Answer 1

Set the id to:

android:id="@android:id/list"

Like this:

  <ListView
    android:id="@android:id/list"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:divider="#b5b5b5"
    android:dividerHeight="1dp"
    android:listSelector="@drawable/list_selector" />
