Android: Edit Text Go Button
提问by Corey Alexander
I have an Edit Text that is defined as follows.
我有一个定义如下的编辑文本。
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:maxLines="1"
android:inputType="text"
android:hint="@string/field_text"
android:id="@+id/field"
/>
I want to set a custom command so that when somebody clicks on the Done/Go button on the onscreen keyboard a button is clicked or just run the methods that are run by the button. I think this has something to do with ime options but I havent been able to figure out how they work. Thanks in advance for any help!
我想设置一个自定义命令，以便当有人单击屏幕键盘上的“完成/开始”按钮时，会单击一个按钮或仅运行该按钮运行的方法。我认为这与 ime 选项有关，但我无法弄清楚它们是如何工作的。在此先感谢您的帮助！

You want a combination of android:imeOptions and setOnEditorActionListener
你想要 android:imeOptions 和 setOnEditorActionListener 的组合
<EditText android:id="@+id/some_edittext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:imeOptions="actionSend">
</EditText>
some_edittext.setOnEditorActionListener(new OnEditorActionListener() {
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_SEND) {
some_button.performClick();
return true;
}
return false;
}
});
Obviously you should change actionSend to the action you want, and update IME_ACTION_SEND correspondingly.
显然，您应该将 actionSend 更改为您想要的操作，并相应地更新 IME_ACTION_SEND。

Take a look at the setImeActionLabelmethod (or imeActionLabeland imeActionIdattributes) and setOnEditorActionListenerto set a listener to respond to the events.
查看setImeActionLabel方法（或imeActionLabel和imeActionId属性）并setOnEditorActionListener设置侦听器以响应事件。
