フラグメントに含まれる ListView があります。リストビューでアイテムをクリックすると、いくつかのコードを実行したいのですが、実行されるコードは、リストのどのアイテムがクリックされたかによって異なります。ListView を含むフラグメントのコードは次のとおりです。

public class ListViewer extends Fragment {
private ListView list;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInsanceState) {
    View v = inflater.inflate(R.layout.activity_list_view, container, false);

    Player player_data[] = new Player[] {
        new Player(R.drawable.bschenn1, "Brayden Schenn", "Age: 21, Drafted 5th overall by LA King in 2009",  "Center - #10"),  
        new Player(R.drawable.giroux, "Claude Giroux", "Age: 25, Drafted 22nd overall by Philadelphia Flyers in 2006", "Center - #28"),
        new Player(R.drawable.hartnell, "Scott Hartnell", "Age: 30, Drafted 6th overall by Nashville Predators in 2000", "Left Wing - #19")
    };

    PlayerAdapter adapter = new PlayerAdapter(getActivity(), R.layout.list_row, player_data);

    list = (ListView)v.findViewById(R.id.list);

    View header = (View)inflater.inflate(R.layout.listview_header_row, null);

    list.addHeaderView(header);
    list.setAdapter(adapter);

    return v;
}
}

アダプターへのコードは次のとおりです。

public class PlayerAdapter extends ArrayAdapter<Player> {
Context context;
int layoutResourceId;
Player data[] = null;

public PlayerAdapter(Context context, int layoutResourceId, Player[] data) {
    super(context, layoutResourceId, data);
    this.layoutResourceId = layoutResourceId;
    this.context = context;
    this.data = data;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View row = convertView;
    PlayerHolder holder = null;

    if (row == null) {
        LayoutInflater inflater = ((Activity)context).getLayoutInflater();
        row = inflater.inflate(layoutResourceId, parent, false);

        holder = new PlayerHolder();
        holder.imageIcon = (ImageView)row.findViewById(R.id.list_image);
        holder.txtplayerName = (TextView)row.findViewById(R.id.title);
        holder.txtageDraft = (TextView)row.findViewById(R.id.artist);
        holder.txtpositionSNum = (TextView)row.findViewById(R.id.duration);

        row.setTag(holder);
    } else {
        holder = (PlayerHolder)row.getTag();
    }
     Player player = data[position];
     holder.imageIcon.setImageResource(player.image);
     holder.txtplayerName.setText(player.playerName);
     holder.txtageDraft.setText(player.ageDraft);
     holder.txtpositionSNum.setText(player.positionSweaterNum);

     return row;
}

static class PlayerHolder {
    ImageView imageIcon;
    TextView txtplayerName;
    TextView txtageDraft;
    TextView txtpositionSNum;
}

}

どんな助けでも大歓迎です。

タッチイベントを検出するには、リストビューにリスナーを追加する必要があります。

list.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() 
{
 public void onItemSelected(AdapterView parentView, View childView, int position, long id) 
 {
    //here you have the position so you can do whatever you want with this item


 }
});

OnItemClickListenerをリストオブジェクトに追加する必要があります。

list.setOnItemClickListener( new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        // TODO Auto-generated method stub  
        }
    });
}
