Why switch button inside viewpager changes state when I hide a view

Question

My code construction is like this:
-->MainActivity

MainActivity
    '-> Fragment  
          '-> WebView  
          '-> Button  
          '-> ViewPager
                '-> ChildFragment  
                      '-> SwitchButton

The button is used to change the visibility of the WebView view. My problem is that when the webView visibility is changed to GONE, the state of the SwitchButton inside the viewPager changes to the default state which is OFF.

您可以使用接口从ChildFragment->适配器进行通信
