SearchView :Triggering onQueryTextChange on Collapsing of the searchView

searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
search(newText);
return true;
}
});
I don't want search(newText) to be executed when searchview collapses.
I tried
if(searchView.isShown) search(newText);
and
if(!searchView.isIconified) search(newText);
but when I close the searchview, searchView.isShown and searchView.isIconified values will be updated after triggering onQueryTextChange.
My onCreateOptionMenu code:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_contacts, menu);
addContactMenuItem = menu.findItem(R.id.action_add_contact);
searchViewMenuItem = menu.findItem(R.id.action_search);
searchView = (SearchView) MenuItemCompat.getActionView(searchViewMenuItem);
MenuItemCompat.setOnActionExpandListener(searchViewMenuItem, new MenuItemCompat.OnActionExpandListener() {
#Override
public boolean onMenuItemActionExpand(MenuItem item) {
addContactMenuItem.setVisible(false);
if (contactListAdapter != null)
contactListAdapter.getFilter().filter(searchView.getQuery());
return true;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem item) {
addContactMenuItem.setVisible(true);
contactListAdapter.performGroupBasedFiltering(groupSpinner.getAdapter().getItemId(groupSpinner.getSelectedItemPosition()));
return true;
}
});
return true;
}
Please help me out! Thanks in advance.

Try this use setOnActionExpandListener
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.search_menu, menu);
MenuItem item = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
searchView.setOnQueryTextListener(this);
MenuItemCompat.setOnActionExpandListener(item,
new MenuItemCompat.OnActionExpandListener() {
#Override
public boolean onMenuItemActionExpand(MenuItem menuItem) {
// perform your action here
return true;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem menuItem) {
// perform your action here
return true;
}
});
return true;
}
EDIT
as per your comment
I need search(newText) not to be executed on collapsing.
than set this searchView.setOnQueryTextListener(null); when you don't need

Android Firebase - Error in searchbar

I'm doing a search bar in my android app with Firebase.
This is my database
and this is my code:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_menu, menu);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB){
SearchManager manager = ( SearchManager ) getSystemService ( Context.SEARCH_SERVICE );
SearchView search = (SearchView) menu.findItem(R.id.action_search).getActionView();
search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));
search.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
mDatabase.child ( "Blog" ).equalTo ( query );
return true;
}
#Override
public boolean onQueryTextChange(String query) {
return false;
}
});
}
return super.onCreateOptionsMenu(menu);
}
I need to research in "title", "desc" and "username" but I see that I did something wrong, because it doesn't work. What should I do? Thanks in advance!

#Override
public boolean onQueryTextSubmit(String query) {
mDatabase.child( "Blog" ).child("title").equalTo( query );
return true;
}

Not able to get the text entered in search bar in android

I am trying to implement search functionality for my android application. I am not able to get the text entered in the search bar. I have tried all the methods mentioned in SO. Please let me know what mistake am I doing. I am struggling from a long time.
my code:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater = getActivity().getMenuInflater();
inflater.inflate(R.menu.menu_activity_for_fragments, menu);
SearchManager searchManager = (SearchManager)
getActivity().getSystemService(Context.SEARCH_SERVICE);
searchMenuItem = menu.findItem(R.id.search);
searchView = (SearchView) searchMenuItem.getActionView();
searchView.setSearchableInfo(searchManager.
getSearchableInfo(getActivity().getComponentName()));
enteredText = (String) searchView.getQuery();
Log.d("iFocus", "" + enteredText);
searchView.setSubmitButtonEnabled(true);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
Log.d("iFocus", ""+searchView.getQuery());
if (0 != searchView.getQuery().length()) {
String spnId = searchView.getQuery().toString();
setSearchResult(spnId);
} else {
setData();
}
return true;
}
#Override
public boolean onQueryTextChange(String newText) {
Log.d("iFocus", ""+newText.toString());
adapter.getFilter().filter(newText);
return true;
}
});
}
All suggestions are welcome. Thanks in advance.

Why don't you use in the overridden method onQueryTextSubmit the parameter that you become to get the query like this:
#Override
public boolean onQueryTextSubmit(String query) {
Log.d("iFocus", query);
if (0 != query.length()) {
setSearchResult(query);
} else {
setData();
}
return true;
}

See my example project with ToolBar and search menu item, min API level = 7:

Setting Background for Actionbar SearchItem

I would like to set the background (something like EditText Background) to my ActionBar SearchItem. That's the current action bar.
I would like to set this background drawable to that.
Here's how I create the searchItem
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.guest_list, menu);
MenuItem searchItem = menu.findItem(R.id.search);
SearchManager searchManager = (SearchManager) getActivity()
.getSystemService(Context.SEARCH_SERVICE);
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB) {
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setSearchableInfo(searchManager
.getSearchableInfo(getActivity().getComponentName()));
searchView.setIconified(true);
searchView.setSubmitButtonEnabled(true);
searchView.setOnQueryTextListener(new OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
setFilter(query);
return false;
}
#Override
public boolean onQueryTextChange(String query) {
setFilter(query);
return false;
}
});
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setSearchableInfo(searchManager
.getSearchableInfo(getActivity().getComponentName()));
searchView.setIconified(true);
searchView.setSubmitButtonEnabled(true);
searchView.setOnQueryTextListener(new OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
setFilter(query);
return false;
}
#Override
public boolean onQueryTextChange(String query) {
setFilter(query);
return false;
}
});
}
}
I've tried setting background by searchView.setBackgroundDrawable but I am not getting what I like to implement.
