Question

I am creating a custom toggle switch i all most done with the design and the functionality but there is one thing blocking me, I tried to add animation on toggle to the thumb basically a button the animation towards right works perfect but the issue is with the animation towards left here is the code I am using to play both animations.

    private void playToggleanimation()
    {
        if(toggleAnimation != null && !toggleAnimation.hasEnded())
        {
            toggleAnimation.setAnimationListener(null);
            toggleAnimation.cancel();
        }
        View v = findViewById(button);
        toggleAnimation = (checked) ? new TranslateAnimation(v.getLeft(), getMeasuredWidth() / 2, 0, 0) : new TranslateAnimation(v.getLeft(), 0, 0, 0);
        toggleAnimation.setAnimationListener(listener);
        toggleAnimation.setFillAfter(true);
        toggleAnimation.setFillEnabled(true);
        toggleAnimation.setDuration(250);
        v.clearAnimation();
        v.startAnimation(toggleAnimation);
    }

Thanks for any help.

I figured it out the issue was with the getLeft() method, instead of using this line

toggleAnimation = (checked) ? new TranslateAnimation(v.getLeft(), getMeasuredWidth() / 2, 0, 0) : new TranslateAnimation(v.getLeft(), 0, 0, 0);

I used below line of code to create animation, it worked fine.

toggleAnimation = (checked) ? new TranslateAnimation(v.getLeft(), getMeasuredWidth() / 2, 0, 0) : new TranslateAnimation(getMeasuredWidth() / 2, 0, 0, 0);

The getLeft() method was always returning 0.
