Android - update ListView from a fragment to another

I am trying to update listView from another fragment class after i delete an item from listView from current class. For example, i delete a consumer that has an expense, then the expense of that consumer will also be deleted. But consumer and expense is different page that using tab control, which is fragment, when i delete consumer, the expense list is not updated, until i go to previous page, then enter the page again. What can i do to update the expense list when consumer from consumer list is deleted? i heard of using broadcast receiver is able to do that, but how can i implement it in my code? I am new in android, please guide me.Thanks
Here is the code for consumer/participant list :
public class Participant extends ListFragment implements OnClickListener{
Intent intent;
TextView friendId;
Button addparticipant;
String eventId;
ListView lv;
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
EventController controller = new EventController(getActivity());
HashMap<String, String> queryValues = new HashMap<String, String>();
Intent objIntent = getActivity().getIntent();
eventId = objIntent.getStringExtra("eventId");
queryValues.put("eventId", eventId);
ArrayList<HashMap<String, String>> friendList = controller
.getAllFriends(queryValues);
if (friendList.size() != 0) {
lv = getListView();
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
friendId = (TextView) view.findViewById(R.id.friendId);
String valFriendId = friendId.getText().toString();
Intent objIndent = new Intent(getActivity(),
EventPage.class);
objIndent.putExtra("friendId", valFriendId);
startActivity(objIndent);
}
});
lv.setOnItemLongClickListener(new OnItemLongClickListener(){
#Override

View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
friendId = (TextView) arg1.findViewById(R.id.friendId);
registerForContextMenu(getListView());
return false;
}
});
SimpleAdapter adapter = new SimpleAdapter(getActivity(),
friendList, R.layout.view_friend_entry, new String[] {
"friendId", "friendName", "friendSpending" },
new int[] { R.id.friendId, R.id.friendName,
R.id.friendSpending });
adapter.notifyDataSetChanged();
setListAdapter(adapter);
}
}

startActivity(objIntent);
}
#Override

String[] menuItems = getResources().getStringArray(R.array.menu);
for (int i = 0; i < menuItems.length; i++) {

}
}

objIndent.putExtra("friendId", valFriendId);
startActivity(objIndent);
break;
case 1:
String valFriendId2 = friendId.getText().toString();
controller.deleteFriend(valFriendId2);
onResume();
}
return true;
}
#Override
public void onResume() {
super.onResume();
if (getListView() != null) {
updateData();
}
}
private void updateData() {
EventController controller = new EventController(getActivity());

Here is the code for expense list:

}
}

Same scenario with me, if you used FragmentPagerAdapter, Try like this in FirstFragment
private void updateSecondFragment(){
//Way to get TagName which generated by FragmentPagerAdapter
String tagName = "android:switcher:" + R.id.pager + ":" + 1; // Your pager name & tab no of Second Fragment
//Get SecondFragment object from FirstFragment
SecondFragment f2 = (SecondFragment)getActivity().getSupportFragmentManager().findFragmentByTag(tagName);
//Then call your wish method from SecondFragment to update appropriate list
f2.updateList();
}
I got that idea by reading this. Then edit a little !

One way could be creating the methods in the activity that contains the two fragments, and access to the fragments methods from the activity. You can update the database and reload the list in the same method.
For example, In the activity
public void updateFragment2(){ ... }
In fragment 1 you should call:
((ActivityClass)getActivity()).updateFragment2();
In the section "Communicating with the Activity" you can see the explanation of this example:
http://developer.android.com/guide/components/fragments.html

Implement OnClickListener to make Show Context Menu With Short Click not Long Click

I have code like this :
public class ListConActivity extends Activity {
private String[] Distro = { "Ubuntu", "Arch Linux", "Mandriva",
"Open Suse", "IGOS Nusantara", "Linux Mint", "Debian", "Fedora",
"CrunchBang", "Backtrack", "Puppy Linux", "OpenBSD", "Slackware",
"BlankOn", "CentOS" };
private String[] pilihan_menu = { "Tambah Data", "Edit Data", "Hapus Data",
"Kirim Data" };
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Arrays.sort(Distro);
ListView list = (ListView) findViewById(R.id.list);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, Distro);
list.setAdapter(adapter);
registerForContextMenu(list);
}
public void onCreateContextMenu(ContextMenu menu, View tampil,
ContextMenuInfo menuInfo) {
if (tampil.getId() == R.id.list) {
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) menuInfo;
menu.setHeaderTitle(Distro[info.position]);
for (int i = 0; i < pilihan_menu.length; i++) {
menu.add(Menu.NONE, i, i, pilihan_menu[i]);
}
}
}
public boolean onContextItemSelected(MenuItem item) {
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item
.getMenuInfo();
String aksi = pilihan_menu[item.getItemId()];
String nama_pilihan = Distro[info.position];
String isi = String.format("Anda melakukan operasi %s pada pilihan %s",
aksi, nama_pilihan);
Toast.makeText(this, isi, Toast.LENGTH_LONG).show();
return true;
}
}
Its work perfectly showing contextmenu for long click. I changed the code to implement the onclick to be able to open a context menu with a short click.
public class ListConActivity extends Activity implements OnClickListener {
private String[] Distro = { "Ubuntu", "Arch Linux", "Mandriva",
"Open Suse", "IGOS Nusantara", "Linux Mint", "Debian", "Fedora",
"CrunchBang", "Backtrack", "Puppy Linux", "OpenBSD", "Slackware",
"BlankOn", "CentOS" };
private String[] pilihan_menu = { "Tambah Data", "Edit Data", "Hapus Data",
"Kirim Data" };
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Arrays.sort(Distro);
ListView list = (ListView) findViewById(R.id.list);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, Distro);
list.setAdapter(adapter);
registerForContextMenu(list);
list.setOnClickListener(this);
}
public void onCreateContextMenu(ContextMenu menu, View tampil,
ContextMenuInfo menuInfo) {
if (tampil.getId() == R.id.list) {
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) menuInfo;
menu.setHeaderTitle(Distro[info.position]);
for (int i = 0; i < pilihan_menu.length; i++) {
menu.add(Menu.NONE, i, i, pilihan_menu[i]);
}
}
}
public boolean onContextItemSelected(MenuItem item) {
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item
.getMenuInfo();
String aksi = pilihan_menu[item.getItemId()];
String nama_pilihan = Distro[info.position];
String isi = String.format("Anda melakukan operasi %s pada pilihan %s",
aksi, nama_pilihan);
Toast.makeText(this, isi, Toast.LENGTH_LONG).show();
return true;
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
openContextMenu(v);
}
}
Compile success.. But i get force close. Can u help me? thanks dude!

You have set click listener for ListView, not list items. Use setOnItemClickListener and AdapterView.OnItemClickListener

yeaH: do a setOnItemClickListener for listView & in that click method call openContextMenu(view) from Activity class

how to get position in on context item selected in android?

setListAdapter(new ArrayAdapter<String>(this,R.layout.custom_list_item, r));
protected void onListItemClick(ListView list, View view, int position, long id) {
super.onListItemClick(list, view, position, id);
fname=r.get(position);
the above code I got position and name also from array adapter
Like, I need get these all are the values in context menu how can I get it
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.setHeaderTitle("Playlist Option");
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.context_menu, menu);
}
public boolean onContextItemSelected(MenuItem item) {
// here I select the particular list value, that the value position I need that is only I delete that position from server. what are the data i fetch here? and its possible to get position from array list?
}

You can use AdapterContextMenuInfo
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
switch (item.getItemId()) {
case R.id.delete:
String itemName = r.get[(int) info.id]; // This item you will delete
// from list
return true;
}
}

android delete file using context menu

I've got a Listview showing files currently on the SDcard. When you long press the file, a context menu pops up.
My question is: how do I pass in the selected item to the Context Menu in order to delete the file from the list, and is it possible to also delete it from the SDcard using this? My Code is as follows:
public class PlayListActivity extends ListActivity {
// Songs list
public ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.playlist);
ArrayList<HashMap<String, String>> songsListData = new ArrayList<HashMap<String, String>>();
SongsManager plm = new SongsManager();
// get all songs from sdcard
this.songsList = plm.getPlayList();
// looping through playlist
for (int i = 0; i < songsList.size(); i++) {
// creating new HashMap
HashMap<String, String> song = songsList.get(i);
// adding HashList to ArrayList
songsListData.add(song);
}
// Adding menuItems to ListView
ListAdapter adapter = new SimpleAdapter(this, songsListData,
R.layout.playlist_item, new String[] { "songTitle", "songDate" }, new int[] {
R.id.songTitle, R.id.songDate });
setListAdapter(adapter);
// setup ListView item
ListView lv = getListView();
registerForContextMenu(lv);
notifyDataSetChanged();
// listening to single listitem click
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting listitem index
int songIndex = position;
// Starting new intent
Intent in = new Intent(getApplicationContext(),
Bandboxstage.class);
// Sending songIndex to PlayerActivity
in.putExtra("songIndex", songIndex);
setResult(100, in);
// Closing PlayListView
finish();
}
});
}
private void notifyDataSetChanged() {
// TODO Auto-generated method stub
}
#Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
// TODO Auto-generated method stub
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.context_menu, menu);
}
#Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
switch (item.getItemId()) {
case R.id.delete:
Toast.makeText(this, "Delete Called.", Toast.LENGTH_SHORT).show();
deleteFile(info.id);
return true;
case R.id.share:
Toast.makeText(this, "Share Called.", Toast.LENGTH_SHORT).show();
default:
return super.onContextItemSelected(item);
}
}
private void deleteFile(long id) {
// TODO Auto-generated method stub
}
}

Well your answer is in your implementation itself. If you notice, in your onContextItemSelected()
, the following statement brings in the info of the item you have selected in your main listview.
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
You can use info.position to find out the position of your item in the list and then get the object from your ArrayList using songsList.get(info.position).
#Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
switch (item.getItemId()) {
case R.id.delete:
Toast.makeText(this, "Delete Called.", Toast.LENGTH_SHORT).show();
//Make sure songsList is a global variable so that it can be accessed here.
HashMap<String, String> song = songsList.get(info.position);
//Call your delete function to delete the song.
return true;
case R.id.share:
Toast.makeText(this, "Share Called.", Toast.LENGTH_SHORT).show();
default:
return super.onContextItemSelected(item);
}
}

Refer this LINK it passes varialble on long click.
below is the deletefile function
file.delete() will delete the file.
