瓦片地图加载

高德地图为例

// 初始化

TileOverlayOptions TileOverlayOptions tileOverlayOptions = new TileOverlayOptions();

tileOverlayOptions.tileProvider(heatmapTileProvider); // 设置瓦片图层的提供者

// 向地图上添加 TileOverlayOptions 类对象

mAMap.addTileOverlay(tileOverlayOptions);

TileOverlayOptions tileOverlayOptions =
        new TileOverlayOptions().tileProvider(new UrlTileProvider(256, 256) {

            @Override
            public URL getTileUrl(int x, int y, int zoom) {

                Log.i("返回的值","x="+x+"y="+y+"zoom="+zoom);
                try {
                    Log.i("返回的值4444",new URL(String.format(tileUrl+"/"+zoom+"/"+x+"/"+y+".png", zoom, x, y)) +"");
                    return new URL(String.format(tileUrl+"/"+zoom+"/"+x+"/"+y+".png", zoom, x, y));
                } catch (Exception e) {

        });
