地理编码 IOException 尝试搜索最近的医院

发布于 2024-10-29 00:09:24 字数 482 浏览 0 评论 0原文

我正在尝试将医院搜索合并到我的应用程序中。它应该根据您的位置提供最近的 5 家医院。

我收到一个 IOException List geocodeResults= coder.getFromLocationName(strLocation, 5);在 Eclipse 中使用 coder.getFromLocationName(strLocation, 5);下划线是问题所在。

我还设置了位置粗略和精细以及互联网的权限,但我仍然收到此错误。

我还想获取这 5 个结果并列出医院名称、地址和距离。

我对 Android 编码还是新手。通过搜索这个网站,我发现了很多很棒且有用的帮助,所以这就是我要问的地方。

或者我希望我的应用程序将字符串“hospital”发送到谷歌地图,并让谷歌地图应用程序显示结果。我不在乎哪个。

提前感谢所有帮助

说实话,我并不完全理解上面列出的代码,我理解一些但不是全部。我确实知道这是帮助我实现目标的必要条件。

I am trying to incorporate and hospital search in my app. It is supposed to give the closest 5 hospitals based upon your location.

I am getting an IOException with List geocodeResults= coder.getFromLocationName(strLocation, 5); in Eclipse with coder.getFromLocationName(strLocation, 5); underlined being the issue.

I have also set the permissions for location coarse and fine as well as internet and still I am getting this error.

I would also like to take these 5 results and list them with the hospital name, address and miles away.

I am still new at coding for the android. I have come across a lot of great and useful help by searching this site, so here is where I am asking.

Either this or I want my app to send the string "hospital" to google maps and let google maps app display the results. I don't care which.

Thanx in advance for all the help

To be honest I do not completely understand the code I listed above, I understand some but not all. I do know it is a necessity to help me accomplish my goal.

如果您在模拟器中使用地理编码器,您将遇到一些 IO 异常。实际上,Geocoder 并不是最可靠的服务,并且经常发出“服务不可用”IO 异常。我们中的一些人一直在地理编码器调用中循环,直到它返回干净为止,而其他人则尝试了其他措施。

我认为 2.3 及更高版本中的模拟器在这方面有一个错误项目,而在 2.2 以下版本中,它的工作相当零散。

这段代码将把实际的异常输出到 toast 消息中,并记录该异常。

        String strAddress = "your address here/or location";

        try{
         List<Address> loc = geocoder.getFromLocationName(strAddress, 5);
        }
        catch(IOException e) {
         Log.e("IOException", e.getMessage());

         //Toaster on high-----------------//
     Context context = getApplicationContext();
     CharSequence text = "IOException:  " + e.getMessage();
     int dur = Toast.LENGTH_LONG;
            Toast.makeText(context, text, dur).show();

If your'e using Geocoder in the Emulator you will have some IO Exceptions. Actually Geocoder is not the most reliable service and frequently issues a "Service Unavailable" IO Exception. There have been some of us that have looped at the Geocoder call until it comes back clean and others who have tried other measures.

I think the emulator in 2.3 and above has a bug item on this and in 2.2 below it works rather sporadically.

This bit of code will output the actual exception to a toast message and will logcat the exception as well.

        String strAddress = "your address here/or location";

        try{
         List<Address> loc = geocoder.getFromLocationName(strAddress, 5);
        }
        catch(IOException e) {
         Log.e("IOException", e.getMessage());

         //Toaster on high-----------------//
     Context context = getApplicationContext();
     CharSequence text = "IOException:  " + e.getMessage();
     int dur = Toast.LENGTH_LONG;
            Toast.makeText(context, text, dur).show();
