i have 2 views in a RelativeLayout like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_width="match_parent"
android:layout_height="match_parent" >
<View
android:id="@+id/view1"
android:layout_width="match_parent"
android:layout_height="200dp"
android:background="@drawable/shape_red"/>
<View
android:id="@+id/view2"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_below="@id/view1"
android:background="@drawable/shape_blue"/>
</RelativeLayout>
now, i animate the y property of view1 from 0 to 300. but i want view2 to
change its position according to view1 - because view2 is set to be below
(layout-below) view1.
as this isn't working, i tried to add an onAnimationEnd listener to the
animation. like this:
ObjectAnimator ani = ObjectAnimator.ofFloat(view1, "Y", 200);
ani.setDuration(2000);
ani.addListener(new AnimatorListenerAdapter()
{
@Override
public void onAnimationEnd(Animator animation)
{
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT,
view2.getHeight());
params.addRule(RelativeLayout.BELOW, view1.getId());
view2.setLayoutParams(params);
}
});
but view2 didn't change its position at all.
i would like to avoid making a new animation for view2 if possible, so
please don't bother to suggest one. ;)
does anyone have some suggestions?
