public class ViewPageFixedSpeedScroller extends Scroller { 
  private int mDuration = 300; 
  public ViewPageFixedSpeedScroller(Context context) { 
    super(context); 
    // TODO Auto-generated constructor stub 
  } 
  public ViewPageFixedSpeedScroller(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; 
  } 
} 

2、通過反射修改viewpage 的scoller<pre name="code" class="java">try { 
//通過反射找到當(dāng)前class 文件里的mScroller的mScrooller對(duì)象 
//getDeclaredField是可以獲取一個(gè)類的所有字段.  
//getField只能獲取類的public 字段.  
  Field mField = ViewPager.class.getDeclaredField("mScroller");  mField.setAccessible(true);//設(shè)置了private屬性的對(duì)象也能獲取的 
  Scroller mScroller = new ViewPageFixedSpeedScroller(page.getContext(), new LinearInterpolator()); 
  mField.set(page, mScroller); 
} catch (Exception e) { 
  e.printStackTrace(); 
}
