以编程方式在软键盘上禁用选项

Question

I want to know that if possible disable hide option on a soft-keyboard programmatically.

Hide Option

Answer 1

//Disable return button
@Override
public boolean dispatchKeyEvent(KeyEvent event){

    if(event.getAction() == KeyEvent.ACTION_DOWN) {
        switch (event.getKeyCode()) {
            case KeyEvent.KEYCODE_BACK:
                return true;
        }
    }

    return super.dispatchKeyEvent(event);
}

This code disable, as you can see, the return button. For your case you should replace KEYCODE_BACK with another constant . I don't know for sure if it is one for option button but you can check the list right here: https://developer.android.com/reference/android/view/KeyEvent.html
