Android实现app跳转导航app

1：实现逻辑，点击一个按钮去判断当前使用的Android手机中是否有安装导航app（百度，高德）
点击按钮判断逻辑实现

 @Override
    public void onClick(View v) {
    
    
        if (isNavigationApk(MainActivity.this, "com.baidu.BaiduMap")) {
    
    
            //百度地图
            goBaiduMap(MainActivity.this, latitude, longtitude, address);
        } else if (isNavigationApk(MainActivity.this, "com.autonavi.minimap")) {
    
    
            //高德地图
            goGaodeMap(MainActivity.this, latitude, longtitude, address);
        } else {
    
    
            Toast.makeText(MainActivity.this, "您尚未安装百度地图", Toast.LENGTH_SHORT).show();
        }
    }

判断是否安装代码块

 /**
     * 判断手机中是否有导航app
     * @param activity
     * @param packagename 包名
     */
    public static boolean isNavigationApk(Activity activity, String packagename) {
    
    
        List<PackageInfo> packages = activity.getPackageManager().getInstalledPackages(0);
        for (int i = 0; i < packages.size(); i++) {
    
    
            PackageInfo packageInfo = packages.get(i);
            if (packageInfo.packageName.equals(packagename)) {
    
    
                return true;
            } else {
    
    
                continue;
            }
        }
        return false;
    }

跳转百度地图，这里需要自己去定位获取当前位置的纬度和经度，及导航的目的地

/**
     * 跳转到百度地图
     * @param activity
     * @param latitude 纬度
     * @param longtitude 经度
     * @param address 终点
     * */
    private void goBaiduMap(Activity activity,String latitude, String longtitude, String address) {
    
    
        if (isNavigationApk(activity, "com.baidu.BaiduMap")) {
    
    
            try {
    
    
                Intent intent = Intent.getIntent("intent://map/direction?destination=latlng:"
                        + latitude + ","
                        + longtitude + "|name:" + address + //终点：该地址会在导航页面的终点输入框显示
                        "&mode=driving&" + //选择导航方式 此处为驾驶
                        "region=" + //
                        "&src=#Intent;scheme=bdapp;package=com.baidu.BaiduMap;end");
                activity.startActivity(intent);
            } catch (URISyntaxException e) {
    
    
                Log.e("goError", e.getMessage());
            }
        } else {
    
    
            Toast.makeText(activity, "您尚未安装百度地图", Toast.LENGTH_SHORT).show();

        }
    }

跳转到高德地图

/**
     * 跳转到高德地图
     * @param activity
     * @param latitude 纬度
     * @param longtitude 经度
     * @param address 终点
     * */
    private void goGaodeMap(Activity activity,String latitude, String longtitude, String address) {
    
    
        if (isNavigationApk(activity, "com.autonavi.minimap")) {
    
    
            try {
    
    
                Intent intent = Intent.getIntent("androidamap://navi?sourceApplication=&poiname=" + address + "&lat=" + latitude
                        + "&lon=" + longtitude + "&dev=0");
                activity.startActivity(intent);
            } catch (URISyntaxException e) {
    
    
                Log.e("goError", e.getMessage());
            }
        } else {
    
    
            Toast.makeText(activity, "您尚未安装高德地图", Toast.LENGTH_SHORT).show();
        }
    }
