我的工作环境是Eclipse的heliose，Android 1.6的如何添加editText.addTextChangedListener在TableLayout
我创建了一个tableLayout列和行成功添加，每个单元都有一个TextView的，一个EditText上和我有一个问题访问每个单元格并需要将addTextChangedListener添加到单元格内的每个editText。所以我需要将英文文本更改为提示文本。请提出一个解决方案

你为什么要以编程方式做这件事？相反，您可以为ListView创建一个自定义适配器，每个项目都有一个edittext和textview，这在设计和开发部分都很容易。 – 2012-04-12 07:09:58
感谢您的回复，实际上我们正在创建一个填字游戏应用程序，所以我就是这样做的。这个填字游戏的字体是古吉拉特文字。所以需要更改用户输入的文字，它是一种涉及此处的音译。 – 2012-04-12 09:49:25
这意味着你有行* cols屏幕，比如说4 * 4 – 2012-04-12 10:04:49
