android, cannot align icons on the right in listview's row

I am currently working on my first android app. In a listview, I need to have the following organisation in each row: - On the left: one main icon on which takes the whole height of the row - On the middle: 2 texts, one below the other - On the right: 2 icons, one below the other I end up with a row.xml file like this, but that does not work as I expect. Do you know if something obvious is missing in this file ? Thanks a lot, Luc ``` <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:padding="6dip"> <ImageView android:id="@+id/icon" android:layout_width="48px" android:layout_height="48px" android:layout_marginRight="0dip" android:src="@drawable/icon" /> <LinearLayout android:orientation="vertical" android:layout_width="0dip" android:layout_weight="1" android:layout_height="wrap_content"> <TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="0dp" android:layout_weight="1" android:textAppearance="?android:attr/textAppearanceLarge" android:textSize="16dp" android:textStyle="bold" android:text="TITLE" android:paddingLeft="5dp" /> <TextView android:id="@+id/description" android:layout_width="wrap_content" android:layout_height="0dp" android:layout_weight="1" android:textAppearance="?android:attr/textAppearanceSmall" android:textSize="14dp" android:text="DESCRIPTION" android:paddingLeft="5dp" /> </LinearLayout> <LinearLayout android:orientation="vertical" android:layout_weight="1" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_gravity="right"> <ImageButton android:id="@+id/button_modify" android:layout_width="16px" android:layout_height="16px" android:src="@drawable/deleteicon" /> <ImageButton android:id="@+id/button_delete" android:layout_width="16px" android:layout_height="16px" android:src="@drawable/modifyicon" /> </LinearLayout> ```
