finding角地图上找到最接近的药房
原标题:finding the nearest pharmacy on google maps

我正在拟定一份申请,发现安的药房、医院等最接近。

I can get my location details on the phone but how I can find places near by me? Can google maps provide a search on mapview by place name?

问题回答

这将是寻找药剂一词的一种方法。

String url = "http://maps.google.co.uk/maps?q=Pharmacy&hl=en"
Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse(url));      intent.setClassName("com.google.android.apps.maps","com.google.android.maps.MapsActivity");
startActivity(intent);

你们可以看看地图.google.com,了解如何界定你搜寻的捆绑箱的更多细节。

这样做的最佳方式是建立一个数据库中一个药房清单。 在查询数据库时,或许可以在当地或服务器上,使用收获公式,在查询数据库时,会发现最靠近贵地点的地方。

SELECT id, ( 3959 * acos( cos( radians(37) ) * cos( radians( lat ) ) * cos( radians( lng ) - radians(-122) ) + sin( radians(37) ) * sin( radians( lat ) ) ) ) AS distance FROM markers HAVING distance < 25 ORDER BY distance LIMIT 0 , 20;

以上理论并非针对甲状腺,而是了解如何找到最接近用户的地点的良好理论,我开发了类似于生态学的内容,并认为理论非常有用。

我研制了同样类型的应用,这些应用在最接近的自动取款机上。 逻辑非常简单,你需要首先在一张桌子上储存所有沥青 s子,现在通过计算目前的排泄物细节,找到最接近的距离。
