无法使用Google服务运行Android项目Google Maps V2
我正在尝试运行一个简单的android项目来显示地图 我已经遵循了谷歌地图中的所有步骤，但eclipse只是阻止了尝试启动该项目 1-我将无法使用Google服务运行Android项目Google Maps V2,android,google-maps-android-api-2,Android,Google Maps Android Api 2,我正在尝试运行一个简单的android项目来显示地图 我已经遵循了谷歌地图中的所有步骤，但eclipse只是阻止了尝试启动该项目 1-我将google-play-services_lib添加到我的工作区。 2-我在工作区复制了它。 3-我创建了一个android项目，其中包括： 清单 活动\u main.xml <?xml version="1.0" encoding="utf-8"?> <fragment xmlns:android="http://schemas.andro
google-play-services_lib<?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.MapFragment"/>
显示用于初始化映射的代码。logcat显示“错误膨胀类片段”，因此在创建映射时出现问题。您的xml文件看起来很好，代码我不知道 但看起来应该是这样的
private void initilizeMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getActivity().getFragmentManager()
.findFragmentById(R.id.map)).getMap();
// check if map is created successfully or not
if (googleMap == null) {
Toast.makeText(
getActivity().getApplicationContext(),
getActivity().getApplicationContext()
.getResources()
.getString(R.string.map_toast),
Toast.LENGTH_SHORT).show();
}
}
}
这是一段代码，我用来初始化片段内的映射，将其更改为您需要的 Manifest.xml

main.xml
在主活动中添加此
private GoogleMap mMap;
setUpMapIfNeeded();
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the
// map.
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.

类型MainActivity的方法getSupportFragmentManager（）未定义。我已经导入了import com.google.android.gms.maps.SupportMapFragment确保还导入了android.support.v4.app.FragmentActivity；MainActivity的ClassNotFoundException。有什么想法吗？
