Utils的主代码为：

public class Utils {


    /**
     * 开始定位
     */
    public final static int MSG_LOCATION_START = 0;
    /**
     * 定位完成
     */
    public final static int MSG_LOCATION_FINISH = 1;
    /**
     * 停止定位
     */

    /**
     * 根据定位结果返回定位信息的字符串
     *
     * @return
     */
    public synchronized static String getLocationStr(AMapLocation location, final int index) {
        if (null == location) {
            return null;
        }
        StringBuffer sb = new StringBuffer();
        //errCode等于0代表定位成功，其他的为定位失败，具体的可以参照官网定位错误码说明
        if (location.getErrorCode() == 0) {
            sb.append("定位成功" + "\n");
            sb.append("定位类型: " + location.getLocationType() + "\n");
            sb.append("
