android - 两个实时互相监听的EditText怎么设置只能输入到小数点后四位？

Question

这是第一个edittext的et1的监听事件，加了第二个edittext的et2的设置文本事件后就出现混乱，同理在第二个edittext的et2的监听事件也遇到了此问题。求解答。

Answer 1

The listening event of edittext's et1 is added with the setting text of the second edittext's et2. There is no error in this logic. I have also written it this way. It will not go wrong when I write it this way. Maybe you have written it wrong in other places

Answer 2

TextView#setFilters()
