所以我试图将Google地图合并到一个片段中,我已经按照Maps上的Google Dev文档中提到的步骤进行了操作,但是我在填充类片段时出错了。我经历了很多堆栈并完成了其中提到的所有内容,但错误仍然存在。这是我的Map Fragment,
Fragment_two.java
package com.example.TheWeddingApp;
import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.MapView;
import com.google.android.gms.maps.MapsInitializer;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FragmentTwo extends Fragment implements OnMapReadyCallback {
MapView mapView;
GoogleMap map;
public static Fragment newInstance(Context context) {
FragmentTwo f = new FragmentTwo();
return f;
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
ViewGroup root = (ViewGroup) inflater.inflate(R.layout.fragment_two, null);
getActivity().setContentView(R.layout.fragment_two);
MapFragment mapFragment = (MapFragment) getActivity().getFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
return root;
}
@Override
public void onMapReady(GoogleMap map) {
map.addMarker(new MarkerOptions()
.position(new LatLng(0, 0))
.title("Marker"));
}
}
我的地图xml,
fragment_two.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<fragment android:name="com.google.android.gms.maps.SupportMapFragment"

更新#1
实现了对此帖子的回复,但在调用地图时仍然出现空指针错误。不知怎的,我无法掌握地图。这是我得到错误的地方
mapFragment.getMapAsync(this);
这是更新后的logcat:
