Xamarin.Android 使用 SimpleAdapter 打造 ListView 万能适配器 _Xamarin.Android

别裁伪体亲风雅，转益多师是汝师。这篇文章主要讲述Xamarin.Android 使用 SimpleAdapter 打造 ListView 万能适配器相关的知识，希望能为你提供帮助。
第一步：创建 layout1.axml 来展示列表详细内容

< ?xml version="1.0" encoding="utf-8"?> < LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="8dp"> < ImageView android:id="@+id/img" android:layout_width="26dp" android:layout_height="26dp" android:layout_marginLeft="20dp" /> < TextView android:id="@+id/name" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="center_vertical" android:layout_marginLeft="10dp" android:textColor="#000000"/> < /LinearLayout>

第二步：在 Main.axml 添加 ListView

< ?xml version="1.0" encoding="utf-8"?> < LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> < HorizontalScrollView android:layout_width="match_parent" android:layout_height="match_parent"> < LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:background="#ffffff"> < ListView android:id="@+id/left_menu" android:layout_width="match_parent" android:layout_height="match_parent" android:divider="@null" android:text="DrawerLayout" /> < /LinearLayout> < /HorizontalScrollView> < /LinearLayout>

第三步：创建 SimpleAdapter 数据适配器

using Android.App; using Android.Widget; using Android.OS; using System.Collections.Generic; using System; using Android.Runtime; namespace SimpleAdapterDemo { [Activity(Label = "SimpleAdapterDemo", MainLauncher = true)] public class MainActivity : Activity { private ListView listview_leftMenu; protected override void OnCreate(Bundle savedInstanceState) { base.OnCreate(savedInstanceState); // Set our view from the "main" layout resource SetContentView(Resource.Layout.Main); listview_leftMenu = FindViewById< ListView> (Resource.Id.left_menu); //创建数据适配器 SimpleAdapter content = new SimpleAdapter( this, GetData(), Resource.Layout.layout1, new string[] { "img", "name" }, new int[] { Resource.Id.img, Resource.Id.name }); //把数据绑定到list_member 这个listview上listview_leftMenu.Adapter = content; listview_leftMenu.ItemClick += (s, e) => { Listview_leftMenu_ItemClick(e.Position); }; }private void Listview_leftMenu_ItemClick(int position) { Toast.MakeText(this, list[position]["name"].ToString(), ToastLength.Short).Show(); }IList< IDictionary< string, Object> > list = new javaList< IDictionary< string, Object> > (); private IList< IDictionary< string, Object> > GetData() { //map.put(参数名字,参数值)JavaDictionary< string, Object> map; map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息1"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息2"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息3"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息4"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息5"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息6"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息7"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息8"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息1"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息2"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息3"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息4"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息5"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息6"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息7"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary< string, Object> (); map.Add("name", "我的信息8"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); return list; } } }
