how do i get the getfilter() function working? or is there any simpler way to implement filtering in my listview? i want to filter based on my PromoName

A Filter has two major components, the performFiltering(CharSequence) method and the publishResults(CharSequence, FilterResults) method. In your PromotionListAdapter, you'll need to implement the Filterable interface then Override the getFilter() method to return a new Filter that has these methods implemented.
The performFiltering(CharSequence) method is where you'll do the bulk of your work. The CharSequence argument is the data which you're filtering on. Here, you'll first want to determine if the list should even be filtered as the base case. Once you've decided to perform the filtering, create a new ArrayList for your filtered dataset (in your case, a new ArrayList>), and loop through your complete set of list items, adding the values that match the filter to your new ArrayList.
The return type for the performFiltering method is FilterResults. FilterResults is a simple object with two variables, int count and Object results. Once performFiltering has created the new ArrayList with the filtered data, create a new FilterResults, setting your new ArrayList as results and the size of that ArrayList as count.
The publishResults(CharSequence, FilterResults) method is called after performFiltering() returns. The CharSequence parameter is the same String you were filtering on. The FilterResults parameter is the return from performFiltering(). In this method, you'll want to set your new ArrayList as the data source for your List and then call notifyDataSetChanged() to update the UI.
In order to implement this, I've had success when my Adapter keeps track of both the original ArrayList of data and a filtered ArrayList of what is currently being shown. Here's some boilerplate code based on your adapter that can help get you started. I've commented above important lines.
public class PromotionListAdapter extends BaseAdapter implements Filterable
{
private Activity activity;
private static LayoutInflater inflater = null;
public ImageLoader imageLoader;
//Two data sources, the original data and filtered data
private ArrayList<HashMap<String, String>> originalData;
private ArrayList<HashMap<String, String>> filteredData;
public PromotionListAdapter(Activity a, ArrayList<HashMap<String, String>> d)
{
activity = a;
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
imageLoader = new ImageLoader(activity.getApplicationContext());
//To start, set both data sources to the incoming data
originalData = d;
filteredData = d;
}
//For this helper method, return based on filteredData
public int getCount()
{
return filteredData.size();
}
//This should return a data object, not an int
public Object getItem(int position)
{
return filteredData.get(position);
}
public long getItemId(int position)
{
return position;
}
//The only change here is that we'll use filteredData.get(position)
//Even better would be to use getItem(position), which uses the helper method (see the getItem() method above)
public View getView(int position, View convertView, ViewGroup parent)
{
View vi = convertView;
if (convertView == null)vi = inflater.inflate(R.layout.item_list_promotion, null);
TextView PromoID = (TextView) vi.findViewById(R.id.PromoID);
TextView PromoName = (TextView) vi.findViewById(R.id.PromoName);
TextView PromoImage = (TextView) vi.findViewById(R.id.PromoImage);
TextView PromoDesc = (TextView) vi.findViewById(R.id.PromoDesc);
TextView PromoCate = (TextView) vi.findViewById(R.id.PromoCate);
TextView PromoContact = (TextView) vi.findViewById(R.id.PromoContact);
TextView PromoDateStart = (TextView) vi.findViewById(R.id.PromoDateStart);
TextView PromoDateEnd = (TextView) vi.findViewById(R.id.PromoDateEnd);
ImageView thumb_image = (ImageView) vi.findViewById(R.id.image_promo);
HashMap<String, String> daftar_promotion = new HashMap<String, String>();
//Get data from filtered Data
//This line can be replaced with:
// daftar_promotion = getItem(position);
daftar_promotion = filteredData.get(position);
PromoID.setText(daftar_promotion.get(Curve.TAG_ID_PROMO));
PromoName.setText(daftar_promotion.get(Curve.TAG_NAMA_PROMO));
PromoImage.setText(daftar_promotion.get(Curve.TAG_LINK_IMAGE_PROMO));
PromoDesc.setText(daftar_promotion.get(Curve.TAG_DESC_PROMO));
PromoCate.setText(daftar_promotion.get(Curve.TAG_CATE_PROMO));
PromoContact.setText(daftar_promotion.get(Curve.TAG_CONT_PROMO));
PromoDateStart.setText(daftar_promotion.get(Curve.TAG_DATES_PROMO));
PromoDateEnd.setText(daftar_promotion.get(Curve.TAG_DATEE_PROMO));
imageLoader.DisplayImage(daftar_promotion.get(Curve.TAG_LINK_IMAGE_PROMO),thumb_image);
return vi;
}
#Override
public Filter getFilter()
{
return new Filter()
{
#Override
protected FilterResults performFiltering(CharSequence charSequence)
{
FilterResults results = new FilterResults();
//If there's nothing to filter on, return the original data for your list
if(charSequence == null || charSequence.length() == 0)
{
results.values = originalData;
results.count = originalData.size();
}
else
{
ArrayList<HashMap<String,String>> filterResultsData = new ArrayList<HashMap<String,String>>();
for(HashMap<String,String> data : originalData)
{
//In this loop, you'll filter through originalData and compare each item to charSequence.
//If you find a match, add it to your new ArrayList
//I'm not sure how you're going to do comparison, so you'll need to fill out this conditional
if(data matches your filter criteria)
{
filterResultsData.add(data);
}
}
results.values = filterResultsData;
results.count = filteredResultsData.size();
}
return results;
}
#Override
protected void publishResults(CharSequence charSequence, FilterResults filterResults)
{
filteredData = (ArrayList<HashMap<String,String>>)filterResults.values;
notifyDataSetChanged();
}
};
}
}
And there you have it! As far as I can tell, you've already implemented the TextWatcher for your inputText EditText set up properly, so adding the getFilter() method and making a few other minor changes to your Adapter should lead you to a solution. I believe you can also create a member variable on your Adapter for your Filter, so you're not creating a new instance of the class each time getFilter() is called, but I copy/pasted this from a previous project of mine and am sure it works this way. Play with it and see what works for you! Hope this helps! And please do comment if you need anything clarified.

you adapter needs to implement Filterable .

Why listview is not refresh after come back to the foreground?

I'm trying to do a chat application with two activities. On the first plan is a short list containing the last sent message in each row. A second activity contain all conversation. I use socket.io and my problem is that, when I click back button and then I come back to my app notifyDataSetChanged() stops working. My app recevie a messages from dialog box from a website which a cooperates with android app. In console log I see that a messages from a website are received and onTaskComplete() method is called but a listview is not refreshing. I read that an adapter loses a reference to a listview after restart an activity but how to see in my code I create a new adapter in onResume() method. I don't understand what I do wrong?
While if I will throw out beyond the condition "mSocket.on("message", onMessage);" then a listview is refresh after come back to app but a messages are multiple as many times as there were returns.
below is my code, please help!

});
}
}
Interface MyListener:
package com.example.seadog.fb_dialog;
import java.util.ArrayList;
public interface MyListener {
ArrayList arrayList = new ArrayList();
void onTaskComplete();
}

If I remember well, when you open a new activity in android, that's something separate from the previous one.
When you press the back button, it just kill the activity you were in and show the previous activity.
Maybe you can try to do what you need when back is pressed in this :
#Override
public void onBackPressed()
{
//Do your things here
}
Hope I helped.

I don't understand what's wrong in this?? please Help me out from this..

I think your problem is in this line:
if (jsonobject.getString("o_username").equalsIgnoreCase(uid)) {
Your 'uid' is "0"
String uid = "0";
So your if statement returning false.

I think you have forgot to setText-->
lvtaskname.setText(itemwod.get(position)); -- here you not getName please check
// lvtaskname.setText(itemwod.get(position).getName); --- check this
lvtaskdetails.setText(itemorder.get(position));
lvtaskremark.setText(item_remark.get(position));
//lvtaskdate.setText(item_date.get(position));

I WANT TO LOAD IMAGES ATLEAST IN THIS BASE... OR ANYOTHER THING...

There are lots of image loading library available for android.
Have a look at these
https://github.com/square/picasso
https://github.com/nostra13/Android-Universal-Image-Loader
https://code.google.com/p/android-query/wiki/ImageLoading
https://android.googlesource.com/platform/frameworks/volley
https://github.com/koush/UrlImageViewHelper
https://github.com/novoda/image-loader

You can use library by square called Picasso
Here is the documentation.
Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);
Here is a custom adapter for a listview having 2 texts and an image
public class CustomArrayAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values1;
private final String[] values2;
public CustomArrayAdapter(Context context, String[] values1, String[] values2) {
super(context, R.layout.some_layout, values1);
this.context = context;
this.values1 = values1;
this.values2 = values2;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
// LayoutInflater inflater = LayoutInflater.from(context);
// View rowView = inflater.inflate(R.layout.some_layout, null);
View rowView = convertView;
if (rowView == null) {
LayoutInflater inflater = LayoutInflater.from(context);
rowView = inflater.inflate(R.layout.some_layout, null);
holder = new ViewHolder();
holder.text1 = (TextView) rowView.findViewById(R.id.firstLine);
holder.text2 = (TextView) rowView.findViewById(R.id.secondLine);
holder.img = (ImageView) rowView.findViewById(R.id.imageView);
rowView.setTag(holder);
}
else {
holder=(ViewHolder)rowView.getTag();
}
holder.text1.setText(values1[position]);
holder.text2.setText(values2[position]);
Picasso.with(rowView.getContext()).load("http://www.9ori.com/store/media/images/8ab579a656.jpg").into(holder.img);
// if (position%2==0) {
// holder.img.setImageResource(R.drawable.correct);
// }
// else {
// holder.img.setImageResource(R.drawable.incorrect);
// }
return rowView;
}
public static class ViewHolder {
public TextView text1, text2;
public ImageView img;
}
}

Use ListActivity inside a Fragment

Here are two codes that I wanted to combine and make it work, I have this navigation drawer which I wanted to put my post comment post inside and enable it to run.
To enable it to run, I will need to make the listActivity runs inside a fragments. It's not possible to extend two activities, so I would like the community to take a look at my code if it can be connect and make it works. This code I got it online.
The HomeFragment.java
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class HomeFragment extends Fragment {

Use a ListFragment for this, you can find the documentation and reference here: http://developer.android.com/reference/android/app/ListFragment.html
you can google examples (e.g: http://www.vogella.com/tutorials/AndroidListView/article.html#listactivity)
