Use “ENTER” key on softkeyboard to initiation an Event

Question

I'm designing an android keyboard and am having difficulty with initiating an action command from the keyboard.

When I am using the Internet on my device and press enter after typing in a website, rather than going to a new page, a space is shown and no action is done. I'm not sure how to make my enter key become an action key when pressed.

Here's the code where I believe it should be altered:

@Override
public void onKey(int primaryCode, int[] keyCodes) {
    InputConnection ic = getCurrentInputConnection();
    switch (primaryCode) {

    case Keyboard.KEYCODE_SHIFT:
        handleShift();
        break;

    case 10:
        //Initiate enter event or new line depending on program being used
        break;
    }
}

Any help would be appreciated.

Alright, thanks to George Rappel - I was sent in the right direction. I found my solution in the online android source code - took some hunting for that. Below is the code for ENTER - where ENTER is the value 10.

case ENTER:

        final EditorInfo editorInfo = getCurrentInputEditorInfo();
        final int imeOptionsActionId = InputTypeUtils.getImeOptionsActionIdFromEditorInfo(editorInfo);
        if (InputTypeUtils.IME_ACTION_CUSTOM_LABEL == imeOptionsActionId) {
            // Enter used as submission
            ic.performEditorAction(editorInfo.actionId);
        } else if (EditorInfo.IME_ACTION_NONE != imeOptionsActionId) {
            // Not quite sure what this is for
            ic.performEditorAction(imeOptionsActionId);
        } else {
            // Enter being used as text
            ic.commitText(String.valueOf((char) primaryCode), 1);
        }
        break;

I also copied the necessary methods from the class InputTypeUtils.java found in the online android repository.

Sorry for not beeing able to answer, but i'm already happy to help some way. Good luck with your development :) — George, Sep 01 '15 at 11:20

You're using KEYCODE_SHIFT, which is actually the one to change the keyboard from upper to lower case. The Enter keycode should be KEYCODE_ENTER, and it's value is 66, not 10.

case 10 would be KEYCODE_3, the number 3, not enter. See here.

You have the right code, all you have to do is change the KEYCODE and add the lines of code you want.

@Override
public void onKey(int primaryCode, int[] keyCodes) {

    switch (primaryCode) {    
        case KeyEvent.KEYCODE_ENTER:
            // Enter has been pressed
        break;
    }
}

The real line is `KeyEvent.KEYCODE_ENTER`. Also, I don't know what lines of code goes in the case statement. That's my real issue :) – sometimes24 Aug 24 '15 at 17:40
@sometimes24 my mistake, sorry. But what exactly do you want? To press the ENTER key and start the event for another key? – George Aug 24 '15 at 17:57
Since it's a keyboard, when I press the ENTER key - I want to initiate an action button. I'm probably not explaining it clear so hopefully my example makes sense. If I am in the Internet application and am typing a hyperlink, I want, when I press ENTER, to initiate the search command vs. the space character I see instead (because it isn't programmed right). – sometimes24 Aug 26 '15 at 02:51

Thank you - that sent me in the right direction. I pasted my answer here. Just wanted to note - KeyEvent.KEYCODE_ENTER is 66 and it printed B when I used it on my app. They Keys are used based on their ASCII values. The number 10 (line feed) yields the right answer. – sometimes24 Sep 01 '15 at 04:32
