I have a custom ListView including a custom row_layout. After a longclick you get different options from the contextmenu. Depending on what option is chosen by the user I want to add an image/icon to the selected row in order to mark it.
I couldnt find an answer which covers exactly this use-case. I would appreciate a hint or some help or a tutorial for this case.
Thanks in advance.
Never mind I got to a solution by myself. I added a boolean variable to my ListItem - Class and the ImageView to the list_row_layout as well as a ImageView to my ViewHolder Class within the CustomAdapter class. So when a contextItem is clicked the boolean Attribute is set to true for the listItem which was clicked on.
Example Code:
@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
int itemPosition = info.position;
switch (item.getItemId()) {
case R.id.contextItem1:
listViewItems.get(itemPosition).setMarkerAttribute(true);
listView.setAdapter(new MyCustomListAdapter(context, listViewItems));
return true;
case R.id.contextItem2:
//do sth
return true;
case R.id.contextItem3:
//do sth
return true;
default:
return super.onContextItemSelected(item);
}
}
Hope this was useful to somebody, because a lot of examples only cover removing an item ...
