一、简介
1、展示全景图的方式
有以下展示全景图的办法：
（1）利用地理坐标展示全景图。
（2）利用全景图ID展示全景图。
（3）利用墨卡托坐标展示全景图。
（4）利用地图POI ID展示全景图。
通过以上方式，就可以使用百度提供的全景图展示服务了。
2、坐标转换
为了更方便的获取全景图，SDK还提供了坐标转化工具，利用CoordinateConverter 工具中的方法可以很方便进行坐标转换。
3、全景图控制
用户可以利用手势或者接口对全景图实现丰富的操作。手势操作包括：双指缩放、单指拖动、点击邻接街景箭头。
接口操作包括：改变当前全景图的俯仰角，偏航角以及缩放级别，设置是否显示邻接箭头（如果有邻接街景的情况）。
4、全景图覆盖物
百度SDK支持在全景图内绘制开发者自定义的标注，同时针对所绘制的标注，还支持相应的点击事件响应。目前支持图片和文本两种覆盖物。
2.0.0版本支持设置覆盖物的高度，通过SetPitchHeight(float height)设置覆盖物距离地面的高度(单位m)。
5、内景相册
2.2版本将内景相册的实现封装为内景相册插件，如需植入内景，只需导入内景相册插件包(IndoorscapeAlbumPlugin.jar)，并通过如下一行代码即可快速完成显示内景相册。
二、运行截图
本示例的运行截图如下：
三、设计步骤
1、添加布局文件
需要在layout文件夹下添加的布局文件有（代码太多，不再粘贴到此处）：
demo20_panodemo.xml
demo20_panodemo_coordinate.xml
demo20_panodemo_list_item.xml
demo20_panodemo_main.xml
2、添加Demo20PanoActivity.cs文件
在SrcSdkDemos文件夹下添加该文件，然后将其内容改为下面的代码：
using Android.App;
using Android.Content;
using Android.OS;
using Android.Views;
using Android.Widget;
namespace BdMapV371Demos.SrcSdkDemos
{
[Activity(Label = "@string/demo_name_panorama")]
public class Demo20PanoActivity : Activity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.demo20_panodemo); ListView mListView = FindViewById<ListView>(Resource.Id.panodemo_list);
mListView.Adapter = new DemoListAdapter(this);
mListView.ItemClick += (s, e) =>
{
Intent intent = new Intent(this, panoDemos[e.Position].demoClass.GetType());
intent.PutExtra("type", (int)panoDemos[e.Position].type);
StartActivity(intent);
};
} private static readonly DemoInfo<Activity>[] panoDemos =
{
new DemoInfo<Activity>(PanoDemoType.PID, Resource.String.demo_title_panorama,
Resource.String.demo_desc_panorama0, new Demo20PanoMain()),

new DemoInfo<Activity>(PanoDemoType.CoordinateConverter, Resource.String.demo_title_panorama,
Resource.String.demo_desc_panorama6, new Demo20PanoCoordinate()),
new DemoInfo<Activity>(PanoDemoType.Other, Resource.String.demo_title_panorama,
Resource.String.demo_desc_panorama7, new Demo20PanoMain())
}; private class DemoListAdapter : BaseAdapter
{
Demo20PanoActivity demo20;
public DemoListAdapter(Demo20PanoActivity demo20) : base()
{
this.demo20 = demo20;
} public override View GetView(int index, View convertView, ViewGroup parent)
{
convertView = View.Inflate(demo20, Resource.Layout.demo20_panodemo_list_item, null);
TextView title = convertView.FindViewById<TextView>(Resource.Id.item_title);
TextView desc = convertView.FindViewById<TextView>(Resource.Id.item_desc); title.SetText(panoDemos[index].title);
desc.SetText(panoDemos[index].desc);
return convertView;
} public override int Count
{
get { return panoDemos.Length; }
} public override Java.Lang.Object GetItem(int index)
{
return panoDemos[index];
} public override long GetItemId(int id)
{
return id;
}
} private class DemoInfo<T> : Java.Lang.Object where T : Activity
{
public readonly int title;
public readonly int desc;
public readonly PanoDemoType type;
public readonly T demoClass;
public DemoInfo(PanoDemoType type, int title, int desc, T demoClass)
{
this.type = type;
this.title = title;
this.desc = desc;
this.demoClass = demoClass;
}
}
} public enum PanoDemoType
{
/// <summary>PID方式</summary>

3、Demo20PanoMain.cs文件

5、修改MainActivity.cs文件
在MainActivity.cs文件的demos字段定义中，去掉【示例20】下面的注释。
运行观察效果。
