[英]How to send an email in Xamarin Android using variables of radio buttons?
嗨，我正在做一个应用程序，它有一个“发送电子邮件”按钮。
因此，在该按钮上，我想发送一些将接收某些RadioGroups值的变量。
我做了一些“ If / ElseIf”操作，以允许用户仅选择一个RadioGroup，然后向将要使用微调器的人发送一封电子邮件（到目前为止效果很好）。
但是，当我单击“发送电子邮件按钮” Idk时尝试选择2个或更多RadioGroups时，该程序只是传递上次单击按钮的值，而不传递我选择的所有值，如下图所示电子邮件画面
那么如何在电子邮件中发送2个或更多变量
这是代码

catch (Java.Lang.Exception ex)

根据您的代码，我认为您尝试使用Button的click事件来获取每个RadioGroup选中RadioButton ，然后例如，如果布局是这样的：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RadioGroup
android:id="@+id/group1"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<TextView
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="This is group 1" />
<RadioButton
android:id="@+id/radio11"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="radio1" />
<RadioButton
android:id="@+id/radio12"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="radio2" />
</RadioGroup>
<RadioGroup
android:id="@+id/group2"
android:layout_height="wrap_content"
android:layout_width="match_parent">
<TextView
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="This is group 2" />
<RadioButton
android:id="@+id/radio21"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="radio3" />
<RadioButton
android:id="@+id/radio22"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="radio4" />
</RadioGroup>
<Button
android:id="@+id/checkBtn"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:text="get checked radiobutton" />
</LinearLayout>
您可以这样编写：
private string result;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
// Create your application here
SetContentView(Resource.Layout.layout1);
RadioGroup group1 = FindViewById<RadioGroup>(Resource.Id.group1);
RadioGroup group2 = FindViewById<RadioGroup>(Resource.Id.group2);
Button enviar = FindViewById<Button>(Resource.Id.checkBtn);
enviar.Click += (sender, e) =>
{
var itemOfGroup1 = group1.CheckedRadioButtonId;
var itemOfGroup2 = group2.CheckedRadioButtonId;
if (itemOfGroup1 != -1) //if one of the group radio is checked
{
var radiobtn1 = FindViewById<RadioButton>(itemOfGroup1);
result = "group1:" + radiobtn1.Text;
}
if (itemOfGroup2 != -1)
{
var radiobtn2 = FindViewById<RadioButton>(itemOfGroup2);
result = result + " group2:" + radiobtn2.Text;
}
//if there're more groups, codes are the same, for example: result = result + "group3: "+ radiaobtn3.Text;
var email = new Intent(Android.Content.Intent.ActionSend);
email.PutExtra("message", result);
//more email relative codes goes here
};
}
您不需要那种复杂的逻辑，并且我只用了一个简单的字符串就可以将所有选中的RadioButton Text合并到变量值result ，您应该能够更改此字符串的格式。 祝好运。
