java - Move imageview after animation (update position)

I am trying to to do a translate animation on an image view from the bottom to the middle of the screen. Upon finish of the animation, I want the image view to stay there. I dont want the setFillAfter(true) because I want the actual position of the imageview to be updated.

I do it currently by having 2 image view (one at the start of animation and one at the end) and I play with the setVisibility to achieve this. Is this the correct way to do things? Here is the code I used:

<ImageView
    android:id="@+id/ivStart"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:background="@drawable/typer_step_1"
    android:gravity="center"
     />



<ImageView
    android:id="@+id/ivMiddle"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:background="@drawable/typer_step_1"
    android:gravity="center"
    android:visibility="invisible"
     />    








     TranslateAnimation translate = new TranslateAnimation(0, mDestLoc1[0]-mSrcLoc1[0], 0, mDestLoc1[1]-mSrcLoc1[1]);                   
translate.setDuration(2000);
translate.setAnimationListener(new AnimationListener(){

    @Override
    public void onAnimationStart(Animation animation) {}

    @Override
    public void onAnimationEnd(Animation animation) {
        ivMiddle.setVisibility(View.VISIBLE)
                        ivStart.setVisibility(View.INVISIBLE)


    }

    @Override
    public void onAnimationRepeat(Animation animation) {}

});

ivStart.startAnimation(translate);

Then you must set new LayoutParams for your View which is animating. When animation finishes, in your onAnimationEnd part, set new position of your View.

     TranslateAnimation translate = new TranslateAnimation(0, mDestLoc1[0]-mSrcLoc1[0], 0, mDestLoc1[1]-mSrcLoc1[1]);                   
     translate.setDuration(2000);
     translate.setAnimationListener(new AnimationListener(){

         @Override
         public void onAnimationStart(Animation animation) {}

         @Override
         public void onAnimationEnd(Animation animation) {
             RelativeLayout.LayoutParams par = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
             par.topMargin = mDestLoc1[1]-mSrcLoc1[1];
             par.leftMargin = mDestLoc1[0]-mSrcLoc1[0];
             view.setLayoutParams(par);              
         }

         @Override
         public void onAnimationRepeat(Animation animation) {}

     });

     view.startAnimation(translate);
