获取地图地址或位置的地址Android中

本文介绍了获取地图地址或位置的地址Android中的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我写一个应用程序，需要获取当前地图上的位置。我的地图文件工作正常，通过它的自我，但我需要从另一个活动 addressString 要低于BUTTOM） $ C>。我试过的getAddress / setAddress （设置器/吸气）。他们不工作。他们总是返回无地址（默认值）。

下面是我的code ...

我怎样才能使这是一个独立的Java类???或者从另一个活动获得的地址？

多谢了。

这code工作本身。

I am writing an app that requires to get the current map location. My Map file works fine by it self, but I need to get the address (see addressString below at the buttom) from another Activity. I tried getAddress/setAddress (setters/getters). They do not work. They always return 'no address' (the default).

Here is my code...

How can I make this a standalone Java class??? Or get the address from another activity?

Thanks a lot.

This code works by itself.

解决方案

I have used the following code in my app and its working absolutely fine for me. Try this. Hope this will help you.

    //
    //  Write the location name.
    //

    try {

        Geocoder geo = new Geocoder(youractivityclassname.this.getApplicationContext(), Locale.getDefault());
        List<Address> addresses = geo.getFromLocation(latitude, longitude, 1);
        if (addresses.isEmpty()) {
            yourtextfieldname.setText("Waiting for Location");
        }
        else {
            if (addresses.size() > 0) {
                yourtextfieldname.setText(addresses.get(0).getFeatureName() + ", " + addresses.get(0).getLocality() +", " + addresses.get(0).getAdminArea() + ", " + addresses.get(0).getCountryName());
                //Toast.makeText(getApplicationContext(), "Address:- " + addresses.get(0).getFeatureName() + addresses.get(0).getAdminArea() + addresses.get(0).getLocality(), Toast.LENGTH_LONG).show();
            }
        }
    }
    catch (Exception e) {
        e.printStackTrace(); // getFromLocation() may sometimes fail
    }
