I'm testing both LazyList (LL) and Universal Image Loader (UIL) that I found here. Also I have successfully made some modifications to retrieve the URL's to load from a JSON document. The JSON is from Flickr. I got the url (for obtain photos) and more data like title, description and author from JSON. Before using these image loading tools I passed data to the view with a SimpleAdapter like this:
// Hashmap for ListView
ArrayList<HashMap<String, String>> itemsList = new ArrayList<HashMap<String, String>>();
Then some code to put JSON DATA into itemsList, then
ListAdapter adapter = new SimpleAdapter(this, itemsList,
R.layout.item,
new String[] { TAG_TITLE, TAG_DESCRIPTION, TAG_AUTHOR }, new int[] {
R.id.title, R.id.description, R.id.author });
setListAdapter(adapter);
// selecting single ListView item
ListView list = getListView();
// Launching new screen on Selecting Single ListItem
list.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String title = ((TextView) view.findViewById(R.id.title)).getText().toString();
String description = ((TextView) view.findViewById(R.id.description)).getText().toString();
String author = ((TextView) view.findViewById(R.id.author)).getText().toString();
// Starting new intent
Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
in.putExtra(TAG_TITLE, title);
in.putExtra(TAG_DESCRIPTION, description);
in.putExtra(TAG_AUTHOR, author);
startActivity(in);
}
});
Following this guide. Now that I tried to merged my code with LL or UIL I can't make it work.
Those image loaders uses their own adapter with a GetWiew method. So finally here's the question: How do I pass my own dynamic data to their adapters?
To make it more clear, I want to show info like title, description and author at the right side of the photo instead of "item X" from picture bellow:
Use custom adapter:
public class MySimpleAdapter extends SimpleAdapter {
private List<String> mImageUrls;
public MySimpleAdapter(Context context, List<? extends Map<String, ?>> data, List<String> imageUrls, int resource, String[] from, int[] to) {
super(context, data, resource, from, to);
mImageUrls = imageUrls;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
ImageView imageView = view.findViewById(R.id.my_image);
ImageLoader.getInstance().displayImage(mImageUrls.get(position), imageView);
return view;
}
}
And pass imageUrls
to constructor.
