Adapter ListView item click event

Adapter ListView item click event - android

Is this ok to do?
#Override
protected void onPostExecute(final ChannelPair p) {
HiddenChannelsListAdapter adapter = new HiddenChannelsListAdapter(p.ctx, p.channelList);
p.lv.setAdapter(adapter);
p.lv.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Log.i("CLICKED ON LV ITEM", "YEA");
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}
Its not actually triggering the event I think. At least no item is Selected?
UPDATE
So I removed the stuff from the asyncTask and added it to a new Thread, so now its all in the same file. But still, I cannot get the clicks from the items

}
}
This part is where the clicks are bound:
((Activity)ctx).runOnUiThread(new Runnable() {
public void run() {
HiddenChannelsListAdapter adapter = new HiddenChannelsListAdapter(ctx, channelList);
ListView lv = (ListView) vw.findViewById(R.id.list);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3)
{
Log.i("CLICKED ON LV ITEM", "YEA");
}
});
}
});

This causes a change on UIthread which should not be called from the background thread. Remeber never to update or notifychange() a listView from the backgound thread

How to implement endless scrolling listview

I am creating an application in which I am parsing data using Json parsing. I've implemented listview and in my response i have totalpage and current page objects,
A new user will get items from the first page. While the user is scrolling through the listview, the list expands with items from the next page (and the next and the next etc.)
this is my response

You can achieve this by using the following library in Github
https://github.com/nicolasjafelle/PagingListView
Simple create your PagingAdapter and add it to com.paging.listview.PagingListView.
You have to implements the new Pagingable interface and its onLoadMoreItems() method. For example:
listView.setHasMoreItems(true);
listView.setPagingableListener(new PagingListView.Pagingable() {
#Override
public void onLoadMoreItems() {
if (pager < 3) {
new CountryAsyncTask(false).execute();
} else {
listView.onFinishLoading(false, null);
}
}
});
Finally you can use the onFinishLoading(boolean hasMoreItems, List newItems) method to update the list.
listView.onFinishLoading(true, newItems);
Also remember to use this package in your layout files:
<com.paging.listview.PagingListView
android:id="#+id/paging_list_view"
android:layout_width="match_parent"
android:layout_height="match_parent"/>

Hello here you can find the nostra library for lazy loading and then you can
implement the following example for lazzy loading
https://github.com/nostra13/Android-Universal-Image-Loader
you can achieve Lazy loading by using the below
code
Lets start the coding about the lazy loading.

For the Example above you need to download the library universal image loader you can download the library ... happy coding :)

you didn't use EndlessListView in your Fragment. As I looked your response, it includes pagination. So, you need to request with page number to use endless scroll.
This is just flow for Endless Listview. If your code still doesn't work, I hope you can learn sample projects after read this messages. I added only parts you need. Thanks
Endless scroll only shows limited data on listview. When user scroll down to bottom, it will get next limited data from server. So you need to add current_page paramater in your request. I don't know exactly your api.
First, you need variable for current_page which initialize with 0
You have to know when to stop. You response has total_page field for that. Save and add validation
Then you need to know when to request next page. For that,you already have codes in onScroll within EndlessListView. That code calculate and tell when user scroll down to bottom and it called
listener.loadData();
to request new data. But you still need to add listener for that. You already have
public void setListener(EndLessListener listener) {
this.listener = listener;
}
You need to create Interface with the name EndlessListener and implements in your fragment. EndlessListener Interface will include loadData() function that request to server. After that you need to add listener for the listview.
endlessListView.setListener(this);

Try Loading data when listview reaches it's end. Implement OnScrollListener in your fragment. Refer this link Android - ListView to load more items when reached end

You MUST use Paging 3 library to resolve all problems in simplest way.

Listview with onscroll event reseting scroll position when radio button in list is clicked

Here is my custom adapter's getView method.
the ListView is in a AlertDialog. And I am filling the ListView with a web service request.
My Problem is that the scroll position is reset to top whenever i select any radio button in the list.
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View row = null;
LayoutInflater inflater = (LayoutInflater) c
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
row = inflater.inflate(R.layout.list_item_dialog_clients, parent,
false);
} else {
row = convertView;
}
RadioButton button = (RadioButton) row
.findViewById(R.id.rbDialogCustomerName);
button.setText(details.get(position).firstname
+ " " + details.get(position).lastname);
button.setChecked(position == selectedPosition);
button.setTag(position);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
selectedPosition = (Integer) v.getTag();
notifyDataSetInvalidated();
}
});
return row;
}

And finally this is my populating method of this dialog.
CustomersDialog dialog = new CustomersDialog(getActivity());
dialog.createDialog();

Try using notifyDataSetChanged(); in place of notifyDataSetInvalidated();

When used custom adapter always try to implement ViewHolder design pattern for ListView performance and use custom filter function instead Filterable implementation :
Custom filter funcation required two array list one is filterable data list and another one is for orignal data list :
public void filter(String constraint) {
filterData.clear();
if (constraint.length() == 0) {
filterData.addAll(orignalData);
}else{
for (HashMap<String,String> row: orignalData) {
if(row.get(Cardiology_updates.UpdateTitle).toUpperCase().startsWith(constraint.toString().toUpperCase())){
filterData.add(row);
}
}
}
notifyDataSetChanged();
}
Example :
et.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable arg0) {
adapter.filter(arg0.toString());
}
#Override
public void beforeTextChanged(CharSequence arg0, int arg1,int arg2, int arg3) {
}
#Override
public void onTextChanged(CharSequence arg0, int arg1, int arg2,int arg3) {
}
});

public UpdatesAdapterList(Context context,ArrayList<HashMap<String, String>> orignalData) {
this.context = context;
this.orignalData = orignalData;
filterData = new ArrayList<HashMap<String,String>>();
filterData.addAll(this.orignalData);
imageLoader = new ImageLoader(this.context);
}
#Override
public int getCount() {
return filterData.size();
}
#Override
public Object getItem(int position) {
return filterData.get(position);
}
#Override

}
public View getView(final int position, View convertView, ViewGroup parent) {

convertView.setTag(holder);
}else{

}
holder.UpdateTitle.setText(filterData.get(position).get(Cardiology_updates.UpdateTitle));

You could probably do something like this
//get your ListView with attached SimpleAdapter
ListAdapter adapter = listView.getAdapter();
for(int i = 0; i < adapter.getCount(); i++) {
String value = ((HashMap<String, String>)adapter.getItem(i)).get("Your_key");
}
But i'm not sure i understand the question correctly, what is it that you want to accomplish exactly? I'm sorry for asking a question here but i'm not allowed to comment yet :/

in the onTextChangedMethod of TextWatcher, write an if condition that - the edittext values is in the list you are inflating in your listview, if yes them add that edittext value to another list and set that list to your adapter. For Example Here is my Code :- ( Just focus on ListView, ArrayList and TextWatcher. Dont mind other code)

use getListview() in list Activity to get List..........
in Oncreate
ListView lv = getListView();
http://www.mkyong.com/android/android-listview-example/
this link has both ways
1- overriding onListItemClick(
2- Setting you listener..

Try this way..
ListView lv = getListView();
lv. storelist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
}
}
this are help you.
Thanks

Override the function onlistitemclick() for this. Here the integer position represents the postion of item that you had pressed
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
super.onListItemClick(l, v, position, id);
.......
}

Try this one
getListView().setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
// TODO Auto-generated method stub
}
});
