Question

I would like to get rid of the Android Market filter android.hardware.touchscreen in order to allow the download of my app on non-touchscreen devices (device with keyboard navigatio only).

There are not so much devices which are not touchscreen but there are some…

My app works with keyboard except the ListViews… I would like the user to be able to navigate in my ListView only with the keyboard. Namely, he must be able to scroll in the listView => the different cells have to be highlighted successively when he scrolls.

How to do that ?

Thanks !!

Maybe you can create a onKeyListener. It goes something like this:

private class myListKeyListener implements onKeyListener {
    @Override
    public boolean onKey(View arg0, int arg1, KeyEvent arg2) {

        if (KeyEvent.ACTION_DOWN == arg2.getAction()) {
            switch (arg1) {
            case KeyEvent.KEYCODE_DPAD_UP: {

                    int i = list.getSelectedItemPosition();
                    if (i > 0)
                        i--;
                    list.setSelection(i);
                    break;}
}

the same thing for DOWN, RIGHT, LEFT…you can do what you want with it

After that attach listener to your list in onCreate method:

list.setOnKeyListner(new MyListKeyListener);

Hope it helps you 😉
