所以我把它设置为当相应的EditText框处于焦点时显示字符计数。并且当用户单击其他地方时不可见。但是当我进入不同的页面，然后回到上一页时，所有的字符计数字段都会弹出，但是一旦你点击每个单独的字段，它就会恢复功能。所以我希望那些字符字段保持非从其他页面返回到该页面时可见。
下面是控制字符计数TextView的代码。

澄清：我希望在返回到包含字符计数的片段时使字符计数TextView不可见。例如，我正在填写一个包含字符计数的表单，我转到另一个片段，然后返回到包含该表单的片段，此时字符计数可见。我希望在返回到该片段时使字符计数TextView不可见。

• 当用户返回到该片段时使字符计数不可见。

任何建议都很感谢。谢谢。
