我试图在 stackoverflow 中找到解决方案，但似乎没有任何效果。谁能告诉我我在哪里做错了。需要做什么才能使我的项目工作。下面是我的清单文件

我的 MainActivity.java

package com.arifhaq.googlemapproject;

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

public class MainActivity extends Activity{

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

}

【问题讨论】：

标签： android google-maps android-fragments google-maps-api-2

【解决方案1】：

你的android:minSdkVersion="8" 所以你应该和SupportMapFragment一起去将您的 MainActivity 扩展到 FragmentActivity

还有变化

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

到

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

【讨论】：

我做了你上面写的，但它现在给了我 java.lang.ClassNotFound 异常
@user3393926 您是否在项目中引用了google_play_services_lib？
是的，我一开始就这样做了
是的，我早先这样做了，甚至现在将您的解决方案复制到我的布局文件并再次运行整个项目并获得相同的 java.lang.ClassNotFound 异常

【解决方案2】：

在地图活动的父布局中添加这一行 xmlns:tools="http://schemas.android.com/tools"

喜欢

<RelativeLayout 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"
tools:context=".FirstActivity" >

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

【讨论】：

这样做但现在得到 java.lang.ClassNotFound 异常
请在 AndroidMenifest 中编写 Class Entry。在您的项目中添加 google PlayService 库
试试这个 android:name="com.arifhaq.googlemapproject.MainActivity"
