Removing a row in ListView [android Application]

Question

How can I delete a row in listview after pressing YES button from alertDialog buttons?!

in my code Cancel is a button in row I want if i press it, it should do two things:

Show me alertDialog : i did that by calling a function ShowDialogCancel() ,
After pressing: YES in this alertDialog ==> the row should be removed !!

I tried with many ways but it delete the row before I press YES button in the alertDialog

any Suggestion

My adapter class:

public class MyCasesListAdapter extends BaseAdapter {
    private MyPage myPage;
    private List<MyCaseClass> listOfCases;
    private Activity parentActivity;

    // TODO test
    MyCaseClass entry;

    // TODO delete it not imp.
    public MyCasesListAdapter() {

        super();

    }

    public MyCasesListAdapter(MyPage mypage, List<MyCaseClass> listOfCaseParameter, Activity parentActivity) {
        this.myPage = mypage;
        this.listOfCases = listOfCaseParameter;
        this.parentActivity = parentActivity;
    }
...
    public View getView(int position, View convertView, ViewGroup viewGroup) {

         entry = listOfCases.get(position);
         //this.getitem(position)
        if (convertView == null) {

            LayoutInflater inflater = (LayoutInflater) myPage
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.mypage_row, null);
          }


        // this is row items..
        // Set the onClick Listener on this button
        Button ConfExpandRegion = (Button) convertView.findViewById(R.id.expand);
        Button Cancelb = (Button) convertView.findViewById(R.id.cancelCase);
        TextView tvCase = (TextView) convertView.findViewById(R.id.mypage_name);

        // To be a clickable button
        ConfExpandRegion.setFocusableInTouchMode(false);
        ConfExpandRegion.setFocusable(false);


        ConfExpandRegion.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub
                myPage.ShowingDialogExpand();
            }
        });

        // To be a clickable button
        Cancelb.setFocusableInTouchMode(false);
        Cancelb.setFocusable(false);
        Cancelb.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub
                entry = (MyCaseClass) v.getTag();
                int caseid= entry.getID();
                myPage.ShowingDialogCancel(caseid);

                Toast.makeText(myPage, "inside calling", 0).show();

                //MyCaseClass entry = (MyCaseClass) v.getTag();
                //listOfCases.remove(entry);

                // listPhonebook.remove(view.getId());
                notifyDataSetChanged();
            }
        });

        // Set the entry, so that you can capture which item was clicked and
        // then remove it
        // As an alternative, you can use the id/position of the item to capture
        // the item
        // that was clicked.
        ConfExpandRegion.setTag(entry);
        Cancelb.setTag(entry);

        // btnRemove.setId(position);

        return convertView;
    }

    public void onClick(View view) {
        MyCaseClass entry = (MyCaseClass) view.getTag();
        listOfCases.remove(entry);
        // listPhonebook.remove(view.getId());
        notifyDataSetChanged();

    }


}

From my page class:

public void  ShowingDialogCancel(){
        final AlertDialog alertDialog2 = new AlertDialog.Builder(this).create();
        alertDialog2.setTitle("Conformation?");
        alertDialog2.setMessage("Are you sure you want to cancel x cases?");


        alertDialog2.setButton("Yes", new DialogInterface.OnClickListener() {
               public  void onClick(DialogInterface dialog, int which) {

                     CancelMsg = "Case_ID cancel";


                   if (!b) {
                        try {
                            // Should write server number here + the chatting must be pushed above 
                            sendSMS("0000", CancelMsg);
                            Toast.makeText(MyPage.this, "Cancelation request sent", Toast.LENGTH_LONG)
                                    .show();

                        } catch (Exception e) {
                            // TODO Auto-generated catch block
                            Toast.makeText(MyPage.this, e.getMessage(),
                                    Toast.LENGTH_LONG).show();
                        }

                    }
                   }
            });

            alertDialog2.setButton2("No", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int which) {
                // here you can add functions
                // Do nothing 

                   Toast.makeText(MyPage.this, "inside No", 0)
                    .show();


               }
            });

            alertDialog2.setIcon(android.R.drawable.ic_dialog_alert);
            alertDialog2.show();

    }

}

Start variable names in lower case, otherwise they are colored like class names (and by convention instance variable names starts in lowercase). — Chopin, Apr 28 '12 at 19:31

How are you populating your listview? If you are using an array you can remove the data from your array and reload your list view.

If you have the position you want to remove, you can call

listOfCases.remove(position);
notifyDataSetChanged();

i did that and it removed it correctly, but I want this removing happened when the user press YES button in the AlertDialog – Monerah Apr 28 '12 at 19:39
So put the code inside the `DialogInterface.OnClickListener` for the OK button of your dialog. – Jason Robinson Apr 28 '12 at 19:41
So get a reference to the adapter – Jason Robinson Apr 28 '12 at 19:46
can you tell me how can I do that, my full code is here : http://stackoverflow.com/questions/10366126/getting-data-from-listview-with-baseadapter-android-application – Monerah Apr 28 '12 at 19:49

Using the code you have, if you pass references to ShowingDialogCancel(MyCasesListAdapter adapter, View view) then you can add something like:

adapter.onClick(view);

to your "Yes" button.
