查阅android  sdk说明

/**

* Set a special listener to be called when an action is performed

* on the text view. This will be called when the enter key is pressed,

* or when an action supplied to the IME is selected by the user. Setting

* this means that the normal hard key event will not insert a newline

* into the text view, even if it is multi-line; holding down the ALT

* modifier will, however, allow the user to insert a newline character.

设置在文本视图上执行操作时调用的特殊侦听器。

当按下enter键时，或当向IME提供的操作被用户选中时，将调用此操作。

设置这意味着正常的硬键事件不会在文本视图中插入新行，即使它是多行的;

然而，按住ALT修饰符将允许用户插入换行符。
