There is a search button in the menu. It is necessary either:

  • programmatically emulate pressing the search button in a menu or

  • activate SearchView widget

    Any way will do.

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" xmlns:tools="http://schemas.android.com/tools" tools:context=".activity.MyActivity"> <item android:id="@+id/action_search" android:icon="@drawable/ic_search_white_24dp" android:title="@string/search_hint" app:showAsAction="always|collapseActionView" app:actionViewClass="android.support.v7.widget.SearchView" /> </menu>

Activation code:

  boolean onCreateOptionsMenu( Menu menu) { getMenuInflater().inflate( R.menu.menu_main, menu); menuItem = menu.findItem( R.id.action_search); searchView = (SearchView) menuItem.getActionView(); return true; }

There is a MenuItem menuItem and SearchView searchView, now you need to activate SearchView in some way.

    1. MenuItem menuItem; field MenuItem menuItem;

    2. Initialize it in onCreateOptionsMenu - this.menuItem = menu.findItem( R.id.action_search);

    3. Now activate (emulate click) like this: ((SearchView) menuItem.getActionView()).onActionViewExpanded();

    • menuItem.getActionView ()). onActionViewExpanded () partially triggered. The keyboard appears, and the search widget does not open. - Devel0per

    I found a solution that works with collapseActionView in the app:showAsAction="always|collapseActionView" .

    need to call menuItem.expandActionView()
