Question

我一直在为我的Android项目添加一个地图，当我的类加载带有地图片段的XML文件时，它崩溃了，我正在学习本教程

（https://developers.google.com/maps/documentation/android/start#the_google_maps_api_key）

我正在使用Nexus 7（Jellybean 4.1），所以这应该不是问题，这是我的班级：

package com.app.thetoolstore;

import android.app.Activity;
import android.os.Bundle;

public class Tool_map extends Activity{

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_activity);
    }


}

这是我的XML：

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#001" >


<fragment xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/map"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:name="com.google.android.gms.maps.MapFragment"/>



</LinearLayout>

最后我的Stack Trace：

更新

我使用本教程https://docs.google.com/document/pub?id=19nQzvKP-CVLd7_VrpwnHfl-AE9fjbJySowONZZtNHzw解决了这个问题，特别是我遇到了 libs 和google-pay服务的问题。

Answer 1

很多问题 1）您需要使用FragmentActivity而不是Activity

2）android：name =“com.google.android.gms.maps.MapFragment”替换为android：name =“com.google.android.gms.maps.SupportMapFragment”/＆gt;

3）您需要在清单文件中添加密钥并使用Google Android Map API v2

4）参考本教程http://www.vogella.com/articles/AndroidGoogleMaps/article.html
