Question

我正在尝试实现google mapsview以在片段中显示我的当前位置。我必须离开这个（公共类FragmentFind扩展Fragment实现OnMapReadyCallback {），因为它是导航底视图中的一个选项卡，这是它唯一的工作方式。如果您可以提供帮助，请告诉我。我尝试更改上面的行并使用Fragment Activity，但它不起作用。

package com.project.findme;
import android.location.Location;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.google.android.gms.location.FusedLocationProviderClient;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapView;
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 FragmentFind extends Fragment implements OnMapReadyCallback {


private MapView mapView;
private GoogleMap googleMap;


public FragmentFind() {
    // Required empty public constructor
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment

    return inflater.inflate(R.layout.activity_maps, container, false);
}

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    mapView = (MapView) view.findViewById(R.id.map);
    mapView.onCreate(savedInstanceState);
    mapView.onResume();
    mapView.getMapAsync(this);
}



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

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

}

这是activity_maps.xml

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.gms.maps.MapView
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="613dp"
    android:layout_marginBottom="70dp" />

在导航底部的“ Google地图片段”标签中实现当前位置
