一种方法可以根据人们在表单中按的内容自动添加电子邮件地址？即在滚动条中点击美国，它会自动将美国邮箱地址放入邮件中发送？

如果有的话，是否有任何人可以指点我的教程或示例？

我在下面附上了我的代码：

您可以通过使用键值对实现 Spinner 来实现

  valueTextView = (TextView)findViewById( R.id.selected );
   Spinner s = (Spinner)findViewById(R.id.spinner);
    final MyData items[] = new MyData[3];
    items[0] = new MyData( "US","us@abc.com" );
    items[1] = new MyData( "INDIA","india@abc.com" );
    items[2] = new MyData( "UK","uk@abc.com" );
    ArrayAdapter<MyData> adapter = new ArrayAdapter<MyData>this,android.R.layout.simple_spinner_item,items);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    s.setAdapter(adapter);
    s.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() 
     {
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) 
            {
                MyData d = items[position];
                valueTextView.setText( d.getValue() );
            }

            public void onNothingSelected(AdapterView<?> parent) 
            {
            }
        }
    );


   class MyData {
    public MyData( String spinnerText, String value ) {
        this.spinnerText = spinnerText;
        this.value = value;
    }

    public String getSpinnerText() {
        return spinnerText;
    }

    public String getValue() {
        return value;
    }

    public String toString() {
        return spinnerText;
    }

    String spinnerText;
    String value;
}
