20 | } 21 | ``` 22 | * 参数position 23 | 给定界面的位置相对于屏幕中心的偏移量。在用户滑动界面的时候，是动态变化的。那么我们可以将position的值应用于setAlpha(), setTranslationX(), or setScaleY()方法，从而实现自定义的动画效果。 24 | 另 外在ViewPager滑动时，内存中存活的Page都会执行transformPage方法，在滑动过程中涉及到两个Page，当前页和下一页，而它们 的position值是相反的（因为是相对运动,一个滑入一个滑出），比如，页面A向右滑动到屏幕一半，页面B也正好处于一半的位置，那么A和B的 position为：0.5 和 -0.5 25 | position == 0 ：当前界面位于屏幕中心的时候 26 | position == 1 ：当前Page刚好滑出屏幕右侧 27 | position == -1 ：当前Page刚好滑出屏幕左侧 28 | 29 | -------------------------------------------------------------------------------- /app/src/main/java/com/youmu/scrollpager/MainActivity.java: -------------------------------------------------------------------------------- 1 | package com.youmu.scrollpager;
