研究了一星期多的Osmdroid，深感這個開源的android地圖包強大，因為使用其他瓦片涉及智慧財產權，請大家謹慎使用，本文只做研究測試。

新建GoogleTileSource類繼承org.osmdroid.tileprovider.tilesource.TileSourceFactory類，具體對應的資源都有註釋

                    + "&L=" + MapTileIndex.getZoom(pMapTileIndex);
        }
    };

}

然後在主程式MainActivity中的mapview中使用如下程式碼：

        map = (MapView) findViewById(R.id.map);
        map.setTileSource(GoogleTileSource.MAPNIK)

因為是繼承的，所以原來包中自帶的OpenStreetMap、OpenSea的瓦片資源都可以繼續引用。

問題：

• 為了保密高德、谷歌.cn、天地圖使用的是GCJ02（火星座標系），手機gps資料是WGS-84座標系，需要進行轉換。
• 為什麼沒有百度，因為百度的瓦片分割和高德谷歌都不一樣，還有百度使用的自己的BD09座標系 即百度座標系，估計GCJ02座標系經加密後的座標系。
