Get WOEID in Android

Question

I'm developing an app and one of the features I want to include is being able to get the users location and convert it to a WOEID value and then get the weather data from the Yahoo Weather RSS feed. Here's the documentation that states the requirement for the WOEID value: http://developer.yahoo.com/weather/

Answer 1

You can get the WOEID by using the Yahoo! PlaceFinder API. First you need to request an API key, then you can send your request like this:

http://where.yahooapis.com/geocode?q=[search query]&appid=[yourappidhere]

You will get this as a response:

<ResultSet xmlns:ns1="http://www.yahooapis.com/v1/base.rng" version="2.0" xml:lang="en-US">
<Error>0</Error>
<ErrorMessage>No error</ErrorMessage>
<Locale>en-US</Locale>
<Found>1</Found>
<Quality>85</Quality>
<Result>
<quality>85</quality>
<latitude>38.898708</latitude>
<longitude>-77.036369</longitude>
<offsetlat>38.89719</offsetlat>
<offsetlon>-77.036537</offsetlon>
<radius>400</radius>
<name/>
<line1>1600 Pennsylvania Ave NW</line1>
<line2>Washington, DC 20500-0005</line2>
<line3/>
<line4>United States</line4>
<house>1600</house>
<street>Pennsylvania Ave NW</street>
<xstreet/>
<unittype/>
<unit/>
<postal>20500-0005</postal>
<neighborhood/>
<city>Washington</city>
<county>District of Columbia</county>
<state>District of Columbia</state>
<country>United States</country>
<countrycode>US</countrycode>
<statecode>DC</statecode>
<countycode>DC</countycode>
<uzip>20500</uzip>
<hash>4216F67AA1A143E9</hash>
<woeid>12766118</woeid> // This is what you need
<woetype>11</woetype>
</Result>
</ResultSet>

You can parse the response for the <woeid> tag.

Edit:
If you have an EditText and you want to get the weather based on the city you get from his input then you'll have to do this:

String searchQuery = Uri.encode(myEditText.getText().toString());

Now you'll have your search query. So e.g if the user types in:

Hamburg Germany

then this will convert it to:

Hamburg_Germany
