Can anyone advise me on how to pass the values of the selected row in a custom viewList to another activity in android. What i mean is that i have a custom ListView which has 2 textView and a checkbox. When the user checks a checkbox and hits the submit button i want to store the values of the 2 textView fields and pass it along to the next activity. Passing to the activity is not the problem. The problem is i cant figure out how to store the values of the checked row.
The code is pasted below.

Any help will be greatly appreciated.. Thanks!
If you are going to use shared prefs (probably a good idea) - something along these lines might be what you are looking for:
//in caller activity (save shared prefs value) ...
String phone = phoneView.getText().toString();
private SharedPreferences prefs;
prefs = getSharedPreferences("yourPrefName", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
editor.putString("phone", phone);
editor.commit();
//in called activity ...
private SharedPreferences prefs;
prefs = getSharedPreferences("yourPrefName", Context.MODE_PRIVATE);
String phone=prefs.getString("phone", null); //will be null if "phone" not found
Hope this helps ...
There's a few different options that Android provides for storing persistent data. They are documented in the following link: http://developer.android.com/guide/topics/data/data-storage.html
You may want to start with a basic SharedPreferences implementation and go from there.

I'm tired already with my code. I'm writing chat application. My app consist of two activity. First activity has a listview of wich each row contain a last message which was send for the user while a second activity contain the whole conversation. In my app I used socket.io for android. My app works fine. Listview is refresh when a data is receive but when I press back button and then come back to the activity a listview not refresh itself already. In logs console I see that a data has received and "changed" method is called but listview is not refresh. What is wrong in belows code?

you did not have any callback after you back to this activity .
You can either override onResume() method or startActivityForResult and do something in the onAcitvityForResult method.

AS i am new to android, i am not sure if the above code to check for user selection of checkboxes should be done in which section of the fragment? I would actually like to populate this data if the user has selected the Done menu presented on the top right corner but then i am finding it difficult to spend the sparse boolean array from fragment to activity. Is there a way this can be accomplished?
Adding code for the main activity which has the "Done" menu button:
package com.project.iandwe;

In the menu done handler try to get your adapter in this way:
ContactsFragments fragment = (ContactsFragments) getSupportFragmentManager()
.findFragmentByTag("ContactsFragments");
ListView listView = fragment.listView;
ContactSelectAdaptor adapter = (ContactSelectAdaptor)listView.getAdaptor();
If you have the adaptor then your sparseb boolean array is visible.
I want to be able to click on the "username" which will lead me to a new class - SetMed.java. Along with the username, i would like it's ID's to be passed on as well. I have tried using Intent but it does not work. Any help is greatly appreciated.
This is my MainActivity.java
package com.checkbox.main;

import java.util.HashMap;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;

import android.widget.ListView;
import android.widget.Toast;
public class ListView_CheckBoxActivity extends Activity {
//Adapter
CheckboxAdapter listItemAdapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//Buttons and incident response
Button getValue=(Button)findViewById(R.id.get_value);
getValue.setOnClickListener(listener);
//listview
ListView list = (ListView) findViewById(R.id.list);
//Array list to store the data
ArrayList<HashMap<String, Object>> listData=new ArrayList<HashMap<String,Object>>();
String []name={"Diabetes","example","example","example","example"};
String []id={"Insulin, Glucagon, Prandin","example","example","example","example"};
for(int i=0;i<5;i++)
{
HashMap<String, Object>
map=new HashMap<String, Object>();
map.put("friend_image", R.drawable.icon);
map.put("friend_username", name[i]);
map.put("friend_id", id[i]);
map.put("selected", false);
//Add data
listData.add(map);
}
//Adapter
listItemAdapter = new CheckboxAdapter(this, listData);
list.setAdapter(listItemAdapter);
}
//Incident Response
OnClickListener listener=new OnClickListener()
{
#Override
public void onClick(View v) {
Intent intent = new Intent(ListView_CheckBoxActivity.this, SetMed.class);
boolean[] array = new boolean[5];
array[0] = CheckboxAdapter.isChecked();
intent.putExtra("status", array);
HashMap<Integer, Boolean> state =listItemAdapter.state;
String options="Medicine Selected:";
for(int j=0; j<listItemAdapter.getCount(); j++)
{
System.out.println("state.get("+j+")=="+state.get(j));
if(state.get(j)!=null)
{
#SuppressWarnings("unchecked")
