OnMapReadyCallback无法解析为类型 [英] OnMapReadyCallback cannot be resolved to a type

问题描述

我是Android应用内的Google地图的新手，我试图测试包含在文档中的示例：

您需要创建并API项目并获取API密钥以便与地图一起工作。

更新：

可能您的版本较旧的支持库，所以删除当前并导入最后一个，你可以在你的项目中使用.jar（位于： sdk\extras\android\support\v7 ），或者您可以导入位于以下位置的库项目：
sdk\extras\android\support\v7\appcompat 。

I'm new to Google Maps inside an Android app and I'm trying to test the example that is included in the documentation: https://developers.google.com/maps/documentation/android/

I did some research and apparently this was included in the latest Google Play Services package. I really think I have the last one, but I still cannot resolve OnMapReadyCallback. This is how it looks:

Does anybody know what I could be missing?

Thanks

解决方案

Probably you need to change to Google APIs, go to properties -> Android.

So you will solve the problem implementing the class OnMapReadyCallback :

import com.google.android.gms.maps.OnMapReadyCallback;

public class MapPane extends Activity implements OnMapReadyCallback {

You need to read all the info related to Google Maps Android API V2:

https://developers.google.com/maps/documentation/android/start#getting_the_google_maps_android_api_v2

You need to create and API project and get the API key to work with Maps.

UPDATE:

probably you have an older version of the support library, so delete the current and import the last one, you can use the .jar in your project (located in: sdk\extras\android\support\v7) or you can import the library project located in: sdk\extras\android\support\v7\appcompat.
