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 .

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);

Android: item list click on JSON generated list view - unable to click

Thanks in advance.
SOLUTION FOUND:
add this into onCreate method
list = (ListView) findViewById(R.id.listView1);
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Log.e("item clicks", "selected: " + position);
String item = list.getItemAtPosition(position).toString();
String contactNum = ((TextView)view.findViewById(R.id.listPhone)).getText().toString();
Log.e("phone number", contactNum);
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:" + contactNum));
startActivity(intent);
}
});
thanks to Kunu for the help

Use this on your onCreate()
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int position,
long id) {
Log.e("item clicks", "selected: " + position);
String contactNum = ((TextView)view.findViewById(R.id.listPhone)).getText().toString();
phoneCall(contactNum);
}
});
and don't forget to import import android.widget.AdapterView.OnItemClickListener;
After retrieving the number try this to make a call
public void phoneCall(String number)
{
String phoneCallUri = "tel:"+number;
Intent phoneCallIntent =new Intent(Intent.ACTION_CALL);
phoneCallIntent.setData(Uri.parse(phoneCallUri));
startActivity(phoneCallIntent);
}

to set the itemClickListener use :
listView.setOnItemClickListener(ActivityName.this);
Override the method, and also inside the xml
set the focusableInTouchMode to false, and also focusable to false for the textviews
Hope that helps

in OnCreate list.setOnItemClickListener(new OnItemClickListener() {});and then Add unimplement method
public class MainActivity extends Activity {
ListView lView ;
String[] ara={"a","b","c","d","e","f"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lView=(ListView)findViewById(R.id.listView1);
ListAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,ara);
lView.setAdapter(adapter);
lView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
}});
}
}

android switch intent dynamically

I am trying to create a main menu activity in android which dynamically selects the activity destination from its position on the page.

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_menu);
GridView gridview = (GridView) findViewById(R.id.grid);
gridview.setAdapter(new HomeMenuAdapter());
gridview.setPadding(50, 40, 50, 40);
gridview.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
//Activities That are invoked by the click
String[] mActivitiesIds = {

}
}
public void activateSettings(){

}
public class HomeMenuAdapter extends BaseAdapter {

public int getCount() {
return mThumbIds.length;

}
public long getItemId(int position) {
return 0;
}
// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent) {
TextView tv;
if (convertView == null) {
tv = new TextView(getApplicationContext());
tv.setGravity(Gravity.CENTER | Gravity.BOTTOM);
tv.setPadding(0, 10, 0, 10);
} else {
tv = (TextView) convertView;
}
tv.setCompoundDrawablesWithIntrinsicBounds(0, mThumbIds[position], 0, 0);
tv.setText(mTextIds[position]);
tv.setHeight(300);
tv.setTextColor(Color.WHITE);
return tv;
}
// references to our images
private Integer[] mThumbIds = {
android.R.drawable.ic_menu_add,
android.R.drawable.ic_menu_view,
android.R.drawable.ic_menu_info_details,

}
}
However whatever I do it always says "Cannot Find Activity".
If I change:
String packageName = "com.verscreative.BowlTrack";
String className = mActivitiesIds[position]+".class";
Intent i = new Intent();
i.setClassName(packageName, className);
to for example:
Context packageName = MainMenu.this;
Class<ViewGamesActivity> className = ViewGamesActivity.class;
Intent i = new Intent();
i.setClass(packageName, className);
It works fine, but all options do the same thing!

Thanks to jimpanzer and sherif-elkhatib, I have combined your comments to find the answer.
The Answer is Changing:
String className = mActivitiesIds[position]+".class";
to this:
String className = "com.verscreative.BowlTrack."+mActivitiesIds[position];

I don't think you need to specify the .class
Try this
String className = mActivitiesIds[position];
Otherwise, a more efficient solution would be to have a 2D array as such :
Object[][] mActivitiesIds =
{
{ getString(R.string.menu_launch_0), Activity1.class }
{ getString(R.string.menu_launch_1), Activity1.class }
{ getString(R.string.menu_launch_2), Activity1.class }
{ getString(R.string.menu_launch_3), Activity1.class }
{ getString(R.string.menu_launch_4), Activity1.class }
{ getString(R.string.menu_launch_5) Activity1.class }
};
Then simply use mActivitiesIds[n][1] to get the class...

Android Listview issues in adding data from AsyncTask

and this is what i get in my logcat

The problem is because you're attempting to set an adapter on your list from outside the UI thread. Views in Android can not be modified in a background thread, which in this case, means you can not modify the UI from the doInBackground method of an AsyncTask. So, your method LoadData() can't call the following:
adapter=new LazyAdapter(this, contactList);
list.setAdapter(adapter);
list.setOnScrollListener(new EndlessScrollListener());
You will need to return some data (probably contactList) from your doInBackground() method, and then move the offending code to the onPostExecute() method, which is run on the UI thread.
The key problem noted in the stack trace is:
CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

1. Always keep the UI thread work on the UI thread, and Non-UI work on the Non-UI thread, this became a law from the arrival of the Honey Comb version of Android.
2. From your above logcat, it points to only one thing, that you are trying to do something from the Non-UI thread on the UI thread (The main Dedicated UI thread).
Here it is.... You are calling it on the doInBackground() which is a Non-UI thread.
adapter=new LazyAdapter(this, contactList);
list.setAdapter(adapter);
list.setOnScrollListener(new EndlessScrollListener());
3. Modify the adapter form UI thread, you can do it in onPostExecute()

You are trying to create a view off the main thread class.
As said on this line
07-26 22:26:36.933: E/AndroidRuntime(16353): Caused by:
android.view.ViewRootImpl$CalledFromWrongThreadException: Only the
original thread that created a view hierarchy can touch its views.
Your main problem is here in your asyncTask. You can not create view items that are not in the original thread. What you can do. is to place this lines on your post method not in do background method or outside asynctask class.
// Getting adapter by passing xml data ArrayList
adapter=new LazyAdapter(this, contactList);
list.setAdapter(adapter);
