最近做项目要求某种情况下ViewPager不能滑动，那么我们只需要重写这个方法就可以禁止ViewPager滑动

IndexViewPager.java:

import android.content.Context;import android.support.v4.view.ViewPager;import android.util.AttributeSet;import android.view.MotionEvent;public class IndexViewPager extends ViewPager {	private boolean isCanScroll = false;	public IndexViewPager(Context context) {		super(context);	}	public IndexViewPager(Context context, AttributeSet attrs) {		super(context, attrs);	}	public void setScanScroll(boolean isCanScroll) {		this.isCanScroll = isCanScroll;	}	@Override	public void scrollTo(int x, int y) {		super.scrollTo(x, y);	}	@Override	public boolean onTouchEvent(MotionEvent arg0) {		// TODO Auto-generated method stub		if (isCanScroll) {			return super.onTouchEvent(arg0);		} else {			return false;		}	}	@Override	public void setCurrentItem(int item, boolean smoothScroll) {		// TODO Auto-generated method stub		super.setCurrentItem(item, smoothScroll);	}	@Override	public void setCurrentItem(int item) {		// TODO Auto-generated method stub		super.setCurrentItem(item);	}	@Override	public boolean onInterceptTouchEvent(MotionEvent arg0) {		// TODO Auto-generated method stub		if (isCanScroll) {			return super.onInterceptTouchEvent(arg0);		} else {			return false;		}	}}
