解決PhotoView縮放越界的問題

PhotoView是一个老牌的图片缩放框架但是在和ViewPager配合使用的时候,由于多点触控,容易导致越界异常,使APP崩溃!(crashVersion 4.4.4)

百度了一下解决方案很多,我这边的解决方法是定义一个类继承vewpager重写dispatchTouchEvent方法,将异常捕获

@Override  
    public boolean dispatchTouchEvent(MotionEvent ev) {  
           try {  
                  return super .dispatchTouchEvent(ev);  
          } catch (IllegalArgumentException ignored) {  
          } catch (ArrayIndexOutOfBoundsException e) {  
          }  

           return false ;  

   }

下面贴出异常
