Question

i have an array from a json feed i know that in the jArray there is one league but i need to work out the count of that array incase a second is added to the feed at a later date. at the moment log cat isn’t logging out “teamFeedStructure” does anyone know what I’m doing wrong or know how to correctly turn the length of an array into a string that i can use in an intent?

heres the code

JSONObject obj = new JSONObject(json);
JSONObject objData = obj.getJSONObject("data");                      
JSONArray jArray = objData.getJSONArray("structure");
//String leagues = jArray.toString();
//Log.v("myapp", "structure" + leagues);
for (int i=0; i < jArray.length(); i++) {    
     JSONObject oneObject = jArray.getJSONObject(i);
     leaguecountArray = oneObject.getJSONArray("league_id");
     for (int l=0; l < leaguecountArray.length(); l++) {     
         if (leaguecountArray.length() == 1) {
             teamFeedStructure = "One";
         }
         if (leaguecountArray.length() == 2) {
              teamFeedStructure = "Two";
         }
         Log.v("myapp", teamFeedStructure);  
      }
}

Why do you need to iterate here:

for (int l=0; l < leaguecountArray.length(); l++)
{    
    if (leaguecountArray.length() == 1){

         teamFeedStructure = "One";
    }
    if (leaguecountArray.length() == 2){

        teamFeedStructure = "Two";
    }
    Log.v("myapp", teamFeedStructure);   
 }

Nevermind how many passes you do the result will still be the same.

Also you can use not English words, but String holding the number you need. Do like that:

teamFeedStructure = String.valueOf(leaguecountArray.length());

Then the value will become "2" for example. In your other activity you can parse it again to integer like that: int number = Integer.parseInt(teamFeedStructure);
