我正在尝试在我的Android应用中实现Google地图。以下是我的代码：
private GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.connect);
initilizeMap();
googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
googleMap.setMyLocationEnabled(true);
googleMap.getUiSettings().setZoomControlsEnabled(false);
googleMap.getUiSettings().setMyLocationButtonEnabled(true);
googleMap.getUiSettings().setCompassEnabled(true);
googleMap.getUiSettings().setRotateGesturesEnabled(true);
googleMap.getUiSettings().setZoomGesturesEnabled(true);
}
private void initilizeMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
// check if map is created successfully or not
if (googleMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
和我的xml文件：
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</LinearLayout>

我甚至在我的MANIFEST文件中添加了API密钥。我已导入Google Play库文件，几乎所有内容都已完成。但它没有运行。该项目直接崩溃。我也安装了Google Play服务。可以做些什么？有人可以帮忙吗？这是紧急情况。
答案 0 :(得分：0)
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
将此行添加到您的清单中。
答案 1 :(得分：0)
我在片段中实现了地图的类似问题。所以我制作了一个FrameLayout布局文件，并使用了com.google.android.gms.maps.MapView而不是Mapfragment。 你可以看看here
它也适用于支持库
答案 2 :(得分：0)
您的logcat说无法找到MapFragment
在您的XML更改android:name更改为class
所以你的XML应该是这样的
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
