Пользовательский список в диалоге

Question

Я пытаюсь поставить пользовательский ListView в Dialog.Мой код выглядит следующим образом:

dialog = new Dialog(MyWallet.this);

dialog.setContentView(R.layout.emergency_contacts);
dialog.setTitle("Emergency Contacts");
dialog.show();

mAdapter.addInfo("Name");
ListView lv = (ListView) dialog.findViewById(android.R.id.list);
if (lv != null) {
   lv.setAdapter(mAdapter);
}

, а затем мой пользовательский Adapter:

    private class MyCustomAdapter extends BaseAdapter {
    private static final int TYPE_INFO = 1;
    private static final int TYPE_MAX_COUNT = 1;
    private LayoutInflater mInflater;
    private int noteFull = 0;

    public MyCustomAdapter() {
        mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }


    public void addInfo(final String info) {
        mInfo.add(info);
        notifyDataSetChanged();
    }

    @Override
    public int getCount() {
        return mInfo.size();
    }

    @Override
    public String getItem(int position) {
        return mInfo.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public int getItemViewType(int position) {
            return TYPE_INFO;
    }

    @Override
    public int getViewTypeCount() {
        return TYPE_MAX_COUNT;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        System.out.println("getView " + position + " " + convertView);
        ViewHolder holder = null;
        int type = getItemViewType(position);
        if (convertView == null) {
            holder = new ViewHolder();
            switch (type) {
                case TYPE_INFO:
                    convertView = mInflater.inflate(R.layout.emergency_contacts_list, null);
                    holder.name = (TextView)convertView.findViewById(R.id.name);
                    holder.name.setText(mInfo.get(position));
                    break;
            }
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder)convertView.getTag();
            switch(type) {
                case TYPE_INFO:
                    convertView = mInflater.inflate(R.layout.emergency_contacts_list, null);
                    holder.name = (TextView)convertView.findViewById(R.id.name);
                    holder.name.setText(mInfo.get(position));
                    break;
            }
        }
        return convertView;
    }

}

public static class ViewHolder {
    public TextView name;
    public TextView phoneNumber;
    public TextView emailAddress;
}

Код сбой (с держателем NullPointerException на

.name = (TextView) convertView.findViewById (R.id.name);

Я предполагаю, потому что convertView - это не правильное представление. Как мне установить его справа View?

Answer 1

Th NullPointerException появляется потому, что когда вы получаете convertView, который не равен нулю (переработанный) в методе getView(), вместо того, чтобы использовать его, вы накачиваете новый View на место. getView() метод должен быть:

//...
 else {
            holder = (ViewHolder)convertView.getTag();     
                    holder.name.setText(mInfo.get(position));
}
//..

Answer 2

Вот пример кода того, как вы должны делать раздувание макета

    LayoutInflater li = (LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE);
    View vDialogTextSize = li.inflate(R.layout.options_dialog_textsize, (ViewGroup) findViewById(R.id.Custom_Size_Dialog));

Answer 3

Определите свой статический класс внутри MyCustomAdapter. Это работа для вас. Например

public class MyCustomAdapter extends BaseAdapter {

public static class ViewHolder {
public TextView name;
public TextView phoneNumber;
public TextView emailAddress;
}

}
