    copied!<p>This should be the simplest thing. I'm trying to use a ViewPropertyAnimator to scale an ImageView around its center. </p> <p>I've got the following layout:</p> <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" &gt; &lt;ImageView android:id="@+id/imageView" android:background="@android:color/black" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_centerHorizontal="true" android:layout_centerVertical="true"/&gt; &lt;ImageView android:id="@+id/target" android:layout_centerInParent="true" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/crosshair" /&gt; </code></pre> <p></p> <p>Then I have the following code:</p> <pre><code>// Now we show the burst view if(mLastBurst != null) { ((FrameLayout)(mLastBurst.getParent())).removeView(mLastBurst); mLastBurst.animate().cancel(); mLastBurst.setVisibility(View.GONE); } mLastBurst = getLayoutInflater().inflate(R.layout.target, null); mLastBurst.setX(event.getX()-mLastBurst.getWidth()/2); mLastBurst.setY(event.getY()-mLastBurst.getHeight()/2); mLastBurst.setPivotX(50); mLastBurst.setPivotY(50); mLastBurst.animate().scaleXBy(10).scaleYBy(10).setDuration(500); addContentView(mLastBurst,new ViewGroup.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); </code></pre> <p>When I run the code all that happens is that rather than scaling the image around the center of the image, the image drifts over to the left.</p> <p>I've played with the pivotX and pivotY values to no avail. This should be simple and I guess I'm missing something obvious.</p>
