Floating Search View

Complete Kotlin/AndroidX port of arimorty/FloatingSearchView

An implementation of a floating search box with search suggestions, also called persistent search bar.

...

Usage

1. In your dependencies, add

implementation 'xyz.quaver:floatingsearchview:1.2.0-rc2'

2. Add a FloatingSearchView to your view hierarchy, and make sure that it takes up the full width and height of the screen
3. Listen to query changes and provide suggestion items that implement SearchSuggestion

Example:

<xyz.quaver.floatingsearchview.FloatingSearchView
    android:id="@+id/floating_search_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:searchBarMarginLeft="@dimen/search_view_inset"
    app:searchBarMarginTop="@dimen/search_view_inset"
    app:searchBarMarginRight="@dimen/search_view_inset"
    app:searchHint="Search..."
    app:suggestionAnimDuration="250"
    app:showSearchKey="false"
    app:leftActionMode="showHamburger"
    app:menu="@menu/menu_main"
    app:elevation="4dp"
    app:close_search_on_keyboard_dismiss="true"/>

Kotlin

binding.searchView.onQueryChangeListener = { oldQuery, newQuery -> {
    //get suggestions based on newQuery
  
    //pass them on to the search view
    binding.searchView.swapSuggestions(newSuggestions);
}

Java

mSearchView.setOnQueryChangeListener((oldQuery, newQuery) -> {
    //get suggestions based on newQuery

    //pass them on to the search view
    mSearchView.swapSuggestions(newSuggestions);

    return Unit.INSTANCE;
});

Left action mode:

The left action can be configured as follows:

Add

app:leftActionMode="[insert one of the options from table below]"

showHamburger
showSearch
showHome
noLeftAction

Listen to hamburger button clicks:

 binding.searchView.onMenuClickListener = object: FloatingSearchView.OnLeftMenuClickListener {
     ...
 }        

To quickly connect your NavigationDrawer to the hamburger button:

binding.menuView.attachNavigationDrawerToMenuButton(mDrawerLayout);

Listen to home (back arrow) button clicks:

binding.menuView.setOnHomeActionClickListener(
      new FloatingSearchView.OnHomeActionClickListener() { ... });       

Configure menu items:

Add a menu resource

app:menu="@menu/menu_main"

In the menu resource, set items' app:showAsAction="[insert one of the options described in the table below]"

never	Puts the menu item in the overflow options popup
ifRoom	Shows an action icon for the menu if the following conditions are met: 1. The search is not focused. 2. There is enough room for it.
always	Shows an action icon for the menu if there is room, regardless of whether the search is focused or not.

Listen for item selections

binding.searchView.onMenuItemClickListener = { item ->

}

Configure suggestion item:

First, implement SearchSuggestion

Optional:

Set a callback for when a given suggestion is bound to the suggestion list.

For the history icons to show, you would need to implement this. Refer to the sample app for an example implementation.

binding.searchView.onBindSuggestionCallback = { binding, item, itemPosition ->
  // suggestionView = binding.root, leftIcon = binding.leftIcon, textView = binding.body
  //here you can set some attributes for the suggestion's left icon and text. For example,
  //you can choose your favorite image-loading library for setting the left icon's image.
});

Styling:

Available styling:

   <style name="SearchView">
           <item name="backgroundColor"></item>
           <item name="viewSearchInputTextColor"></item>
           <item name="viewSuggestionItemTextColor"></item>
           <item name="hintTextColor"></item>
           <item name="dividerColor"></item>
           <item name="clearBtnColor"></item>
           <item name="leftActionColor"></item>
           <item name="menuItemIconColor"></item>
           <item name="suggestionRightIconColor"></item>
           <item name="actionMenuOverflowColor"></item>
   </style>

backgroundColor uses colorSurface value defined in Theme.
To change backgroundColor according to Light/Dark Theme, define colorSurface or use Theme.Material/Theme.MaterialComponents as a parent.
Otherwise, backgroundColor defaults to White.
