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、通过反射修改viewpage 的scoller<pre name="code" class="java">try {
//通过反射找到当前class 文件里的mScroller的mScrooller对象 //getDeclaredField是可以获取一个类的所有字段. //getField只能获取类的public 字段. Field mField = ViewPager.class.getDeclaredField("mScroller");
mField.setAccessible(true);
//设置了private属性的对象也能获取的 Scroller mScroller = new ViewPageFixedSpeedScroller(page.getContext(), new LinearInterpolator());
mField.set(page, mScroller);
}
catch (Exception e) {
e.printStackTrace();
}
