我从路径导入库：adt-bundle-linux-x86-20131030/sdk/extras/google/google_play_services/libproject//google-play-services_lib/我也做了参考，但仍然没有任何反应。不知道该怎么办。

Answer 1

我怀疑您没有正确引用Google Play服务库项目。确保先这样做。

<uses-sdk
        android:minSdkVersion="8"

您的最小 sdk 为 8。使用SupportMapFragment和扩展FragmentActivity并使用支持库。

或将 API 级别更改为 12 及更高。

你也失踪了

<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />

在清单的应用程序标记中

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

确保您已正确引用Google Play服务库项目，并按照上述链接中的所有步骤进行操作

Answer 2

替换它：

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

有了这个：

<?xml version="1.0" encoding="utf-8"?>
    <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.SupportMapFragment"/>

在 Maifest 中添加以下内容：

<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />

Answer 3

你的MapFragment应该这样定义。

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

Answer 4

在 AndroidManifest 中添加此内容.xml

<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
