The SearchView.OnQueryTextListener method, onQueryTextChange, starts when onPrepareOptionsMenu is called

Question

The SearchView.OnQueryTextListener method, onQueryTextChange , fires when onPrepareOptionsMenu is called after calling invalidateOptionsMenu() .

My SearchView OnQueryTextListener ..

 final private SearchView.OnQueryTextListener queryListener = new SearchView.OnQueryTextListener() { @Override public boolean onQueryTextChange(String newText) { loaderID = 1; Bundle args = new Bundle(); args.putInt("loaderID", loaderID); if(!TextUtils.isEmpty(newText)){ uri = Uri.parse(DataProvider.URIPREPEND + DataProvider.SEARCH + "/?" + newText); Log.d("D", "onQueryTextChange() Search URI: " + uri.toString()); } args.putParcelable("uri", uri); try{ Log.d("D", "onQueryTextChange() case: search"); fragment.onMessage(args); }catch (ClassCastException cce){ } return false; } @Override public boolean onQueryTextSubmit(String query) { // Toast.makeText(getActivity(), "Searching for: " + query + "...", Toast.LENGTH_SHORT).show(); return false; } }; 

It is called every time I call invalidateOptionsMenu () from inside onOptionsItemSelected () ..

 @Override public boolean onOptionsItemSelected(MenuItem item) { Bundle args; switch (item.getItemId()) { case android.R.id.home: uri = Uri.parse(DataProvider.URIPREPEND + DataProvider.BOOKMARKS); loaderID = 0; args = new Bundle(); args.putParcelable("uri", uri); args.putInt("loaderID", loaderID); try{ Log.d("D", "onOptionsItemSelected() case: home"); fragment.onMessage(args); invalidateOptionsMenu(); }catch (ClassCastException cce){ } return true; default: return super.onOptionsItemSelected(item); } } 

I manage SearchView in onCreateOptionsMenu() , which is called once, to my understanding. I am confused how onPrepareOptionsMenu() can do onQueryTextChange in my text module to call.

 @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.menu, menu); // Associate searchable configuration with the SearchView SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE); SearchView searchView = (SearchView) menu.findItem(R.id.searchactionbaritem).getActionView(); //searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName())); searchView.setOnQueryTextListener(queryListener); return super.onCreateOptionsMenu(menu); } @Override public boolean onPrepareOptionsMenu(Menu menu){ menu.setGroupEnabled(R.id.browse_group, true); menu.setGroupVisible(R.id.browse_group, true); menu.setGroupEnabled(R.id.recipe_group, false); menu.setGroupVisible(R.id.recipe_group, false); // home if (loaderID == 0) { Log.d("D", "mListFragment/onPrepareOptionsMenu() home"); menu.findItem(android.R.id.home).setEnabled(false).setIcon(R.drawable.ic_home_black_48dp); menu.findItem(R.id.browse).setEnabled(true).setIcon(R.drawable.ic_browse_all_white_48dp); } else { // browse_all or search if(uri.getQuery() != null){ // search Log.d("D", "mListFragment/onPrepareOptionsMenu() search"); menu.findItem(android.R.id.home).setEnabled(true).setIcon(R.drawable.ic_home_white_48dp); menu.findItem(R.id.browse).setEnabled(true).setIcon(R.drawable.ic_browse_all_white_48dp); }else{ // browse_all Log.d("D", "mListFragment/onPrepareOptionsMenu() browse_all"); menu.findItem(android.R.id.home).setEnabled(true).setIcon(R.drawable.ic_home_white_48dp); menu.findItem(R.id.browse).setEnabled(false).setIcon(R.drawable.ic_browse_all_black_48dp); } } return super.onPrepareOptionsMenu(menu); } 

If I remove invalidateOptionsMenu() , then my search widget works as expected. When it is, my search text listener is called even when I did not click on the search widget at all.

Answer 1

I deleted ...

  SearchView searchView = (SearchView) menu.findItem(R.id.searchactionbaritem).getActionView(); searchView.setOnQueryTextListener(queryListener); 

from onCreateOptionsMenu() and put it in onPrepareOptionsMenu() and it works fine again.

Hope this helps someone else. I think this has something to do with invalidateOptionsMenu() , breaking the association of SearchView with actionview.

Perhaps you can reference the following code somewhere in your code:

 toolbar.getMenu().clear(); 

This code removes the listener that you registered for SearchView. Thus, if so, then you must reregister the listener for searchView with the following code:

  searchView.setOnQueryTextListener(queryListener);
