調整大小通過動畫的視圖中的Android

我在我所父佈局的按鈕的活動，則有在我想此父layout.What高度的相對佈局，寬度（100,100）是：調整大小通過動畫的視圖中的Android

當我點擊母版面上的按鈕。然後相對版面從屏幕位置滑到屏幕。
和未來的後篩選當我點擊這個相對佈局它動畫通過調整其寬度高度FILL_PARENT
然後後再次點擊此相對佈局它以動畫方式返回原來的大小說（100,100）

我通過簡單的翻譯動畫實現了任務1。

任務2也是在這裏實現的是我的任務2碼

slide.setLayoutParams(new RelativeLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT)); 

slide.startAnimation(zoom_in);

我這個任務縮放動畫是

<?xml version="1.0" encoding="utf-8"?> 
<set xmlns:android="http://schemas.android.com/apk/res/android" 
android:interpolator="@android:anim/decelerate_interpolator"> 
<scale android:fromXScale="0.5" android:toXScale="1.0" 
    android:fromYScale="0.5" android:toYScale="1.0" 
    android:pivotX="0%p" android:pivotY="0%p" 
    android:duration="800" /> 
</set>

我要做的就是在這個相對佈局我改變用戶點擊這個佈局的佈局參數從100到匹配父項並應用動畫，並且它像魅力一樣工作。

我的問題是我沒有任何線索如何執行任務3對此將高度BTW，我使用以下方法來實現的任務3，但沒有達到:(

slide.setLayoutParams(new RelativeLayout.LayoutParams(200, 200)); 
slide.startAnimation(zoom_exit);

讚賞

任何幫助
