Answer 1

Try to make your RelativeLayout focusable:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:id="@+id/rl_simple_list_item_header"
    android:orientation="horizontal"
    android:focusable="true"
    android:focusableInTouchMode="true" >

UPDATE

If you want clickable TextView inside your header you can do it this way:

View header = LayoutInflater.from(this).inflate(R.layout.simple_list_item_header, null);
View favorite = header.findViewById(R.id.iv_simple_list_item_header_favorite);

lv_restaurantInformation = (ListView) findViewById(R.id.lv_restaurant_description_information);
lv_restaurantInformation.addHeaderView(header);

favorite.setOnClickListener(this);

And then handle it in onClick method of the Activity:

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    switch (v.getId()) {
    case R.id.iv_simple_list_item_header_favorite:
        Toast.makeText(this, "onClick", Toast.LENGTH_SHORT).show();
        break;

    default:
        break;
    }
}
