import android.view.View;
import android.view.View.OnTouchListener;
import android.widget.Button;
import android.widget.LinearLayout.LayoutParams;
import android.widget.RelativeLayout;

public class MainActivity extends Activity {
int windowwidth;
int screenCenter;
int x_cord, y_cord;
int Likes = 0;
RelativeLayout parentView;
float alphaValue = 0;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mainlayout);
    parentView = (RelativeLayout) findViewById(R.id.layoutview);
    windowwidth = getWindowManager().getDefaultDisplay().getWidth();
    screenCenter = windowwidth / 2;
    int[] myImageList = new int[] { R.drawable.event1, R.drawable.event2,
            R.drawable.event3, …
