Android工作室Google Map API带有片段 [英] Android studio Google Map API with fragments

问题描述

我想用片段显示简单的Google地图。
我尝试在mainActivity中调用片段：

  MapFragment.newInstance（）; 
  

这里是片段类：

  public class MapFragment extends Fragment {
 
 MapView MapView; 
 
 public static MapFragment newInstance（）{
 return new MapFragment（）; 
} 
 
 @Override 
 public View onCreateView（LayoutInflater inflater，@Nullable ViewGroup容器，@Nullable Bundle savedInstanceState）{
返回inflater.inflate（R.layout。 fragment_map，container，false）; 
} 
 @Override 
 public void onViewCreated（View view，@Nullable Bundle savedInstanceState）{
 super.onViewCreated（view，savedInstanceState）; 
 mapView =（MapView）view.findViewById（R.id.mapview）; 
 
 
 $ / code $ / pre 
 
 
和布局片段：
 
 
 <？xml version =1.0encoding =utf-8？> 
< com.google.android.gms.maps.MapFragment 
 xmlns：android =http://schemas.android.com/apk/res/android
 android：id = @ + id / mapview
 android：layout_width =match_parent
 android：layout_height =match_parent
 /> 
  
但是当在我的设备中测试它时，应该重新启动。
 
 
 
 whtas my wrong？
 
 
 
有些错误：

解决方案
 com.google.android.gms.maps.MapFragment不是MapView 
 
 
 
更改您的分段布局Xml 
 <？xml version =1.0encoding =utf-8？> 
< com.google.android.gms.maps.MapView 
 android：id =@ + id / mapview
 android：layout_width =match_parent
 android：layout_height =match_parent/> 
  
并在您的片段中找到GoogleMap实例
  MapView mapView; 
 GoogleMap地图; 
 
 @Override 
 public view onCreateView（LayoutInflater inflater，ViewGroup container，Bundle savedInstanceState）{
 View v = inflater.inflate（R.layout.some_layout，container，false）; 
 
 //从XML布局中获取MapView并创建它
 mapView =（MapView）v.findViewById（R.id.mapview）; 
 mapView.onCreate（savedInstanceState）; 
 
 //从MapView获取到GoogleMap并执行初始化操作
 map = mapView.getMap（）; 
}

I want to show a simple google map with fragment.
I try call a fragment in mainActivity:
MapFragment.newInstance();
And here is fragment class:
public class MapFragment extends Fragment {

    private MapView mapView;

    public static MapFragment newInstance() {
        return new MapFragment();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup   container, @Nullable Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_map, container, false);
    }
    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        mapView = (MapView) view.findViewById(R.id.mapview);
    }
}
and layout fragment:
<?xml version="1.0" encoding="utf-8"?>
<com.google.android.gms.maps.MapFragment
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/mapview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    />
But when test it in my device, the app be restart.

whtas my wrong?

SOME errors:

解决方案
com.google.android.gms.maps.MapFragment is not MapView

Change your fragment layout Xml
<?xml version="1.0" encoding="utf-8"?>
<com.google.android.gms.maps.MapView 
    android:id="@+id/mapview"
    android:layout_width="match_parent" 
    android:layout_height="match_parent" />
and find GoogleMap instance on your fragment
MapView mapView;
GoogleMap map;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.some_layout, container, false);

    // Gets the MapView from the XML layout and creates it
    mapView = (MapView) v.findViewById(R.id.mapview);
    mapView.onCreate(savedInstanceState);

    // Gets to GoogleMap from the MapView and does initialization stuff
    map = mapView.getMap();
}
