设置ViewPager滑动切换速度

一、自定义一个Scroll类，用于控制ViewPager滑动速度：

public class FixedSpeedScroller extends Scroller {
		private int mDuration = 1000;

		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) {
			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 void setmDuration(int time) {
			mDuration = time;
		}

		public int getmDuration() {
			return mDuration;
		}
	}

二.初始化ViewPager

        /**
	 * 设置ViewPager切换速度
	 */
	private void setViewPagerScrollSpeed() {
		try {
			Field mScroller = null;
			mScroller = ViewPager.class.getDeclaredField("mScroller");
			mScroller.setAccessible(true);
			FixedSpeedScroller scroller = new FixedSpeedScroller(mViewPager.getContext());
			mScroller.set(mViewPager, scroller);
		} catch (NoSuchFieldException e) {

		} catch (IllegalArgumentException e) {

		} catch (IllegalAccessException e) {

		}
	}
