Android - 处理“输入"在 EditText 中 [英] Android - Handle "Enter" in an EditText

问题描述

我想知道是否有一种方法可以处理用户在输入 EditText 时按下 Enter，类似于 onSubmit HTML 事件.

I am wondering if there is a way to handle the user pressing Enter while typing in an EditText, something like the onSubmit HTML event.

还想知道是否有一种方法可以操纵虚拟键盘，使完成"按钮被标记为其他内容(例如开始")并在单击时执行特定操作(再次，例如 onSubmit).

Also wondering if there is a way to manipulate the virtual keyboard in such a way that the "Done" button is labeled something else (for example "Go") and performs a certain action when clicked (again, like onSubmit).

是的.

也想知道有没有办法操纵虚拟键盘这样完成"按钮是标记其他东西(例如"Go") 并执行某个动作单击时(再次，如 onSubmit).

Also wondering if there is a way to manipulate the virtual keyboard in such a way that the "Done" button is labeled something else (for example "Go") and performs a certain action when clicked (again, like onSubmit).

也是.

您需要查看 android:imeActionId 和 android:imeOptions 属性，加上 setOnEditorActionListener() 方法，全部在 TextView 上.

要将完成"按钮的文本更改为自定义字符串，请使用:

For changing the text of the "Done" button to a custom string, use:

mEditText.setImeActionLabel("Custom text", KeyEvent.KEYCODE_ENTER);
