如何控制viewpager的滑动

Answer 1

方法很简单，使用Java的反射机制，获取到ViewPager的Scoller对象，换成我们自定义的就可以了。public class FixedSpeedScroller extends Scroller {
private int mDuration;//滑动的速度，0为最快
public FixedSpeedScroller(Context context) {
super(context);
}
public FixedSpeedScroller(Context context, Interpolator interpolator) {
super(context, interpolator);
}
@SuppressLint("NewApi")
public FixedSpeedScroller(Context context, Interpolator interpolator,
boolean flywheel) {
super(context, interpolator, flywheel);
}
@Override
public void startScroll(int startX, int startY, int dx, int dy, int duration) {
super.startScroll(startX, startY, dx, dy, mDuration);
}
@Override
public void startScroll(int startX, int startY, int dx, int dy) {
super.startScroll(startX, startY, dx, dy, mDuration);
}
public int getmDuration() {
return mDuration;
}
public void setmDuration(int mDuration) {
this.mDuration = mDuration;
}
try {
Field mScroller;
mScroller = ViewPager.class.getDeclaredField("mScroller");
mScroller.setAccessible(true);
FixedSpeedScroller scroller = new FixedSpeedScroller(
pager.getContext());
scroller.setmDuration(0);//设置滑动的速度
mScroller.set(pager, scroller);
} catch (NoSuchFieldException e) {
} catch (IllegalArgumentException e) {
} catch (IllegalAccessException e) {
}

Answer 2

viewpager有个监听器，应该可以做到你所需要的需求。
