在您的android应用程序中设置Google地图的样式

您是否对旧式的Google地图感到厌倦，并想将其浸透在眼前的色彩和良好的感觉？

您可以使用JSON文件为主题类型和样式添加漂亮的主题和颜色。

您需要创建一个JSON文件，以其颜色指定google地图的所有属性/元素和特征。

一个典型的样式JSON文件如下所示：

{
   "elementType": "geometry",
    "stylers": [
      {
       "color": "#1d2c4d"
      }
    ]
  },
  {
    "elementType": "labels.text.fill",
    "stylers": [
      {
        "color": "#8ec3b9"
      }
    ]
  },
  {
    "elementType": "labels.text.stroke",
    "stylers": [
      {
        "color": "#1a3646"

您需要将JSON文件放入“ res”文件夹下的“ raw”文件夹中。

现在，为了将JSON文件呈现到Google Map中，您需要将JSON应用于MAP，如下例所示：

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.OnMapReadyCallback;
import com.google.android.gms.maps.SupportMapFragment;

public class MapActivity extends FragmentActivity implements OnMapReadyCallback {



 private GoogleMap mMap;
  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_map);

    }


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

        try {
            boolean success = googleMap.setMapStyle(
                    MapStyleOptions.loadRawResourceStyle(
                            MapActivity.this, R.raw.map_style));
            if (!success) {
                Log.e("Style parsing error: ", "Style parsing failed.");
            }
        } catch (Resources.NotFoundException e) {
            Log.e("----", "Can't find style. Error: ", e);
        }

    }

}


       
 

在您的主要活动中， onMapReady（） 方法，您需要通过调用将JSON样式加载到地图 loadRawResourceStyle（） 通过传递JSON文件的方法 “ map_style.json”.

在将JSON文件应用于地图后运行应用程序时，Google地图将如下所示：

您也可以使用 造型向导 创建完全自定义的地图主题或下载Google地图的现有模板。
