The simplest way to use searchview

As the name suggests, searchview is a search view, which is similar to the automatically matched input box described earlier. However, he has his own listener and can get the user input result in real time. For the searchview control, I strongly recommend you place it on the actionbar to highlight the search function. However, the actionbar knowledge may be involved here, so here we will show you what this control is.

Layout File

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <requestFocus />    <SearchView        android:id="@+id/searchView_id"        android:layout_width="match_parent"        android:layout_height="wrap_content" />    <ListView        android:id="@+id/listView_id"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1" >    </ListView>    </LinearLayout>

Mainactivity. Java

Package COM. kale. searchview; import android. app. activity; import android.
