Perform Search inside a ListView with SimpleCursorAdapter

  • 772

Hi, I have the following code but it doesn't work and it doesn't throw me any error, could you guide me? If anyone has encountered this problem. Thank you so much

 ListView mContactsList = (ListView) view.findViewById(R.id.listagenda);
      mContactsList.setAdapter(mAdapter);
      mContactsList.setTextFilterEnabled(true);
      mContactsList.setFastScrollEnabled(true);

    numpad.addTextChangedListener(new TextWatcher() {

        public void onTextChanged(CharSequence arg0, int arg1, int arg2,
                                  int arg3) {
            String text = numpad.getText().toString();
            Toast.makeText(getContext(),text,Toast.LENGTH_LONG).show();
            ContactsListActivity.this.mAdapter.getFilter().filter(text);


        }

        public void beforeTextChanged(CharSequence arg0, int arg1,
                                      int arg2, int arg3) {

        }

        public void afterTextChanged(Editable arg0) {
            ListView av = (ListView) view.findViewById(R.id.listagenda);
            SimpleCursorAdapter filterAdapter = (SimpleCursorAdapter)av.getAdapter();
            filterAdapter.getFilter().filter(arg0.toString());

        }
    });

    I found the solution:

    numpad.addTextChangedListener(new TextWatcher() {

        public void onTextChanged(CharSequence arg0, int arg1, int arg2,
                                  int arg3) {

            Log.d(null, "Filter:"+arg0);

                mAdapter.getFilter().filter(arg0);

        }

        public void beforeTextChanged(CharSequence arg0, int arg1,
                                      int arg2, int arg3) {

        }

        public void afterTextChanged(Editable arg0) {

        }
    });
    mAdapter.setFilterQueryProvider(new FilterQueryProvider() {

        public Cursor runQuery(CharSequence constraint) {
            Log.d(null, "runQuery constraint:"+constraint);
            //uri, projection, and sortOrder igual que antes
            //El selection debes cambiarlo segun la busqueda que quieras hacer con la variable constraint
            String SELECTIONS_SEARCH = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " like'%" + constraint + "%' OR "+ ContactsContract.CommonDataKinds.Phone.NUMBER + " like'%" + constraint + "%'";
            Cursor cur = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, PHONE_PROJECTION, SELECTIONS_SEARCH, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME_PRIMARY
                    + " COLLATE NOCASE ASC");
            return cur; //now your adapter will have the new filtered content
        }

    });
