如何从坐标获取街道名称?
How to get street name from coordinates?
我将经度和纬度分为两个单独的 EditText 我希望当我按下按钮时街道名称出现在另一个 EditText 中。
我试过 Public Address getAddressForLocation
方法,但我还没有成功..
代码
public Address getAddressForLocation(Context context, Location location) throws IOException {
if (location == null) {
return null;
}
double latitude = location.getLatitude();
double longitude = location.getLongitude();
int maxResults = 1;
Geocoder gc = new Geocoder(context, Locale.getDefault());
List<Address> addresses = gc.getFromLocation(latitude, longitude, maxResults);
for (int i = 0; i < addresses.getMaxAddressLineIndex(); i++) {
Log.d("=Adress=",addresses.getAddressLine(i));
}
}
如何根据坐标获取街道名称?
更新(解决方案)
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
try {
List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
if (addresses != null) {
Address returnedAddress = addresses.get(0);
StringBuilder strReturnedAddress = new StringBuilder();
for (int i = 0; i < returnedAddress.getMaxAddressLineIndex(); i++) {
strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("");
}
et_lugar.setText(strReturnedAddress.toString());
}
else {
et_lugar.setText("No Address returned!");
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
et_lugar.setText("Canont get Address!");
}
谢谢
docs提到了getThoroughfare()
方法,可能为空。我会先试试看。如果为 null,那么我会尝试从 getAddressLine()
中获取一些有用的东西。您可能无法获得所有情况下的街道名称。
首先,您的 phone 支持定位吗?您还需要 post 错误,以便我们知道真正的问题是什么
假设您的 phone 支持位置,请尝试使用 getAdressLine() :
List<Address> addresses = gc.getFromLocation(latitude, longitude, 1);
Log.d("=Adress=",addresses.get(0).getAddressLine(0));
这里的问题是从具有地址 class 结构的列表中获取您想要的内容
解决方案
Geocoder geocoder = new Geocoder(this, Locale.getDefault());
try {
List<Address> addresses = geocoder.getFromLocation(LATITUDE, LONGITUDE, 1);
if (addresses != null) {
Address returnedAddress = addresses.get(0);
StringBuilder strReturnedAddress = new StringBuilder();
for (int i = 0; i < returnedAddress.getMaxAddressLineIndex(); i++) {
strReturnedAddress.append(returnedAddress.getAddressLine(i)).append("");
}
et_lugar.setText(strReturnedAddress.toString());
}
else {
et_lugar.setText("No Address returned!");
