Android Search Recyclerview :
Android Search Recyclerview, Generally data is displayed in the form of listviews in apps, so that data can be dynamically loaded also sometimes the list has to be searched.
Android Recyclerview is mostly used now a days rather than the android listview so that the views get recycled and consumes less storage compared to the listview
Searching a android listview is most common feature used in almost every app so in this android tutorial on recyclerview search we will see how to search the list and show the updated list.
In my previous tutorial Fetching Contacts i had shown you how to fetch contacts and now in this tutorial i will show you how to add search functionality to that recyclerview.
We will be using Android Search Recyclerview just as like textview and edittext but this one comes up with a search functionality.
Based in this example i have also created a app may have a look in play store.
Android Search Recyclerview Video Tutorial :
Follow through this vlog for more in detail implementation of search functionality in android recyclerview.
Easily implement customized search functionality to your recycerview, for more follow this tutorial on Android Search Recyclerview.
Initialization of search view, and adding a hint to be appeared in the searchview
SearchView search;
search = (SearchView) findViewById(R.id.searchView);
search.setQueryHint("Search by Name");
search.setBackgroundColor(Color.parseColor("#ffffff"));
search.setIconified(false);
search.clearFocus();
activity_main
Add a search view to the view above the recyclerview as
<SearchView android:id="@+id/searchView" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="right" android:drawable="@drawable/search_store_icon" android:gravity="center" android:hint="Search by name" android:padding="2dp" android:singleLine="true" android:textColorHint="#000000"></SearchView>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="location.android.com.searchrecyclerview.MainActivity">
<SearchView
android:id="@+id/searchView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:drawable="@drawable/search_store_icon"
android:gravity="center"
android:hint="Search by name"
android:padding="2dp"
android:singleLine="true"
android:textColorHint="#000000"></SearchView>
<android.support.v7.widget.RecyclerView
android:id="@+id/contacts_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/frag"
android:clickable="true" />
</LinearLayout>
MainActivity :
Complete implementation of this tutorial is provided below.Initially we are fetching contacts and then populating them once we finish fetching through a recylerview.
We have also added necessary permissions to fetch contacts that are required based on android versions.
You can also choose the required fields i.e., phone number, name, email-id, image if exist’s and so on depending upon requirement.
