Question

Answer 1

You can use ListView.addHeaderView(View view).

Note that in this case you should exclude your RelativeLayout from xml and create it in runtime. Also addHeaderView MUST be called before setAdapter.

UPDATE

just extract RelativeLayout to a separate xml file (e.g. header.xml).

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/orderMeal"
        android:layout_marginLeft="20dip"
        android:id="@+id/tv_restaurant_description_orderMeal"
        android:drawableTop="@drawable/order_meal" />
    <TextView 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/favorite"
        android:layout_alignParentRight="true"
        android:layout_marginRight="20dip"

        android:drawableTop="@drawable/favorite"/>
</RelativeLayout>

and then inflate it in the code:

lv_restaurantInformation = (ListView) findViewById(R.id.lv_restaurant_description_information);
lv_restaurantInformation.addHeaderView(LayoutInflater.from(this).inflate(R.layout.header, null));
