I have a ListFragment that I populate with a ContentProvider.
I need to attach a gesture listener to each of them so that when the user swipes to right, the item is removed from the list.
Below is all I have in my ListFragment at the moment.
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
String selection = l.getItemAtPosition(position).toString();
Toast.makeText(v.getContext(), selection + "", Toast.LENGTH_LONG).show();
Log.d("TodoListFragment", selection+ "");
}
How would I attach the gesture detection and listening?
I have done some research and found this piece of code:
class MyGestureDetector extends SimpleOnGestureListener {
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
try {
if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH)
return false;
// right to left swipe
if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
Log.d("Swipe", "Left");
} else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
Log.d("Swipe", "Right");
}
} catch (Exception e) {
// nothing
}
return false;
}
}
Can anyone tell me how to implement it? (Not the deleting part but just the implementation)
I faced some problem throughout i fixed issue using below answer.
it works perfectly.
class SideIndexGestureListener extends GestureDetector.SimpleOnGestureListener {
@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
Log.d("Scrolled- fragment ", "Scrolling");
return super.onScroll(e1, e2, distanceX, distanceY);
}
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
final GestureDetector gestureDetector = new GestureDetector(getActivity(),
new SideIndexGestureListener());
View.OnTouchListener gestureListener = new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}
};
getListView().setOnTouchListener(gestureListener);
try {
adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.simple_list_item_single_choice, elementos);
setListAdapter(adapter);
getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
}catch (Exception e){
}
