    <p>i have 2 views in a <code>RelativeLayout</code> like this:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" &gt; &lt;View android:id="@+id/view1" android:layout_width="match_parent" android:layout_height="200dp" android:background="@drawable/shape_red"/&gt; &lt;View android:id="@+id/view2" android:layout_width="match_parent" android:layout_height="50dp" android:layout_below="@id/view1" android:background="@drawable/shape_blue"/&gt; &lt;/RelativeLayout&gt; </code></pre> <p>now, i animate the y property of <code>view1</code> from 0 to 300. but i want <code>view2</code> to change its position according to <code>view1</code> - because <code>view2</code> is set to be below (layout-below) <code>view1</code>.</p> <p>as this isn't working, i tried to add an <code>onAnimationEnd</code> listener to the animation. like this:</p> <pre><code> 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); } }); </code></pre> <p>but <code>view2</code> didn't change its position at all.</p> <p>i would like to avoid making a new animation for <code>view2</code> if possible, so please don't bother to suggest one. ;)</p> <p>does anyone have some suggestions?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
