Android应用调用第三方地图应用导航

项目中需要用到调用第三方地图应用导航时可参考，类似于这样：

首先需要获取到手机上已安装的地图应用：

 //获取地图应用
    private AllTwoDTO.txt_mydata getMapApk() {

        AllTwoDTO.txt_mydata mydata = new AllTwoDTO.txt_mydata();
        List mydataList = new ArrayList<>();
        List apkList = Utils.getApkList(this);
        if (apkList.contains("com.baidu.BaiduMap")){
            AllTwoDTO.txt_list txtList1 = new AllTwoDTO.txt_list();
            txtList1.setTxt_one(TYPE_B);
            txtList1.setTxt_two("百度地图");
            mydataList.add(txtList1);
        }
        if (apkList.contains("com.autonavi.minimap")){
            AllTwoDTO.txt_list txtList2 = new AllTwoDTO.txt_list();
            txtList2.setTxt_one(TYPE_A);
            txtList2.setTxt_two("高德地图");
            mydataList.add(txtList2);
        }
        if (apkList.contains("com.tencent.map")){
            AllTwoDTO.txt_list txtList3 = new AllTwoDTO.txt_list();
            txtList3.setTxt_one(TYPE_T);
            txtList3.setTxt_two("腾讯地图");
            mydataList.add(txtList3);
        }
        mydata.setTxt_list(mydataList);
        return mydata;
    }

 */
public static List getApkList(Context context) {
    //获取packagemanager
    final PackageManager packageManager = context.getPackageManager();
    //获取所有已安装程序的包信息
    List packageInfos = packageManager.getInstalledPackages(0);
    //用于存储所有已安装程序的包名
    List packageNames = new ArrayList();
    //从pinfo中将包名字逐一取出，压入pName list中
    if (packageInfos != null) {
        for (int i = 0; i < packageInfos.size(); i++) {
            String packName = packageInfos.get(i).packageName;
            packageNames.add(packName);
        }
    }
    return packageNames;
}

获取到地图应用列表做展示给用户选择，接下来才是重点，调用地图应用导航：

                     Intent intent;
                    switch (data.getStringExtra(ChoiceItemActivity.ID)) {
                        case TYPE_A://高德地图
                            try {
                                intent = Intent.getIntent("androidamap://route?sourceApplication=" + getResources().getString(R.string.app_name) + "&sname=我的位置&dlat="
                                        + ShopLatitude + "&dlon=" + ShopLongitude + "&dname=" + getIntent().getStringExtra(SHOP_TITLE) + "&dev=1&m=2&t=3");
                                startActivity(intent);
                            } catch (URISyntaxException e) {
                                showToast("您尚未安装高德地图或地图版本过低");
                                Uri uri = Uri.parse("market://details?id=com.autonavi.minimap");
                                Intent AIntent = new Intent(Intent.ACTION_VIEW, uri);
                                startActivity(AIntent);
                                e.printStackTrace();
                            }
                            break;
                        case TYPE_T://腾讯地图
                            try {
                                intent = new Intent();
                                intent.setAction(Intent.ACTION_VIEW);
                                intent.addCategory(Intent.CATEGORY_DEFAULT);
                                //将功能Scheme以URI的方式传入data
                                Uri uri = Uri.parse("qqmap://map/routeplan?type=drive&to=" + getIntent().getStringExtra(SHOP_TITLE)
                                        + "&tocoord=" + ShopLatitude + "," + ShopLongitude);
                                intent.setData(uri);
                                startActivity(intent);
                            } catch (Exception e) {
                                showToast("您尚未安装腾讯地图或地图版本过低");
                                Uri uri = Uri.parse("market://details?id=com.tencent.map");
                                Intent TIntent = new Intent(Intent.ACTION_VIEW, uri);
                                startActivity(TIntent);
                                e.printStackTrace();

                        case TYPE_B://百度地图

                                startActivity(intent);
                            } catch (Exception e) {
                                showToast("您尚未安装百度地图或地图版本过低");

                    }

ShopLatitude, ShopLongitude   //经纬度信息

注意：在调用百度地图时传递的坐标信息是做转换了，因为高德和腾讯地图用的是国家标准的火星坐标，而百度用的是百度自己加密的百度坐标，而服务器上返回的是高德的火星坐标，如果不做转化，百度地图定位惠友偏差。转化方法如下：
