Swiping left changing color value

[IOException722]

Swiping left or right giving mixed effect of like and dislike even I am swiping right continuously or left continuously.

Even I changed this source code with constrains like if alpha < 0 then dislike else like still it showing some blink(it is because alpha getting zero at some point of time while swiping continuously either side)??

fixed it by Changing these code in swipeListener.java

Instead of // rightView.setAlpha(alpha); // leftView.setAlpha(-alpha);

use below

                Log.e("Abhay","posx "+posX + " "+alpha);
                if(!Float.isNaN(alpha) && alpha<-1.0f)
                    alpha=-0.99f;
                if(!Float.isNaN(alpha) && alpha>1.0f)
                    alpha =0.99f;
                leftView.setAlpha(alpha < 0 ? -alpha : 0);
            rightView.setAlpha(alpha > 0 ? alpha : 0);
