取消Fragment切換時間，Fragment+ViewPager靜止滑動，去掉默認的滑動效果

public class NoScrollViewPager extends ViewPager {
    private boolean noScroll = true; //true 表明不能滑動 //false 表明能滑動
//主佈局：用viewpager點noScroll而後，記得複製這個佈局的路徑而後粘貼到佈局裏的viewpager，把實例化的名字改成NoScrollViewPager該類的名字。
 
    public NoScrollViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }
 
    public NoScrollViewPager(Context context) {
        super(context);
    }
 
    public void setNoScroll(boolean noScroll) {
        this.noScroll = noScroll;
    }
 
    @Override
    public void scrollTo(int x, int y) {
        super.scrollTo(x, y);
    }
 
    @Override
    public boolean onTouchEvent(MotionEvent arg0) {
        /* return false;//super.onTouchEvent(arg0); */
        if (noScroll)
            return false;
        else
            return super.onTouchEvent(arg0);
    }
 
    @Override
    public boolean onInterceptTouchEvent(MotionEvent arg0) {
        if (noScroll)
            return false;
        else
            return super.onInterceptTouchEvent(arg0);
    }
 
    @Override
    public void setCurrentItem(int item, boolean smoothScroll) {
        super.setCurrentItem(item, smoothScroll);
    }
 
    @Override
    public void setCurrentItem(int item) {
        super.setCurrentItem(item, false);//表示切換的時候，不須要切換時間。
    }
 
}
