Question

I don’t really know where to begin asking this question, so I’ll just try to describe my problem the best I can…I’m currently working on a ListView with a custom List Adapter that inflates 2 text Views and a checkBox. One textView is a description of the option, where the other textView is saved for when I need to use it to display data. When a user clicks on an item in the List it will pop up with an editText Dialog box. I got it to save the text and display it, but the problem I’m having is that when it displays the data, it’s not on the correct ListView item… for example: http://www.vbsteven.be/blog/wp-content/uploads/2009/07/screenshotcalllog.png
Say if I wanted to display the information I got from my dialog box in the first slot of the listView. It displays randomly in either the 3rd 2nd or 4th positions. This seems like such a simple problem but I’ve been struggling for a while…

xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">

  <TextView android:id="@+id/rowTextView" 
    android:layout_width="wrap_content" 
    android:layout_height="70dp"
    android:padding="12dp"
    android:textSize="16sp" >
  </TextView>

  <TextView android:id="@+id/alarm_name_text" 
   android:layout_height="wrap_content" 
   android:text="" 
   android:layout_toRightOf="@+id/rowTextView" 
   android:layout_width="fill_parent">
   </TextView>

  <CheckBox android:id="@+id/CheckBox01" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:padding="10dp"
    android:layout_alignParentRight="true" android:layout_marginRight="6sp"
    android:focusable="false">
  </CheckBox>

</RelativeLayout>

Activity:

    @Override
    protected Dialog onCreateDialog(int id) {
        switch (id) {
        case DIALOG_TEXT_ENTRY:

            LayoutInflater mInflater = LayoutInflater.from(this);
            final View textEntryView = mInflater.inflate(
                    R.layout.alert_text_entry, null);
            /*final View textEntryView1 = mInflater.inflate(R.layout.row, null);*/
            final EditText savedText = ((EditText)textEntryView.findViewById(R.id.password_edit));
            final TextView rowSavedText = ((TextView)findViewById(R.id.alarm_name_text));
            return new AlertDialog.Builder(AlarmList.this)
                    .setIcon(R.drawable.alert_icon)
                    .setTitle("Enter your name")
                    .setView(textEntryView)
                    .setPositiveButton("accept",
                            new DialogInterface.OnClickListener() {
                                @Override
                                public void onClick(DialogInterface dialog,
                                        int which) {
                                    String temp = savedText.getText().toString();
                                    rowSavedText.setText(temp);
                                    rowSavedText.setVisibility(0);
                                }
                            })
                    .setNegativeButton("Cancel", new OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {

                        }
                    }).create();
        }
        return null;
    }

If anyone wants to see any other part of my code for helping, please let me know. Thanks in advance!

Heres my list Adapter and data in it :

planets = new Planet[] { new Planet("Turn On Alarm"),
                    new Planet("Alarm Name"), new Planet("Time"),
                    new Planet("Sound"), new Planet("Vibrate"),
                    new Planet("Repeat"), new Planet("Volume Control"),
                    new Planet("Second Alarm") };
        }
        ArrayList<Planet> planetList = new ArrayList<Planet>();
        planetList.addAll(Arrays.asList(planets));


listAdapter = new PlanetArrayAdapter(this, planetList);

/** Custom adapter for displaying an array of Planet objects. */
private class PlanetArrayAdapter extends ArrayAdapter {

    private LayoutInflater inflater;
    public PlanetArrayAdapter(Context context, List<Planet> planetList) {
        super(context, R.layout.row, R.id.rowTextView, planetList);

        // Cache the LayoutInflate to avoid asking for a new one each time.
        inflater = LayoutInflater.from(context);

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // Planet to display
        Planet planet = (Planet) this.getItem(position);


        // The child views in each row.
        CheckBox checkBox;
        TextView textView;
        Spinner mySpinner;


// Create a new row view
            if (convertView == null) {
                convertView = inflater.inflate(R.layout.row, null);

                // Find the child views.
                textView = (TextView) convertView
                        .findViewById(R.id.rowTextView);
                checkBox = (CheckBox) convertView.findViewById(R.id.CheckBox01);
                // Optimization: Tag the row with it's child views, so we don't
                // have to
                // call findViewById() later when we reuse the row.
                convertView.setTag(new PlanetViewHolder(textView, checkBox));

                // If CheckBox is toggled, update the planet it is tagged with.
                checkBox.setOnClickListener(new View.OnClickListener() {
                    public void onClick(View v) {
                        CheckBox cb = (CheckBox) v;
                        Planet planet = (Planet) cb.getTag();
                        planet.setChecked(cb.isChecked());
                    }
                });
            }
            // Reuse existing row view
            else {
                // Because we use a ViewHolder, we avoid having to call
                // findViewById().
                PlanetViewHolder viewHolder = (PlanetViewHolder) convertView
                        .getTag();
                checkBox = viewHolder.getCheckBox();
                textView = viewHolder.getTextView();
            }

            // Tag the CheckBox with the Planet it is displaying, so that we can
            // access the planet in onClick() when the CheckBox is toggled.
            checkBox.setTag(planet);

            // Display planet data
            checkBox.setChecked(planet.isChecked());
            textView.setText(planet.getName());

            return convertView;
        }

Don’t think you can set those textviews from the dialog view. You will have to set them from within your custom list adapter. Get the name from dialog like you are doing, then add the name to your custom adapter’s data set and finally set the adapter again or notifyDataSetChanged().
