How to set the height of an AlertDialog element?

Question

Currently on an Android 4.3 device. I am using a great answer here . I managed to reduce the font size of AlertDialogindividual elements:

<style name="AlertDialogTheme" parent="android:Theme.Dialog">
    <item name="android:textSize">13sp</item>
</style>

The dialog itself is built using:

ContextThemeWrapper cw = new ContextThemeWrapper( this, R.style.AlertDialogTheme );
AlertDialog.Builder builder = new AlertDialog.Builder(cw);

However, the problem is that the individual height of the elements remains unchanged - in fact there is a fifth element that simply appears when scrolling in the dialog box:

I tried to installdividerHeight , but it just increased the interval. I also set the property layout_marginto 0dpwithout success.

What is the correct style definition for this dialog to reduce the space between labels?

- getView ListView AlertDialog TextView:

ContextThemeWrapper cw = new ContextThemeWrapper(MainActivity.this, R.style.AlertDialogTheme);
AlertDialog.Builder builder = new AlertDialog.Builder(cw);

AlertDialog dialog = builder.create();
dialog.setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(DialogInterface dialogInterface) {
        ListView listView = ((AlertDialog) dialogInterface).getListView();
        final ListAdapter originalAdapter = listView.getAdapter();

        listView.setAdapter(new ListAdapter() {
            @Override
            public int getCount() {
                return originalAdapter.getCount();
            }

            @Override
            public Object getItem(int id) {
                return originalAdapter.getItem(id);
            }

            @Override
            public long getItemId(int id) {
                return originalAdapter.getItemId(id);
            }

            @Override
            public int getItemViewType(int id) {
                return originalAdapter.getItemViewType(id);
            }

            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                View view = originalAdapter.getView(position, convertView, parent);
                TextView textView = (TextView) view;
                //textView.setTextSize(16); set text size programmatically if needed
                textView.setLayoutParams(new AbsListView.LayoutParams(AbsListView.LayoutParams.MATCH_PARENT, 32 /* this is item height */));
                return view;
            }

            @Override
            public int getViewTypeCount() {
                return originalAdapter.getViewTypeCount();
            }

            @Override
            public boolean hasStableIds() {
                return originalAdapter.hasStableIds();
            }

            @Override
            public boolean isEmpty() {
                return originalAdapter.isEmpty();
            }

            @Override
            public void registerDataSetObserver(DataSetObserver observer) {
                originalAdapter.registerDataSetObserver(observer);

            }

            @Override
            public void unregisterDataSetObserver(DataSetObserver observer) {
                originalAdapter.unregisterDataSetObserver(observer);

            }

            @Override
            public boolean areAllItemsEnabled() {
                return originalAdapter.areAllItemsEnabled();
            }

            @Override
            public boolean isEnabled(int position) {
                return originalAdapter.isEnabled(position);
            }

        });
    }
});

dialog.show();
