原理和代码比较简单，就不再多说原理。但使用场景较多，特此记录，代码如下：
public class NoScrollViewPager extends ViewPager {
private boolean noScroll = true;
public NoScrollViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
}
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);
}
//返回false表示不消费事件
@Override
public boolean onTouchEvent(MotionEvent arg0) {
if (noScroll)
return false;
else
return super.onTouchEvent(arg0);
}
//返回false表示不拦截事件
@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) {
//false 表示没有切换动画
super.setCurrentItem(item,false);
}
}
