I am using the check box in ListActivity.I doesn't know how to update the checkbox in server.
Now I came up with the result for checked item is unchecked and save means it will save(or update) the server.But in unchecked item checked means not save(or not update) the server.
Rsvp_EngagementMeals.java:
public class Rsvp_EngagementMeals extends ListActivity
{
#Override
checkstatus=new Hashtable<Integer,String>();
status=new ArrayList<String>();
veg =Rsvp_Meals.veg;

httpclass obj = new httpclass();
result = obj.server_conn(user_url);
if (result != null)
{
token = new StringTokenizer2(result, "");
}
value = new ArrayList<String>();
while (token.hasMoreTokens())
{
value.add(token.nextToken());
}
value.add(Integer.toString(value.size()));
Integer k=null;
table=new Hashtable<Integer,ArrayList<String>>();
itemId = new ArrayList<String>();
str2 = new ArrayList<String>();
str3 = new ArrayList<String>();
stritem = new ArrayList<String>();

int id=0,c=0,n=value.size();
for(int j=0; j<n; j++)
{
z = value.get(j);
String[] mystring = z.split("<br>");
int arraysize = mystring.length;
for(int a=0; a<arraysize-1;a++)
{
str2.add(mystring[0]);
}
}
for(int g=0; g<str2.size();g++)
{
String name = str2.get(g);
token2 = new StringTokenizer2(name, "|", false);
while (token2.hasMoreTokens())
{
vegitems.add(token2.nextToken());
}
}
for(int x=1;x<vegitems.size();x++)
{
itemId.add(vegitems.get(x));
x=x+1;
stritem.add(vegitems.get(x));
x=x+1;
status.add(vegitems.get(x));
}
setListAdapter(new IconicAdapter(this));
save.setOnClickListener(new OnClickListener()

label.setText(stritem.get(position));
CheckBox check=(CheckBox)row.findViewById(R.id.check);
check.setId(Integer.parseInt(itemId.get(position)));

check.setChecked(true);
;
check.setOnCheckedChangeListener(new OnCheckedChangeListener()

return (row);
}
}
This is my full code.How to change the status in check box.I want result for when I update the check box its save the server and after I view the list the updated item view my checkbox.
The only bug that i could point was the spelling of false in your if statement:
Change this code:
if(status.get(position).equals("False"))
To this code:
if(status.get(position).equals("false"))
hope this works!

I am working on an app in android studio.
My app has a listview, whiche has Edittext , textview and checkbox in its row.
my proplem is when I have more than five items in my listvew, the listview lost focus, for example: when I press on checkbox on the 6th item , the textview shows me the name from the first item.
I wish I could explain my proplem very well.
This is my adapter:
public AdapterListView(Context context, int resource, ArrayList<ObjectPeople> arraypeople) {

I think the error is the way your arrayPeople List is being populated, if you say the sixth item gets you the first you can try reversing the order with
Collections.reverse(arrayPeople);
you can place this line of code below your holder.cbm.setOnClickListener on your adapter
Hope it helps.
I have a listview that clicking on an element shows a DialogFragmen with several options, options that take the user will be shown in the item of listview TextView and I get the following error in execution:
Activity app.gepv.Inventario has leaked IntentReceiver com.immersion.android.haptics.HapticFeedbackManager$HapticFeedbackBroadcastReceiver#426e94b8 that was originally registered here. Are you missing a call to unregisterReceiver()?
Enter the code that I think is important, if you need anything else edit the question :)
This is mi DialogFragment:
final String[] items= equiDisp.toArray(new String[equiDisp.size()]);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Asigne equipo/equipos:")
.setOnKeyListener(new Dialog.OnKeyListener(){
public boolean onKey(DialogInterface arg0, int keyCode,KeyEvent event) {
// TODO Auto-generated method stub
if (keyCode == KeyEvent.KEYCODE_BACK)
{
finish();
//dialog.dismiss();
actualizarDisplay();
}
return true;
}
})
.setMultiChoiceItems(items, null, new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog, int item, boolean isChecked) {
Log.i("Dialogos", "Opción elegida: " + items[item]);
if(isChecked)
{
marcado.add(items[item]);
Log.i("Dialogos", "Marcado: " + items[item]);
obras.get(pulsado).equiA.add(Integer.parseInt(items[item]));
for( int k=0; k< obras.get(pulsado).equiA.size(); k++)
{
Log.i("Dialogos", "Equipos: " + obras.get(pulsado).equiA.get(k) );
}
}
}
});
So far everything is running well because I check with Log.i
This is the function ActualizarDisplay():

In my android application, I have a list in fragment using an adapter which extends ArrayAdapter. Whenever you hold a row item for long you can delete that row by clicking Yes on an alert-dialogue. But when you click Yes, last row seems to be deleted. When you close that fragment and come back on it then the view is fine with proper row deleted. After debugging for so many days I am unable to fix this.Can anyone please figure out whats wrong ?
Thanks in advance.

You can try to re-instantiate the duasAdapter
duasAdapter = new DuasListAdapter(your_context_here, duas);
instead of
duasAdapter.clear();
if (duas.size() > 0) {
for (String object : duas) {
duasAdapter.insert(object, duasAdapter.getCount());
}
}
duasAdapter.notifyDataSetChanged();
You are using setOnLongClickListener() on your view, use setOnItemLongClickListener() instead.
Hi I am working with android application which is having custom listview. The items in listview around 3000. My problem is after loading items when scrolling it makes outOfMemory Error.
I am using Base Adapter and Each item having One Checkbox and four textviews.
Here is my code. Please let me know the solution.

I also tried with View Holder but still loading slow. Please tell the solution how to solve this.
You need to reuse view paremeter from View getView(final int position, Vie view, ViewGroup parent) and if it's not null, then You don't need to inflate again.
Use ViewHolder pattern;
remove loop for (int dd = 0; dd < arrayListFirstName.size(); dd++) from getView;
Try simplify layout for list items;
Seems arrayListFirstName.size() can be simplified (e.g. use some variable to avoid size() calls)
Do profiling in order to know exactly what is slow downs You scrolling (It might be enough to profike only getView())
Also, check out this video from Google I/O for more details on how to make ListViews in a right way.
