Gboard Like Search Bar In Android Ime

I want to create a search bar like Gboard inside keyboard (Android IME) as shown in picture. Gboard Sample : I have implemented an edittext on Keyboardview.xml as shown in picture

Solution 1:

So, I got a clue to solve this, from Abdul Wajid's comment above.

I use this LatinIME. Just need to update this line

publicvoidonEvent(final Event event) {
        final InputTransaction completeInputTransaction =
                mInputLogic.onCodeInput(mSettings.getCurrent(), event);
        updateStateAfterInputTransaction(completeInputTransaction);
        mKeyboardSwitcher.onEvent(event, getCurrentAutoCapsState(), getCurrentRecapitalizeState());
}

stop commit the event key pressed with some logical case,

publicvoidonEvent(final Event event) {
    if (mEditField.isFocused()){
        Log.d("LatinIME : field focused", "On Event: " + event.getTextToCommit() );
        mEditField.append(event.getTextToCommit());
    } else {
        final InputTransaction completeInputTransaction =
                mInputLogic.onCodeInput(mSettings.getCurrent(), event);
        updateStateAfterInputTransaction(completeInputTransaction);
        mKeyboardSwitcher.onEvent(event, getCurrentAutoCapsState(), getCurrentRecapitalizeState());
    }
}

and done, you can control the event type that pressed.
