Scroll Down To Search Recycler View

An easy way to search in your recycler view without having an always-on display search view.

How does it work?

Ever wanted a recycler view with a search bar? That's a simple library that lets you wrap your recyclerView into my custom layout which provides a hidden searchview which you can show by scrolling up/down the recycler.

Include

To include this library in your Android project you have to use gradle.

compile 'com.nicolettilu:hiddensearchwithrecyclerview:0.0.2'

Setup

Here's how it works:

<com.nicolettilu.hiddensearchwithrecyclerview.HiddenSearchWithRecyclerView
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</com.nicolettilu.hiddensearchwithrecyclerview.HiddenSearchWithRecyclerView>

You need to wrap your RecyclerView with the custom layout the library provides. At the moment the library provides this configurations:

<attr name="filterWhileTyping" format="boolean"/> <!-- default value: true -->
<attr name="scrollToTopBeforeShow" format="boolean" /> <!-- default value: false -->
<attr name="scrollToBottomBeforeHide" format="boolean" /> <!-- default value: false -->
<attr name="visibleAtInit" format="boolean" /> <!-- default value: false -->
<attr name="hideAtScroll" format="boolean" /> <!-- default value: true -->

You can customize thos attributes in the XML file:

<com.nicolettilu.hiddensearchwithrecyclerview.HiddenSearchWithRecyclerView
        android:id="@+id/hidden_search_with_recycler"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:scrollToBottomBeforeHide="true"
        app:scrollToTopBeforeShow="true"
        app:filterWhileTyping="false"
        app:visibleAtInit="true">
        <!-- your RecyclerView here -->
</com.nicolettilu.hiddensearchwithrecyclerview.HiddenSearchWithRecyclerView>

And in code as well:

val hiddenSearchWithInRecycler = findViewById(R.id.hidden_search_with_recycler) as HiddenSearchWithRecyclerView

hiddenSearchWithInRecycler.hideAtScroll = true
hiddenSearchWithInRecycler.visibleAtInit = false
hiddenSearchWithInRecycler.scrollToBottomBeforeHide = false
hiddenSearchWithInRecycler.scrollToTopBeforeShow = false
hiddenSearchWithInRecycler.filterWhileTyping = true

Here as some example of the results:

  • Default example (no configurations set)

  • Scroll at top/bottom before hide/show SearchView example

  • SearchView shown at init example
