app调用百度地图导航或者高德地图导航

一.百度导航调用方法:

    public static void goBaidu(Context context, LatLng start, LatLng endPt) {
        Intent intent = null;
        if (AppUtils.isInstallApp(BAIDU_PACKAGE_NAME)) {
            try {
            String pareUrl = "baidumap://map/direction?region=" +
                    "&origin=" + start.latitude + "," + start.longitude +
                    "&destination=" + endPt.latitude + "," + endPt.longitude + "&mode=walking";
              intent = Intent.getIntent(pareUrl);
               context.startActivity(intent);
              } catch (URISyntaxException e) {
                  e.printStackTrace();
              }      
          } else {
            ToastUtil.show("请先安装百度地图");
        }
      }

更多请查看百度官方文档走，去看看

二.高德地图导航调用方式

   public static void goGd(Context context, LatLng endPt) {
        if (AppUtils.isInstallApp(GD_PACKAGE_NAME)) {
            Intent intent = new Intent("android.intent.action.VIEW",
                    android.net.Uri.parse("androidamap://route?sourceApplication=" + AppUtils.getAppName() + "&poiname=&dlat=" + endPt.latitude
                            + "&dlon=" + endPt.longitude + "&dev=0&t=0&style=2"));
            context.startActivity(intent);
        } else {
            ToastUtil.show("请先安装高德地图");
        }
    }

高德地图更多信息请看官方文档走你

代码中需要的其他方法：

    public static final String GD_PACKAGE_NAME = "com.autonavi.minimap";
    public static final String BAIDU_PACKAGE_NAME = "com.baidu.BaiduMap";

    /**
     * 判断App是否安装
     *
     * @param packageName 包名
     * @return {@code true}: 已安装
{@code false}: 未安装
     */
    public static boolean isInstallApp(String packageName) {
        return !isSpace(packageName) && IntentUtils.getLaunchAppIntent(packageName) != null;
    }

    private static boolean isSpace(String s) {
        if (s == null) return true;
        for (int i = 0, len = s.length(); i < len; ++i) {
            if (!Character.isWhitespace(s.charAt(i))) {
                return false;
            }
        }
        return true;
    }

    /**
     * 获取打开App的意图
     *
     * @param packageName 包名
     * @return intent
     */
    public static Intent getLaunchAppIntent(String packageName) {
        return AppContext.appContext.getPackageManager().getLaunchIntentForPackage(packageName);
    }

以上就是百度和高德第三方调起导航的方法。
愿每一个程序员都别遇到内置导航的需求！！！
