I have an imageview with a default image already set from the xml, and I want to change it's image pragmatically so that the new image will scale to the previous image size, both of the images are rounded.

I have tried setting the scaleType attribute to different values before setting the new image but it didn't work.

This is the xml:

<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" >


<ImageView
    android:id="@+id/up_right_circle_firstiv"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:scaleType="fitXY"
    android:src="@drawable/circle_medium_up" />

This is the activity code:

public class MainActivity extends Activity {
ImageView middleCircle;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    middleCircle = (ImageView) findViewById(R.id.up_right_circle_firstiv);
    middleCircle.setImageResource(R.drawable.round_pic_one);
}

}

Inside the activity.

I have uploaded the screenshots:
