android:scrollbars="vertical"
android:isScrollContainer="true"

未起作用,用下面的方法:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:fadingEdge="vertical"
    tools:context=".MainActivityFragment"
    >

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content" android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:id="@+id/mainViewLayout"
    android:isScrollContainer="true">



</RelativeLayout>
</ScrollView>
