Searchview Auto Submit After Couple Of Letters Or Seconds

I have a android.support.v7.widget.SearchView that I use like this: if (query == null) { // Associate searchable configuration with the SearchView SearchManager searchManage

Solution 1:

Use a editText instead of the searchView and add a textWatcher similar to this:

searchView.addTextChangedListener(new TextWatcher() {
        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {

            // Insert your code here for submitting

        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

            // TODO Auto-generated method stub
        }

        @Override
        public void afterTextChanged(Editable s) {

            // TODO Auto-generated method stub
        }
    });

Solution 2:

Use this code, I just had the same problem and figured out how to implement it.

The code is commented and I believe it is self explanatory, otherwise feel free to ask anything!

@OverridepublicvoidonCreateOptionsMenu(Menu menu, MenuInflater inflater) {

    MenuItem searchBackupsButton = menu.findItem(R.id.action_search);
    searchView = (SearchView) searchBackupsButton.getActionView();

    // Set menu items visible
    searchBackupsButton.setVisible(true);
    setupSearchView(searchBackupsButton);
}



privatevoidsetupSearchView(final MenuItem searchItem) 
{
    if (isAlwaysExpanded()) 
    {
        searchView.setIconifiedByDefault(false);
    } 
    else 
    {
        searchItem.setShowAsActionFlags(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
    }

    searchView.setOnQueryTextListener(newOnQueryTextListener() {
        @OverridepublicbooleanonQueryTextSubmit(String query)
        {
            // If you are using a pager view (tabbed) you can get the current one hereif(pager.getCurrentItem() == 0)
            {
                // do your searches here// Hide the keyboard
                searchView.clearFocus();

            }
            // same as aboveelseif(pager.getCurrentItem() == 1)
            {
                // do your searches here// Hide the keyboard
                searchView.clearFocus();
            }
            returntrue;
        }

        @OverridepublicbooleanonQueryTextChange(String newText) 
        {
            // Here for each key pressed there will be a timer starting from X and drecrementing.// When the timer reaches zero it will perform a search// So, lets say the user inserted letter 'a'. 500ms later, if the user didnt input// anything else the search for query 'a' will be made.Log.d(TAG, "Query: " + newText);

            // if there is already a count down running, cancel it and start a new oneif(isCountDownTimerRunning)
            {
                countDownTimer.cancel();
            }

            // There is nothing to search for, show the full list!// This is usefull when the user presses the cross 'x' on the search view// Then the full list will be shown again// Or when the user presses backspace until it clears the searchviewif("".equals(newText) || newText == null)
            {
                // check what current fragment is on the pagerif(pager.getCurrentItem() == 0)
                {
                    // There is nothing to search for, show the full list!
                }
                // if cloud backupselseif(pager.getCurrentItem() == CLOUD_BACKUPS_FRAGMENT_POSITION)
                {
                    // There is nothing to search for, show the full list!
                }
            }
            else
            {
                // Get the active fragmentif(pager.getCurrentItem() == 0) 
                    countDownTimer = timedSearchQuery(TIME_INTERVAL_BETWEEN_KEY_PRESSED_AND_SEARCH, newText, 0);
                elseif(pager.getCurrentItem() == 1)
                    countDownTimer = timedSearchQuery(TIME_INTERVAL_BETWEEN_KEY_PRESSED_AND_SEARCH, newText, 1);
            }
            returnfalse;
        }
    });
}

    privateCountDownTimertimedSearchQuery(long timeInMillis, final String searchFor, final int fragment)
{           
    countDownTimer = newCountDownTimer(timeInMillis, timeInMillis/2) { 
        @OverridepublicvoidonTick(long millisUntilFinished) {
        }
        @OverridepublicvoidonFinish() {
            if(fragment == 0)
                // do your search on fragment @ position zero;elseif(fragment == 1)
                // do your search on fragment  2 position 1// and so on...
        }
    };

    countDownTimer.start();
    isCountDownTimerRunning = true;

    return countDownTimer;
