克隆Uber时requestLocationUpdates方法无法解析问题求助

问题描述

我正在复刻Uber应用，需要获取司机的实时位置，但调用LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient,locationRequest,this);时出现错误：

Cannot resolve method 'requestLocationUpdates(com.google.android.gms.common.api.GoogleApiClient, android.location.LocationRequest, com.example.codingcafe.cab.DriversMapActivity)'

我已经尝试在类中实现LocationListener、修改build.gradle中的gms-location依赖，但都没解决问题。以下是我的代码：

package com.example.codingcafe.cab;


import android.Manifest;
import android.content.pm.PackageManager;
import android.location.Location;
import android.location.LocationRequest;
import android.os.Build;
import android.os.Bundle;

import androidx.annotation.NonNull;
import androidx.annotation.Nullable;
import androidx.core.app.ActivityCompat;
import androidx.fragment.app.FragmentActivity;

import com.example.codingcafe.cab.databinding.ActivityDriversMapBinding;
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.location.LocationServices;
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;
import android.location.LocationListener;

public class DriversMapActivity extends FragmentActivity implements OnMapReadyCallback,
        GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener,
        com.google.android.gms.location.LocationListener{

    private GoogleMap mMap;
    private ActivityDriversMapBinding binding;
    GoogleApiClient googleApiClient;
    Location LastLocation;
    LocationRequest locationRequest;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        binding = ActivityDriversMapBinding.inflate(getLayoutInflater());
        setContentView(binding.getRoot());

        // 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);
    }

    /**
     * Manipulates the map once available.
     * This callback is triggered when the map is ready to be used.
     * This is where we can add markers or lines, add listeners or move the camera. In this case,
     * we just add a marker near Sydney, Australia.
     * If Google Play services is not installed on the device, the user will be prompted to install
     * it inside the SupportMapFragment. This method will only be triggered once the user has
     * installed Google Play services and returned to the app.
     */
    @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.newLatLngZoom(sydney,17));
    }

    @Override
    public void onConnected(@Nullable Bundle bundle) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
            locationRequest = new LocationRequest.Builder( 1000)
                    .setMinUpdateIntervalMillis(500)
                    .setQuality(LocationRequest.QUALITY_HIGH_ACCURACY)
                    .setMaxUpdateDelayMillis(1000)
                    .build();

        }

        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
                != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this,
                Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)
        {
            return;
        }
        LocationServices.FusedLocationApi.requestLocationUpdates(googleApiClient,locationRequest,this);

        //it will handle the refreshment of the location
        //if we dont call it we will get location only once

    }

    @Override
    public void onConnectionSuspended(int i) {

    }

    @Override
    public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

    }

    @Override
    public void onLocationChanged(Location location) {

    }
}
错误原因&修复方案

核心问题

  1. 废弃API混用：LocationServices.FusedLocationApi是已淘汰的旧版定位API，Google现在推荐使用FusedLocationProviderClient替代。
  2. LocationRequest类型不匹配：你导入的是系统自带的android.location.LocationRequest，但Google定位API需要的是com.google.android.gms.location.LocationRequest。
  3. GoogleApiClient未初始化：代码仅声明了GoogleApiClient变量，但没有完成构建和连接流程，导致调用时为空对象。

修复步骤

  1. 替换废弃的FusedLocationApi为FusedLocationProviderClient，使用现代定位API。
  2. 修正LocationRequest的导入，使用Google定位库的版本。
  3. 在onCreate中完成GoogleApiClient的构建与连接。
  4. 补充权限申请逻辑，适配Android动态权限机制。

额外配置说明

  • 依赖版本：确保Module级build.gradle中使用最新的Google服务依赖：
    implementation 'com.google.android.gms:play-services-location:21.0.1'
implementation 'com.google.android.gms:play-services-maps:18.2.0'
  • Manifest权限：在AndroidManifest.xml中添加必要权限：
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<!-- 若需要后台定位，添加以下权限（Android 12+） -->
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
