            android:paddingRight="@dimen/dimen_2">

</android.support.v4.widget.NestedScrollView>

Answer 1

Use the android:scrollbars attribute.

Such as:

android:scrollbars="vertical"

android:scrollbars="horizontal"

android:scrollbars="vertical|horizontal"

For example:

<android.support.v4.widget.NestedScrollView
    android:id="@+id/foo"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="vertical">

</android.support.v4.widget.NestedScrollView>
