【问题描述】：

我正在使用 google Places API（已激活支付）我得到了密钥，当将其添加到我的应用程序时，搜索效果很好，但是，地图本身不工作它显示为空白，下面我可以看到 google 徽标

我的 XML

    <fragment
        android:id="@+id/map_fragment"
        android:name="com.google.android.gms.maps.MapFragment"
        android:layout_
        android:layout_ />

还有我用于声明地点 API 和地图的 java 代码

    private void initMapsAndPlaces() 
        mFusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this);
        Places.initialize(this, mApiKey);
        placesClient = Places.createClient(this);
        final AutocompleteSessionToken token = AutocompleteSessionToken.newInstance();

        MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map_fragment);
        mapFragment.getMapAsync(this);
        mapView = mapFragment.getView();

        materialSearchBar.setOnSearchActionListener(new MaterialSearchBar.OnSearchActionListener() 
            @Override
            public void onSearchStateChanged(boolean enabled) 
            

            @Override
            public void onSearchConfirmed(CharSequence text) 
                startSearch(text.toString(), true, null, true);
            

            @Override
            public void onButtonClicked(int buttonCode) 
                if (buttonCode == MaterialSearchBar.BUTTON_BACK) 
                    materialSearchBar.disableSearch();
                    materialSearchBar.clearSuggestions();
                
            
        );

        materialSearchBar.addTextChangeListener(new TextWatcher() 
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) 
            

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) 
                FindAutocompletePredictionsRequest predictionsRequest = FindAutocompletePredictionsRequest.builder()
                        .setCountry(mCountry)
                        .setSessionToken(token)
                        .setQuery(s.toString())
                        .build();
                placesClient.findAutocompletePredictions(predictionsRequest).addOnCompleteListener(new OnCompleteListener<FindAutocompletePredictionsResponse>() 
                    @Override
                    public void onComplete(@NonNull Task<FindAutocompletePredictionsResponse> task) 
                        if (task.isSuccessful()) 
                            FindAutocompletePredictionsResponse predictionsResponse = task.getResult();
                            if (predictionsResponse != null) 
                                predictionList = predictionsResponse.getAutocompletePredictions();

添加权限

    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

谁能帮帮我，好吗？

如果还有人在受苦

找了半天，错过了添加

        <meta-data
            android:name="com.google.android.geo.API_KEY"
            android:value="@string/places_api_key" />
