Android应用拉取第三方地图（百度，高德，以及网页地图）

        最近项目中需要添加一个对于目的地的导航功能,查阅了不少资料发现都是比较老的内容于是准备自己写个地图功能，下面直接开始，用到的几个链接：

百度调起app传送门:http://lbsyun.baidu.com/index.php?title=uri

百度网页调起地图传送门：http://lbsyun.baidu.com/index.php?title=uri/api/web

高德调起pp传送门:http://lbs.amap.com/api/amap-mobile/summary/

        本文只展示了打点地址的功能，其他功能读者可以自行参考api文档自己研究，首先为了能够调起第三方地图app必须得先判断是否安装了地图app代码如下：

/**
 * 地图应用是否安装
 * @return
 */
public static boolean isGdMapInstalled(){
    return isInstallPackage("com.autonavi.minimap");
}

public static boolean isBaiduMapInstalled(){
    return isInstallPackage("com.baidu.BaiduMap");
}

private static boolean isInstallPackage(String packageName) {
    return new File("/data/data/" + packageName).exists();
}

这里如果存在就进行跳转，百度跳转如下：

/**
 * 打开百度地图
 */
/**
 *
 * @param slat 纬度
 * @param slon 经度
 * @param content 内容
 */
private void openBaiduMap(double slat, double slon, String content) {
    if (OpenLocalMapUtil.isBaiduMapInstalled()) {
        try {
            String uri = OpenLocalMapUtil.getBaiduMapUri(String.valueOf(slat), String.valueOf(slon), content);
            Intent intent = new Intent();
            intent.setData(Uri.parse(uri));
            startActivity(intent); //启动调用
            isOpened = true;
        } catch (Exception e) {
            isOpened = false;
            e.printStackTrace();
        }
    } else {
        isOpened = false;
    }
}

高德跳转如下：

/**
 * 打开高德地图
 */
/**
 *
 * @param dlat 纬度
 * @param dlon 纬度
 * @param content 终点
 */
private void openGaoDeMap(double dlat, double dlon, String content) {
    if (OpenLocalMapUtil.isGdMapInstalled()) {
        try {
            //百度地图定位坐标转换成高德地图可识别坐标
            double[] loca = new double[2];
            loca = OpenLocalMapUtil.gcj02_To_Bd09(dlat, dlon);
            String uri = OpenLocalMapUtil.getGdMapUri(APP_NAME,
                    String.valueOf(loca[0]), String.valueOf(loca[1]), content);
            Intent intent = new Intent();
            intent.setAction(Intent.ACTION_VIEW);
            intent.addCategory(Intent.CATEGORY_DEFAULT);
            intent.setPackage("com.autonavi.minimap");
            intent.setData(Uri.parse(uri));
            startActivity(intent); //启动调用
            isOpened = true;

        } catch (Exception e) {
            isOpened = false;
            e.printStackTrace();
        }
    } else {
        isOpened = false;
    }
}

浏览器打开百度地图：

/**
 * 打开浏览器进行百度地图导航
 */
/**
 *
 * @param dlat 纬度
 * @param dlon 经度
 * @param dname 终点
 * @param content 地点内容
 */
private void openWebMap(double dlat, double dlon, String dname, String content) {
    Uri mapUri = Uri.parse(OpenLocalMapUtil.getWebBaiduMapUri(
            String.valueOf(dlat), String.valueOf(dlon),
            dname, content, APP_NAME));
    Intent loction = new Intent(Intent.ACTION_VIEW, mapUri);
    startActivity(loction);
}

上面我OpenLocalMapUtil是我创建的一个工具类：

因为百度和高德坐标不能通用所以在使用前必须进行转换。
