    }

推荐答案

在android中，使用自定义渲染器，您可以使用以下代码将搜索图标放置在搜索栏的右侧:

In android, with a custom renderer, you can use the following code to place the search icon at the right side of your search bar:

    protected override void OnElementChanged(ElementChangedEventArgs<SearchBar> e)
    {
        base.OnElementChanged(e);
        if (e.NewElement != null)
        {
            var searchView = base.Control as SearchView;

            //Get the Id for your search icon
            int searchIconId = Context.Resources.GetIdentifier("android:id/search_mag_icon", null, null);
            ImageView searchViewIcon = (ImageView)searchView.FindViewById<ImageView>(searchIconId);
            ViewGroup linearLayoutSearchView = (ViewGroup)searchViewIcon.Parent;

            searchViewIcon.SetAdjustViewBounds(true);

            //Remove the search icon from the view group and add it once again to place it at the end of the view group elements
            linearLayoutSearchView.RemoveView(searchViewIcon);
            linearLayoutSearchView.AddView(searchViewIcon);
        }
    }

在上述实现中，我只是从搜索栏视图组中删除了搜索图标，然后将其再次添加到同一视图组中.这样通常会将第一个孩子放到最后一个孩子，因此将搜索图标放在最后.

In the above implementation, I simply removed the search icon from the search bar view group and then added it again to the same view group. This placed the normally first child to the last child, thus placing the search icon at the end.
