2. Adding Behaviour (aka Abilities) to our Search

• We need a new resource directory for xml files.
  • Create a new android resource directory called xml
• We need a searchable.xml resource file for our search.
  • Note: this can be named a lot of things but for now use the default of searchable.xml.
• Replace the current element with a searchable element (remember how I replace the PreferenceScreen view?)
• Add a label and hint attribute to your searchable element.

<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
        android:label="@string/app_name"
        android:hint="@string/search_hint" />

• Open our app manifest
• Add our <meta-data> about our search as a child of our Activity element inside the manifest.
  • The meta-data contains a name
  • It also contains a resource @xml/link_to link.
• This tells our activity to be searchable!

<meta-data android:name="android.app.searchable"
            android:resource="@xml/searchable" />

• While inside our manifest, we should also tell our Activity element that we need to add a new action to our <intent-filter> list.
• Our action: android.intent.action.SEARCH

<activity android:name=".MainActivity"
            android:launchMode="singleTop">
  <intent-filter>
      <action android:name="android.intent.action.SEARCH" />
  </intent-filter>
...
</activity>
