How to enable scrolling on a simple adapter on Google Glass X16 firmware

Question

After upgrading my Google Glass to XE16, my list that I created using a simple adapter can no longer scroll. Is there a way to manually enable scrolling using the GDK or fix this problem?

Answer 1

My list also scrolled with the X16 update. You can create a scroll by following these steps:

In your action, onCreatemake sure that:

• set list selection mode
• set the clickable property to true.
• set list onItemClicklistener
• (. )

:

myListView = (ListView)findViewById(R.id.MY_LIST_VIEW);
if(myListView != null){
    myListView.setAdapter(mAdapter);
    myListView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);
    myListView.setClickable(true);

    myListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
         public void onItemClick(AdapterView<?> parent, View view, int position, long id){
            Log.d("MY_LOG", "click at position " + position);
         }
    });
}

mGestureDetector = createGestureDetector(this);

createGestureDetector() ( ). , , GDK, SWIPE_LEFT SWIPE_RIGHT. , listView myListView. , :

private GestureDetector createGestureDetector(Context context) {
    GestureDetector gestureDetector = new GestureDetector(context);
    //Create a base listener for generic gestures
    gestureDetector.setBaseListener( new GestureDetector.BaseListener() {
        @Override
        public boolean onGesture(Gesture gesture) {
            if (gesture == Gesture.TAP) { // On Tap, generate a new number
                return true;
            } else if (gesture == Gesture.TWO_TAP) {
                // do something on two finger tap
                return true;
            } else if (gesture == Gesture.SWIPE_RIGHT) {
                // do something on right (forward) swipe
                myListView.setSelection(myListView.getSelectedItemPosition()+1);
                return true;
            } else if (gesture == Gesture.SWIPE_LEFT) {
                // do something on left (backwards) swipe
                myListView.setSelection(myListView.getSelectedItemPosition()-1);
                return true;
            }
            return false;
        }
    });
    gestureDetector.setFingerListener(new GestureDetector.FingerListener() {
        @Override
        public void onFingerCountChanged(int previousCount, int currentCount) {
          // do something on finger count changes
        }
    });
    gestureDetector.setScrollListener(new GestureDetector.ScrollListener() {
        @Override
        public boolean onScroll(float displacement, float delta, float velocity) {
            // do something on scrolling

            return false;
        }
    });
    return gestureDetector;
}
