笔记记录:
百度地图对应缩放级别
int[] zoomLevel = { 20, 19, 18, 17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6,5, 4, 3 };

对应级别单位
String[] zoomLevelStr = { “10”, “20”, “50”, “100”, “200”, “500”, “1000”,
“2000”, “5000”, “10000”, “20000”, “25000”, “50000”, “100000”,
“200000”, “500000”, “1000000”, “2000000” }; // 单位/m

/**  * 获取缩放级别  * @param distance 2点之间距离 * @return int zoomLevel  */     public int getZoomLevel(float distance) {        int mid = (int) (distance * 100);        for (int i = 0; i < zoomLevelStr.length; i++) {            if (i < zoomLevelStr.length - 1) {                int left = Integer.valueOf(zoomLevelStr[i]);                int right = Integer.valueOf(zoomLevelStr[i + 1]);                if (mid < left) {                    return zoomLevel[i];                } else if (mid > left && mid < right) {                    return zoomLevel[i + 1];                }            } else {                return 3;            }        }        return 18;    }

LatLng llCentre = new LatLng(location.getLatitude(),location.getLongitude()); MapStatus.Builder builder = new MapStatus.Builder(); builder.target(llCentre )//缩放中心点 .zoom(zoomLv)//缩放级别 mBaiduMap.animateMapStatus(MapStatusUpdateFactory .newMapStatus(builder.build()));
