java.lang.IllegalArgumentException: pointerIndex out of range

在使用ViewPager展示图片的时候，使用了PhotoView对ImageView进行多点触控放大缩小，出现了java.lang.IllegalArgumentException: pointerIndex out of range

解决方法如下

public class ViewPagerFixed extends android.support.v4.view.ViewPager {  

    public ViewPagerFixed(Context context) {  
        super(context);  
    }  

    public ViewPagerFixed(Context context, AttributeSet attrs) {  
        super(context, attrs);  
    }  

    @Override  
    public boolean onTouchEvent(MotionEvent ev) {  
        try {  
            return super.onTouchEvent(ev);  
        } catch (IllegalArgumentException ex) {  
            ex.printStackTrace();  
        }  
        return false;  
    }  

    @Override  
    public boolean onInterceptTouchEvent(MotionEvent ev) {  
        try {  
            return super.onInterceptTouchEvent(ev);  
        } catch (IllegalArgumentException ex) {  
            ex.printStackTrace();  
        }  
        return false;  
    }  
}
