Spinner dans une listView

Bonjour,

Après avoir suivi un tutoriel, je suis dans un impasse puisque je ne parviens pas à l'adapter à mon problème.

Voici le résultat actuel de ce code.

Le but est d'afficher une listView composée de spinner.

Main.xml

Code:

1
2
3
4
5
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" 
    android:layout_width="fill_parent" android:layout_height="fill_parent">
    <ListView android:id="@+id/listView1" android:layout_height="match_parent" android:layout_width="match_parent" />
</LinearLayout>

rowview.xml :

Code:

1
2
3
4
5
6
7
8
9
10
11
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" android:layout_width="match_parent"
    android:layout_height="wrap_content" android:weightSum="1">
    <TextView android:layout_width="wrap_content"
        android:layout_height="match_parent" android:id="@+id/text"
        android:layout_weight="0.5" android:textSize="25sp" />
    <Spinner android:layout_width="0dp" android:layout_height="wrap_content"
        android:id="@+id/spin" android:prompt="@string/choice_prompt"
        android:layout_weight="0.5" />
</LinearLayout>

strings.xm :

Code:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="hello">Hello World, ListViewTestActivity!</string>
    <string name="app_name">ListViewTest</string>
    <string name="choice_prompt">Select a choice</string>
    <string-array name="choices">
        <item>Alpha</item>
        <item>Bravo</item>
        <item>Charlie</item>
    </string-array>
</resources>

ListViewActivity :

public class ListViewTestActivity extends Activity {
 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
 
        ListView listView = (ListView) findViewById(R.id.listView1);
 
        DataHolder data = new DataHolder(this);
        DataHolder data1 = new DataHolder(this);
        DataHolder data2 = new DataHolder(this);
        DataHolder data3 = new DataHolder(this);
        DataHolder data4 = new DataHolder(this);
 
        DataAdapter d = new DataAdapter(this, R.layout.rowview, new DataHolder[] { data, data1, data2, data3, data4 });
 
        listView.setAdapter(d);
    }
}

La classe DataHolder :

public class DataHolder {
 
    private int selected;
    private ArrayAdapter<CharSequence> adapter;
 
    public DataHolder(Context parent) {
        adapter = ArrayAdapter.createFromResource(parent, R.array.choices, android.R.layout.simple_spinner_item);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    }
 
    public ArrayAdapter<CharSequence> getAdapter() {
        return adapter;
    }
 
    public String getText() {
        return (String) adapter.getItem(selected);
    }
 
    public int getSelected() {
        return selected;
    }
 
    public void setSelected(int selected) {
        this.selected = selected;
    }
 
}

public class DataAdapter extends ArrayAdapter<DataHolder> {
 
    private Activity myContext;
 
    public DataAdapter(Activity context, int textViewResourceId, DataHolder[] objects) {
        super(context, textViewResourceId, objects);
        myContext = context;
    }
 
    // We keep this ViewHolder object to save time. It's quicker than findViewById() when repainting.
    static class ViewHolder {
        protected DataHolder data;
        protected TextView text;
        protected Spinner spin;
    }
 
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = null;
 
        // Check to see if this row has already been painted once.
        if (convertView == null) {
 
            // If it hasn't, set up everything:
            LayoutInflater inflator = myContext.getLayoutInflater();
            view = inflator.inflate(R.layout.rowview, null);
 
            // Make a new ViewHolder for this row, and modify its data and spinner:
            final ViewHolder viewHolder = new ViewHolder();
            viewHolder.text = (TextView) view.findViewById(R.id.text);
            viewHolder.data = new DataHolder(myContext);
            viewHolder.spin = (Spinner) view.findViewById(R.id.spin);
            viewHolder.spin.setAdapter(viewHolder.data.getAdapter());
 
            // Used to handle events when the user changes the Spinner selection:
            viewHolder.spin.setOnItemSelectedListener(new OnItemSelectedListener() {
 
                @Override
                public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
                    viewHolder.data.setSelected(arg2);
                    viewHolder.text.setText(viewHolder.data.getText());
                }
 
                @Override
                public void onNothingSelected(AdapterView<?> arg0) {
                }
 
            });
 
            // Update the TextView to reflect what's in the Spinner
            viewHolder.text.setText(viewHolder.data.getText());
 
            view.setTag(viewHolder);
 
            Log.d("DBGINF", viewHolder.text.getText() + "");
        } else {
            view = convertView;
        }
 
        // This is what gets called every time the ListView refreshes
        ViewHolder holder = (ViewHolder) view.getTag();
        holder.text.setText(getItem(position).getText());
        holder.spin.setSelection(getItem(position).getSelected());
 
        return view;
    }
}

Le soucis est que je ne parviens pas à adapter ce code avec ma propre liste de Strings (et non des Strings présents dans le fichier xml)

Merci d'avance.
