POListView with custom ArrayAdapter and custom object
text
Body
copied!<p>Here are the background details of my app:</p> <ul> <li>Using a FragmentPagerAdapter in my main activity to show couple of different fragments.</li> <li>For one of my fragments, I am using a ListView that is populated by a custom ArrayAdapter that is using a custom object class, in this case "Deal".</li> <li>Using an ArrayList passed into the custom ArrayAdapter.</li> </ul> <p>What I basically am stuck on: <strong>when I click any "deal" on the ListView fragment page, I want to go to another activity and pass in the info from the specific Deal object. So, if I click Deal 1, I want to pass in the Deal 1 object to the new activity for it's info. If I click on Deal 2, I want to pass in the Deal 2 object to the new activity for it's info. I am unsure what to put in the onItemClickListener.</strong></p> <p>Please note, the ArrayList will get it's object from an external source later, just adding in the test subjects for now. Will I need to use the ArrayAdapter to pass in the information to the new activity page?</p> <p><strong>DealsFragment</strong></p> <pre><code>public class DealsFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_show_deals, container, false); ListView listView = (ListView)view.findViewById(R.id.dealsListView); // Sample set of data passed to adapter for testing purposes ArrayList<Deal> all_deals = new ArrayList<Deal>(); all_deals.add(new Deal("Deal 1", R.drawable.test_image, 389, 700, 750, 500)); all_deals.add(new Deal("Deal 2", R.drawable.test_image, 20, 80, 1800, 1500)); all_deals.add(new Deal("Deal 3", R.drawable.test_image, 1932, 2000, 75, 60)); all_deals.add(new Deal("Deal 4", R.drawable.test_image, 198, 450, 450, 350)); all_deals.add(new Deal("Deal 5", R.drawable.test_image, 60, 70, 1500, 1100)); // Sets up adapter to pass data into XML DealAdapter adapter = new DealAdapter(getActivity(), R.layout.listview_item_row, all_deals); // TO ADD HEADER ROW BACK IN // View header = (View)inflater.inflate(R.layout.listview_header_row, null); // LV.addHeaderView(header); listView.setAdapter(adapter); listView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Intent intent = new Intent(getActivity(), DealPage.class); startActivity(intent); } }); return view; } } </code></pre> <p><strong>DealAdapter</strong></p> <pre><code>public class DealAdapter extends ArrayAdapter<Deal> { Context context; int layoutResourceId; ArrayList<Deal> data = null; public DealAdapter(Context context, int layoutResourceId, ArrayList<Deal> data) { super(context, layoutResourceId, data); this.layoutResourceId = layoutResourceId; this.context = context; this.data = data; } static class ViewHolder { ImageView imgDealImage; TextView txtDescription; TextView txtSupporters; TextView txtRegularPrice; TextView txtDiscountPrice; } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder = null; if(convertView == null) { LayoutInflater inflater = ((Activity)context).getLayoutInflater(); convertView = inflater.inflate(layoutResourceId, parent, false); holder = new ViewHolder(); holder.imgDealImage = (ImageView)convertView.findViewById(R.id.imgDealImage); holder.txtDescription = (TextView)convertView.findViewById(R.id.txtDescription); holder.txtSupporters = (TextView)convertView.findViewById(R.id.txtSupporters); holder.txtRegularPrice = (TextView)convertView.findViewById(R.id.txtRegularPrice); holder.txtDiscountPrice = (TextView)convertView.findViewById(R.id.txtDiscountPrice); convertView.setTag(holder); } else { holder = (ViewHolder)convertView.getTag(); } int image = data.get(position).getImage(); String description = data.get(position).getDescription(); int currentSupporters = data.get(position).getCurrentSupporters(); int maxSupporters = data.get(position).getMaxSupporters(); int regularPrice = data.get(position).getRegularPrice(); int discountPrice = data.get(position).getDiscountPrice(); holder.imgDealImage.setImageResource(image); holder.txtDescription.setText(description); holder.txtSupporters.setText(String.valueOf(currentSupporters + " / " + maxSupporters + " Supporters")); holder.txtRegularPrice.setText(String.valueOf("$" + regularPrice)); holder.txtRegularPrice.setPaintFlags(holder.txtRegularPrice.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG); holder.txtDiscountPrice.setText(String.valueOf("$" + discountPrice)); return convertView; } } </code></pre>
