কিভাবে সার্চ ভিউ তৈরি করবেন android-studio সাহায্য।প্রথমে অ্যান্ড্রয়েড স্টুডিও ডাউনলোড করে নিন। নিজের কম্পিউটারে ইনস্টল করে এস ডি কে সেটআপ করে নিন। নতুন করে একটা প্রজেক্ট তৈরি করে নিন। স্টেপ গুলো ফলো করে অ্যাপ তৈরি করুন। না পারলে ভিডিও টিউটোরিয়ালটি দেখেন।

03 Step (Create an item view layout)\app\src\main\res\layout\item_view_itechbangla.xml
<?xml version="1.0" encoding="utf-8"?><androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_marginBottom="4dp" app:cardCornerRadius="4dp"> <RelativeLayout android:layout_width="match_parent" android:layout_height="match_parent" android:layout_margin="4dp"> <ImageView android:id="@+id/image_view" android:layout_width="50dp" android:layout_height="50dp" android:padding="2dp" /> <TextView android:id="@+id/text_view1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_toEndOf="@+id/image_view" android:text="Line 1" android:textColor="@android:color/black" android:textSize="20sp" android:textStyle="bold" /> <TextView android:id="@+id/text_view2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@+id/text_view1" android:layout_marginStart="8dp" android:layout_toEndOf="@+id/image_view" android:text="Line 2" android:textSize="15sp" /> </RelativeLayout></androidx.cardview.widget.CardView>
04 Step (Create an Menu View )\app\src\main\res\menu\menu_main_se.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/action_search" android:icon="@drawable/example_menu" android:title="Search" app:actionViewClass="android.widget.SearchView" app:showAsAction="ifRoom|collapseActionView" /></menu>
05 Step (Your View Activity Layout)\app\src\main\res\layout\activity_main.xml
<androidx.recyclerview.widget.RecyclerView android:id="@+id/recycler_view" android:layout_width="match_parent" android:layout_height="match_parent" android:padding="4dp" android:scrollbars="vertical" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toTopOf="parent" />
06 Step (Create a Java Class View )\app\src\main\java\com\example\app\Data_list_calass_leItem.java
