我能够顺利拿到纬度/经度并将其传递到地理codeR得到一个地址。不过,我并不总是得到一个地址返回给用户。好像它需要一对夫妇的尝试?我不知道为什么。
有没有对我来说,在这一点上获得的地址?一个更好的办法
公开名单<地址> getAddresses(){ 地理codeR地理codeR =新的地缘codeR(getApplicationContext(),Locale.getDefault()); 名单<地址>地址=新的ArrayList(); 尝试 { 地址=地理coder.getFromLocation(纬度,经度,1); }赶上(IOException异常E){ e.printStackTrace(); } 返回地址; }
我调用这个方法在这里:
LocationListener的onLocationChange =新LocationListener的(){ 公共无效onLocationChanged(位置LOC){ //设置和显示的经纬度/长时,所提供的位置 字符串经纬度=纬度:+ loc.getLatitude()+长:+ loc.getLongitude(); 纬度= loc.getLatitude(); 经度= loc.getLongitude(); 名单<地址>地址= getAddresses(); 如果(addresses.size()大于0&安培;&安培;地址=空!) 拉链code = addresses.get(0).getPostal code(); Toast.makeText(getApplicationContext(),ZIP code,Toast.LENGTH_SHORT).show(); }解决方案
在我的经验,Google的地理codeR总不工作,我有几个固定点在地图上,当我点击了覆盖它弹出一个敬酒的联系地址为纬度/长,这点不会改变,有时我点击一个相同点10次,但我只让他们的联系地址7。
这是奇怪的,但多数民众赞成事情是这样的,我只是修改我的应用程序,以解决该问题。
I am able to successfully get lat/long and pass it to the geocoder to get an Address. However, I don't always get an address back. Seems like it takes a couple of attempts? I'm not sure why.
Is there a better way for me to obtain the address at this point?
public List<Address> getAddresses(){ Geocoder geocoder = new Geocoder(getApplicationContext(), Locale.getDefault()); List<Address> addresses = new ArrayList(); try { addresses = geocoder.getFromLocation(latitude, longitude, 1); } catch (IOException e) { e.printStackTrace(); } return addresses; }I am calling this method here:
LocationListener onLocationChange=new LocationListener() { public void onLocationChanged(Location loc) { //sets and displays the lat/long when a location is provided String latlong = "Lat: " + loc.getLatitude() + " Long: " + loc.getLongitude(); latitude = loc.getLatitude(); longitude = loc.getLongitude(); List<Address> addresses = getAddresses(); if(addresses.size() > 0 && addresses != null) zipcode = addresses.get(0).getPostalCode(); Toast.makeText(getApplicationContext(), zipcode,Toast.LENGTH_SHORT).show(); }解决方案
In my experience Googles Geocoder doesnt always work, I have a couple of fixed points on the map, when I click on the overlay it pops a toast with the adress for that lat/long, these points do not change, sometimes I click on a same point 10 times, but I only get an adress 7 of them.
It's wierd, but thats the way it is, I just modified my app to work around the problem.
