I am using the the SearchView in the ActionBar of the ListView. The magnifying glass can be touched, the SearchView shows its edit box, and the user can enter the text for filtering the content of the list. It almost works. However, when the user presses the Up button, the SearchView collapses back to the icon, the text inside the widget is cleared, and the filtering is reset. The effect (in my case) is that the list can be filtered only when the SearchView is not iconified. The wanted behaviour is to keep the filter text also after the SearchView was collapsed.
Attention: The behaviour probably changed in Android 4.3. With 4.2.2 it worked as wanted. See the observations below.
Details: To be more specific, the menu contains the following item:
<item android:id="#+id/menu_search_customers"
android:title="#string/menu_search_text"
android:icon="#android:drawable/ic_menu_search"
android:showAsAction="ifRoom|collapseActionView"
android:actionViewClass="android.widget.SearchView" />
Notice the icon and the android:showAsAction. I belive the Up button appears by default when the SearchView is expanded (by Up I mean the < plus the icon -- see the right image with the blue book from the official Navigation with Back and Up). It seems that the default handler implementation just collapses the expanded SearchView (returns back to the icon state).
When debugging, I have found that the onQueryTextChange() is fired with the empty text when the Up is used. (I believe this was not the case with Android 4.2.2, because it worked as wanted before the OS update.) This is the reason why the filtering of the list items is also reset -- see my onQueryTextChange() below. I want the SearchView collapsed, and the filter text displayed as subtitle in the action bar.
So far, my code related to the SearchView looks like this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// MenuInflater adds the magnifying glass icon for the SearchView
// to the ActionBar as the always visible menu item.
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.customers_menu, menu);
// Get the related SearchView widget.
SearchView sv = (SearchView) menu.findItem(R.id.menu_search_customers)
.getActionView();
// Get the changes immediately.
sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
// I am not sure whether the onQueryTextSubmit() is important
// for the purpose.
#Override
public boolean onQueryTextSubmit(String query) {
getActionBar().setSubtitle(mCurFilter);
return true;
}
#Override
public boolean onQueryTextChange(String newText) {
// The newText is stored into a member variable that
// is used when the new CursorLoader is created.
mCurFilter = newText;
getActionBar().setSubtitle(mCurFilter);
getLoaderManager().restartLoader(0, null,
CustomersOverviewActivity.this);
return true;
}
});
return true;
}
The restarted loader calls the onCreateLoader. Notice the mCurFilter is used for building the SQL query:
#Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
String[] projection = { CustomerTable._ID,
CustomerTable.CODE,
CustomerTable.NAME,
CustomerTable.STREET,
CustomerTable.TOWN };
String selection = null; // init
String[] selectionArgs = null; // init
if ( ! mCurFilter.isEmpty()) {
selection = CustomerTable.NAME + " like ?";
selectionArgs = new String[]{ "%" + mCurFilter +"%" };
}
CursorLoader cursorLoader = new CursorLoader(this,
DemoContentProvider.CUSTOMERS_CONTENT_URI, projection,
selection, selectionArgs,
orderInfo);
return cursorLoader;
}
I would like to detect the situation when the Up is pressed before the onQueryTextChange() is called. This way (say) I could set a flag and block the mCurFilter assignment by the emptied SearchView content. Also, when the search icon is expanded again, I would like to initialize the text in the expanded SearchView from the mCurFilter before it is shown (i.e. the expanded view is preset with the filter text). How that can be done?
Update: The earlier implementation of the SearchView had...
#Override
public void onActionViewCollapsed() {
clearFocus();
updateViewsVisibility(true);
mQueryTextView.setImeOptions(mCollapsedImeOptions);
mExpandedInActionView = false;
}
Now, it contains...
#Override
public void onActionViewCollapsed() {
setQuery("", false);
clearFocus();
updateViewsVisibility(true);
mQueryTextView.setImeOptions(mCollapsedImeOptions);
mExpandedInActionView = false;
}
Do you know what could be the reason for setting the query to the empty string? Should I override the new implementation by the old code? Or is there a better way?
I have written a StatefulSearchView which retains the text:

In demonstration activity:
public class MainActivity extends Activity{

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getActionBar().setHomeButtonEnabled(true);
}
#Override
public boolean onMenuItemSelected(int featureId, MenuItem item) {
if(item.getItemId()==android.R.id.home) {
mSearchView.setIconified(true);
return true;
}
return super.onMenuItemSelected(featureId, item);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
MenuItem item = menu.findItem(R.id.action_search);
mSearchView =(StatefulSearchView)item.getActionView();
mSearchView.setSaveSearchTextState(true);
mSearchView.setOnStatefulQueryTextListener(new OnQueryTextListener(){
#Override
public boolean onQueryTextChange(String newText) {
// TODO Auto-generated method stub
return false;
}
#Override
public boolean onQueryTextSubmit(String query) {
// TODO Auto-generated method stub

In menu xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

android:orderInCategory="100"
android:showAsAction="always"
android:actionViewClass="com.nikola.despotoski.saveablesearchview.StatefulSearchView"
android:title="#string/action_settings"/>
</menu>
In the source of the SearchView, it clearly says that they change the text to "":
#Override
public void onActionViewCollapsed() {
setQuery("", false);
clearFocus();
updateViewsVisibility(true);
mQueryTextView.setImeOptions(mCollapsedImeOptions);
mExpandedInActionView = false;
}
/**
* {#inheritDoc}
*/
#Override
public void onActionViewExpanded() {
if (mExpandedInActionView) return;
mExpandedInActionView = true;
mCollapsedImeOptions = mQueryTextView.getImeOptions();
mQueryTextView.setImeOptions(mCollapsedImeOptions | EditorInfo.IME_FLAG_NO_FULLSCREEN);
mQueryTextView.setText("");
setIconified(false);
}
Let me know if you have issues.
I'm not sure I understand your problem but you can just detect when up is clicked like this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
doSOmething();
return true;
}
return super.onOptionsItemSelected(item);
}
If you intercept the up click, you can presumably do anything you want here. Returning true will consume the event and that should prevent any default action from taking place. This way you can do whatever you want the up button to do while at the same time consuming the up event to prevent clearing of your filters.
I struggle with this a little until I found the solution.
Declare your menuItem like this, check the showAsAction attribute, type only ifRoom, if you set collapseActionView the widget will collapse and show the back button on the actionbar
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/search"
android:actionViewClass="android.widget.SearchView"
android:icon="#drawable/ic_2_action_search"
android:showAsAction="ifRoom"
android:title="#null"/>
</menu>
Set up your SearchView as usual, remember to Add setIconifiedByDefault this will make the icon to start up as an icon
SearchManager searchManager = (SearchManager)getSystemService(Context.SEARCH_SERVICE);
searchView = (SearchView) menu.findItem(R.id.search).getActionView();
searchView.setIconifiedByDefault(true);
searchView.setOnQueryTextListener(new SearchViewOnQueryListener());
searchView.setOnCloseListener(new SearchViewOnCloseListener());
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
On your QueryListener is where you handle the end of your search like so, here is where you use onActionViewCollapse() which collapse back the ViewSearch
#Override
public boolean onQueryTextSubmit(String query) {
makeSearchRequest(SEARCH_TYPE_KEYWORD, query);
searchView.setQuery("", false);
searchView.clearFocus();
searchView.onActionViewCollapsed();
buttonClearSearchResults.setVisibility(View.VISIBLE);
return false;
}

I have just implemented the "android.support.v7.widget.SearchView" in my Actionbar to search for some pdf files.
When i insert multiple characters for search, the list of suggestions is shown perferctly. But when i'm only entering one single character, there are no proposals shown, although the function to populate the suggestions is called.
Do you have an idea how to change that behavior, to get the proposals shown when entering only one character?
This is where i simply define the searchview inside a menu.
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/pdf_menu_search_item"
android:icon="#mipmap/ic_search_white_24dp"
android:title="Suche"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always"/></menu>
In my Activity, the following code is implemented:
private static final String[] SUGGESTIONS = {
"Amsterdam","Berlin","Rome"
};
private SimpleCursorAdapter mAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
#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_contextual_actionbar, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
return super.onOptionsItemSelected(item);
}
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
final SearchView mSearchView;
mSearchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.pdf_menu_search_item));
final String[] from = new String[] {"cityName"};
final int[] to = new int[] {android.R.id.text1};
mAdapter = new SimpleCursorAdapter(Startseite.this,
android.R.layout.simple_list_item_1,
null,
from,
to,
CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);
mSearchView.setSuggestionsAdapter(mAdapter);
mSearchView.setOnSuggestionListener(new SearchView.OnSuggestionListener() {
#Override
public boolean onSuggestionClick(int position) {
return true;
}
#Override
public boolean onSuggestionSelect(int position) {
return true;
}
});
mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
populateAdapter(newText);
return true;
}
});
return super.onPrepareOptionsMenu(menu);
}
// You must implements your logic to get data using OrmLite
private void populateAdapter(String query) {
final MatrixCursor c = new MatrixCursor(new String[]{ BaseColumns._ID, "cityName" });
for (int i=0; i<SUGGESTIONS.length; i++) {
if (SUGGESTIONS[i].toLowerCase().startsWith(query.toLowerCase()))
{ c.addRow(new Object[] {i, SUGGESTIONS[i]}); }
}
mAdapter.changeCursor(c);
mAdapter.notifyDataSetChanged();
}
Working with more than one characters:
Not working with only one character:
Please has anyone an idea how to fix that?
I have just found the answer.
If you are using AppCompatActivity (like me), you can set the searchview threshold like that:
AutoCompleteTextView searchAutoCompleteTextView = (AutoCompleteTextView) mSearchView.findViewById(getResources().getIdentifier("search_src_text", "id", getPackageName()));
searchAutoCompleteTextView.setThreshold(1);
Now the search-suggestions will be shown from the first character on.
Maybe it is helpful for others :)
I have a search action item associated with an AppCompatActivity. The search icon appears but when I click on it, it doesn't show the edit control allowing me to put in the search text. I've tried all the obvious issues but I just can't seem to get this to work.
This app loads a PDF a switches out the Toolbar based on user choices. The first toolbar shows a search item. Once this is selected it adds the searchNext and searchPrev buttons. All this worked until I switched to Material Design. I think the problem has something to do with replacing the menu but I'm not sure.
Here is the manifest:

EDIT
One item of note: the call get getActionView on the search item is returning null. I think this might have something to do with the problem. I then try and force it but I'm not sure that's right either. Here is the code in question:
protected ActionMode mActionModeSearch;
private ActionMode.Callback mActionModeSearchCallback = new ActionMode.Callback()
{
#Override
public boolean onCreateActionMode(ActionMode actionMode, Menu menu)
{
actionMode.getMenuInflater().inflate(R.menu.pdf_menu_search, menu);
mSearchMenuPrev = (MenuItem) menu.findItem(R.id.pdf_menu_search_prev);
mSearchMenuPrev.setEnabled(false);
mSearchMenuNext = (MenuItem) menu.findItem(R.id.pdf_menu_search_next);
mSearchMenuNext.setEnabled(false);
mSearchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.pdf_menu_search_item));
// TODO this search functionality still isn't working
MenuItem searchItem = menu.findItem(R.id.pdf_menu_search_item);
mSearchView=(SearchView)MenuItemCompat.getActionView(searchItem); // ALWAYS COMES BACK AS NULL
if(mSearchView==null)
{
//MenuItemCompat.setShowAsAction(searchItem,MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW|MenuItem.SHOW_AS_ACTION_ALWAYS);
MenuItemCompat.setShowAsAction(searchItem, MenuItem.SHOW_AS_ACTION_ALWAYS);
mSearchView = new SearchView(MuPDFActivity.this);
MenuItemCompat.setActionView(searchItem, mSearchView);
}
if(mSearchView != null)
{
mSearchView.setIconifiedByDefault(false);
mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener()
{
#Override
public boolean onQueryTextSubmit(String s)
{
return false;
}
#Override
public boolean onQueryTextChange(String s)
{
mSearchString = s;
if(s.length() > 0)
{
mSearchMenuPrev.setEnabled(true);
mSearchMenuNext.setEnabled(true);
}
// Remove any previous search results
if (SearchTaskResult.get() != null && !mSearchString.equals(SearchTaskResult.get().txt))
{
SearchTaskResult.set(null);
mDocView.resetupChildren();
}
return false;
}
});
searchModeOn();
}
return true;
}
#Override
public boolean onPrepareActionMode(ActionMode actionMode, Menu menu)
{
return false;
}
#Override
public boolean onActionItemClicked(ActionMode actionMode, MenuItem menuItem)
{
switch(menuItem.getItemId())
{
case R.id.pdf_menu_search_prev:
mSearchView.clearFocus();
hideKeyboard();
search(-1);
return true;
case R.id.pdf_menu_search_next:
mSearchView.clearFocus();
hideKeyboard();

return true;

return false;

}
#Override

{

mActionModeSearch = null;
resetHideToolbarsTimer();
}
};
EDIT 2:
I got the control to come up but now the "next" and "prev" menu items are gone. Also, the control is not left aligned. And, I still have to expand the search control.
Screenshot:
Here is the updated code that got me here:
public boolean onCreateActionMode(ActionMode actionMode, Menu menu)
{
actionMode.getMenuInflater().inflate(R.menu.pdf_menu_search, menu);
mSearchMenuPrev = menu.findItem(R.id.pdf_menu_search_prev);
mSearchMenuPrev.setEnabled(false);
mSearchMenuNext = menu.findItem(R.id.pdf_menu_search_next);
mSearchMenuNext.setEnabled(false);
MenuItem searchItem = menu.findItem(R.id.pdf_menu_search_item);
MenuItemCompat.setShowAsAction(searchItem, MenuItem.SHOW_AS_ACTION_ALWAYS);
mSearchView = new SearchView(MuPDFActivity.this);
MenuItemCompat.setActionView(searchItem, mSearchView);
//mSearchView.setIconifiedByDefault(false);
mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener()
{
#Override
public boolean onQueryTextSubmit(String s)
{
return false;
}
#Override
public boolean onQueryTextChange(String s)
{
mSearchString = s;
if(s.length() > 0)
{
mSearchMenuPrev.setEnabled(true);
mSearchMenuNext.setEnabled(true);
}
// Remove any previous search results
if (SearchTaskResult.get() != null && !mSearchString.equals(SearchTaskResult.get().txt))
{
SearchTaskResult.set(null);
mDocView.resetupChildren();
}
return false;
}
});
searchModeOn();
return true;
}
If I call mSearchView.setIconified(false), I get the following screenshots. The menu items are all there but they are in overflow. If I expand overflow, I see the search menu but when I click on it, it goes back to my original problem of no edit box to enter search string. In other words, it looks like the first screenshot below when I click on "Search":
I finally had to build it manually. I changed the menu xml file to:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<group android:id="#+id/group_search_mode">
<item
android:id="#+id/pdf_menu_search_item"
android:title="#string/search"
android:icon="#drawable/ic_pdf_action_search"
app:showAsAction="ifRoom"
app:actionViewClass="android.support.v7.widget.SearchView"/>
</group>
I then changed the code in the ActionMode.Callback to manually build the menu and force the search control open. I think it might be overkill but it works:
private static final int PREV_MENU_ITEM_ID = 1;
private static final int NEXT_MENU_ITEM_ID = 2;
protected ActionMode mActionModeSearch;
private ActionMode.Callback mActionModeSearchCallback = new ActionMode.Callback()
{
#Override
public boolean onCreateActionMode(ActionMode actionMode, Menu menu)
{
actionMode.getMenuInflater().inflate(R.menu.pdf_menu_search, menu);
// Load search action
MenuItem searchItem = menu.findItem(R.id.pdf_menu_search_item);
MenuItemCompat.setShowAsAction(searchItem, MenuItem.SHOW_AS_ACTION_ALWAYS);
mSearchView = new SearchView(MuPDFActivity.this);
MenuItemCompat.setActionView(searchItem, mSearchView);
MenuItemCompat.expandActionView(searchItem);
mSearchView.setIconifiedByDefault(false);
mSearchView.setIconified(false);
// Load prev and next menu items
mSearchMenuPrev = menu.add(0, PREV_MENU_ITEM_ID, 1, R.string.search_prev);
mSearchMenuPrev.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
mSearchMenuPrev.setEnabled(false);
mSearchMenuNext = menu.add(0, NEXT_MENU_ITEM_ID, 1, R.string.search_next);
mSearchMenuNext.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
mSearchMenuNext.setEnabled(false);
mSearchView.setOnQueryTextListener(new SearchView.OnQueryTextListener()
{
#Override
public boolean onQueryTextSubmit(String s)
{
search(1);
return false;
}
#Override
public boolean onQueryTextChange(String s)
{
mSearchString = s;
if(s.length() > 0)
{
mSearchMenuPrev.setEnabled(true);
mSearchMenuNext.setEnabled(true);
}
// Remove any previous search results
if (SearchTaskResult.get() != null && !mSearchString.equals(SearchTaskResult.get().txt))
{
SearchTaskResult.set(null);
mDocView.resetupChildren();
}
return false;
}
});
searchModeOn();
return true;
}
#Override
public boolean onPrepareActionMode(ActionMode actionMode, Menu menu)
{
return false;
}
#Override
public boolean onActionItemClicked(ActionMode actionMode, MenuItem menuItem)
{
switch(menuItem.getItemId())
{
case PREV_MENU_ITEM_ID:
mSearchView.clearFocus();
hideKeyboard();
search(-1);
return true;
case NEXT_MENU_ITEM_ID:

hideKeyboard();
search(1);

I hope this helps someone out there. What a pain!
When using search view, I have a requirement from customer that they want to retain the search content after reopen the search view. My Search view is on a list view and do a real timing filtering based on what user input into the search box. When closed the search box by either click the back button on the phone or click the soft back button on the top left on action bar, the search box closed, search view iconfied. But when reopen it next time, the search query used last time is also been cleared, which I do not want.
My question is that is there a way I can keep the search view content there. Just hiding the search box, but not clear the content?
My related code are as follow:
MenuItem search;
SearchView searchView;
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_locationlist_fragment, menu);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
search = menu.findItem(R.id.action_search_location_list);
searchView = (SearchView) MenuItemCompat.getActionView(search);
SearchManager searchManager = (SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);
searchView.setSearchableInfo(searchManager.getSearchableInfo(getActivity().getComponentName()));
searchView.setIconifiedByDefault(false);
searchView.setOnQueryTextListener(this);
searchView.setOnQueryTextFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
//This will make sure, when user closed search view, the list will be restored.
if(!hasFocus) {
Log.i(Tags.LOCATIONLIST,"Search Close");
search.collapseActionView();
} else {
}
}
}
});
ImageView closeButton = (ImageView)searchView.findViewById(R.id.search_close_btn);
closeButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
EditText searchEditText = (EditText)searchView.findViewById(R.id.search_src_text);
searchEditText.setText("");
if (((LocationListAdapter)locationListView.getAdapter())!=null) {
((LocationListAdapter) locationListView.getAdapter()).getFilter().filter("");
}
}
});
}
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_search_location_list:
((BaseActivity) getActivity()).onSearchRequested();
return true;
case R.id.action_refresh_location_list:
refreshLocationList();
return true;
default:
return false;
}
}
#Override
public boolean onQueryTextSubmit(String s) {
return false;
}
#Override
public boolean onQueryTextChange(String s) {
if (((LocationListAdapter)locationListView.getAdapter())!=null) {
if (TextUtils.isEmpty(s)) {
locationListView.clearTextFilter();
} else {
((LocationListAdapter) locationListView.getAdapter()).getFilter().filter(s);
//locationListView.setFilterText(s.toString());
}
}
return true;
}
Use
SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
searchView.setIconified(false);
Any query text is cleared when iconified. So setIconified to false. And i have used android.widget.SearchView
Save your String in a variable (e.g. myWantedString) and
override setOnClickListener that trigers everytime you open the SearchView and use setQuery. Your code should be:
searchView.setOnSearchClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
searchView.setQuery(myWantedString, false);
}
});
To save your string each time the SearchView closes implement setOnCloseListener and override onClose():
searchView.setOnCloseListener(new SearchView.OnCloseListener()
{
#Override
public boolean onClose()
{
myWantedString = searchView.getQuery();
return false;
}
});
searchView.setQuery() works if was called with a delay after menu item expansion.
MenuItemCompat.setOnActionExpandListener(searchItem, new MenuItemCompat.OnActionExpandListener() {
#Override
public boolean onMenuItemActionExpand(MenuItem item) {
final SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
// set query text with a delay
searchView.post(new Runnable() {
#Override
public void run() {
searchView.setQuery(query, false);
}
});
return true;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem item) {
return true;
}
});
You can create an Activity which can be called when the user searches and the search result can be stored in the Bundle during the callback method onPause or onSaveInstanceState , when the Activity is called once again restore it from the bundle.
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setIconified(false);
searchView.setOnSearchClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
searchView.setQuery("SEARCH_WORD", false);
}
});
https://developer.android.com/reference/android/widget/SearchView
Sets a listener to inform when the search button is pressed. This is only relevant when the text field is not visible by default. Calling setIconified(false) can also cause this listener to be informed.
Background
I have a searchView being initialized using a special class I've made, that's being used across all of the activities and fragments.
The problem
Recently, probably due to updates to the support library (or because I didn't use it so far, I don't remember), I can't catch events of expand/collapse of the searchView.
As I've found, this happens even if I use setSupportActionBar with a Toolbar instance.
What I've tried
I've tried using each of the next methods, but none worked:
MenuItemCompat.setOnActionExpandListener.
MenuItemCompat.setOnActionExpandListener together with iconifying the SearchView, as suggested on some websites.
setOnActionExpandListener on the search menu item itself, but then it crashes since it can't be used when extending the ActionBarActivity.
SearchView.setOnCloseListener , but this works only if I close it, and only using the UI (doesn't get called when calling collapseActionView ).
I've also tried to mess around with the XML file of the search menu item.
The code
Here's the helper class I've made:
SearchHolderCompat
public class SearchHolderCompat {
public MenuItem mSearchMenuItem;
public SearchView mSearchView;
private final Activity _context;
public SearchHolderCompat(final Activity context) {
_context = context;
}
public boolean isCurrentyExpanded() {
return mSearchMenuItem != null && MenuItemCompat.isActionViewExpanded(mSearchMenuItem);
}
public boolean hasQuery() {
return mSearchMenuItem != null && mSearchView != null && MenuItemCompat.isActionViewExpanded(mSearchMenuItem)
&& !TextUtils.isEmpty(mSearchView.getQuery());
}
public void addSearchItemAndInit(final Menu menu, final OnQueryTextListener onQueryTextListener,
final OnActionExpandListener onActionExpandListener) {
final MenuInflater menuInflater = _context.getMenuInflater();
menuInflater.inflate(R.menu.search_menu_item, menu);
init(menu.findItem(R.id.menuItem_search), onQueryTextListener, onActionExpandListener);
}
public void init(final MenuItem searchMenuItem, final OnQueryTextListener onQueryTextListener,
final OnActionExpandListener onActionExpandListener) {
this.mSearchMenuItem = searchMenuItem;
mSearchView = (SearchView) MenuItemCompat.getActionView(searchMenuItem);
if (mSearchView == null) {
MenuItemCompat.setShowAsAction(searchMenuItem, MenuItemCompat.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW
| MenuItemCompat.SHOW_AS_ACTION_ALWAYS);
MenuItemCompat.setActionView(searchMenuItem, mSearchView = new SearchView(_context));
}
mSearchView.setQueryHint(_context.getString(R.string.search));
mSearchView.setOnQueryTextListener(onQueryTextListener);
MenuItemCompat.setOnActionExpandListener(searchMenuItem, onActionExpandListener);
}
}
MainActivity.java
public class MainActivity extends ActionBarActivity {
SearchHolderCompat mSearchHolder = new SearchHolderCompat(this);
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(final Menu menu) {
mSearchHolder.addSearchItemAndInit(menu, new OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(final String arg0) {
android.util.Log.d("AppLog", "onQueryTextSubmit");
return false;
}
#Override

return true;
}
}, new OnActionExpandListener() {
#Override

android.util.Log.d("AppLog", "onMenuItemActionExpand");
return false;
}
#Override
public boolean onMenuItemActionCollapse(final MenuItem arg0) {
android.util.Log.d("AppLog", "onMenuItemActionCollapse");
return false;
}
});
return true;
}
}

</menu>
The question
What's the correct way to handle the SearchView and the search menu item (using the support library) ?
How come "MenuItemCompat.setOnActionExpandListener" doesn't work?
After looking for a solution for couple of hours I've implement something like this. and worked for me. (I wanted Expand and Collapse events anyhow)
.
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
getMenuInflater().inflate(R.menu.menu_main, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
if(searchItem != null)
{
SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
// use this method for search process
searchView.setOnSearchClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
//Search view is expanded
showSearchPage();
}
});
searchView.setOnCloseListener(new SearchView.OnCloseListener()
{
#Override
public boolean onClose()
{
//Search View is collapsed
hideSearchPage();
return false;
}
});
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener()
{
#Override
public boolean onQueryTextSubmit(String query)
{
// use this method when query submitted
Toast.makeText(MainActivity.this, query, Toast.LENGTH_SHORT).show();
return false;
}
#Override
public boolean onQueryTextChange(String newText)
{
// use this method for auto complete search process
Log.e("SearchValueIs",":"+newText);
return false;
}
});
}
return super.onCreateOptionsMenu(menu);
}
Hope It will help Someone...
Android training
app:showAsAction="ifRoom|collapseActionView"
You can add ViewTreeObserver to track the visibility state of android.support.v7.appcompat.R.id.search_edit_frame. You can check my answer here: https://stackoverflow.com/a/28762632/1633609
You can see below how to handle Expand and Collapsed states!
To answer why MenuItemCompat.setOnActionExpandListener(...) is not working, this listener is only called if the showAsAction of the SearchView is set to MenuItemCompat.SHOW_AS_ACTION_ALWAYS (you can also add more options).
This is the copy of my answer form the other question:
I found that MenuItemCompat.setOnActionExpandListener(...) is not working if you don't pass:
searchItem
.setShowAsAction(MenuItemCompat.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW
| MenuItemCompat.SHOW_AS_ACTION_ALWAYS);
But this is changing the SearchView and is replacing the DrawerToggle with back arrow.
I wanted to keep the original views and still track the Expanded/Collapsed state and use supported Search View.
Solution:
When android.support.v7.widget.SearchView is changing the view state the LinearLayout view's, with id android.support.v7.appcompat.R.id.search_edit_frame, visibility value is being changed from View.VISIBLE to View.GONE and opposite. So I add ViewTreeObserver to track the visibility change of the search edit frame.
menu_search.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto" >
<item
android:id="#+id/action_search"
android:icon="#android:drawable/ic_menu_search"
android:title="#string/search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always"/>
</menu>
In the activity:
import android.support.v4.view.MenuItemCompat;
import android.support.v7.widget.SearchView;
import android.view.Menu;
import android.view.MenuItem;
..........
private View mSearchEditFrame;
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_search, menu);
MenuItem searchItem = (MenuItem) menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat
.getActionView(searchItem);
searchView.setSubmitButtonEnabled(false);
mSearchEditFrame = searchView
.findViewById(android.support.v7.appcompat.R.id.search_edit_frame);
ViewTreeObserver vto = mSearchEditFrame.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
int oldVisibility = -1;
#Override
public void onGlobalLayout() {
int currentVisibility = mSearchEditFrame.getVisibility();
if (currentVisibility != oldVisibility) {
if (currentVisibility == View.VISIBLE) {
Log.v(TAG, "EXPANDED");
} else {
Log.v(TAG, "COLLAPSED");
}
oldVisibility = currentVisibility;
}
}
});
return super.onCreateOptionsMenu(menu);
}
I know I'm very late to post this answer but hope it helps someone else. I recently came across the issue and I just made the Override methods return true and it worked like a charm.
#Override
public boolean onMenuItemActionExpand(final MenuItem arg0) {
android.util.Log.d("AppLog", "onMenuItemActionExpand");
return true;
}
#Override
public boolean onMenuItemActionCollapse(final MenuItem arg0) {
android.util.Log.d("AppLog", "onMenuItemActionCollapse");
return true;
}
In more recent versions
menuSearch.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
#Override
public boolean onMenuItemActionExpand(MenuItem item) {
//SearchView appers
return true;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem item) {
//SearchView disappears
return true;
}
});
I tried to get Search box to work on Action Bar Sherlock.
This is my PreLocationActivity:
#ContentView(R.layout.search)
public class PreLocationActivity extends RoboSherlockActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.map_layout);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
//Used to put dark icons on light action bar
menu.add("Search")
.setIcon(R.drawable.ic_search_inverse)
.setActionView(R.layout.collapsible_edittext)
.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
return true;
}
#Override
public boolean onSearchRequested() {
return super.onSearchRequested();
}
}
This is my SearchableActivity:
#ContentView(R.layout.search)
public class SearchableActivity extends RoboSherlockFragmentActivity {
#InjectView(R.id.addressListView) ListView addressView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the intent, verify the action and get the query
Intent intent = getIntent();
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
doGeoSearch(query);
}
}
public void doGeoSearch(String query){
Geocoder geocoder;
ArrayList<Address> addresses;
ArrayList<String> address = new ArrayList<String>() ;
geocoder = new Geocoder(this, Locale.getDefault());
try {
addresses = (ArrayList<Address>) geocoder.getFromLocationName(query, 6);
Log.d("Address",String.valueOf(addresses));
for(int i = 0;i<addresses.size();i++)
{
String addr = new String();
addr.concat(addresses.get(i).getAddressLine(0));
addr.concat(addresses.get(i).getAddressLine(1));
addr = addresses.get(i).getAddressLine(0) + addresses.get(i).getLocality() + addresses.get(i).getAdminArea();
//addr.concat(addresses.get(i).getAddressLine(2));
Log.d("addr",addr);
address.add(addr);
}
SearchAddressAdapater addressList = new SearchAddressAdapater(getApplicationContext(),R.layout.search_list,addresses, SearchableActivity.this);
addressView.setAdapter(addressList);
//ListView addressListView = new ListView();
} catch (IOException e) {
//Handle exception
}
}
No success at all. As in, when I type something on the Prelocation Activity and press enter, nothing is being searched. Do I have to treat it as an EditText and write a text listener for that which then calls the geoCoder and gets me the locations or is there a smarter way to go about it?
Android Support Library(v4 + v7):
Support Library v7: http://developer.android.com/tools/support-library/features.html#v7-appcompat
Google now supports the ActionBar compatibility back to Android 2.1(API 7).
It is easy to make the transition because the method names are the same and/or very similar.
Add the Support Library with Resources: http://developer.android.com/tools/support-library/setup.html#libs-with-res
Your Manifest: AndroidManifest.xml
<uses-sdk
android:minSdkVersion="7"
android:targetSdkVersion="17" />
Your Menu: menu.xml
<item
android:id="#+id/menu_search"
android:actionViewClass="android.support.v7.widget.SearchView"
android:icon="#drawable/ic_action_search"
android:showAsAction="ifRoom|collapseActionView"
android:title="Search"/>
ActionBarSherlock [deprecated, use appcompat]:
Here is how to use the standard SearchView and SearchManager in Android with ActionBarSherlock! I am using this code and works fine. I have tested this on Android 2.3(API 10) - Android 4.3(API 18).
Great Tutorial and Documentation:
http://developer.samsung.com/android/technical-docs/UI-unification-with-older-Android-versions-using-ActionBarSherlock
Keep in mind:
Custom Search with ActionBarSherlock(min. API 7)
SearchView with ActionBarSherlock(min. API 8)
Your Menu: menu.xml
<item
android:id="#+id/menu_search"
android:actionViewClass="com.actionbarsherlock.widget.SearchView"
android:icon="#drawable/ic_action_search"
android:showAsAction="ifRoom|collapseActionView"
android:title="Search"/>
For Both:
Your Activity: MainActivity.java
public boolean onCreateOptionsMenu(Menu menu)
{
getSupportMenuInflater().inflate(R.menu.menu, menu);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) menu.findItem(R.id.menu_search).getActionView();
if (null != searchView )
{
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);
}
SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener()
{
public boolean onQueryTextChange(String newText)
{
// this is your adapter that will be filtered
adapter.getFilter().filter(newText);
return true;
}
public boolean onQueryTextSubmit(String query)
{
// this is your adapter that will be filtered
adapter.getFilter().filter(query);
return true;
}
};
searchView.setOnQueryTextListener(queryTextListener);
return super.onCreateOptionsMenu(menu);
}
Let me know if this works for you as well and let me know if you need anymore help!
private EditText search;
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu)
{
menu.add(0, 1, 1, R.string.menu_search).setIcon(R.drawable.ic_action_search).setActionView(R.layout.action_search).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_COLLAPSE_ACTION_VIEW);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item)
{
switch (item.getItemId())
{
case 1:
search = (EditText) item.getActionView();
search.addTextChangedListener(filterTextWatcher);
search.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}
}
private TextWatcher filterTextWatcher = new TextWatcher()
{
public void afterTextChanged(Editable s)
{
}
public void beforeTextChanged(CharSequence s, int start, int count, int after)
{
}
public void onTextChanged(CharSequence s, int start, int before, int count)
{
// your search logic here
}
};
A similar question there are here where I had the problem to assign the adapter.
How to implement search widget with a listview using SherlockActionbar?
I hope that it would help because I had the same problem.
To use the adapter the best way is that the class implements SearchView.OnQueryTextListener and then you don´t have to create the inner class and you will have the adapter.
In your code will be something as:
public class MainActivity extends SherlockListActivity implements SearchView.OnQueryTextListener
and then in the class you have to define the methods. The adapter will be the adapter that you have in your class ArrayAdapter adapter. But you should define it as private in the class.
public boolean onQueryTextChange(String newText) {
// this is your adapter that will be filtered
adapter.getFilter().filter(newText);
return true;
}
public boolean onQueryTextSubmit(String query) {
// this is your adapter that will be filtered
adapter.getFilter().filter(query);
return true;
}
In the line where you are setting:
searchView.setOnQueryTextListener(queryTextListener);
Should be:
searchView.setOnQueryTextListener(this);
If you have any problem let me know, I was with a similar problem today and read your question without answer.
