Transform effect

Transform effect is the effect when slider changes.

There are 15 kind of preset transform effect you can use via call setPresetTransformer(Transformer ts).

If you want to custom your own transform effect:

###Step1:

Create a class which extends from BaseTransformer

for example:

public class AccordionTransformer extends BaseTransformer {

}

###Step2:

Before you do override, you have to know how ViewPager transformer works. If you are not familiar with it, please read this.

Override onTransform(View view,float position) method.

@Override
protected void onTransform(View view, float position) {
  ViewHelper.setPivotX(view,position < 0 ? 0 : view.getWidth());
  ViewHelper.setScaleX(view,position < 0 ? 1f + position : 1f - position);
}

NOTICE: Please use ViewHelp (thanks to NineOldDroid) to make it compatible with Android 2.2+. ###Step3

Use it.

slider.setPagerTransformer(false,new AccordionTransformer());
