You'll need to create a RelativeLayout.LayoutParams for your ImageView with a CENTER_IN_PARENT rule, then apply it with setLayoutParams(ViewGroup.LayoutParams params).

Here's an example:

    ImageView imageView = (ImageView)findViewById(R.id.iv_image);
    RelativeLayout.LayoutParams layoutParams = (RelativeLayout.LayoutParams)imageView.getLayoutParams();
    layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
    imageView.setLayoutParams(layoutParams);

 <ImageView 
                        android:id="@+id/photo2"
                        android:src="@drawable/loglog"
                        android:layout_width="50dp"
                        android:layout_height="50dp"
                        android:gravity="center"
                        android:layout_gravity="center"
 />

For moving the view, add this code

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
RelativeLayout partieoption = (RelativeLayout) findViewById(R.id.partieoption);
      ImageView iv = (ImageView) findViewById(R.id.photo2);
ObjectAnimator transAnimation= ObjectAnimator.ofFloat(iv, x, iv.getX(), width/2);
  transAnimation.setDuration(3000);
  transAnimation.start();

use the gravity attribute in your xml, like this:

android:layout_gravity="center"

in your case, i think will be like this:

<RelativeLayout
android:id="@+id/partieoption"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:weightSum="6"
android:orientation="horizontal" >

<ImageView 
   android:id="@+id/photo2"
   android:src="@drawable/loglog"
   android:layout_width="50dp"
   android:layout_height="50dp"
   android:layout_gravity="center"
/>
</RelativeLayout>
