pass filtered listview item to next activity

Here i am using using BaseAdapter to filter my listview items.when without using search option if i click on my listview item the listView.setOnItemClickListener works well, I mean the item at the clicked position is passed to next activity.But on the filtered result if i click on the item,some other data is passed to next activity..what might be the issue.?can anyone please help me to solve this issue..?

}
public void setDeviceName(String devicename) {

}
}

In onItemClick you are using rowTenDevice.get(position).getDeviceName(). This causes the problem. You need filtered item so create a public method in adapter to get arrayList.get(position).getDeviceName(). As arrayList is filtered list, it will give you required result.
Use following code:-
Replace line :- intent.putExtra("DeviceList", rowTenDevice.get(position).getDeviceName());
With
intent.putExtra("DeviceList", ((RowTenDevice)adapter.getItem(position)).getDeviceName());

how to get selectd code and selected name value from spinner in android

this is my Asynk task am getting data from server and calling in Oncreate method

DistributerName = _obj.getString("DistributerName")
.toString();
stringArray.add(DistributerName);
}
} catch (JSONException e) {
// TODO Auto-generated catch block

}
return null;
}
#Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
if (_jarray1.length() == 0) {
showpopup("All Distributers had already been registered!");
} else {
dataAdapter = new ArrayAdapter<String>(RDistributor.this,
R.layout.spinner_item, stringArray);
// ArrayAdapter<String> dataAdapter = new
// ArrayAdapter<String>(this,R.layout.spinner_item,

dataAdapter
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
// set the ArrayAdapter to the spinner
rolespinner.setAdapter(dataAdapter);
}
pDialog.dismiss();
super.onPostExecute(result);
}
}
this is itemselected of spinner and getting value .
rolespinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
DistributerName=rolespinner.getSelectedItem().toString();
Toast.makeText(RDistributor.this, DistributerName, 10000).show();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
}
i am printing data distributerName in Spinner which is coming from server also distributerCode and spoke code coming from server i want when i select distributor name corresponding i get value of distributor code and spoke code selection of ditributorname from drop down please suggest me how i will achieve this .i am facing issue to get this .

Declare :
HashMap<String, String> spinnerMap = new HashMap<String, String>();
for (int i = 0; i <= _jarray1.length(); i++) {
JSONObject _obj = _jarray1.getJSONObject(i);
SpokeCode = _obj.getString("SpokeCode").toString();
DistributerCode = _obj.getString("DistributerCode")
.toString();
DistributerName = _obj.getString("DistributerName")
.toString();
spinnerMap.put(DistributerName, DistributerCode);
stringArray.add(DistributerName);
}
and spinner item-select Method update this :
rolespinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
// TODO Auto-generated method stub
String to= spinnerMap.get(rolespinner.getSelectedItem());
Toast.makeText(MainActivity.this,
to, 10000);
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
enjoy!!!

I think you need to wrap a object for storing these property.
public class Model {
public String spokeCode;
public String DistributerCode;
.......
}
ArrayList<Model> list = new ArrayList<Model>();
list.add(model);
list.add(model);//
// and so on
//do search
DistributerName=rolespinner.getSelectedItem().toString();
Model searchModel;
for (Model m : list) {
if (m.distributerName.equals(DistributerName)) {
searchModel = m;
break;
}
}

adding data to existing listview

I have created listview using the following code

}
final ListView list1 = (ListView)findViewById(R.id.spacelist);

Now I want to add Item to this existing list.
I am taking data from another activity using intent.
Now one item get added.but next time that get replaced.
Please Help.
Thank you in advance.

You should move the creation of the data outside of the adapter:
list=new ArrayList<SingleRow>();
//putting actual values in array
Resources res=c.getResources();
String[] titles=res.getStringArray(R.array.titles);
int[] images={R.drawable.error,R.drawable.ic_launcher,R.drawable.ic_launcher};
//putting single row in arraylist
for(int i=0;i<3;i++){
list.add(new SingleRow(titles[i], images[i]));
}
Pass the list variable to the adapter and store a reference to it there. Then you can just update the data in the list variable, and call notifyDataSetChanged() on your adapter.
Edit: It seems you want to store the space values, and then retrieve them in the HomeScreen activity later. If I understand the flow of your app correctly, then the createNewSpace class should store the space in SharedPreferences. Then in the HomeScreen activity you should retrieve those from the SharedPreferences, and show them.

You can add data to the adapter and call notifyDataSetChanged().Alternatively, You can create a new adapter and listView.setAdapter(adapter) that adapter.

notifyDataSetChanged is not working

I fetched data in JSON from web service and then i put data into a custom ListView.
On clicking an item of ListView , I open a new Activity. Now I click on "Submit" Button of this activity I go back to the same ListView ,
When I get back to the ListView, I want to change the text of listitem in which I clicked before
I just want to refresh or re-call the activity when it again comes to listticket.java
Right now data is static . I used web services.
listticket.java

Make adapter object globally and initialize once within onCreate and inside onResume() notify to your adapter like below:
Delcaration
MyArrayAdapter adapter;
onCreate
adapter = new MyArrayAdapter(this, listArr);
listView.setAdapter(adapter);
onResume()
adapter.notifyDataSetChanged();

Try this, add, clear and remove calls notifyDataSetChanged itself and you dont have to change your adapter everytime you refresh your information, its expensive.
adapter.clear()
for (Object o : object)
adapter.add(o)

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
