DPad Nav Preference Screen Google TV

Question

I have preferences created from XML and preferenceFragment and left-hand navigation. When I choose "Settings" my pref fragments comes out...I can use DPad to move up and down, when there are no more choices on the bottom, the cursor stops (desired behavior), but when I move up the list, the cursor continues over to the left-hand nav. I want it to stop at the top. Below is my pref_screen xml. My left hand nav is created code side. I have no idea how to work DPad logic into this. I also want to restrict the DPad from moving cursor over to left-hand navigation menu if in settings fragment.

Answer 1

I had to figure out a way to depict the positions and children to handle dpad. Here is the code I wrote to handle this:

@Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState){
    View v = inflater.inflate(R.layout.settings_tile, null);
    final ImageView closeBtn = (ImageView) v.findViewById(R.id.settingsCloseButton);
    closeBtn.setFocusable(true);
    closeBtn.setOnClickListener(this);
    closeBtn.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                v.setOnKeyListener(new OnKeyListener() {
                    @Override
                    public boolean onKey(View v, int keyCode, KeyEvent event) {
                        if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) {
                            return false;
                        }
                        if (event.getAction() == KeyEvent.ACTION_DOWN) {
                            return !(KeyEvent.KEYCODE_DPAD_DOWN == keyCode);
                        }
                        return false;
                    }
                });
            } else {
                v.setOnKeyListener(null);
            }

        }
    });
    final ListView lv = (ListView) v.findViewById(android.R.id.list);
    lv.setOnKeyListener(new OnKeyListener() {
        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            // TODO Auto-generated method stub
            if (event.getAction() == KeyEvent.ACTION_DOWN) {
                switch(keyCode) {
                    case KeyEvent.KEYCODE_DPAD_DOWN:
                        return !(lv.getSelectedItemPosition() < lv.getCount() - 1);
                    case KeyEvent.KEYCODE_DPAD_UP:
                        if (lv.getSelectedItemPosition() == 1) {
                            closeBtn.requestFocus();
                        }
                        return lv.getSelectedItemPosition() == 1;
                    case KeyEvent.KEYCODE_DPAD_RIGHT:
                        return true;    
                }
                return false;
            }
            return false;
        }
    });
    consumeKeyEvent(v);
    return v;
}

private void consumeKeyEvent(Object obj) {
    if (obj instanceof ViewGroup) {
        for (int i = 0; i < ((ViewGroup)obj).getChildCount(); i++) {
            consumeKeyEvent(((ViewGroup)obj).getChildAt(i));
        }
        return;
    }
    ((View)obj).setOnKeyListener(new OnKeyListener() {

        @Override
        public boolean onKey(View v, int keyCode, KeyEvent event) {
            Log.i(DEBUG_TAG, "Event consumed, " + keyCode);
            return false;
        }
    });
}
