How it works

According to the given location, radius, keyword and mood gives out the most suitable choices for users.

DataParser

The DataParser is used to parse the data from google map.

• You should provide the google map api key and the location you want to search near by.

• You can also assign the time span to determine whether to search again if the given search conditions are the same as before.

• The default time span is 2.0 hours.

• Example:

  DataParser dataParser = new DataParser("AIzaSyA...", "your location", 2.0);
  dataParser.setKeyword(keyWord);
  dataParser.setRadius(radius);
  dataParser.setPlaceType(Places.RESTAURANT);
  dataParser.searchNear();
  JSONObject searchedStores = dataParser.getSearchResult();
  dataParser.close();

  The searching ways:

  // You can invoke this one to get the searching result
  JSONObject searchedStores = dataParser.searchNearBy();
  
  // You can also assign how many times you want to search
  JSONObject searchedStores = dataParser.searchNearBy(3);
  
  // Another way
  dataParser.searchNear();
  
  // Assign the times you want to search
  dataParser.searchNear(3);
  
  // Get all the searching result
  JSONObject searchedStores = dataParser.getSearchResult();

StoreDataQuery

It takes 6 parameters to get the query data.

• Location: The location where query takes part
• radius: Desired radius for searching
• keyword: Like "restaurant", "cafe" and so on
• mood: The mood of the user
• photoWidth: The max width of response photos
• photoHeight: The max height of response photos To use the StoreDataQuery Use the getters defined in the inner class StoresData to get the desired data.

StoresDataQuery storesDataQuery = new StoresDataQuery("成功大學", 1000, "餐廳", Mood.NORMAL, 300, 300);
int[] distance = storesDataQuery.storesData.getDistance();
