EditText长度超过限制后如何停止输入 [英] How to stop taking input after EditText length crosses a limit

问题描述

我知道已经问了几个问题，但是我有一些不同的查询.

I know there are a couple of questions already been asked, but I have a little different query.

我们如何限制在EditText中输入的最大字符数?我是否这样做

How do we put a limit on the maximum number of characters to be inputted in EditText? Whether I do this

android:maxLength="7"

或这个

((EditText)findViewById(R.id.zip)).setFilters(new InputFilter[] {
    new InputFilter.LengthFilter(7)
});

我仍然可以在文本字段中输入内容，尽管它是不可见的，也没有考虑在内.如果我继续输入，则输入将在限制之后变得不可见，但是test-suggestions会继续为更大数量的字母而构建.

I can still type into the text field, though it's not visible and not taken into account. If I keep typing, the input becomes invisible after the limit, but the test-suggestions keep building for higher number of letters.

假设我的限制是7个，我输入了10个字母，那么我只会看到前7个字母，但是文本建议将显示10个字母的单词.此外，我需要按3次退格键才能真正开始从显示的7个字母的单词中删除字母.

Suppose my limit is 7 and I typed 10 letters, then I would only see the first 7 letters, but text-suggestions will show 10 letter words. Furthermore, I need to press backspace 3 times to actually start deleting letters from my shown 7-letter word.

所以，我的问题是:有没有办法在一定的字符长度后停止接受输入?

So, my question is: Is there a way to stop taking input after a certain character length?

PS :不用说，尽管我不希望在7个字母之后输入内容，但我允许删除或退格.

PS: Needless to say, but though I don't want input to be inputted after 7 letters, I would allow delete or backspace.

Just add this to your EditText. It will definitely work.
