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 class UpdatesAdapterList extends BaseAdapter {
private Context context;
private ArrayList<HashMap<String,String>> filterData;
private ArrayList<HashMap<String,String>> orignalData;
public ImageLoader imageLoader;
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 long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = LayoutInflater.from(context).inflate(R.layout.listview_updateitem, null);
holder.UpdateTitle = (TextView) convertView.findViewById(R.id.txtUpdatetitle);

If you use ArrayAdapter as your gridview's adapter, you can override getFilter() method and return your own Filter, which is able to filter items according to entered text. See e.g. this link to learn how to work with Filter. Good luck. :-)

I am able to display all data date wise location wise and ....together But i want to Filter data -date wise location means if we check in location wise then it should Print location Only if filter date wise it should display date ..in list please help i have tired much But unable to do this....i have create check Box for select option date wise filter , location wise filter so please check my code if u want i can send complete code .

If you are using EditText to search then you have to write your own filter method..here is an example Custom ListView Search .
you have to change filter method something like this.
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
worldpopulationlist.clear();
if (charText.length() == 0) {
worldpopulationlist.addAll(arraylist);
} else {
for (WorldPopulation wp : arraylist) {
if(isDate)
{
if (wp.getDate().toLowerCase(Locale.getDefault()).contains(charText))
{
worldpopulationlist.add(wp);
}
}else{
if(wp.getLocation().toLowerCase(Locale.getDefault()).contains(charText))
{
worldpopulationlist.add(wp);
}
}
}
}
notifyDataSetChanged();
}

Adapter ListView item click event

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

Log.v("which", Integer.toString(which));
//
if(which == -1) { //Clear all
// new ChannelHandler().execute(apiurl, username, linkid, vw, ctx, channelID);
}
}
}
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

Android, ListView Searching/Filter -> Duplicate entries

If you filter an adapter that has two strings in each item the filter will pass through the adapter twice. This is why you have multiples. If you had three strings in each you could possibly get three duplicate items.
One solution I found online was to create a custom SimpleAdapter and check for duplicates before populating your ListView.

My custom listview faced the same problem.
The superclass of listview doesn't know that you've changed the size when you have filtered. This means getCount() will return the original size of the array, which is understandably larger than your filtered array. So you must override getCount() function to return the size of filtered array, not the original array. After that, duplicated items gone.
#Override
public int getCount() {
return filter_array.size();
}
#Override
public Object getItem(int position) {
return filter_array.get(position);
}
