How do I make this DialogBox pop up on a list item click?

I got an assignment where I have to implement a custom call forwarding system and was looking for ways of doing so. I decided that Androids own call forwarding looked great and decided that I wanted to prompt the user on an item click on the listview. Basically I want this to pop up when the user clicks an item.

this

Here's the code in which I'm trying to implement the dialog box :

public class CallForwardActivity extends ListActivity 
{
String[] settingsLabels = {"Viderestillinger", "Altid", "Optaget", "Ingen svar", "Timeout"};
int position;
@Override
public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  ListView lv = getListView();
  lv.setTextFilterEnabled(true);
  setListAdapter(new ArrayAdapter<String>(this, R.layout.callforward_items, R.id.callforward_item_text, settingsLabels));

  lv.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) 
    {
        // Open Dialog Box with an edittext view for setting the correct number to Call forward
        myTextDialog().show() // ???
    }
  });
}


private Dialog myTextDialog() {
    final View layout = View.inflate(this, R.layout.custom_dialog, null);

    final EditText savedText = ((EditText) layout.findViewById(R.id.myEditText));

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setIcon(0);

    builder.setPositiveButton("Save", new Dialog.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
           String myTextString = savedText.getText().toString().trim();
        }
    });
    builder.setView(layout);
    return builder.create();
 }

How do I go about "calling" this method/showing the dialog?

Use it this way to declare the dialog,

final AlertDialog.Builder builder = new AlertDialog.Builder(context);
                         builder.setView(//your view)
                           .setPositiveButton("Update", new DialogInterface.OnClickListener() {
                            public void onClick(final DialogInterface dialog, final int id) {
                                //update click
                            }
                           })
                           .setNeutralButton("Disable", new DialogInterface.OnClickListener() {
                                public void onClick(final DialogInterface dialog, final int id) {
                                    //disable click
                                }
                               })
                           .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                                public void onClick(final DialogInterface dialog, final int id) {
                                //cancel click
                                }
                               });

And show it in your click listener as follows,

builder.show();

In the function builder.setView() you have to pass for it a view (layout for example) that consist of textview and edittext and button if you want to make it the same as the figure.

If you want to build your own dialog (in an onItemClickListener for example) then the AlertDialog.Builder is a good place to start. For example:

  lv.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) 
    {
        new AlertDialog.Builder(view.getContext())
            .setMessage("Something here")
            .setNegativeButton("Close", null).show();

    }
  });

You can take a look at the docs for AlertDialog here: http://developer.android.com/reference/android/app/AlertDialog.Builder.html
