ObjectAnimator.ofInt() is not making any changes

Hi,

I am using the layout below to make a small test regarding the ObjectAnimator,

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" > <LinearLayout android:id="@+id/panel" android:layout_width="match_parent" android:layout_height="300dp" android:background="@android:color/black" android:orientation="vertical" > <TextView android:id="@+id/text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Hello World" android:textColor="@android:color/white" android:textSize="25sp" /> </LinearLayout> </RelativeLayout>

in the main activity i wrote the following,

LinearLayout mPanel;

mPanel = (LinearLayout) findViewById(R.id.panel);

ObjectAnimator.ofInt(mPanel, "bottom", mPanel.getTop(), mPanel.getBottom()).start();

but nothing is showing, and the linearLayout disappeared
