Android：即使視圖滾動，如何將廣告對齊到屏幕底部？

Question

我以前問我還一直沒能解決一個問題：

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

我所試圖做的是對準着眼於屏幕的底部，使用一個的RelativeLayout或LinearLayout中，然後在滾動視圖中包裹該佈局以允許在必要時進行滾動（用於更改橫向或小屏幕設備）。

到目前爲止，我發現任何對齊父母底部的東西都很好，只要底部可見即可...但如果底部位於滾動下方，則對齊父母底部的視圖會跳轉到頂部。

對於出現在底部的廣告，這看起來很常見，所以我認爲這是可能的。是嗎？

我不知道是否有一種方法來做到這一點，但這是我用來做這種東西的一個技巧。如果這是你想要什麼：

這是我爲它的代碼：

<?xml version="1.0" encoding="utf-8"?>

    android:layout_marginBottom="50dip"> 
    <TextView android:id="@+id/tvInScroll" android:layout_width="fill_parent"

</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;）它只是利潤一招。
