本文介绍了Android的 - 的EditText中的ListView - 键盘的意外行为的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
由于过去两天即我已经创建的ListView 与自定义视图与<$ C我坚持问题$ C>变异SubLayout 这样的：
I am stuck with problem since last two days i.e. i have created ListView with Custom View with Variant SubLayout like:
问题：
- 当我点击
的EditText的货，其显示的软输入键盘，配有数字小键盘并立即集中丢失从
的EditText与字母键盘的变化。 （第一下面的截图）
- 在
的EditText的第二次集中优良工程，并采取数值，但同时其滚动按键的变化，从数字到 字母。 （第二下面的截图）
其实我能理解的问题是什么，它是不断变化的 显示/隐藏键盘，因为这种观点是每次更新 时间，所以我能做些什么的继续专注于的EditText 或prevent到 刷新上显示/隐藏键盘查看。
我的适配器code是：

这产品行SubLayouts从下面的文件创建。
SubLayouts of that Product Row is Creating from following files.
list_product_variant_single_row_view.xml
list_product_variant_single_row_view.xml
list_product_variant_multiple_row_view.xml
list_product_variant_multiple_row_view.xml
注意的：查看距离时的EditText清爽失去焦点 键盘是开放的。这就是为什么小键盘更改视图数字来 字母。我已经改变了的AndroidManifest.xml 与 安卓windowSoftInputMode =stateAlwaysHidden和 安卓configChanges =keyboardHidden |定位，但不工作 对我来说。
您的帮助，将AP preciated。
Your Help would be appreciated.
推荐答案
添加此行会在code：
Add this line on your code:
input.setRawInputType(Configuration.KEYBOARD_12KEY);
这将只显示数字键盘。检查这个..
this will show only the numeric keyboard.check this..
