我的edittext片段cursor在fragment layout开始时visible不可见。当您开始输入任何内容时，即cursor成为visible，cursor变为visible。我只要触摸/点击edittext，就希望onFocusChangeListener成为visible。我尝试了Fragment，但它只在layout上启用了游标framelayout。另外，我想在layout触摸/点击时显示不同的edittext（仅更改<?xml version="1.0" encoding="utf-8"?>

）。有没有办法在没有片段交易的情况下实现这个目标？

我在xml中的edittext中添加了android:focusableInTouchMode="false"，并使用了setOnClickListener而不是TextWatcher。
