Note:This answer is old and no longer works. See the answers below.
注意：这个答案是旧的，不再有效。请参阅下面的答案。
You catch the KeyEvent and then check its keycode. FLAG_EDITOR_ACTION is used to identify enter keys that are coming from an IME whose enter key has been auto-labelled "next" or "done"
您捕获 KeyEvent，然后检查其键码。FLAG_EDITOR_ACTION 用于识别来自 IME 的输入键，输入键已自动标记为“下一步”或“完成”
if (event.getKeyCode() == KeyEvent.FLAG_EDITOR_ACTION)

I am not quite sure which kind of listener was used in the accepted answer.
I used the OnKeyListenerattached to an EditTextand it wasn't able to catch next nor done.
我不太确定在接受的答案中使用了哪种听众。我使用了OnKeyListener附加到 anEditText并且它无法捕捉 next 或 done。
However, using OnEditorActionListenerworked and it also allowed me to differentiate between them by comparing the action value with defined constants EditorInfo.IME_ACTION_NEXTand EditorInfo.IME_ACTION_DONE.
但是，使用OnEditorActionListenerwork 和它也允许我通过将操作值与定义的常量EditorInfo.IME_ACTION_NEXT和EditorInfo.IME_ACTION_DONE.
editText.setOnEditorActionListener(new OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if ((actionId & EditorInfo.IME_MASK_ACTION) != 0) {
doSomething();
return true;
}
else {
return false;
}
}
});

@Swato's answer wasn't complete for me (and doesn't compile!) so I'm showing how to do the comparison against the DONE and NEXT actions.
@Swato 的回答对我来说并不完整（并且无法编译！）所以我展示了如何与 DONE 和 NEXT 操作进行比较。
editText.setOnEditorActionListener(new OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView view, int actionId, KeyEvent event) {
int result = actionId & EditorInfo.IME_MASK_ACTION;
switch(result) {
case EditorInfo.IME_ACTION_DONE:
// done stuff
break;
case EditorInfo.IME_ACTION_NEXT:
// next stuff
break;
}
}
});
Also I want to point out that for JellyBean and higher OnEditorActionListener is needed to listen for 'enter' or 'next' and you cannot use OnKeyListener. From the docs:
另外我想指出，对于 JellyBean 和更高版本的 OnEditorActionListener 需要侦听“输入”或“下一步”，并且您不能使用 OnKeyListener。从文档：
As soft input methods can use multiple and inventive ways of inputting text, there is no guarantee that any key press on a soft keyboard will generate a key event: this is left to the IME's discretion, and in fact sending such events is discouraged. You should never rely on receiving KeyEvents for any key on a soft input method.
由于软输入法可以使用多种创造性的文本输入方式，因此不能保证软键盘上的任何按键按下都会生成按键事件：这由 IME 自行决定，实际上不鼓励发送此类事件。对于软输入法上的任何键，您永远不应依赖接收 KeyEvent。

just do like this :
就这样做：
editText.setOnEditorActionListener(new OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView view, int actionId, KeyEvent event) {
if(actionId == EditorInfo.IME_ACTION_DONE)
{
//Do Something
}
return false;
}
});

etSearchFriends = (EditText) findViewById(R.id.etSearchConn);
etSearchFriends.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
// If the event is a key-down event on the "enter" button
if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
(keyCode == KeyEvent.KEYCODE_ENTER)) {
Toast.makeText(ACTIVITY_NAME.this, etSearchFriends.getText(),Toast.LENGTH_SHORT).show();
return true;
}
return false;
}
});

To catch a “Done” key press from the soft keyboard override Activity's onKeyUp method. Setting a OnKeyListener listener for a view won't work because key presses in software input methods will generally not trigger the methods of this listener, this callback is invoked when a hardware key is pressed in the view.
要从软键盘中捕获“完成”按键，请覆盖 Activity 的 onKeyUp 方法。为视图设置 OnKeyListener 侦听器将不起作用，因为软件输入法中的按键按下通常不会触发此侦听器的方法，当在视图中按下硬件键时会调用此回调。
// Called when a key was released and not handled by any of the views inside of the activity.
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
switch (keyCode) {
case KeyEvent.KEYCODE_ENTER:
// code here
break;
default:
return super.onKeyUp(keyCode, event);
}
return true;
}
回答by Farhan
you can override done key event by this method:
您可以通过此方法覆盖完成的键事件：
editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
// do your stuff here
}
return false;
}
});

Note : inputtype mention in your edittext.
注意：在您的编辑文本中提及输入类型。
<EditText android:id="@+id/select_category"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="text" >
edittext.setOnEditorActionListener(new OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if ((actionId & EditorInfo.IME_MASK_ACTION) == EditorInfo.IME_ACTION_DONE) {
//do something here.
return true;
}
return false;
}
});

I have EditText that searches names, and it automatically shows results below in ListView. SoftInput keyboard only showed "next" button and enter sign - which didn't do anything. I wanted only Done button (no next or enter sign) and also I wanted it when it was pressed, it should close keyboard because user should see results below it.
我有搜索名称的 EditText，它会自动在 ListView 中显示下面的结果。SoftInput 键盘只显示“下一步”按钮并输入符号 - 这没有做任何事情。我只想要完成按钮（没有下一个或输入符号），而且我想要它被按下时，它应该关闭键盘，因为用户应该看到它下面的结果。
Solution that I found /by Mr Cyril Mottier on his blog/ was very simple and it worked without any additional code: in xml where EditText is located, this should be written: android:imeOptions="actionDone"
我发现/由 Cyril Mottier 先生在他的博客上找到的解决方案非常简单，它无需任何额外代码即可工作：在 EditText 所在的 xml 中，应该这样写：android:imeOptions="actionDone"
so hidding keyboard with Done button, EditText should look like this:
所以用“完成”按钮隐藏键盘，EditText 应该是这样的：
<EditText
android:id="@+id/editText1central"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/imageView1"
android:layout_toLeftOf="@+id/imageView2tie"
android:ems="10"
android:imeOptions="actionDone"
android:hint="@string/trazi"
android:inputType="textPersonName" />
