menu.findItem returns null

android, android-layout, searchview

Solution

finally i found the problem:

I changed the last line in my /res/menu/sales.xml from:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto" >
<!-- Search Widget -->
<item android:id="@+id/search_view_productos"
    android:title="@string/action_search"
    android:icon="@drawable/ic_action_search"
    app:showAsAction="always|collapseActionView"
    android:actionViewClass="android.widget.SearchView" />
</menu>

to this:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto" >
<!-- Search Widget -->
<item android:id="@+id/search_view_productos"
    android:title="@string/action_search"
    android:icon="@drawable/ic_action_search"
    app:showAsAction="always|collapseActionView"
    app:actionViewClass="android.widget.SearchView" />
</menu>

Problem was the xml namespace on actionViewClass

Problem

I can't find the solution please help The implements: ``` public class VentasActivity extends ActionBarActivity implements NavigationDrawerFragment.NavigationDrawerCallbacks, android.support.v7.widget.SearchView.OnQueryTextListener ``` where returns null: ``` @Override public boolean onCreateOptionsMenu(Menu menu) { if (!mNavigationDrawerFragment.isDrawerOpen()) { getMenuInflater().inflate(R.menu.sales, menu); restoreActionBar(); // HERE RETURNS NULL searchView = (SearchView) menu.findItem(R.id.action_product_search).getActionView(); if (searchView != null) { final Menu menu_block = menu; searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() { @Override public boolean onQueryTextSubmit(String query) { // collapse the view ? menu_block.findItem(R.id.action_product_search).collapseActionView(); return false; } @Override public boolean onQueryTextChange(String newText) { // search goes here !! // listAdapter.getFilter().filter(query); return false; } }); Log.i("sales module", "SearchView OK"); } else Log.i("sales module", "SearchView is null"); return true; } return super.onCreateOptionsMenu(menu); } ``` and sales.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_product_search" android:title="@string/action_search" android:icon="@drawable/ic_action_search" app:showAsAction="always|collapseActionView" android:actionViewClass="android.widget.SearchView" /> ``` Many many thanks! UPDATED: the code of restoreActionBar() ``` public void restoreActionBar() { ActionBar actionBar = getSupportActionBar(); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD); actionBar.setDisplayShowTitleEnabled(true); actionBar.setTitle(mTitle); } ```
