实例如下：
//记录上一次滑动的positionOffsetPixels值
private int lastValue = -1;
private boolean isLeft = true;
mViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
if (positionOffset != 0) {
if (lastValue >= positionOffsetPixels) {
//右滑
isLeft = false;
} else if (lastValue < positionOffsetPixels) {
//左滑
isLeft = true;
}
setIndiactorView(positionOffset,isLeft);
}
lastValue = positionOffsetPixels;
}
@Override
public void onPageSelected(int position) {
if (isLeft){
Log.e("onPageScrolled","--->左划");
}else {
Log.e("onPageScrolled","--->右划");
}
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
