Better way to Format Currency Input editText?
With this u can format the incoming String before its display, so u can easily append a "" and other stuff
有了这个，你可以在显示之前格式化传入的字符串，所以你可以轻松地附加一个“”和其他东西

You can achieve that by using a TextWatcher. Look at this Questionwhich is quite similar to yours.
您可以通过使用TextWatcher来实现这一点。看看这个问题，它和你的非常相似。
