特别是在定义了 PageTransformer 来实现Page之间的切换动画
会调用到ViewPaper#setScrollState() -> 然后再调用 ViewPager#enableLayers()
默认就开启了硬件加速,因此在动画执行过程中，会预先执行硬件加速,可能就导致了View动画执行的时候掉帧
可以开启 Show HardWare layers updates 来锁定开启硬件加速的View

//以下是解决办法
@Override
public void onPageScrollStateChanged(int scrollState) {
    // A small hack to remove the HW layer that the viewpager add to each page when scrolling.
    if (scrollState != ViewPager.SCROLL_STATE_IDLE) {

硬件加速分四个等级
Application Level:<application android:hardwareAccelerated="true" ...>
Activity Level:<application android:hardwareAccelerated="true">
          <activity ... />
          <activity android:hardwareAccelerated="false" />
         </application>
即使在Application层开启了硬件加速,也可以对单个的Activity选择是否开启硬件加速
Window Level: getWindow().setFlags(
                              WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED,
                              WindowManager.LayoutParams.FLAG_HARDWARE_ACCELERATED);
