试试这个，它应该能满足你的需要:

editText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
    if (actionId == EditorInfo.IME_ACTION_DONE) {
       //do here your stuff f
       return true;
    }
    return false;
    } 
});

更多关于如何设置OnKeyListener，并让它监听Done按钮的细节。

首先将OnKeyListener添加到类的implements部分。然后添加OnKeyListener接口中定义的函数:

/*
 * Respond to soft keyboard events, look for the DONE press on the password field.
 */
public boolean onKey(View v, int keyCode, KeyEvent event)
{
    if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
        (keyCode == KeyEvent.KEYCODE_ENTER))
    {
        // Done pressed!  Do something here.
    }
    // Returning false allows other listeners to react to the press.
    return false;
}

给定一个EditText对象:

EditText textField = (EditText)findViewById(R.id.MyEditText);
textField.setOnKeyListener(this);

在Kotlin中处理它的基本方式是:

edittext.setOnEditorActionListener { _, actionId, _ ->
    if (actionId == EditorInfo.IME_ACTION_DONE) {
        callback.invoke()
        return@setOnEditorActionListener true
    }
    false
}

芬兰湾的科特林扩展

使用这个来调用edittext。onDone{/*action*/}在你的主代码。使您的代码更具可读性和可维护性

fun EditText.onDone(callback: () -> Unit) {
    setOnEditorActionListener { _, actionId, _ ->
        if (actionId == EditorInfo.IME_ACTION_DONE) {
            callback.invoke()
            return@setOnEditorActionListener true
        }
        false
    }
}

不要忘记在编辑文本中添加这些选项

<EditText ...
    android:imeOptions="actionDone"
    android:inputType="text"/>

如果你需要inputType="textMultiLine"支持，请阅读这篇文章

虽然大多数人都直接回答了这个问题，但我想更详细地阐述它背后的概念。首先，当我创建一个默认的登录活动时，我引起了IME的注意。它为我生成了一些代码，包括以下内容:

<EditText
  android:id="@+id/password"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:hint="@string/prompt_password"
  android:imeActionId="@+id/login"
  android:imeActionLabel="@string/action_sign_in_short"
  android:imeOptions="actionUnspecified"
  android:inputType="textPassword"
  android:maxLines="1"
  android:singleLine="true"/>

您应该已经熟悉了inputType属性。这只是通知Android需要的文本类型，如电子邮件地址、密码或电话号码。可能值的完整列表可以在这里找到。

It was, however, the attribute imeOptions="actionUnspecified" that I didn't understand its purpose. Android allows you to interact with the keyboard that pops up from bottom of screen when text is selected using the InputMethodManager. On the bottom corner of the keyboard, there is a button, typically it says "Next" or "Done", depending on the current text field. Android allows you to customize this using android:imeOptions. You can specify a "Send" button or "Next" button. The full list can be found here.

这样，您就可以通过定义TextView监听按下的动作按钮。EditText元素的OnEditorActionListener。在你的例子中:

editText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(EditText v, int actionId, KeyEvent event) {
    if (actionId == EditorInfo.IME_ACTION_DONE) {
       //do here your stuff f
       return true;
    }
    return false;
    } 
});

现在在我的例子中，我有android:imeOptions="actionUnspecified"属性。当您想在用户按enter键时尝试登录时，这很有用。在Activity中，你可以检测到这个标签，然后尝试登录:

    mPasswordView = (EditText) findViewById(R.id.password);
    mPasswordView.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView textView, int id, KeyEvent keyEvent) {
            if (id == R.id.login || id == EditorInfo.IME_NULL) {
                attemptLogin();
                return true;
            }
            return false;
        }
    });

如果你使用Android annotation https://github.com/androidannotations/androidannotations

您可以使用@EditorAction注释

@EditorAction(R.id.your_component_id)
void onDoneAction(EditText view, int actionId){
    if(actionId == EditorInfo.IME_ACTION_DONE){
        //Todo: Do your work or call a method
    }
}

试试这个，它应该能满足你的需要:

editText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
    if (actionId == EditorInfo.IME_ACTION_DONE) {
       //do here your stuff f
       return true;
    }
    return false;
    } 
});
