TextWatcher事件被解雇多次 [英] TextWatcher events are being fired multiple times

问题描述

我有一个恼人的问题与TextWatcher。我一直在寻找的网站，但无法找到任何东西。 AP preciate如果有人可以帮助我。

I have an annoying problem with TextWatcher. i've been searching the web but couldnt find anything. appreciate if someone could assist me.

出于某种原因，调用TextWatcher事件的在一个文本的变化的是飘忽不定。有时它们被触发一次（如他们应该是），有时两次，有时3次。不知道为什么，整个事情是非常简单的。有时也对afterTextChanged（）可编辑的参数返回的toString）长（）为空值（和

For some reason the calls to the TextWatcher events upon one text change are erratic. sometimes they are being triggered once (like they should be), sometimes twice, and sometimes 3 times. have no idea why, the whole thing is very straight forward. also sometimes the Editable parameter on afterTextChanged() returns empty values in toString() and length().

code是如下：

    private TextWatcher mSearchAddressTextChangeListener = new TextWatcher() {
        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) { }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) { }

        @Override
        public void afterTextChanged(Editable searchedAddress) {
           System.out.println("called multiple times.");   
        }
    };

在 afterTextChanged（）（和的AsyncTask ）即时没有进行任何更改文本或的EditText 视图。

inside afterTextChanged() (and the AsyncTask) im not making any change to the text or the EditText view.

我看到问事件被调用两次的，但具有事件即时触发更多（或更少）的两倍。

i saw the question asked in Events of textwatcher are called twice, but im having the events triggered more (or less) than twice.

反正，AP preciate任何帮助。

anyway, appreciate any help.

编辑：我删除afterTextChanged的内容（）导致此问题的发生，甚至没有我的code。是什么使我相信这是一个错误。当一个空间字符输入一个普通字符之后（事件处理程序被触发两次），或在一个普通字符被删除后，空间字符（退格键，事件处理程序被触发3次）的错误是存在的。帮助仍将AP preciated。

I removed the content of afterTextChanged() cause this problem is happening even without my code. what leads me to believe this is a bug. The bug is occuring when a 'space' char is entered right after a regular char (event handlers are triggered twice) or when a 'space' char after a regular char is removed (backspace. event handlers are triggered 3 times). help will still be appreciated.

推荐答案

我有同样的问题，当我pressed退格键光标在一个连续的文本年底，afterTextChange被称为3次： - 第一次用正确的价值 - 第二次有明确的价值 - 第三次为正确的值再次

I had the same kind of problem, when I pressed backspace with cursor at the end of a continuous text, afterTextChange was called 3 times: - The first time with the correct s value - The second time with a clear value - The third time with the correct value again

在其搜索了很多在网络上，我试图改变我的EditText inputType到

After having search a lot on the web, I tried to change my EditText inputType to

android:inputType="textNoSuggestions"

不要问我为什么，但它的工作，afterTextChanged现在被称为一次。

Don't ask me why, but it worked, afterTextChanged is now called only once.
