谷歌地图中的缩放动画

Question

我正在学习在Android上使用Google Maps API，我刚刚学会了如何做到这一点。

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    mMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
    // Add a marker in Uman and move the camera
    LatLng uman = new LatLng(48.754683, 30.216339 );
    mMap.addMarker(new MarkerOptions().position(uman).title("Home Town"));
    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(uman, 10));
}

但是，我希望地图不直接加载到标记中，而是完全缩小后再缩放到标记处播放动画...

真心希望你能理解...

Answer 1

请使用mMap.animateCamera(...)而不是mMap.moveCamera(..)。

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    mMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
    // Add a marker in Uman and move the camera
    LatLng uman = new LatLng(48.754683, 30.216339 );
    mMap.addMarker(new MarkerOptions().position(uman).title("Home Town"));
    mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(uman, 10.0F));
}

尝试这个...

@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    mMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
    // Add a marker in Uman and move the camera
    LatLng uman = new LatLng(48.754683, 30.216339 );
    mMap.addMarker(new MarkerOptions().position(uman).title("Home Town"));
    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(uman, 10));
    Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        public void run() {                       
            mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(uman, 16));
        }
    }, 1000);
}

在动画方面，将moveCamera替换为animateCamera。

Java

map.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng, 15));

kotlin:

 val cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 15f)
 map.animateCamera(cameraUpdate)
