Android: catching action for keyboard enter button being pressed

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.

How to interact with android keyboard enter and rest of the button

I have an edit box which popup an android keyboard. What i want is on click of done button in the keyboard i want to display a message in the and if the user click rest of the buttons in-spite of done button the message should be clear. I have used this code but it doesn't work. Please help me to solve this out.
Code i have used
m_passwrdEditText.setOnKeyListener(new OnKeyListener()
{
public boolean onKey(View v, int keyCode, KeyEvent event)
{
if (keyCode == KeyEvent.KEYCODE_ENTER)
{
m_passwrdErrorText.setText("Test Project");
}
else
{
m_passwrdErrorText.setText("");
}
m_passwrdEditText.setTypeface(face);
return false;
}
});

return true from onKey() method.

when i click on "DONE" button on softkeybord how to go next activity android

Its is better to add some button in the layout as all android phones dont provide a consistent behaviour when using imeoptions.
This seems to be a bug. Different manufacturers make a customized keyboard for their phone which may not completely behave as the android standard keyboard. This issue has been raised before. Most people overcome this issue by either overiding the onKey event or using a TextWatcher class. A bug has been filed about this
http://code.google.com/p/android/issues/detail?id=2882
You can use a listener to check for imeoptions
incomeInput.setOnEditorActionListener(new EditText.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE){
//Do your stuff here
return true; // mark the event as consumed
}
return false;
}
}

You need to implement OnEditorActionListener interface.
Code looks like :
public class Main extends Activity implements OnEditorActionListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main1);
}
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_DONE) {
startActivity(new Intent());
return true;
}
return false;
}}

Use setOnKeyListener with your second EditText and in onKey method do something like this.
#Override
public boolean onKey(View v, int keyCode, KeyEvent event)
{
// TODO Auto-generated method stub
if(keyCode == KeyEvent.KEYCODE_ENTER && event.getAction() == KeyEvent.ACTION_DOWN)
performYourAction();
return false;
}
I hope it will be helpfull for you.

How to capture when user presses "Search Soft key" in android

How to capture when user presses "Search Soft key" in android.
Can we do it in onKeyDown() and checking the keycode?

Try this in your Activity code:
#Override
public boolean onKeyDown( int keyCode, KeyEvent event )
{
if ( event.getKeyCode() == KeyEvent.KEYCODE_SEARCH )
{
// Catch the search
// do something
// return true to consume press or false to pass it on
}
return super.onKeyDown( keyCode, event );
}

I think that you are right. You can check for the key code that is given in the following list.
And prefer to check this onKeyUp.
http://developer.android.com/reference/android/view/KeyEvent.html#KEYCODE_SEARCH

I've done something like this for capturing the search softkey when progress dialog is showing and it worked fine for me:
progressDialog.setOnKeyListener(new DialogInterface.OnKeyListener() {
#Override
public boolean onKey(DialogInterface dialog, int keyCode,
KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_SEARCH) {
return true;
}
return false;
}
});

Android: menu and back button stop working

For my android app I have multiple edittexts on the main screen. If i have the first edittext in focus the menu/back buttons operate fine, if i have any of the other edittexts in focus than neither of them work at all. I'm not doing anything special regarding the menu/back buttons relative to that edittext, i'm not sure what the cause is? Has anyone run into a similar issue and/or know of the cause/solution?
Thanks!

I was have the same problem and I found solution for I was have OnKeyListener that return true; when I change it to return false; the problem was fixed
my_editText.setOnKeyListener(new OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
// you can use the next line to ensure back button & menu button will return false
if (event.getKeyCode() == KeyEvent.KEYCODE_BACK || event.getKeyCode() == KeyEvent.KEYCODE_MENU) return false;
// any other key you don't want to call other listener for it
if (event.getKeyCode() == KeyEvent.KEYCODE_ENTER&& event.getAction() == KeyEvent.ACTION_UP) {
return true;
}
return false;
}
});
OnKeyListener.onKey(android.view.View, int, android.view.KeyEvent)

easy fix for me, I had removed the only keyboard app.
just install a keyboard app and the buttons worked again
