May I know why you want to select multiple rows. I mean what exact action you want to perform by selecting multiple rows?

Here is the updated code for you. Please let me know in case you didn't get any code:

Answer 2

You can always use:

yourListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

To choose multiple items, remember that its interface depend on you creating it.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item 
    android:state_pressed="true"
    android:drawable="@color/white" />
<item
    android:state_selected="true"
    android:drawable="@drawable/list_item_bg_selected" />
<item 
    android:drawable="@color/list_bg" />
</selector>
