How it was Implemented

The resources for the icons were gotten from google icons. Commit can be found here

• Handling Searching was a bit tricky but was achieved by using custom Adapter that implemented Searchable Adapter.

• The Search View was instantiated here

         searchView.setOnQueryTextListener(this);            searchView.setOnQueryTextListener(this);
       if (mSearchQuery != null && !mSearchQuery.isEmpty()){
           String s = mSearchQuery;
           searchItem.expandActionView();
           searchView.setQuery(s, false);
            searchView.clearFocus();
        }

• The Fragment implemented a listener which watched for change in the text when the user entered his search query in onQueryTextChange() method. This method contains the filter logic which used a for loop to scan through the List for matching text. The code for this can be found here

• Saving the User search query was very important as i was able to cater for orientation changes in the activity in onSavedInstanceState method and was restored in onCreate method of the activity. This can be found here. Doing this i was able to preserve the fragment it self an the search Query.

• Other Updates included introducing Databinding to the architecture i am already using. i am able to bind views direct with the data and it helped reduced a lot of broiler plate. A FragmentBindingAdapter was introduced to help directly bind the data to the xml. (no more setText() method in our fragment/activity).
