I am getting Nullpointerexception when trying to add SearchView to my appcompat activity.I have already gone through this answer but couldn't resolve it.
Here is my
menu_main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">
<item android:id="#+id/action_search"
android:icon="#android:drawable/ic_menu_search"
android:title="Search"
android:iconifiedByDefault="false"
app:showAsAction="always"
app:actionViewClass="android.support.v7.widget.SearchView"/>
onCreateOptionsMenu
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
getMenuInflater().inflate(R.menu.menu_main, menu);
mSearchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_search));
mSearchView.setIconifiedByDefault(true);
I also tried:
mSearchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
Getting Below exception:
java.lang.NullPointerException: Attempt to invoke virtual method
'void
android.support.v7.widget.SearchView.setIconifiedByDefault(boolean)'
on a null object reference
Try this code:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
getMenuInflater().inflate(R.menu.menu_main, menu);
searchView = new SearchView(this.getSupportActionBar().getThemedContext());
searchView.setSearchableInfo(searchManager.
getSearchableInfo(getComponentName()));
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
// collapse the view ?
//menu.findItem(R.id.menu_search).collapseActionView();
Log.e("queryText",query);
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
// search goes here !!
// listAdapter.getFilter().filter(query);
Log.e("queryText",newText);
return false;
}
});
}
Try this. It is Working
menu.xml
<item
android:id="#+id/action_search"
android:icon="#android:drawable/ic_menu_search"
android:iconifiedByDefault="false"
android:title="Search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always" />
Java Code:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.sol_menu, menu);
MenuItem menuItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) menuItem.getActionView();
searchView.setIconified(false);
super.onCreateOptionsMenu(menu);
}

onOptionsItemSelected(item: MenuItem) is not called for a tap on a menu item with app:actionProviderClass in a project with AndroidX.
Any idea why?
<item
android:id="#+id/open_map"
android:orderInCategory="100"
android:title="#string/map"
app:showAsAction="always"/>
<item
android:id="#+id/add_player"
android:orderInCategory="100"
android:title="#string/add_player"
android:icon="#drawable/ic_add_white_24dp"
app:showAsAction="ifRoom"/>
<item
android:id="#+id/share"
android:orderInCategory="100"
android:title="#string/share"
app:actionProviderClass="androidx.appcompat.widget.ShareActionProvider"
app:showAsAction="ifRoom"/>
You used app:actionProviderClass="androidx.appcompat.widget.ShareActionProvider"
Use this same as search action view
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.example, menu);
this.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.search).getActionView();
search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));
search.setOnQueryTextListener(new OnQueryTextListener() {
#Override
public boolean onQueryTextChange(String query) {
loadHistory(query);
return true;
}
});
}
return true;
}
I am using Search view in the toolbar. I am facing issue with the close icon.
It is working as excepted on mobile but not working on Android tablets. On the tablet, it is showing in the middle of the action bar instead of right side.
As shown in below images:
On Mobile (Correct):
On Tablet (Incorrect):
My XML Code:
<?xml version="1.0" encoding="utf-8"?>

app:showAsAction="collapseActionView|ifRoom"
android:icon="#mipmap/ic_search_white_24dp"
android:title="Search" />
</menu>
My JAVA Code:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
menu.clear();
inflater.inflate(R.menu.menu_search_view_explore_ideas, menu);
SearchManager searchManager =
(SearchManager) getActivity().getSystemService(Context.SEARCH_SERVICE);
searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
searchView.setQueryHint("Search...");
((EditText) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text)).setTextColor(Color.WHITE);
((EditText) searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text)).setHintTextColor(getResources().getColor(R.color.notify_user_color));
if (searchManager != null) {
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getActivity().getComponentName()));
}
AutoCompleteTextView searchTextView = searchView.findViewById(android.support.v7.appcompat.R.id.search_src_text);
try {
Field mCursorDrawableRes = TextView.class.getDeclaredField("mCursorDrawableRes");
mCursorDrawableRes.setAccessible(true);
mCursorDrawableRes.set(searchTextView, R.drawable.cursor_for_search_view); //This sets the cursor resource ID to 0 or #null which will make it visible on white background
} catch (Exception e) {
}
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
mAdapter.getFilter().filter(query);
return true;
}
#Override
public boolean onQueryTextChange(String newText) {
mAdapter.getFilter().filter(newText);
return true;
}
});
}
Let me know if I am missing something.
you try like this in your onCreateOptionsMenu
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_search_view_explore_ideas, menu);
SearchView searchView = (SearchView)menu.findItem(R.id.action_search).getActionView();
searchView.setMaxWidth(Integer.MAX_VALUE);
In your onCreateOptionsMenu() try this for searchView after inflating menu,
searchView.setMaxWidth(Integer.MAX_VALUE);
In your onCreateOptionsMenu()
try following code for searchView after inflating menu,
SearchView searchView= (SearchView)menu.findItem(R.id.action_search).getActionView();
searchView.setMaxWidth(Integer.MAX_VALUE);
Try this on onCreateOptionsMenu
searchView.setMaxWidth(Integer.MAX_VALUE);
In your OnCreateView
make following change
final SearchView searchView = (SearchView) menuItem.getActionView();
searchView.setMaxWidth(Integer.MAX_VALUE);
I am working on the following screen:
1 Screenshot
Here on the toolbar ,i am having a search icon.To add this search icon ,i have used the following code:
menu_friend_list_activity.xml
<?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">
<item
android:id="#+id/action_search"
android:icon="#drawable/search"
android:orderInCategory="100"
android:title="#string/action_search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="always" />
</menu>
Code inside Activity
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.menu_friend_list_activity, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_search:
Toast.makeText(getApplicationContext(), "Search button clicked", Toast.LENGTH_SHORT).show();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
On clicking search icon i want to display the SearchView in toolbar(if i am not wrong here).In short i want to implement the following screen:
Please tell me how can i implement this.Search will be different for different fragments.
try this
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.search_actions, menu);
MenuItem searchViewItem = menu.findItem(R.id.action_search);
// Get the SearchView and set the searchable configuration
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) searchViewItem.getActionView();
searchView.setQueryHint("Search for Product,Brands...");
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);// Do not iconify the widget; expand it by defaul
SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
public boolean onQueryTextChange(String newText) {
// This is your adapter that will be filtered
Toast.makeText(getApplicationContext(),"textChanged :"+newText,Toast.LENGTH_LONG).show();
return true;
}
public boolean onQueryTextSubmit(String query) {
// **Here you can get the value "query" which is entered in the search box.**
Toast.makeText(getApplicationContext(),"searchvalue :"+query,Toast.LENGTH_LONG).show();
return true;
}
};
searchView.setOnQueryTextListener(queryTextListener);
return true;
}
Your not inflating the menu correctly, Here is how your supposed to inflate it to get the screen you want
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.yourmenyxml, menu);
item = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
I had similar issue. and I solved as following:
MenuItem searchItem = menu.findItem(R.id.ot_action_search);
final SearchView searchView = (SearchView) searchItem.getActionView();
searchItem.expandActionView();
searchView.setIconified(false);
searchView.setQuery(searchQuery, false);
NB: the expandActionView() should be invoked on searchItem menu item not on the searchView. that was my mistake.
I used SherlockActionBar for my ActionBar, but I want to use AppCompact for my search view. To change my code from sherlock to AppCompact, I wrote this:
#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_main, menu);
// SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_search));
//searchView.setOnQueryTextListener(this);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String s) {
return false;
}
#Override
public boolean onQueryTextChange(String s) {
return false;
}
});
return true;
// return super.onCreateOptionsMenu(menu);
}
xml menu:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity">
<item
android:id="#+id/action_search"
android:actionViewClass="android.support.v7.widget.SearchView"
android:icon="#android:drawable/ic_menu_search"
android:title="action_search"
app:showAsAction="always|collapseActionView" />
</menu>
but it crashed. How can I fix it?
EDIT:
change android:actionViewClass to app:actionViewClass
I'm trying to listen to text changes in my SearchView from a Fragment but it fails on this line: menu.findItem(R.id.action_search);
Exception:
java.lang.ClassCastException: android.support.v7.internal.view.menu.MenuItemWrapperJB cannot be cast to android.support.v7.widget.SearchView
at se.xxx.xxx.FragmentList.onCreateOptionsMenu(FragmentList.java:155)
My onCreateOptionsMenu (in Fragment):
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.main, menu);
SearchView sv = (SearchView) menu.findItem(R.id.action_search); //crashes here
sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String s) {
return false;
}
#Override
public boolean onQueryTextChange(String s) {
adapter.getFilter().filter(s.toString());
return false;
}
});
}
menu layout xml (main.xml):
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="se.xxx.xxx.MainActivity" >
<item
app:actionViewClass="android.support.v7.widget.SearchView"
android:id="#+id/action_search"
android:icon="#android:drawable/ic_menu_search"
android:title="blabla"
app:showAsAction="always"
/>
Right way to cast SearchView in AppCompat library:
MenuItem menuItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) MenuItemCompat.getActionView(menuItem);
