用 getMapAsync 替换 getMap [英] Replace getMap with getMapAsync

问题描述

我想用 getMapAsync 替换已弃用的 getMap 方法，但我没有使用 MapFragment 而是 GoogleMap> 像这样:

I want to replace the deprecated getMap Method with getMapAsync, but I didn't use MapFragment but GoogleMap like this:

private GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map);

    try {
        if(googleMap == null) {
            googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
        }
        googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
        googleMap.setMyLocationEnabled(true);
        googleMap.setTrafficEnabled(true);
        googleMap.setIndoorEnabled(true);
        googleMap.setBuildingsEnabled(true);
        googleMap.getUiSettings().setZoomControlsEnabled(true);

如果我像这样将 googleMap 替换为 MapFragment，我将无法再使用 setMapType 等等.那么在我的情况下如何更改为 getMapAsync ?

If I replace the googleMap with MapFragment like this I'm not able anymore to setMapType and so on. So how can I change to getMapAsync in my case?

MapFragment mapFragment = (MapFragment) getFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

推荐答案

在官方文档中，get map async 需要回调；它是谷歌地图内容的主要入口点"！

as in the official doc, get map async requires a callback; it's there your "main entry point" for google maps stuff!

public class MapPane extends Activity implements OnMapReadyCallback {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_activity);

        MapFragment mapFragment = (MapFragment) getFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
    }

    @Override
    public void onMapReady(GoogleMap map) {
        // DO WHATEVER YOU WANT WITH GOOGLEMAP
        map.setMapType(GoogleMap.MAP_TYPE_HYBRID);
        map.setMyLocationEnabled(true);
        map.setTrafficEnabled(true);
        map.setIndoorEnabled(true);
        map.setBuildingsEnabled(true);
        map.getUiSettings().setZoomControlsEnabled(true);
    }
}
