第一步：建立 layout1.axml 來展示列表詳細內容
<?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 新增 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：建立 SimpleAdapter 資料介面卡
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); //建立資料介面卡 SimpleAdapter content = new SimpleAdapter( this, GetData(), Resource.Layout.layout1, new string[] { "img", "name" }, new int[] { Resource.Id.img, Resource.Id.name }); //把資料繫結到list_member 這個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(引數名字,引數值) JavaDictionary<string, Object> map; map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊1"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊2"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊3"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊4"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊5"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊6"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊7"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊8"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊1"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊2"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊3"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊4"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊5"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊6"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊7"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); map = new JavaDictionary<string, Object>(); map.Add("name", "我的資訊8"); map.Add("img", Resource.Drawable.icon_myinfo); list.Add(map); return list; } } }
