Question

我发现许多类似的问题，我见过的大多数是Java，问题是我不知道如何将Java代码转换为C＃Xamarin。

以下是我找到的代码：from here

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="testApp" ng-controller="testCtrl">
 
 <div >
      <form  name="form">
        
        <input type="text" name="name" ng-model = "data.name"  required>    
           
        <input type="text" name="age" ng-model = "data.age" required>
        
        <input type="button" value="reset" ng-click="reset()">
      </form>   
   </div>
  
</div>

我特别提到这一行：

   month.setOnItemSelectedListener(new OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> parent, View view,
                int pos, long id) {
            // TODO Auto-generated method stub
            List<String> s = Arrays.asList(getResources().getStringArray(R.array.item_day));
            if (pos == 0 || pos == 2 || pos == 4 || pos == 8 || pos == 9
                    || pos == 11) {
                ArrayAdapter<String> dayadapter = new  ArrayAdapter<String>(Latlondemo.this, android.R.layout.simple_spinner_item,s);
                day.setAdapter(dayadapter);
            } else if (pos == 1) {
                s = s.subList(0,28);                    
                ArrayAdapter<String> dayadapter = new  ArrayAdapter<String>(Latlondemo.this, android.R.layout.simple_spinner_item,s);
                day.setAdapter(dayadapter);
            } else {
                s = s.subList(0,30);                    
                ArrayAdapter<String> dayadapter = new  ArrayAdapter<String>(Latlondemo.this, android.R.layout.simple_spinner_item,s);
                day.setAdapter(dayadapter);
            }
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

它的C＃对应物是什么？

到目前为止，这是我的代码：

List<String> s = Arrays.asList(getResources().getStringArray(R.array.item_day));

字符串资源：

        spinner1 = FindViewById<Spinner>(Resource.Id.spinner1);
        spinner2 = FindViewById<Spinner>(Resource.Id.spinner2);

        var adapter1 = ArrayAdapter.CreateFromResource(
                this, Resource.Array.building_array, Android.Resource.Layout.SimpleSpinnerItem);
        var adapter2 = ArrayAdapter.CreateFromResource(
                this, Resource.Array.level_array, Android.Resource.Layout.SimpleSpinnerItem);

        adapter1.SetDropDownViewResource(Android.Resource.Layout.SimpleSpinnerDropDownItem);
        adapter2.SetDropDownViewResource(Android.Resource.Layout.SimpleSpinnerDropDownItem);
        spinner1.Adapter = adapter1;
        spinner2.Adapter = adapter2;
        spinner1.ItemClick += (sender, e) => {

        // code here

        };

C＃对应物是

var arr = Resources.GetStringArray(Resource.Array.building_array);

这在Android上下文中有效，例如您的活动，因为Resources是其中的属性。

如果您希望它为List<sting>，只需在呼叫中添加.ToList()（需要：using System.Linq;）。
