Xamarin SearchView 用法摘记

与Windows开发不同，这个控件的事件比较难找，费了半天劲才知道应该用哪个事件。核心代码如下：

    public class MainActivity : Activity
    {
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            // Set our view from the "main" layout resource
            SetContentView (Resource.Layout.Main);

            var searchView1 = FindViewById<SearchView>(Resource.Id.searchView1);
            searchView1.SubmitButtonEnabled = true;
            searchView1.QueryTextSubmit += SearchView1_QueryTextSubmit;
        }

        private void SearchView1_QueryTextSubmit(object sender, SearchView.QueryTextSubmitEventArgs e)
        {
            var text = e.Query;
        }
    }
