Android：随着时间增长/缩小View
||
我有这样的视图布局：
<?xml version=\"1.0\" encoding=\"utf-8\"?>
<RelativeLayout xmlns:android=\"http://schemas.android.com/apk/res/android\"
android:orientation=\"vertical\" android:layout_width=\"fill_parent\"
android:layout_height=\"fill_parent\" android:background=\"@color/light_gray\"
android:padding=\"5dip\">
<View android:id=\"@+id/fixedSpace\" android:layout_width=\"fill_parent\"
android:layout_height=\"50dip\" android:background=\"@color/aqua\"
android:layout_alignParentBottom=\"true\" android:clickable=\"true\"
android:onClick=\"onClickStartAnimation\" />
<View android:id=\"@+id/dynamicSpace\" android:layout_width=\"fill_parent\"
android:layout_height=\"200dip\" android:background=\"@color/lime\"
android:layout_above=\"@id/fixedSpace\" />
<View android:id=\"@+id/remainingSpace\" android:layout_width=\"fill_parent\"
android:layout_height=\"fill_parent\" android:background=\"@color/pink\"
android:layout_alignParentTop=\"true\" android:layout_above=\"@id/dynamicSpace\" />
</RelativeLayout>
