how to search data into json list view?

I am developing an apps. Where i Want to add a search functionality but i failed to do it. I try to search the whole list but my search is work only in one item in the list view.
Here is my MainActivity Code
JSONObject jsonobject;
JSONArray jsonarray;
ListView listview;
ListViewAdapter adapter;
private ProgressBar spinner;
ArrayList<HashMap<String, String>> arraylist;
private long lastPressedTime;
public static String imgURL = "url";
public static String VIDEO_ID = "videoId";
public static String TITLE = "title";
EditText editsearch;

and here is my list view adapter code.

}
#Override

}
#Override
public long getItemId(int position) {
return 0;
}
public View getView(final int position, View view, ViewGroup parent) {
// Declare Variables
TextView country;

inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View itemView = inflater.inflate(R.layout.listview_item, parent, false);
// Get the position

return itemView;
}
private void requestNewInterstitial() {

.addTestDevice("020AC93F90A14C29209AF3CA716FFBD4")
.build();
mPublisherInterstitialAd.loadAd(adRequest);
}
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
data.clear();
if (charText.length() == 0) {
data.add(resultp); // resultp is hashmap
} else {
if (resultp.get(MainActivity.TITLE).toLowerCase(Locale.getDefault())
.contains(charText)) {
data.add(resultp);
}
}
notifyDataSetChanged();
}
}

You should declare one more ArrayList name allData, it always store all objects.
ArrayList<HashMap<String, String>> allOriginalData; // always store all object
ArrayList<HashMap<String, String>> data; // use for store object that display in the ListView
public ListViewAdapter(Context context,
ArrayList<HashMap<String, String>> arraylist) {
this.context = context;
data = arraylist;
allOriginalData = new ArrayList<HashMap<String, String>>(arraylist);
imageLoader = new ImageLoader(context);
}
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
data.clear();
if (charText.length() == 0) {
// search empty -> new data = all original data
data = new ArrayList<HashMap<String, String>>(allData);
} else {
// loop all original data
// check the condition and make the new data for display in ListView
for(int i = 0; i < allOriginalData.size(); i++){
HashMap<String, String> resultA = allOriginalData.get(i);
if (resultA.get(MainActivity.TITLE).toLowerCase(Locale.getDefault())
.contains(charText)) {
data.add(resultA);
}
}
}
notifyDataSetChanged();
}

getting all selected from listview

I have a listview with searchview and multiple selection option.For that i'm trying the following code that is as follows..

my problem is
step-1 : i have selected a contact from the listview.
step-2 : now i have searched for xxx contact and i selected it.
step-3 : now when i press on ok button it is retrieving only xxx contact.
step-4 : It needs to retrieve all the selected contacts from the view
How can i do that help me in solving this.

You can simply make a list of objects and everytime user select an item in list view you add object contained in this view, and go further. If user wants to delete an object just search for it in your list and delete it.

with the help of This link
I have taken the one array and added all the selected items before text changing this solved my problem.

ListView CheckBox getting multi selected on just clicking only one time

I'm trying to use CheckBox in my ListView with an ArrayAdapter. When I select any CheckBox onlytime in the list, multiple entries are selected automatically in a random order. Can anyone please tell how I can avoid this.

in your adapter getView() method set the status of the clicked checkbox in model and call notify data set changed, try that

I added the following lines with my code and it started working fine:
ArrayList<Integer> checkedPositions = new ArrayList<Integer>();
final Integer index = new Integer(position);
holder1.chckbx1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (((CheckBox) v).isChecked()) {
// if checked, we add it to the list
checkedPositions.add(index);
} else if (checkedPositions.contains(index)) {
// else if remove it from the list (if it is present)
checkedPositions.remove(index);
}
}
});
// set the state of the checbox based on if it is checked or not.
holder1.chckbx1.setChecked(checkedPositions.contains(index));

Apply addTextChangedListener on editSearchText
the in onTextChanged method see if matching content is found in database or arrayList or whatever you have.....
like : arrayList.get(i).toString().toLowerCase().contains(editSearchText.getText().toString())

how to update listview item when get new data from server after few seconds

I have facing problem in listview i am getting data from server and after parsing this data i am using custom adpater for showing the data in listview.I want to update the listview item each after 3 seconds and add new data to list.how can it possible.
i am using adapter.notifyDataSetChanged() method but my listview is not updating it is showing the old data that i gets first time.how to show new data in listview that i got each after 3 seconds.i am using the update method like this.
private Handler handler = new Handler();
private Runnable updater = new Runnable() {
public void run() {
/*
* Update the list
*/
//list.clearTextFilter();
getVisitorDetailFromServer();
list.invalidateViews();
adapter.notifyDataSetChanged();
try {
Log.i("UPDATE", "Handler called");
// searchAdapter = getFeed(URL);
adapter.notifyDataSetChanged();
handler.postDelayed(this, 3000);
} catch(Exception e) {
Log.e("UPDATE ERROR", e.getMessage());
}
}
};
Using getVisitorDetailFromServer() i am getting the data.

Simple calling adapter.notifyDataSetChanged() will not work unless you actually update the dataset 'within the adapter class'.
I suspect you are not passing the updated information into your Adapter class. Check to see if the datastructure referenced by your Adapter's getCount() method is the same as the one being updated by the getVisitorDetailFromServer() server.
If that is not the problem, you'll need to post more code.

I was having the same problem. I cleared the list before adding the new data and it resolved
