In the Employee_List activity , you can access the data through index of child and group obtaining from ChildClickListener
myList.setOnChildClickListener(new OnChildClickListener() {
#Override
public boolean onChildClick(ExpandableListView arg0, View arg1, int arg2,
int arg3, long arg4) {
// TODO Auto-generated method stub
//Here You can access the child data by
final EntryItem country = (EntryItem) listAdapter .getChild(arg2, arg3);
//From here you can pass the data through Intent

Unable to get actual position of item after filtering ListView

Here is my MainActivity.java where I define an OnClickListener on the items. Here I am always getting a wrong value of the item after filtering.
If there are 10 items in the ListView then after filtering if I get 3 items and the correct position is like 3,6,9 then I am getting 0,1,2 instead.

here is Adapter class
package com.focusmedica.maadiabetes;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Filter;
import android.widget.Filterable;
import android.widget.ImageView;
import android.widget.TextView;
import java.util.ArrayList;
/**

*/
public class MainAdapter extends BaseAdapter implements Filterable {
ArrayList<DataModel> dataSet;
Context context;
DataModel content;
public ArrayList<DataModel> orig;
public MainAdapter(Context context, ArrayList dataSet) {
super();
this.context = context;
this.dataSet = dataSet;
}
#Override
public int getCount() {
return dataSet.size();
}
#Override
public Object getItem(int position) {
return dataSet.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
class ViewHolder {
private TextView tvChapterName;
private ImageView ivChapterIcon;
}
#Override
public View getView(int position, View view, ViewGroup viewGroup) {
final ViewHolder viewHolder;
if (view == null) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = inflater.inflate(R.layout.card_layout, null);
viewHolder = new ViewHolder();
viewHolder.tvChapterName = (TextView) view.findViewById(R.id.tvChapterName);
viewHolder.ivChapterIcon=(ImageView)view.findViewById(R.id.ivChapterIcon);
view.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) view.getTag();
}
content = dataSet.get(position);
viewHolder.tvChapterName.setText(content.getChapterName());
viewHolder.ivChapterIcon.setImageResource(R.drawable.caticon);
return view;
}
public Filter getFilter() {
return new Filter() {
#Override
protected FilterResults performFiltering(CharSequence constraint) {
final FilterResults oReturn = new FilterResults();
final ArrayList<DataModel> results = new ArrayList<>();
final ArrayList<DataModel> ids = new ArrayList<>();
if (orig == null)
orig = dataSet;
if (constraint != null) {
if (orig != null && orig.size() > 0) {
for (final DataModel g : orig) {
if (g.getChapterName().toLowerCase().contains(constraint.toString())||
g.getChapterName().toUpperCase().contains(constraint.toString()))
results.add(g);
}
}
oReturn.values = results;
}
return oReturn;
}
#SuppressWarnings("unchecked")
#Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
dataSet = (ArrayList<DataModel>) results.values;
notifyDataSetChanged();
}
};
}
public void notifyDataSetChanged() {
super.notifyDataSetChanged();
}
}

To get the "old" position (which is equivalent to the item ID) for an item in the filtered list:
#Override
public long getItemId(int position) {
int itemID;
// orig will be null only if we haven't filtered yet:
if (orig == null)
{
itemID = position;
}
else
{
itemID = orig.indexOf(dataSet.get(position));
}
return itemID;
}
Now use this method with the OnItemClickListener:
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(MainActivity.this, SubActivity.class);
intent.putExtra("position", adapter.getItemId(position) );
startActivity(intent);
}
Note: if you ever need to use notifyDatasetChanged() it might be a good idea to override this method as well:
#Override
public void notifyDatasetChanged()
{
// either this or: orig = dataSet;
orig = null;
super.notifyDatasetChanged();
}

After filtering the 'ArrayList' will add data from the 0th position. So you will get position as 0,1,2. You have to use id instead of position.

Store data which you want to get, in an array and retrieve data select by user using position from the same array in onClick method of listview.

How can I achieve setOnLongClickListener?

I've seen many examples of setOnLongClickListener in a ListView, but I'm using an AndroidHive's ExpandableListView, so it doesn't seem to recognized (error: setOnLongClickListener cannot be resolved to a type). How would I go about making it so that I can use setOnLongClickListener?
ExpandableListView expListView;
...
expListView.setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongChildClick(View v) {
return true;
}
});

Filter on listview disappear listitems while entering something into edittext

I am suffering a weird problem. Actually I have a customize listview in which I am using a filter, everything working fine but when I am typing a text to edittext it disappear the all listitem. I am strange why this going on with me, still I am not a champ of android so need some help. I have seen many similar problems on stackoverflow like this,this,this, and many more, but nothing works in my case. I dont know where i am doing mistake.
My listitem click working fine, So hope it will also work after item search into edittext.
Here is my MainActivity.java :
package com.sunil.listviewmuntilerowdelete;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;

import android.text.TextWatcher;
import android.view.View;
import android.widget.AdapterView;
import android.widget.EditText;
import android.widget.ListView;
public class MainActivity extends Activity {
private String[] myfriendname = null;
EditText edtSearch;
private int[] photo = null;
ListView listView = null;
Context contex = null;
MyListAdapter adapter = null;
private List<MyFriendsSDetails> list = new ArrayList<MyFriendsSDetails>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
contex = this;
listView = (ListView) findViewById(R.id.listview);
edtSearch = (EditText) findViewById(R.id.EditText01);
myfriendname = new String[] { "Sunil Gupta", "Abhishek Tripathi",
"Sandeep Pal", "Amit Verma" };
photo = new int[] { R.drawable.sunil, R.drawable.abhi,
R.drawable.sandy, R.drawable.amit };
final String text[] = { "Sunil is a great man",
"Abhishek is hardworking", "Sandeep is same as amit",
"Amit is unique" };
final Integer[] image = { R.drawable.sunil, R.drawable.abhi,
R.drawable.sandy, R.drawable.amit,
};
for (int index = 0; index < myfriendname.length; index++) {
MyFriendsSDetails details = new MyFriendsSDetails(
myfriendname[index], photo[index]);
list.add(details);
}
adapter = new MyListAdapter(contex, list);
listView.setAdapter(adapter);
listView.setTextFilterEnabled(true);
edtSearch.addTextChangedListener(new TextWatcher() {
#Override
public void onTextChanged(CharSequence cs, int arg1, int arg2,
int arg3) {
// When user changed the Text
MainActivity.this.adapter.getFilter().filter(cs);
}

}
#Override

}
});
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent intent = new Intent(MainActivity.this,
SecondActivity.class);
intent.putExtra("key1", image[position]);
intent.putExtra("key2", text[position]);
startActivity(intent);
}
});
}
}
MyListAdapter.java
package com.sunil.listviewmuntilerowdelete;
import java.util.List;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class MyListAdapter extends ArrayAdapter<MyFriendsSDetails> {
Context context;
LayoutInflater inflater;
List<MyFriendsSDetails> list;
public MyListAdapter(Context context, List<MyFriendsSDetails> list) {
super(context, 0, list);
this.context = context;
this.list = list;
inflater = LayoutInflater.from(context);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
if (convertView == null) {
holder = new ViewHolder();
convertView = inflater.inflate(R.layout.list_item, null);
holder.name = (TextView) convertView.findViewById(R.id.title);
holder.photo = (ImageView) convertView.findViewById(R.id.icon);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.name.setText(list.get(position).getMyfriendname());
holder.photo.setImageResource(list.get(position).getPhoto());
return convertView;
}
private class ViewHolder {
TextView name;
ImageView photo;
}
}
Here is MyFriendsSDetails.java :
package com.sunil.listviewmuntilerowdelete;
public class MyFriendsSDetails {
private String myfriendname = null;
private int photo = 0;
public MyFriendsSDetails(String friendname, int myphoto) {
this.myfriendname = friendname;
this.photo = myphoto;
}
public String getMyfriendname() {
return myfriendname;
}
public void setMyfriendname(String myfriendname) {
this.myfriendname = myfriendname;
}
public int getPhoto() {
return photo;
}
public void setPhoto(int photo) {
this.photo = photo;
}
}
Thanks in advance.

As you are using custom adapter, android cant recognize "MainActivity.this.adapter.getFilter().filter(cs);"
You have to override getFilter() method and do manual changes.
Checkout below code :
#Override
public Filter getFilter() {
Filter filter = new Filter() {
#SuppressWarnings("unchecked")
#Override
protected void publishResults(CharSequence constraint,FilterResults results) {
mDisplayedValues = (ArrayList<HashMap<String, String>>) results.values; // has the filtered values
notifyDataSetChanged(); // notifies the data with new filtered values
}
#Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults(); // Holds the results of a filtering operation in values
ArrayList<HashMap<String, String>> FilteredArrList = new ArrayList<HashMap<String, String>>();
if (mOriginalValues == null) {
mOriginalValues = new ArrayList<HashMap<String, String>>(mDisplayedValues); // saves the original data in mOriginalValues
}
/********
*
* If constraint(CharSequence that is received) is null returns the mOriginalValues(Original) values
* else does the Filtering and returns FilteredArrList(Filtered)
*
********/
if (constraint == null || constraint.length() == 0) {
// set the Original result to return
results.count = mOriginalValues.size();
results.values = mOriginalValues;
} else {
constraint = constraint.toString().toLowerCase();
for (int i = 0; i < mOriginalValues.size(); i++) {
String data = mOriginalValues.get(i).get("name");
if (data.toLowerCase().startsWith(constraint.toString())) {
HashMap<String, String> hmap=new HashMap<String, String>();
hmap.put("name", mOriginalValues.get(i).get("name"));
hmap.put("image", mOriginalValues.get(i).get("image"));
FilteredArrList.add(hmap);
Log.e("DEBUG", "name : "+data);
}
}
// set the Filtered result to return
results.count = FilteredArrList.size();
results.values = FilteredArrList;
}
return results;
}
};
return filter;
}
and use it in your adapter getView()
holder.name.setText(mDisplayedValues.get(position).get("name"));
