HOW TO USE

Set Animation for every single view

• By calling View.setTag() to set params of the animations

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    View imageView3 = view.findViewById(R.id.imageView3);
    imageView3.setTag(ChildsTranslateTransformer.KEY_OFFSET_X_FACTOR, 2f);
    imageView3.setTag(ChildsTranslateTransformer.KEY_IS_REVERSE, true);
    imageView3.setTag(ChildsTranslateTransformer.KEY_MARGIN_WHEN_REVERSE, -30f);

    View line = view.findViewById(R.id.line);
    line.setTag(ChildsTranslateTransformer.KEY_OFFSET_X_FACTOR, 2f);
    line.setTag(ChildsTranslateTransformer.KEY_IS_REVERSE, true);
    line.setTag(ChildsTranslateTransformer.KEY_MARGIN_WHEN_REVERSE, -70f);

    View ll_top = view.findViewById(R.id.ll_top);
    ll_top.setTag(ChildsTranslateTransformer.KEY_OFFSET_X_FACTOR, 2f);
    ll_top.setTag(ChildsRotateTransformer.KEY_ROTATE, -90f);
    ll_top.setTag(ChildsRotateTransformer.KEY_ROTATE_PIVOTX_RATIO, 1f);
    ll_top.setTag(ChildsRotateTransformer.KEY_ROTATE_PIVOTY_RATIO, 0.5f);

    View textView1 = view.findViewById(R.id.textView1);
    textView1.setTag(ChildsTranslateTransformer.KEY_OFFSET_X_FACTOR, 3f);

    View imageView1 = view.findViewById(R.id.imageView1);
    imageView1.setTag(ChildsTranslateTransformer.KEY_OFFSET_X_FACTOR, 2f);
    imageView1.setTag(ChildsRotateTransformer.KEY_ROTATE, 90f);
    imageView1.setTag(ChildsRotateTransformer.KEY_ROTATE_PIVOTX_RATIO, 1f);
    imageView1.setTag(ChildsRotateTransformer.KEY_ROTATE_PIVOTY_RATIO, 0.5f);
}

Set Animation for the page view(ViewGroup)

• The same, by calling View.setTag() to set params of the animations

Set Complex Animation for the page view(ViewGroup)

• choose one or more Transformers to add into the complex one

ComplexChildsTransformer complexChildsTransformer = new ComplexChildsTransformer();
complexChildsTransformer.addTransformer(new ChildsTranslateTransformer());
complexChildsTransformer.addTransformer(new ChildsRotateTransformer());
complexChildsTransformer.addTransformer(new ChildsAlphaTransformer());
complexChildsTransformer.addTransformer(new ChildsScaleTransformer());
//choose one or more Transformers to add into the complex one
//complexChildsTransformer.addTransformer(new PageDefaultTransformer());//普通vp滑动
//complexChildsTransformer.addTransformer(new PageAlphaTransFormer(false/*可修改*/, true/*可修改*/));//透明度
//complexChildsTransformer.addTransformer(new PageCubeInnerTransformer(/*可传参数*/));//立方体内部
//complexChildsTransformer.addTransformer(new PageCubeOuterTransformer());//立方体外部
//complexChildsTransformer.addTransformer(new PageDepthTransformer(/*可传参数*/));//深度变化
//complexChildsTransformer.addTransformer(new PageExtrudingTransformer());//挤压
complexChildsTransformer.addTransformer(new PageFlipTransformer(/*可传参数*/));//flip
//complexChildsTransformer.addTransformer(new PageInRightUpTransformer());//右上到左下
//complexChildsTransformer.addTransformer(new PageInRightDownTransformer());//右下到左上
//complexChildsTransformer.addTransformer(new PageRotateTransformer(/*可传参数*/));//旋转
//complexChildsTransformer.addTransformer(new PageZoomOutTransformer(/*可传参数*/));//Zoom out
vp.setPageTransformer(true, complexChildsTransformer);
