SearchBar
public
class
SearchBar
extends Toolbar
java.lang.Object | ||||
↳ | android.view.View | |||
↳ | android.view.ViewGroup | |||
↳ | androidx.appcompat.widget.Toolbar | |||
↳ | com.google.android.material.search.SearchBar |
The SearchBar
represents a floating search field with affordances for search and
navigation.
Note: SearchBar
does not support the Toolbar.setTitle(int)
and Toolbar.setSubtitle(int)
methods, or their corresponding xml attributes. Instead, use setHint(int)
or setText(int)
, or their corresponding xml attributes, to provide a text affordance for your SearchBar
.
The example below shows how to use the SearchBar
and SearchView
together:
<androidx.coordinatorlayout.widget.CoordinatorLayout android:layout_width="match_parent" android:layout_height="match_parent"> <!-- NestedScrollingChild goes here (NestedScrollView, RecyclerView, etc.). --> <androidx.core.widget.NestedScrollView android:layout_width="match_parent" android:layout_height="match_parent" app:layout_behavior="@string/searchbar_scrolling_view_behavior"> <!-- Screen content goes here. --> </androidx.core.widget.NestedScrollView> <com.google.android.material.appbar.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <com.google.android.material.search.SearchBar android:id="@+id/search_bar" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="@string/searchbar_hint" /> </com.google.android.material.appbar.AppBarLayout> <com.google.android.material.search.SearchView android:layout_width="match_parent" android:layout_height="match_parent" android:hint="@string/searchbar_hint" app:layout_anchor="@id/search_bar"> <!-- Search suggestions/results go here (ScrollView, RecyclerView, etc.). --> </com.google.android.material.search.SearchView> </androidx.coordinatorlayout.widget.CoordinatorLayout>
