设置ViewPager不可以滑动翻页public class NoScrollViewPager extends ViewPager {public NoScrollViewPager(Context context) {super(context);}public NoScrollViewPager(Context context, AttributeSet attrs) {super(context, attrs);}@Overridepublic boolean onInterceptTouchEvent(MotionEvent ev){return false;}@Overridepublic boolean onTouchEvent(MotionEvent ev){return false;}}

修改ViewPager调用setCurrentItem时，滑屏的速度     1、自定义一个Scroll类，用于控制ViewPager滑动速度  import android.content.Context;import android.support.v4.view.ViewPager;import android.view.animation.Interpolator;import android.widget.Scroller;import java.lang.reflect.Field;public class FixedSpeedScroller extends Scroller {      private int mDuration = 0;// 滑动速度        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) {          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);      }        /**      * 设置速度      * @param duration      */      public void setScrollDuration(int duration){          this.mDuration = duration;      }        public void initViewPagerScroll(ViewPager viewPager) { //(NoScrollViewPager viewPager)          try {              Field mScroller = ViewPager.class.getDeclaredField("mScroller");              mScroller.setAccessible(true);              mScroller.set(viewPager, this);          } catch(Exception e) {              e.printStackTrace();          }      }  }      2、在Activity中设置切换速度  FixedSpeedScroller scroller = new FixedSpeedScroller(mContext);  scroller.setScrollDuration(0);  scroller.initViewPagerScroll(am_viewpager);  //am_viewpager为你的viewpager
