in toolbar.xml

<?xml version="1.0" encoding="utf-8"?> <android.support.v7.widget.toolbar xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:id="@+id/my_toolbar"     xmlns:app="http://schemas.android.com/apk/res-auto"     android:background="#000000"     android:elevation="3dp"     app:theme="@style/themeoverlay.appcompat.dark.actionbar"     app:popuptheme="@style/themeoverlay.appcompat.light">  </android.support.v7.widget.toolbar>

in menu_main.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"     xmlns:tools="http://schemas.android.com/tools"     tools:context=".mainactivity">      <item         android:id="@+id/action_search"         android:orderincategory="200"         android:title="@string/action_search"         android:icon="@drawable/ic_action_search"         app:showasaction="ifroom|collapseactionview"         app:actionviewclass="android.support.v7.widget.searchview"/>  </menu>

and in mainactivity.java oncreate,

protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          toolbar = (toolbar) findviewbyid(r.id.tool_bar);         setsupportactionbar(toolbar);         getsupportactionbar().setdisplayshowtitleenabled(false);         //toolbar.setnavigationicon(r.mipmap.logo9);         toolbar.settitle("");         toolbar.setsubtitle("");

......

@override     public boolean oncreateoptionsmenu(menu menu) {         getmenuinflater().inflate(r.menu.menu_main, menu);          searchview searchview = (searchview) menu.finditem(r.id.action_search).getactionview();         searchmanager searchmanager = (searchmanager) getsystemservice(search_service);         searchview.setsearchableinfo(searchmanager.getsearchableinfo(getcomponentname()));          return super.oncreateoptionsmenu(menu);     }

and in activity_main.xml, include toolbar,

<include         android:id="@+id/tool_bar"         layout="@layout/tool_bar"         ></include>

if search button android view, can hide calling view.setvisibility(view.gone).

if have instead defined menu xml resource , loaded in activity, don't load menu resource unless user logged in. done in public boolean oncreateoptionsmenu(menu menu) of activity.

if go activity after logging in, use separate toolbar there, icon here, without 1 in login activity.

please provide more information on how added search icon toolbar in first place, able more.

edit:

you can use webview.geturl() method url of displayed website, if login page on login.php, can if url that, , not show search icon. example can check url string.contains(), like: .contains("login.php"). , if true don't show button.
