Android: catching action for keyboard enter button being pressed - android

I am trying to respond to pressing the enter button on a standard system on screen soft keybord, in numeric mode. keyboard appears on the screen when myCustomEditText class is given focus.
tried 2 approaches:
overriding onKeyDown():
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_ENTER) {
//do sth..
return true;
}
return super.onKeyDown(keyCode, event);
}
setting listener setOnKeyListener:
myCustomEditText.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_ENTER) {
onRightButtonClicked();
return true;
}
return false;
}
});
(also tried onKeyDown() in myCustomEditText as well, but with no effect)
problem is:
these aproaches above works for all the keys being pressed but for the enter key - the methods are not even being fired at all. (it's not a problem of bad KeyEvent.KEYCODE_...)
my question is:
why these methods are not being fired for enter key, but are for other keys, and how to listen to enter key being pressed properly?


You respond to ENTER differently than normal keys, try something like this:
editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
switch (actionId) {
case EditorInfo.IME_ACTION_DONE:
...
return true;
default:
return false;
}
}
});
You can specify which action is performed by ENTER by specifiying android:imeOptions in XML or by calling editText.setImeOptions(...) with one of the constants in EditorInfo. imeOptions also changes how the ENTER key looks! For example if you set imeOptions to actionSearch then the ENTER key will look like a search button.
You can find a list of all possible values for imeOptions along with a description here.

android: onKeyListener is not fired for ENTER key pressed for multiline EditText

I've found a lot of similar questions but all of them don't work for multilines EditText.
If i set inputType="text" EditText becomes singleline and returns are just not shown. I also need "Enter" button to be "Enter" button (not "Next" or "Done").
content.setOnKeyListener(new View.OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN &&
keyCode == KeyEvent.KEYCODE_ENTER)
doSmthSpecial();
return false;
}
});

I don't know why it is not invoking ENTER key event. but you can go for another method which serves you same purpose. use OnEditorActionListener.
editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
doSomethingSpecial();
return true;
}
});
this method is invoked when you press ENTER key on EditText.

i have also digged alot of time on internet for this question's solution then,i found this:
et.dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_ENTER));
et is you edit text.
this,worked like charm for me.

How to handle hardware search button android?

I am new to android, I have a small doubt regarding how to handle the hardware Keyboard and if I click the search button in any part of my application it should be handled means I need to pass the intent of search activity?
How I can reach this goal.

Try this,
#Override
public boolean onSearchRequested() {
// your stuff here
return false;
}

It will also trigger onKeyDown with a keyCode of KeyEvent.KEYCODE_SEARCH before calling onSearchRequested as stated above

Add a listener for your EditText to listen on the Search button as following:
myEditText.setOnKeyListener(new OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_SEARCH || keyCode == KeyEvent.KEYCODE_ENTER) {
//Do some stuff
}
//Leave the return value false to hide the SoftKeyboard if it is shown
return false;
}
});
For me, it happened before that the softkey search button is detected as Enter button not search. That's why I'm ORing them

How can I use the android landscape keyboard buttons?

I have an activity with two EditTexts. If, in landscape mode, I select the first EditText, the keyboard that is displayed has a "next" button which should allow me to type in the second EditText. Likewise, the second EditText has a "done" button, which I would like to handle for completing the activity. How can I handle the selection of these buttons?

There is fairly little documentation on how to solve this issue. I found a good solution here. Basically, you can add an IMEoption for each of the EditTexts:
For the first one:
android:imeOptions="actionNext"
For the second one:
android:imeOptions="actionDone"
To handle these in the code, try something like this:
EditText departureAddress, destinationAddress;
departureAddress = (EditText)findViewById(R.id.departure);
//Set the action of the "next" button to bring destinationAddress to focus
destinationAddress(new OnEditorActionListener(){
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_NEXT) {
destinationAddress.requestFocus();
}
return true;
}
});
destinationAddress = (EditText)findViewById(R.id.destination);
//Set the action of the "done" button to handle the map query
destinationAddress.setOnEditorActionListener(new OnEditorActionListener(){
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
//Handle map query
}
return true;
}
});

Handle edittexts onKeyListener?

I am creating login screen with 2 editTexts: etUsername and etPassword.
On the etUsername, user should input the username and press Enter to go to the edit text etPassword, then he inputs the password, press Enter to login. Here is my current code:
etUsername.setOnKeyListener(new OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_ENTER)) {
etPassword.requestFocus();
return true;
} else
return false;
}
});
etPassword.setOnKeyListener(new OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_ENTER)) {
loginToServer();
return true;
} else
return false;
}
});
But when I input the username, and then press Enter – the program tries to log in to the server.
In the debug mode, I saw that when I pressed Enter once (on the etUsername) then first: etUsername.onKey() is called and then etPassword.onKey() is also called !
How can I modify the code so that the ENTER event is only processed once for the current field?

Before you check which key is pressed, try adding a check for which key event occurs. I would guess that it first triggers on the key-down event, then you move focus to the second text field, and here it also triggers on the key-up event.
See here for an example on how to check both the event type and key: Use "ENTER" key on softkeyboard instead of clicking button
I'm not 100% sure of this, but it is worth a try :-)

How to catch a "Done" key press from the soft keyboard

how do I catch specific key events from the soft keyboard?
specifically I'm interested in the "Done" key.

I am not quite sure which kind of listener was used in the accepted answer.
I used the OnKeyListener attached to an EditText and it wasn't able to catch next nor done.
However, using OnEditorActionListener worked and it also allowed me to differentiate between them by comparing the action value with defined constants EditorInfo.IME_ACTION_NEXT and 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.
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:
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.
Reference: http://developer.android.com/reference/android/view/KeyEvent.html

Note: This answer is old and no longer works. See the answers below.
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"
if (event.getKeyCode() == KeyEvent.FLAG_EDITOR_ACTION)
//your code here
Find the docs here.

just do like this :
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.
// 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;
}

Note : inputtype mention in your edittext.
<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;
}
});

you can override done key event by this method:
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;
}
});

KOTLIN version:
<EditText android:id="#+id/edit_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="text" />
Do not forget to set android:inputType.
// Get reference to EditText.
val editText = findViewById<EditText>(R.id.edit_text)
editText.setOnEditorActionListener { _, actionId: Int, _ ->
if (actionId == EditorInfo.IME_ACTION_DONE) {
// Do your logic here.
true
} else {
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.
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"
so hidding keyboard with Done button, EditText should look like this:
<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" />

IME_MASK_ACTION is 255, while the received actionId is 6, and my compiler does not accept
if (actionId & EditorInfo.IME_MASK_ACTION)
which is an int. What is the use of &-ing 255 anyway? So the test simply can be
public boolean onEditorAction(TextView view, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE)
...
