we can find city temp by using this find_Location Class. in which firstly find the city location by use by longitude and latitude in android? And after that use the method SendToUrl to find the temperature by use GoogleXML "https://www.google.com/ig/api?weather="
ReplyDeletepublic void find_Location(Context con)
{
Log.d("Find Location", "in find_location");
this.con=con;
String location_context = Context.LOCATION_SERVICE;
locationManager = (LocationManager)con.getSystemService(location_context);
List<String> providers = locationManager.getProviders(true);
for (String provider : providers)
{
locationManager.requestLocationUpdates(provider, 1000, 0,new LocationListener()
{
public void onLocationChanged(Location location) {}
public void onProviderDisabled(String provider){}
public void onProviderEnabled(String provider){}
public void onStatusChanged(String provider, int status,Bundle extras){}
});
Location location = locationManager.getLastKnownLocation(provider);
if (location != null)
{
latitude = location.getLatitude();
longitude = location.getLongitude();
addr=ConvertPointToLocation(latitude,longitude);
String temp_c=SendToUrl(addr);
}
}
}
public String ConvertPointToLocation(double pointlat,double pointlog) {
String address = "";
Geocoder geoCoder = new Geocoder(con,
Locale.getDefault());
try {
List<Address> addresses = geoCoder.getFromLocation(pointlat,pointlog, 1);
if (addresses.size() > 0) {
for (int index = 0; index < addresses.get(0)
.getMaxAddressLineIndex(); index++)
address += addresses.get(0).getAddressLine(index) + " ";
}
}
catch (IOException e) {
e.printStackTrace();
}
return address;
}
private String SendToUrl(String string) {
// TODO Auto-generated method stub
try{
string=string.replace(" ","%20");
String queryString="https://www.google.com/ig/api?weather="+string;
url= new URL(queryString);
conec= url.openConnection();
stream = conec.getInputStream();
xpp = XmlPullParserFactory.newInstance().newPullParser();
xpp.setInput(stream, null);
int eventType = xpp.getEventType();
while(eventType != XmlPullParser.END_DOCUMENT)
{
if(eventType == XmlPullParser.START_TAG)
{String elementName = xpp.getName();
if("temp_c".equals(elementName))
{
int acount=xpp.getAttributeCount();
for(int x=0;x<acount;x++)
{
xpp.getAttributeValue(x);
String str=xpp.getAttributeValue(x);
return str;
}
}
}
eventType = xpp.next();
}
}
My answer is not totally perfect but Yahoo Weather API may help you. This worked perfectly for me.
ReplyDeleteIn this api you have to select one of the City and then you will get weather updates. However you have to go through the source for extracting your portion.
Hope this helps.
There appears to be a full code example on anddev.org google weather api description which should include everything you require.
