public class FixedSpeedScroller extends Scroller { private int mDuration = 1500; public FixedSpeedScroller(Context context) { super(context); } public FixedSpeedScroller(Context context, Interpolator interpolator) { super(context, interpolator); } @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); } public void setmDuration(int time) { mDuration = time; } public int getmDuration() { return mDuration; } }
使用
try { Field field = ViewPager.class.getDeclaredField("mScroller"); field.setAccessible(true); FixedSpeedScroller scroller = new FixedSpeedScroller(mViewPager.getContext(), new AccelerateInterpolator()); field.set(mViewPager, scroller); scroller.setmDuration(2000); } catch (Exception e) { LogUtils.e(TAG, "", e); }
