Android的多的EditText无法实现监听器 [英] Android Multiple EditText can't implement listener

问题描述

我有了解如何控制我的听众散装的几个问题。我已经成功地得到堆栈溢出，但EditText上一些工作是推动我nutts。

hi I'm having a few problems understanding how to control my listeners in bulk. I've managed to get a few working from Stack Overflow but EditText is driving me nutts.

我有3个editTexts，他们都愉快地工作，如果我idenpentatly输入code，但我想他们包裹起来都成一个方法用一个开关情况。

I have 3 editTexts and they all work happily if I idenpentatly enter the code, but I want to wrap them all up into one method with a switch case.

在此刻我的code一EditText上看起来像这样（和两个它有点乱）

at the moment my code for one edittext looks like so (and with two more its a bit messy)

intTextValue = (EditText)findViewById(R.id.intervalValue);
      intTextValue.addTextChangedListener(new TextWatcher() {

            @Override
            public void afterTextChanged(Editable s) {
                // TODO Auto-generated method stub
Double.parseDouble(intTextValue.getText().toString());

                if (textViewTouchIsHuman == true) {
                    intSeekValue = Double.parseDouble(intTextValue.getText().toString());
                    calculateWorkings();
                }
                textViewTouchIsHuman = true;    
            }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count,
                    int after) {
                // TODO Auto-generated method stub

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before,
                    int count) {
                // TODO Auto-generated method stub

            }

          });

我使用setOnKeyListener，setOnClickListern，addtextchangedlistenr尝试，但我不能让任何人的工作？我希望这个问题让senese。感谢在进阶

I've tried using setOnKeyListener, setOnClickListern, addtextchangedlistenr but I can't get any of them to work? I hope that question makes senese. thank in adv.

推荐答案

为什么不做出TextWatcher的分配方法addTextChangedListener（）之外，然后分配了TextWatcher多个的EditText对象。

Why not make a TextWatcher outside of the assigning method addTextChangedListener() and then assign that TextWatcher to multiple EditText objects.

例如：

TextWatcher tw = new TextWatcher();
intTextValue.addTextChangedListener(tw);
otherEditText.addTextChangedListener(tw);
...
