Android 捕获Searchview清除按钮事件

我试图在android项目的搜索视图中捕获clear button事件：

SearchView _search = FindViewById<SearchView>(Resource.Id.publicSearchview);
_search.QueryTextSubmit += SearchBtn_Click;
ImageView _closeBtn = FindViewById<ImageView>(Resource.Id.search_close_btn);
_closeBtn.Click += CloseBtn_Click;

SearchView\u search=findviewbyd（Resource.Id.publicSearchview）；
_search.querytexsubmit+=SearchBtn\u单击；
ImageView\u closeBtn=findviewbyd（Resource.Id.search\u closeBtn）；
_closeBtn.Click+=closeBtn\u Click；

但是_closeBtn总是空的。有什么建议吗

    <SearchView
        android:minWidth="25px"
        android:minHeight="25px"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/publicSearchview" />

假设

SearchView

未设置为icon'fy，这将起作用：

var _search = FindViewById<SearchView>(Resource.Id.searchView1);
int searchCloseButtonId = _search.Context.Resources.GetIdentifier("android:id/search_close_btn", null, null);
var _closeBtn = FindViewById<ImageView>(searchCloseButtonId);
_closeBtn.Click += (object sender, EventArgs e) => 
{ 
    Toast.MakeText(this, "Close Click", ToastLength.Long).Show();
};

var\u search=findviewbyd（Resource.Id.searchView1）；
int searchCloseButtonId=\u search.Context.Resources.GetIdentifier（“android:id/search\u close\u btn”，null，null）；
var_closeBtn=findviewbyd（searchCloseButtonId）；
_closeBtn.单击+=（对象发送者，事件参数e）=>
{ 
Toast.MakeText（这是“Close Click”，ToastLength.Long）.Show（）；
};
