Question

我正在尝试创建一个基本的Google Maps Android应用程序。在我创建项目并获取API密钥后，我遇到了此错误。

“错误：类型不兼容：片段无法转换为SupportMapFragment”

从行中的

： SupportMapFragment mapFragment =（SupportMapFragment）getSupportFragmentManager（）。findFragmentById（R.id.map）;

Java代码：（一切都是android studio生成的）

e.getEdge()

XML：

import android.support.v4.app.FragmentActivity;
import android.os.Bundle;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
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;


public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

    private GoogleMap mMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
        getSupportFragmentManager();
        // Obtain the SupportMapFragment and get notified when the map is ready to be used.
        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);

    }

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

        // Add a marker in Sydney and move the camera
        LatLng sydney = new LatLng(-34, 151);
        mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
        mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
    }
}

我能够通过更改

中gradle的依赖项来解决问题

implementation 'com.google.android.gms:play-services-maps:17.0.0'

到

implementation 'com.google.android.gms:play-services-maps:16.0.0'
