我从未尝试过谷歌地图。这是一个客户端项目，他们使用
compile project(':google-play-services_lib')
我必须改进他们的设计以支持最新版本的android
compile 'com.android.support:appcompat-v7:25.1.1'
它显示了一个错误，所以我试试link。
它说可以通过将Google Play服务依赖关系更新为6.1。+。来修复。
然后我用
compile 'com.google.android.gms:play-services:10.2.0'
支持最新版本的android。
然后它显示错误getMap()，因此我将其转换为getMapAsync()，但是什么是private static GoogleMap googlemap;，然后将其分配为：
googlemap=((MapFragment)getFragmentManager().findFragmentById(R.id.places_map)).getMap();
当我将其转换为
时 googlemap = ((SupportMapFragment)getActivity().getSupportFragmentManager().findFragmentById(R.id.map)).getMapAsync(this);
它告诉我错误。怎么做
public class Frnt_mapActivity extends AppCompatActivity implements OnMapReadyCallback {//implements OnMapClickListener, OnMarkerDragListener {
public static double Shop_lat;
public static double Shop_lng;
public String Shop_title;
public String Shop_address;
public String Shop_icons;

}
});

/*new Get_normal_search().execute();
edit_search.setText("");*/
}else
new Get_normal_search().execute();
edit_search.setText("");
//new GetSearch_data().execute();
}
});
}
他们正在调用googlemap并添加标记。我该如何实现呢
@Override
protected void onPostExecute(String s) {
super.onPostExecute(s);
try{
if(bd!=null){
Marker marker=googlemap.addMarker(new MarkerOptions()
.position(new LatLng(Double.parseDouble(venue.getLatitude()), Double.parseDouble(venue.getLongitude())))
.title(venue.getPost_title())
.icon(bd));
hashMap.put(marker, k);
}
}catch (Exception e){
e.printStackTrace();
}
}
switch (Integer.parseInt(venueList.get(k).getId()))
{
case 5689 :
Marker marker=googlemap.addMarker(new MarkerOptions()
.position(new LatLng(la, ln))
.title(venueList.get(k).getPost_title())
.icon(BitmapDescriptorFactory.fromResource(R.drawable.fruitandveg)));
hashMap.put(marker, k);
break;
case 5779 :
Marker marker1=googlemap.addMarker(new MarkerOptions()
.position(new LatLng(la, ln))
.title(venueList.get(k).getPost_title())
.icon(BitmapDescriptorFactory.fromResource(R.drawable.coffee)));
hashMap.put(marker1, k);
break;
.....}
答案 0 :(得分：1)
这是一个客户端项目，他们使用编译项目（＆＃39;：google-play-services_lib＆＃39;）
所以，你用它替换它（注意-maps）
compile 'com.google.android.gms:play-services-maps:10.2.0'然后它显示错误getMap（）所以我将其转换为getMapAsync（）
哪个是正确的，但是
你真的不应该有一个static地图变量。如果应用程序中存在static个变量，则设计中出现问题。
当我将其转换为
googlemap = ((SupportMapFragment)getActivity().getSupportFragmentManager().findFragmentById(R.id.map)).getMapAsync(this);时显示错误
嗯，是的，错误
1）getActivity()不是必需的。您已经在Activity班级
2）只有getSupportFragmentManager()（或extends AppCompatActivity）在课程定义
FragmentActivity
除非你getMapAsync(this)在类定义上，否则{3>} implements OnMapReadyCallback将无效。
如果你做了所有这些，那么你会有类似
的东西import com.google.android.gms.maps.OnMapReadyCallback;
public class YourActivity extends AppCompatActivity
implements OnMapReadyCallback {
private void SupportMapFragment mMapFragment;
// private GoogleMap mMap; // Commented so you don't use in onCreate
@Override
public void onMapReady(GoogleMap map) {
// this.mMap = map;
map.setMapType(GoogleMap.MAP_TYPE_NORMAL);
// TODO: call other map setup methods
}
// Inside onCreate
mMapFragment = getSupportFragmentManager().findFragmentById(R.id.map);
mMapFragment.getMapAsync(this);
// Don't do this in onCreate
// googlemap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
}
