[android-developers] Re: Animation fillAfter(true) and click locations

Hey Mark thanks for the insight. I did indeed try to move the control
but I am getting a class cast issue (can't for the life of me work out
why) so I kinda gave up on that root. My layout am animating can you
shed any light? I am using the following chunks.

public void onAnimationEnd(Animation animation)
{
if(arrowUP){
arrow.setBackgroundResource(R.drawable.arrowdown);
arrowUP = false;
Display display = ((WindowManager)
getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
mapHolder.setLayoutParams(new
LinearLayout.LayoutParams(0,arrow.getHeight()-display.getHeight()));

}else{
arrow.setBackgroundResource(R.drawable.arrowup);
arrowUP = true;
}

mapHolder.requestLayout();
arrow.requestLayout();

}

and the xml for that control looks like this

<LinearLayout android:orientation="vertical" android:gravity="top|
center_horizontal" android:layout_gravity="left" android:id="@+id/
maplayout" android:layout_width="wrap_content"
android:layout_height="fill_parent">
<Button android:text="" android:background="@drawable/arrowup"
android:layout_marginRight="5dip" android:layout_marginBottom="5dip"
android:layout_marginLeft="5dip" android:layout_marginTop="20dip"
android:id="@+id/Button01" android:layout_width="wrap_content"
android:layout_height="wrap_content"></Button>
<Button android:text="" android:background="@drawable/arrowup"
android:layout_margin="5dip" android:id="@+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></Button>
<Button android:text="" android:background="@drawable/arrowup"
android:layout_margin="5dip" android:id="@+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></Button>
<Button android:text="" android:background="@drawable/arrowup"
android:layout_margin="5dip" android:id="@+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></Button>
<Button android:text="" android:background="@drawable/arrowup"
android:layout_margin="5dip" android:id="@+id/ButtonArrow"
android:layout_width="wrap_content"
android:layout_height="wrap_content"></Button>
</LinearLayout>

The error I get is a classcast exception on trying to setLayoutParam.
