获取的EditText的字符数 [英] Getting character count of EditText

问题描述

我试图让一个EditText的字符数。我看了成的EditText TextView的和阶级的不同属性，但似乎没有要返回字符的数量的函数。我曾尝试使用TextWatcher，但因为有时我从preferences载入保存的消息进入的EditText和TextWatcher不计字没有输入正确的话就是不理想。

I'm trying to get a character count of an EditText. I've looked into different properties of the EditText and TextView classes, but there doesn't seem to be a function that returns the amount of characters. I have tried to use the TextWatcher, but that is not ideal since sometimes I load a saved message into the EditText from the preferences, and TextWatcher does not count characters not typed right then.

任何帮助将是巨大的！

Any help would be great!

干杯！

推荐答案

只要抓住了的EditText文本作为一个字符串，并检查它的长度：

Just grab the text in the EditText as a string and check its length:

int length = editText.getText().length();
