More details on how to set the OnKeyListener, and have it listen for the Done button.

First add OnKeyListener to the implements section of your class. Then add the function defined in the OnKeyListener interface:

<pre><code>/*
 * 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) &amp;&amp;
 (keyCode == KeyEvent.KEYCODE_ENTER))
 {
 // Done pressed! Do something here.
 }
 // Returning false allows other listeners to react to the press.
 return false;
}
</code></pre>

Given an EditText object:

<pre><code>EditText textField = (EditText)findViewById(R.id.MyEditText);
textField.setOnKeyListener(this);
</code></pre>

I know this question is old, but I want to point out what worked for me.

I tried using the sample code from the <a href="https://developer.android.com/training/keyboard-input/style.html">Android Developers website</a> (shown below), but it didn't work. So I checked the EditorInfo class, and I realized that the IME_ACTION_SEND integer value was specified as <code>0x00000004</code>.

Sample code from Android Developers:

<pre><code>editTextEmail = (EditText) findViewById(R.id.editTextEmail);
editTextEmail
 .setOnEditorActionListener(new OnEditorActionListener() {
 @Override
 public boolean onEditorAction(TextView v, int actionId,
 KeyEvent event) {
 boolean handled = false;
 if (actionId == EditorInfo.IME_ACTION_SEND) {
 /* handle action here */
 handled = true;
 }
 return handled;
 }
 });
</code></pre>

So, I added the integer value to my <code>res/values/integers.xml</code> file.

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;resources&gt;
 &lt;integer name="send"&gt;0x00000004&lt;/integer&gt;
&lt;/resources&gt;
</code></pre>

Then, I edited my layout file <code>res/layouts/activity_home.xml</code> as follows

<pre><code>&lt;EditText android:id="@+id/editTextEmail"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:imeActionId="@integer/send"
 android:imeActionLabel="@+string/send_label"
 android:imeOptions="actionSend"
 android:inputType="textEmailAddress"/&gt;
</code></pre>

And then, the sample code worked.

});
</code></pre>

blocks|key|1368343|text|虽然大多数人已经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，当我创建了一个默认的Login+Activity时，我注意到了IME。它为我生成了一些代码，其中包括以下内容：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1368344|<EditText
++android:id="@%2Bid/password"
++android:layout_width="match_parent"
++android:layout_height="wrap_content"

++android:imeActionId="@%2Bid/login"
++android:imeActionLabel="@string/action_sign_in_short"
++android:imeOptions="actionUnspecified"
++android:inputType="textPassword"
++android:maxLines="1"
++android:singleLine="true"/>|code-block|syntax|javascript|1368345|您应该已经熟悉了inputType属性。这只是通知Android预期的文本类型，如电子邮件地址、密码或电话号码。可以在here中找到可能值的完整列表。|offset|length|1368346|然而，正是imeOptions="actionUnspecified"属性让我不明白它的用途。当使用InputMethodManager选择文本时，Android允许你与屏幕底部弹出的键盘进行交互。在键盘的下角有一个按钮，通常会显示“下一步”或“完成”，具体取决于当前的文本字段。Android允许你使用android:imeOptions进行定制。您可以指定“发送”按钮或“下一步”按钮。完整的列表可以在here上找到。|style|CODE|1368347|这样，您就可以通过为EditText元素定义一个TextView.OnEditorActionListener来监听操作按钮上的按下情况。如您的示例所示：|1368348|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;
++++}+
});|1368349|现在在我的示例中，我有了android:imeOptions="actionUnspecified"属性。当您想要在用户按enter键时尝试登录时，此功能非常有用。在您的活动中，您可以检测到此标记，然后尝试登录：|1368350|++++mPasswordView+=+(EditText)+findViewById(R.id.password);

While most people have answered the question directly, I wanted to elaborate more on the concept behind it. First, I was drawn to the attention of IME when I created a default Login Activity. It generated some code for me which included the following:

<pre><code>&lt;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"/&gt;
</code></pre>

You should already be familiar with the inputType attribute. This just informs Android the type of text expected such as an email address, password or phone number. The full list of possible values can be found <a href="https://developer.android.com/reference/android/widget/TextView.html#attr_android%3AinputType" rel="noreferrer">here</a>. 

It was, however, the attribute <code>imeOptions="actionUnspecified"</code> 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 <code>InputMethodManager</code>. 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 <code>android:imeOptions</code>. You can specify a "Send" button or "Next" button. The full list can be found <a href="https://developer.android.com/reference/android/widget/TextView.html#attr_android:imeOptions" rel="noreferrer">here</a>.

With that, you can then listen for presses on the action button by defining a <code>TextView.OnEditorActionListener</code> for the <code>EditText</code> element. As in your example:

<pre><code>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;
 } 
});
</code></pre>

Now in my example I had <code>android:imeOptions="actionUnspecified"</code> attribute. This is useful when you want to try to login a user when they press the enter key. In your Activity, you can detect this tag and then attempt the login:

<pre><code> 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;
 }
 });
</code></pre>
