Simulate 3D Hologram effect

Last post show a DIY 3D Hologram Projector for smartphone to view 3D Hologram Video in YouTube. Here I try to simulate the effect in Android App.

MainActivity.java

package com.blogspot.android_er.androidmirror;

import android.animation.ObjectAnimator;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.ImageView;

public class MainActivity extends AppCompatActivity {

    ImageView image2, image4, image6, image8;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        image2 = (ImageView)findViewById(R.id.image2);
        image4 = (ImageView)findViewById(R.id.image4);
        image6 = (ImageView)findViewById(R.id.image6);
        image8 = (ImageView)findViewById(R.id.image8);

        image2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                flipX();
            }
        });

        image4.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                flipY();
            }
        });

        image6.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                flipY();
            }
        });

        image8.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                flipX();
            }
        });
    }

    private void flipX(){
        ObjectAnimator flip2 = ObjectAnimator.ofFloat(image2, "rotationX", 0f, 360f);
        ObjectAnimator flip4 = ObjectAnimator.ofFloat(image6, "rotationY", 0f, 360f);
        ObjectAnimator flip6 = ObjectAnimator.ofFloat(image4, "rotationY", 0f, -360f);
        ObjectAnimator flip8 = ObjectAnimator.ofFloat(image8, "rotationX", 0f, -360f);
        flip2.setDuration(3000);
        flip4.setDuration(3000);
        flip6.setDuration(3000);
        flip8.setDuration(3000);
        flip2.start();
        flip4.start();
        flip6.start();
        flip8.start();
    }


    private void flipY(){
        ObjectAnimator flip2 = ObjectAnimator.ofFloat(image2, "rotationY", 0f, 360f);
        ObjectAnimator flip4 = ObjectAnimator.ofFloat(image6, "rotationX", 0f, 360f);
        ObjectAnimator flip6 = ObjectAnimator.ofFloat(image4, "rotationX", 0f, -360f);
        ObjectAnimator flip8 = ObjectAnimator.ofFloat(image8, "rotationY", 0f, -360f);
        flip2.setDuration(3000);
        flip4.setDuration(3000);
        flip6.setDuration(3000);
        flip8.setDuration(3000);
        flip2.start();
        flip4.start();
        flip6.start();
        flip8.start();
    }
}

Where "@drawable/androider" is a 100x100 PNG with alpha channel.
