and xml

   <listview     android:id="@+id/tracknames"     android:layout_width="match_parent"     android:layout_height="98dp"     android:layout_weight="0.74" > </listview> 

how can populate list? how can using code have?

you need create arrayadapter, or subclass of arrayadapter, add data it, , set in listview.
