3.3 Example 3--Usage of MapFragment

1. Introduction

TextureMapFragment: used to display map fragments.

2. Example 3--Demo03MapFragment.cs

File name: Demo02MapFragment.cs

Introduction: Introducing the use of maps under the Fragment framework

Details: Introduce how to add a TextureMapFragment control under the Fragment framework;

1. Running screenshots

The effect of running in x86 simulator is as follows:

2. Design steps

Based on the example in the previous section, you only need to add the following steps.

(1) Modify layout file

Rename demo02_fragment.xml to demo02_fragment.xml. The purpose of this is to facilitate the observation of the layout file corresponding to the example.

(2) Add Demo03MapFragment.cs

Add this file under SrcSdkDemos.

    }

(3) Modify MainActivity.cs

Add the following code in the demos field definition of the MainActivity.cs file.

<span style="color: #008000;">          //</span><span style="color: #008000;">示例3--MapFragment使用</span>
            <span style="color: #0000ff;">new</span> DemoInfo<activity><span style="color: #000000;">(Resource.String.demo_title_map_fragment,
                Resource.String.demo_desc_map_fragment,
                </span><span style="color: #0000ff;">new</span> Demo03MapFragment()),</activity>

Run and observe the results.
