Création d'un ListView avec des éléments de liste personnalisés par programme dans Android - pas de disposition d'élément de liste XML

Que j'ai vu sur des questions déjà posées, à l'intérieur de la classe personnalisée (par exemple, MyAdapter s'étend ArrayAdapter) ils utilisent toujours gonflé liste xml-page de l'élément. Ce que je souhaite faire, c'est créer tout entièrement à l'aide de Java et pas de XML...

//for example
String[] wordlist = new String[] {a, b, c};

LinearLayout list_item_layout = new LinearLayout(this);
list_item_layout.setId(5000);

TextView listText = new TextView(this);
listText.setId(5001);

listLayout.addView(listText);

ListView list = new ListView(this);

//** QUESTION ** do I declare a programmatic .setAdapter() like this?
//** TAKE NOTE ** I passed 'wordlist' here..
list.setAdapter(new MyAdapter(this, list_item_layout.getId(), listText.getId(), wordlist));

et puis pour MyAdapter...

private class MyAdapter extends ArrayAdapter<String> {

    public MyAdapter(Context context, int resource, int textViewResourceId, String[] strings) {
        super(context, resource, textViewResourceId, strings);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        View v = convertView; //is this the list_item_layout that I passed??
        TextView tv = (TextView) v.findViewById(5001);

        //** QUESTION ** do I pass 'wordlist' again here?
        tv.setText( wordlist[position] );

        return v;
    }
}

Ce qui se passe quand je lance sur mon appareil j'obtiens les erreurs suivantes...

Quelqu'un peut-il expliquer comment le faire par programmation?

Ok, comme je suis toujours bloqué à cette question, je pense que j'ai fait quelques améliorations, mais toujours des messages d'erreur. L'amélioration du code est comme suit..

//wordlist is a global variable
String[] wordlist = new String[] {a, b, c};
//..
//.. inside onCreate...
ListView list = new ListView(this);
list.setAdapter(new MyAdapter(this, R.layout.listitem, R.id.mLargeTextView, wordlist));
//since the ArrayAdapter class needs XML parameters to inflate, I created a dummy layout

maintenant à l'intérieur MyAdapter classe..

private class MyAdapter extends ArrayAdapter<String> {
public MyAdapter(Context context, int resource, int textViewResourceId, String[] strings) {
super(context, resource, textViewResourceId, strings);
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LinearLayout listLayout = new LinearLayout(Main.this);
listLayout.setLayoutParams(new LayoutParams(wrapContent, wrapContent));
listLayout.setId(5000);
TextView listText = new TextView(Main.this);
listText.setId(5001);
listLayout.addView(listText);
listText.setText(wordlist[position]);
return listLayout; 
}
}

Comme vous pouvez le voir, je pense que je dois remplacer getView afin d'afficher ma vue personnalisée c'est donc ce que j'ai fait. Malheureusement, je pense que j'ai mal compris. Voici les erreurs..
