代码例如以下：

try {

Interpolator sInterpolator = new AccelerateInterpolator();

Field mScroller = ViewPager.class.getDeclaredField("mScroller");

mScroller.setAccessible(true);

FixedSpeedScroller scroller = new FixedSpeedScroller(

mViewPager.getContext(), sInterpolator);

mScroller.set(mViewPager, scroller);

} catch (NoSuchFieldException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IllegalArgumentException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IllegalAccessException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

FixedSpeedScroller类的代码：

@SuppressLint("NewApi")

public class FixedSpeedScroller extends Scroller {

private int mDuration = 400;//滑动所用时间

public FixedSpeedScroller(Context context) {

super(context);

}

public FixedSpeedScroller(Context context, Interpolator interpolator) {

super(context, interpolator);

}

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) {

// Ignore received duration, use fixed one instead

super.startScroll(startX, startY, dx, dy, mDuration);

}

@Override

public void startScroll(int startX, int startY, int dx, int dy) {

// Ignore received duration, use fixed one instead

super.startScroll(startX, startY, dx, dy, mDuration);

}

}
