How to add a SearchView to my existing “contacts” project?

I have a project that I made before. The application is working exactly like the "contacts" application in all phones. I'm storing the information in one DataBase and I have list view. Now, I want to add one searchView to this app.

that i want to Search in all the fields(name,phone number,email,...) of DataBase by Typing each character and show the results in ListView.

MainActivity

protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

SQLiteDatabase sqLiteDatabase = getBaseContext().openOrCreateDatabase("ContactsDB.db", MODE_PRIVATE, null);

lv = (ListView) findViewById(R.id.contactListView2);
buttonAdd = (Button) findViewById(R.id.buttonAdd);

String tempSQL = "CREATE TABLE IF NOT EXISTS contactsList(_id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,firstName TEXT,lastName TEXT,phone TEXT,email TEXT,address TEXT,note TEXT);";
sqLiteDatabase.execSQL(tempSQL);
Log.d(TAG, "onCreate: Table created");

db = openOrCreateDatabase("ContactsDB.db", MODE_PRIVATE, null);

//show name in listView

Cursor cursor2 = db.rawQuery("SELECT firstName FROM contactsList;", null);
ArrayList ar = new ArrayList();//new

while (cursor2.moveToNext())
ar.add(cursor2.getString(0));


ArrayAdapter arrayAdapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, ar);
lv.setAdapter(arrayAdapter);
Log.d(TAG, "onCreate: showlist : list showing in listview now.");

//setting for showing the edit layout

lv.setOnItemClickListener(new AdapterView.OnItemClickListener()
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l)
Cursor cr = db.rawQuery("SELECT * FROM contactsList WHERE firstName='"+lv.getItemAtPosition(i).toString()+"'",null);
StringBuffer sb = new StringBuffer();
while(cr.moveToNext())
sb.append(cr.getString(0)+"n");

Intent showAddLayout = new Intent(MainActivity.this, editContact.class);
showAddLayout.putExtra("name",sb.toString());
startActivity(showAddLayout);

);



//button click listener to show other LayOut or page

buttonAdd.setOnClickListener(new View.OnClickListener()
@Override
public void onClick(View view)

Intent showAddLayout = new Intent(MainActivity.this, addNewContact.class);
startActivity(showAddLayout);



);

//end of onCreate


and this is the picture of my simple app

Any help is appreciated. Thanks!

What do you want to search? Try to add more information, in common:

in activity_menu.xml add

<item
android:id="@+id/action_search"
android:icon="@android:drawable/ic_search_category_default"
android:title="@string/menu_search"
app:actionViewClass="android.widget.SearchView"
app:showAsAction="ifRoom|collapseActionView" />


then add action.items.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/menu_search"
android:icon="@android:drawable/ic_search_category_default"
android:title="@string/menu_search"
app:actionViewClass="android.widget.SearchView"
app:showAsAction="ifRoom|collapseActionView" />
</menu>


in activity.java, declare

private SearchView mSearchView;


in onCreate,add

Intent intent = getIntent();
if (Intent.ACTION_SEARCH.equals(intent.getAction()))
mSearchString = intent.getStringExtra(SearchManager.QUERY);
//System.out.println(query);



in onCreateOptionsMenu

getMenuInflater().inflate(R.menu.menu_main, menu);
MenuItem searchMenuItem = menu.findItem(R.id.action_search);
mSearchView = (SearchView) MenuItemCompat.getActionView(searchMenuItem);
setupSearchResult(searchMenuItem);


And, add

private void setupSearchResult(MenuItem searchItem)
SearchManager searchManager =
(SearchManager) getSystemService(Context.SEARCH_SERVICE);
mSearchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));



Hope, I didn't miss nothing important.
