How to implement search functionality through custom list adapter?

I want to search my GridView list items which include image and a text field. Please help me out that I can search from my GridView either from search view or edit text from the custom list adapter filter method. Thanks in advance.

This is my main activity 'XML'.

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
android:background="#e9e9e9">

<GridView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/listview"
    android:paddingTop="15dp"
    android:paddingBottom="15dp"
    android:columnWidth="200dp"
    android:numColumns="2"
    android:horizontalSpacing="10dp"
    android:verticalSpacing="20dp"
    android:layout_marginLeft="20dp"
    android:layout_marginRight="20dp"
    android:gravity="center|bottom"
    android:drawSelectorOnTop="true"

    />

</android.support.constraint.ConstraintLayout>
