Android : Get list item id and use it outside of OnItemClickListener

I'm having troubles with a specific situation in my OnItemClickListener. I have a button inside a Custom Adapter that isn't working until I tap on the item list.

I need to get a list item ID from a listview and use it outside of listener so I'm doing it like this:

public class MyActivity extends ActionBarActivity {
final Context context = this;

long matchId;
int matchPosition;

Listener: private class listLongClickListener implements android.widget.AdapterView.OnItemLongClickListener { @Override public boolean onItemLongClick (AdapterView parent, View view, int position, long id) {

        matchID = id;
        matchPosition = position;

I want to use id and position in a Button click listener defined in XML so

<Button
                    android:id="@+id/button_plus"
                    android:layout_width="0dp"
                    android:layout_height="match_parent"
                    android:focusable="false"
                    android:focusableInTouchMode="false"
                    android:layout_weight="1"
                    android:onClick="plusItem"/>

And plusItem is:

public void plusItem(View view) {
    final Database db = new Database(getApplicationContext());
    db.open();

    final Cursor cartCursor = db.fetchProducts();
    startManagingCursor(cartCursor);

    cartCursor.moveToPosition(matchPosition);
    int quantity = cartCursor.getColumnIndex("quantity");
    int price = cartCursor.getColumnIndex("price");

    q = cartCursor.getInt(quantity);
    p = cartCursor.getFloat(price);


    if((""+q).equals("99")){
        Toast.makeText(getApplicationContext(), "99 is Max", Toast.LENGTH_SHORT).show();
    } else {
        String id = String.valueOf(matchId);

        int fin = q + 1;
        float tot = fin * p;

        db.editProduct(id, "" + fin, "" + tot);

        final SimpleCursorAdapter cartCursorAdapter = new SimpleCursorAdapter(
                this,
                R.layout.list_item,
                cartCursor,
                new String[]{Database.ProductsMetaData.PRODUCT_PRODUCT_KEY,
                        Database.ProductsMetaData.PRODUCT_PRICE_KEY,
                        Database.ProductsMetaData.PRODUCT_QUANTITY_KEY,
                        Database.ProductsMetaData.PRODUCT_TOTAL_KEY,
                        Database.ProductsMetaData.PRODUCT_VALUE_KEY,
                },
                new int[]{R.id.product,
                        R.id.price,
                        R.id.quantity,
                        R.id.total,
                        R.id.value,
                },
                1);

        cartCursor.requery();

        cartCursorAdapter.changeCursor(cartCursor);
        list.setAdapter(cartCursorAdapter);
    }


}

However, In order to make it do is work I have to tap on the list item first; If I have more than one element in my list and I tap on one of them, then the buttons in the other items works only for that one I tapped on.

I already made another kind-of this and it worked well with a share utility. Any suggestion?
