I'm trying to do Autogrowin/Endless ListView but I have a problem with ArrayAdapter = update after downloading the data.
public class ListShowActivity extends ListActivity {

{
private ArrayList<ShowsList> items = new ArrayList<ShowsList>();
public ShowsAdapter(Context context, int textViewResourceId, ArrayList<ShowsList> items)
{
super(context, textViewResourceId, items);
this.items = items;
}
public void appendList(ArrayList<ShowsList> results)
{
if((results != null) && (results.size() != 0))
{
m_adapter.add(results.get(0));
m_adapter.notifyDataSetChanged();
Log.i("test", "appendList: "+results.get(0).originalTitle);
}
}
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
View v = convertView;
TextView tt = null;
TextView bt = null;
ImageView iv = null;
if (v == null){
LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.list_show_item, null);
tt = (TextView) v.findViewById(R.id.showOriginalTitle);
bt = (TextView) v.findViewById(R.id.showTitle);
iv = (ImageView) v.findViewById(R.id.showPoster);

}
if(bt != null){

{
new DownloadImage().downloadImage(item.poster, iv);

return v;

I pasted code without working Asynctask.
In "theory"^^ everything works (appendList Log return correct value), but i as say i have problem with update ShowsAdapter (Download new image + and insert content to ListView)

Hello to all android folks over there!!
I want to get list of objects from web service and want to display them in list view.Now i am able to fetch those values and collected them in arraylist.But i am facing problem to display them in list view.below is my code.
Using everyones suggestion ,i solved my problem.Thats the spirit of android buddies.I am pasting my answer in UPDATED block.Hope it will be helpful in future.

you can try this:
this is the adapter class code.
public class CustomTaskHistory extends ArrayAdapter<String> {
private Activity context;
ArrayList<String> listTasks = new ArrayList<String>();
String fetchRefID;
StringBuilder responseOutput;
ProgressDialog progress;
String resultOutput;
public String getFetchRefID() {
return fetchRefID;
}
public void setFetchRefID(String fetchRefID) {
this.fetchRefID = fetchRefID;
}
public CustomTaskHistory(Activity context, ArrayList<String> listTasks) {
super(context, R.layout.content_main, listTasks);
this.context = context;
this.listTasks = listTasks;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.list_task_history, null, true);
TextView textViewName = (TextView) listViewItem.findViewById(R.id.textViewName);
LinearLayout linearLayout = (LinearLayout) listViewItem.findViewById(R.id.firstLayout);
//System.out.println("client_id" + _clientID);
//TextView textViewDesc = (TextView) listViewItem.findViewById(R.id.textViewDesc);
//ImageView image = (ImageView) listViewItem.findViewById(R.id.imageView);
if (position % 2 != 0) {
linearLayout.setBackgroundResource(R.color.sky_blue);
} else {
linearLayout.setBackgroundResource(R.color.white);
}
textViewName.setText(listTasks.get(position));
return listViewItem;
}
}
and now in the parent class you must have already added a list view in your xml file so now display code for it is below:
CustomTaskHistory customList = new CustomTaskHistory(TaskHistory.this, task_history_name);
listView = (ListView) findViewById(R.id.listView);
listView.setAdapter(customList);
you can also perform any action on clicking cells of listview.If needed code for it is below add just below the above code:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Intent nextScreen2 = new Intent(getApplicationContext(), SubscribeProgrammes.class);
nextScreen2.putExtra("CLIENT_ID", _clientID);
nextScreen2.putExtra("REFERENCE_ID", reference_IDs.get(i));
startActivity(nextScreen2);
Toast.makeText(getApplicationContext(), "You Clicked " + task_list.get(i), Toast.LENGTH_SHORT).show();
}
});

You need to load the data into the ListView again. You are binding the ListView to an adapter, you need to do it in onConfigurationChanged() method.
When orientation changes the activity reloads again.So you have to override onConfigurationChanged method.
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
//Your Code Here
}
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
//Your Code Here
}
}
create a directory layout-land in the resources copy the your .xml file there align and set the Edittext and Button according to landscape layout .may be it solved your problem if the listview doest not get enough space to show in landscape layout
In onViewCreated(View view, Bundle savedInstanceState) method above you are setting new empty arraylist every time. So the previous items which are loaded are removed from adapter even though it is retained by setRetainInstance(true)
So you should have a Field that holds the arraylist and pass that field to adapter
private ArrayList<ListRowItem> listItems = new ArrayList<>()
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
if (listAdapter==null) {
listAdapter=new ListAdapter(getActivity(), listItems);//pass the Arraylist here
listView.setAdapter(listAdapter);
listAdapter.notifyDataSetChanged();
}
}
Then in private void listView(String response) method, add items to that listview created above as
listItems = new Gson().fromJson(response, listType);
listAdapter.notifyDataSetChanged();

I want load more 7 pages
In your LoadData AsyncTask, in onPostExecute, you always re-create the adapter with new data received, so it does not append the existing data.
What you need to do is add a method to InfoTeacher adapter to append new items to your existing data, and then call that method from onPostExecute if the adapter already exists (adapter != null).
EmptyView in ListView appears on page even though the list is not empty.
(I'm not using ListActivity)
Even when I remove the setEmptyView(...) it makes no change!
What am I supposed to do?

My Adapter is ArrayAdapter.
I have implemented isEmpty and getCount too.
Here is my Adapter:
public class SearchResultArrayListAdaptor extends ArrayAdapter<PropertyObject>{
Context context;
int layoutResourceId; // This is the layout you created for the list items
ArrayList<PropertyObject> items;
public SearchResultArrayListAdaptor(Context context, int layoutResourceId, ArrayList<PropertyObject> items) {
super(context, layoutResourceId, items);
this.items = items;
this.layoutResourceId = layoutResourceId;
this.context = context;
}
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
LayoutInflater inflater = ((Activity) getContext()).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
TextView txtLarge1 =
(TextView)row.findViewById(R.id.listViewSearchResultTxtLarge1);
TextView txtLarge2 =
(TextView)row.findViewById(R.id.listViewSearchResultTxtLarge2);
#Override
public int getCount() {
if (items == null)
return 0;
else
return items.size();
}
#Override
public boolean isEmpty(){
if (items == null || items.size()==0)
return true;
return false;
}
My Activity For List:
public class SearchResultListActivity extends ActionBarActivity implements OnItemClickListener{
static PropertyObject selectedPropertyObject;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent = getIntent();
Bundle bundle=new Bundle();
bundle.putInt("intentionOfOwner", intent.getIntExtra("intentionOfOwner",0));
SearchResultListFragment fragobj=new SearchResultListFragment();
fragobj.setArguments(bundle);
///back button
setContentView(R.layout.activity_search_result_list);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().add(R.id.container, fragobj).commit();
}
}
#Override
public void onItemClick(AdapterView<?> arg0, View textView, int rowNumber, long arg3) {
Intent intent = new Intent(this, PropertyDetailActivity.class);
PropertyObject po = (PropertyObject) arg0.getAdapter().getItem((int)arg3);
intent.putExtra("listingID",po.getID());
startActivity(intent);
}
any guess?
thanks a lot in advance.
I think the problem is around here, not applicable if you are doing lazy list loading
for(int i = 0; i < jsonArray.length(); i++){
JSONObject c = jsonArray.getJSONObject(i);
propertyObject = new Gson().fromJson(c.toString(), new PropertyObject().getClass());
adapter.add(propertyObject);
adapter.notifyDataSetChanged();
}
try like
ArrayList<PropertyObject> items = new ArrayList<PropertyObject>();
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject c = jsonArray.getJSONObject(i);
propertyObject = new Gson().fromJson(c.toString(), new PropertyObject().getClass());
items.add(propertyObject);
}
adapter.items = items;
adapter.notifyDataSetChanged();
It took me two(!) days to figure out my problem.
I have ListView with both onItemClickListener and onScrollListner. If I implement the onScrollListner then no ItemClick actions are fired.
I saw this problem here: setOnScrollListener with setOnItemClickListener and here:Android: cannot set both: setOnItemClickListener setOnScrollListener? with no real solution.
I have also noticed (in the emulator) that when one of the rows (in the ListView) is selected then ItemClick does fire (I assume that it works in not touch mode).
Very frustrating, can anyone think of a solution?
