它说这个文件的第 12 行有错误：

package com.fotolife.app;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class Map extends Fragment {

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        return inflater.inflate(R.layout.map, container, false);
    }

}

第 12 行是：return inflater.inflate .....

这是片段应该膨胀的xml文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <com.google.android.maps.MapView
        android:layout_width="match_parent" 
        android:layout_height="match_parent"
        android:enabled="true"
        android:clickable="true"
        android:apiKey="@string/maps_api_key"
        />

</LinearLayout>

这是你的错误：

01-06 15:00:42.865: E/AndroidRuntime(24230): Caused by: java.lang.IllegalArgumentException: MapViews can only be created inside instances of MapActivity.

您不能MapView与片段一起使用，因为要使用片段，您的 Activity 需要是Activity(v11+) 或的子类FragmentActivity，但要使用MapView您的 Activity 必须是MapActivity.

如果您想同时使用地图和片段，则需要使用包含( v11MapFragment +) 或SupportMapFragment.

我以前从未使用过 Google Maps Android API，但查看您的堆栈跟踪：

01-06 15:00:42.865: E/AndroidRuntime(24230): Caused by: java.lang.IllegalArgumentException: MapViews can only be created inside instances of MapActivity.

您的活动需要扩展MapActivity。如果您想使用片段，也许您应该使用新的 V2 API。https://developers.google.com/maps/documentation/android/

由于您的布局仅包含 a MapView，您是否考虑过使用 aSupportMapFragment代替：

<fragment
    class="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

或者

SupportMapFragment f = new SupportMapFragment();
getSupportFragmentManager().beingTransaction()
    .add(android.R.id.content, f)
    .commit();

请参阅文档：https ://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/SupportMapFragment
