Android checkbox + listview issue

Each item of my listview contains a checkbox.

I want the checkbox to be checked/unchecked whenever i click on a row of my listview. Now, the checkbox and the listview item are two separated things, which means i can click on the listview item ("behind" the checkbox) or on the checkbox.

The problem is that if i click on the checkbox, it doesn't trigger the itemClickListener (which is logical since they are separated).

So what i want is for the items and checkboxes to work "as one".

Here are the relevant parts of my code:

Activity:

listView.setAdapter(new FoodTypeAdapter(this, foodTypeList));
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            CheckBox cb = (CheckBox) view.findViewById(R.id.foodType);
            if (cb.isChecked()) {
                intent.putExtra("position", position);
            }
        }
    });

Adapter:

private boolean[] checkBoxState;

public FoodTypeAdapter(Context context, List<FoodType> foodTypeList) {
    this.foodTypeList = foodTypeList;
    inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    checkBoxState = new boolean[foodTypeList.size()];
}

static class ViewHolder {
    protected CheckBox foodType;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    View newView;
    if (convertView == null) {
        newView = inflater.inflate(R.layout.food_type_row, null);
        final ViewHolder viewHolder = new ViewHolder();
        viewHolder.foodType = (CheckBox) newView.findViewById(R.id.foodType);
        newView.setTag(viewHolder);
    } else {
        newView = convertView;
    }

    final ViewHolder holder = (ViewHolder) newView.getTag();

    holder.foodType.setText(foodTypeList.get(position).getName());
    holder.foodType.setChecked(checkBoxState[position]);
    holder.foodType.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            if (((CheckBox) v).isChecked()) {
                checkBoxState[position] = true;
            } else {
                checkBoxState[position] = false;
            }
        }
    });

    return newView;
}

Listview row:

<CheckBox
    android:id="@+id/foodType"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:focusable="false"
    android:clickable="false"
    android:text="Checkbox"
    android:textSize="16sp"/>

I know alot of topics about this already exist but i haven't found one with the same issue...

Help me please!
