我想要的是在一个活动中显示两个活动。我面临的唯一问题是看起来我无法正确显示布局，因为它只显示带滚动条的第二个布局而不是scrollview的滚动

Answer 1

您的问题出在RelativeLayout下的ScrollView。

尝试将其替换为垂直LinearLayout，并将其2个孩子LinearLayout的权重设为1，如下所示：

<ScrollView
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:fillViewport="true" >

    <LinearLayout
        android:id="@+id/LinearLayout1"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        <LinearLayout
            android:id="@+id/ll"
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:orientation="vertical"
            android:padding="10dip" >

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="10dip"
                android:gravity="center_vertical"
                android:text="YEAR" />

            <ListView
                android:id="@+id/listYear"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="10dip"
                android:background="#B29090"
                android:dividerHeight="1dp" >
            </ListView>
        </LinearLayout>

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_weight="1"
            android:orientation="vertical"
            android:padding="10dip" >

            <TextView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="10dip"
                android:gravity="center_vertical"
                android:text="WEBSITE" />

            <ListView
                android:id="@+id/list"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="10dip"
                android:background="#B29090"
                android:dividerHeight="1dp" >
            </ListView>
        </LinearLayout>
    </LinearLayout>
</ScrollView>

        <LinearLayout
        android:id="@+id/vertical"
        android:layout_width="0dp"
        android:layout_weight="30"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        <ListView
            android:id="@+id/Listbyoperator_listvirtacel"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:divider="#ffffff"
            android:background="#C92B2B"
            android:dividerHeight="1px">

        </ListView>

    </LinearLayout>

    <LinearLayout
        android:id="@+id/horizontal"

         android:layout_width="0dp"
        android:layout_weight="70"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        <ListView
            android:id="@+id/Listbyoperator_detaillist"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" >
        </ListView>

    </LinearLayout>
    </LinearLayout>
