知道编辑文本何时完成编辑

问题描述

我如何知道我的编辑文本何时完成编辑?就像用户选择下一个框，或者按下软键盘上的完成按钮时一样.

How do I know when my edit text is done being edited? Like when the user selects the next box, or presses the done button on the soft keyboard.

我想知道这一点，以便我可以钳位输入.看起来文本观察者的 afterTextChanged 发生在输入每个字符之后.我需要对输入进行一些计算，所以我想避免在输入每个字符后进行计算.

I want to know this so I can clamp the input. It looks like text watcher's afterTextChanged happens after each character is entered. I need to do some calculations with the input, so I would like to avoid doing the calculation after each character is entered.

谢谢

推荐答案

通过使用类似这样的东西

By using something like this

 meditText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            switch (actionId){
                case EditorInfo.IME_ACTION_DONE:
                case EditorInfo.IME_ACTION_NEXT:
                case EditorInfo.IME_ACTION_PREVIOUS:
                    yourcalc();
                    return true;
            }
            return false;
        }
    });
