Android Search view not invoking search activity

Please dont mark as duplicate as I have viewed several other same question and those solution didnt worked for me.
category_menu.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/category.search"
android:title="Search"
app:showAsAction="ifRoom|collapseActionView"
app:actionViewClass="android.support.v7.widget.SearchView"/>
</menu>
Mainfest.xml
<activity android:name=".CategoryActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />

</activity>
<activity
android:name=".SearchResultsActivity"
android:label="#string/title_activity_search_results"
android:theme="#style/AppTheme.NoActionBar"
android:launchMode="singleTop">

</intent-filter>
<meta-data android:name="android.app.searchable" android:resource="#xml/searchable" />
<meta-data android:name="android.support.PARENT_ACTIVITY" android:value=".CategoryActivity" />
</activity>
CategoryActivity.java
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.category_menu, menu);
SearchView searchView = (SearchView) menu.findItem(R.id.category_search).getActionView();
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this, SearchResultsActivity.class)));
return true;
}
SearchResultsActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.d(TAG,"Search Began");
setContentView(R.layout.search_results_activity);
handleIntent(getIntent());
}
#Override
protected void onNewIntent(Intent intent) {
handleIntent(intent);
}
private void handleIntent(Intent intent) {
Log.d(TAG, "Herer");
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
//use the query to search your data somehow
Log.d(TAG, query);
}
}
Searchable.xml under res/xml/
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="#string/app_name"
android:hint="Recipe Search" />

you should add onQueryTextListener in searchView.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.category_menu, menu);
SearchView searchView = (SearchView) menu.findItem(R.id.category_search).getActionView();
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView.setSearchableInfo(searchManager.getSearchableInfo(new ComponentName(this, SearchResultsActivity.class)));
searchView..setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
startActivity(CategoryActivity.this, SearchResultActivity.class);
return true;
}
#Override
public boolean onQueryTextChange(String newText) {
return false;
}
});
return true;
}

android hint and label must both be of type "#String/..."
hardcoded text will prevent SearchResultActivity from starting.

if in searchable.xml not contain android:label, it doesn't start SearchResultActivity, make sure you add this code in searchable.xml:
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="#string/app_name" ===================> can not contain empty strings
android:hint="Recipe Search" />

SearchView doesn't start Search Activity but searchbar opens

I'm having trouble creating the search feature for my application. I have followed various tutorials, followed the Android Docs, and other Stack Overflow answers with no success. I have the icon for the each in one activity (ContinentActivity.java) and when clicked the toolbar opens up a search window. However typing data does not register in the SearchResultsActivity. It is never created. Could this be because I am using a toolbar and a menu?

Seems you have missing call to associate SearchView with searchable info within the onCreateOptionsMenu() method? Quote from the training link http://developer.android.com/guide/topics/search/search-dialog.html
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
But since you are not using the same activity for search result, you cannot simply use getComponentName(), but to use new ComponentName(this, SearchResultsActivity.class)

Error and have no clue why :(

i have been trying to figure out how to make a simple search button. I found this (Implementing SearchView in action bar) which i thought would help and i guess it did, i just cant figure out why there is an error here:
SearchableActivity.java
package com.ryan.buttonsimple;
import android.app.SearchManager;
import android.content.Context;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.support.v7.widget.SearchView;
import android.view.Menu;
import android.view.MenuItem;
public class SearchableActivity extends ActionBarActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Get the SearchView and set the searchable configuration
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView searchView = (SearchView) findItemById(R.id.search_view); //**HERE IS THE ERROR! "findItemById" and "search_view" "Cannot resolve method for both**
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false); // Do not iconify the widget; expand it by default
}
#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_searchable, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
here is my searchable.xml file:

Runtime Error because of ListView id

the error causes the program to crash whenever i try to open this page and it says :

and when i try to debug it, it tells me that there is something's source not found
and for the record when i make any other page opens instead of this page it opens without any problems.
REMEMBER GUYS : I'm new in java so don't say big words try to simplify as much as you can
Thanks

In your layout, change:
android:id="#+id/list"
to
android:id="#id/android:list"
and, in your class change:
Sites = (ListView) findViewById(R.id.list);
to
Sites = (ListView) findViewById(android.R.id.list);
