Multiple Listview row selection in ResourceCursorAdapter

292 views Asked by At

Im developing a sms application where the UI setup is something like this.A Message fragment is used to show each message thread as a conversation list and a ResoruceCursorAdapter is used to bind conversation to the listview.Depending up on the message thread i will create fragments and im loading this fragment to a viewpager. So that i can swipe through each message thread as a fragment.Now in to the problem.I want to add contexual action bar to select multiple messages from the listview .Here the problem i face is its not highlighting the correct list row.When ever i select the items in the listview only the listview in the last fragment is getting selected

 public class MessageAdapter extends ResourceCursorAdapter
    {

        private HashMap<Integer, Boolean> mSelection = new HashMap<Integer, Boolean>();


        public MessageAdapter( Context _context, final Uri uri, int layout )
        {


            super( _context, layout, getCursor( _context.getContentResolver(), uri ), true );
            Log.e( "first uri in adapter is ", "" + uri.toString() );
            origCursor = getCursor( _context.getContentResolver(), uri );
            this.queryHandler = new BackgroundQueryHandler( _context.getContentResolver() );

            this.defaultContactAvatar = _context.getResources().getDrawable( R.drawable.default_avatar );

            this.textSize = PreferencesActivity.getTextsize( _context );
            this.textColor = PreferencesActivity.getTextcolor( _context );
            this.convertNCR = PreferencesActivity.decodeDecimalNCR( _context );

            context = _context;

        }

        public void setNewSelection(int position, boolean value) {
            mSelection.put(position, value);
            notifyDataSetChanged();
        }

        public boolean isPositionChecked(int position) {
            Boolean result = mSelection.get(position);
            return result == null ? false : result;
        }

        public Set<Integer> getCurrentCheckedPosition() {
            return mSelection.keySet();
        }

        public void removeSelection(int position) {
            mSelection.remove(position);
            notifyDataSetChanged();
        }

        public void clearSelection() {

            }

        }

    }

Im not sure whether my getView() implementation is correct or not . And below one is the listview multichoise listener in the fragment

lvMessage.setChoiceMode( ListView.CHOICE_MODE_MULTIPLE_MODAL );
        lvMessage.setMultiChoiceModeListener( new MultiChoiceModeListener()
        {
            private int nr = 0;
            private int longClickposition;
          @Override
            public void onItemCheckedStateChanged(ActionMode mode, int position,
                                                  long id, boolean checked) {
                // Here you can do something when items are selected/de-selected,
                // such as update the title in the CAB
                MainActivity.pager.setScrollingEnabled( true );


              longClickposition=position;
              if (checked) {
                  nr++;
                  adapter.setNewSelection(position, checked);                    
              } else {
                  nr--;
                  adapter.removeSelection(position); 


              }

              mode.setTitle(nr + " selected");
        }

            @Override
            public boolean onActionItemClicked(ActionMode mode, MenuItem item) {
                // Respond to clicks on the actions in the CAB

                return false;
            }

            @Override
            public boolean onCreateActionMode(final ActionMode mode, Menu menu) {
                 nr = 0;
              //  inflater.inflate(R.menu.contextual_menu, menu);
                mode.getMenuInflater().inflate( R.menu.contextual_menu, menu );

                return true;

            }

            @Override
            public void onDestroyActionMode(ActionMode mode) {
                // Here you can make any necessary updates to the activity when
                // the CAB is removed. By default, selected items are deselected/unchecked.
               // Log.e("onDestroyActionMode","onDestroyActionMode");
              //  MainActivity.pager.setScrollingEnabled( true );
                adapter.clearSelection();

            }

            @Override
            public boolean onPrepareActionMode(ActionMode mode, Menu menu) {

                return false;
            }
        });

    }
