Android：即使視圖滾動，如何將廣告對齊到屏幕底部？

Question

我之前曾問過一個我仍然無法解決的問題：

http://stackoverflow.com/questions/3126347/android-relativelayout-how-to-alignparentbottom-when-wrapped-in-a-scrollview

我想要做的是使用RelativeLayout或LinearLayout將視圖對齊到屏幕底部，然后將該布局包裝在滾動視圖中以允許在必要時滾動（對於橫向方向或小屏幕設備的更改）。

到目前為止，我發現任何與父底部對齊的東西都可以很好地工作，只要底部是可見的......但如果底部位於滾動下方，則父母底部對齊的視圖會跳到頂部。

對於出現在底部的廣告來說，這似乎是一種非常常見的設計，所以我認為這是可能的。 是嗎？

我不知道是否有一種方法可以做到這一點，但這是我用來做這種事情的一個技巧。 如果這是你想要的：

這是我的代碼：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:layout_marginBottom="50dip">
    <TextView android:id="@+id/tvInScroll" android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:text="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque vitae metus ac leo ultrices placerat. Curabitur vel ipsum vitae urna ultricies rhoncus.

</ScrollView>

<TextView android:layout_width="wrap_content" android:id="@+id/tvBelowScroll"
    android:text="This is your ads TV" android:layout_height="50dip"
    android:textStyle="bold" android:textSize="18dip"
    android:layout_alignParentBottom="true"></TextView>
</RelativeLayout>

我希望這符合你的希望;）這只是一個有利潤的技巧。
