Searching For Food

Step #2: Integrate the Search in the Application.............................

Now we need to tell Android that this application is searchable and how to

do the search.

First, we need to overhaul our AndroidManifest.xml file to indicate that the

LunchList activity is both searchable and the activity to launch to conduct a

search:

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="apt.tutorial"

android:versionCode="1"

android:versionName="1.0">

<application android:label="@string/app_name">

<activity android:name=".LunchList"

android:label="@string/app_name">

<intent-filter>

<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />

</intent-filter>

<intent-filter>

<action android:name="android.intent.action.SEARCH" />

<category android:name="android.intent.category.DEFAULT" />

</intent-filter>

<meta-data android:name="android.app.searchable"

android:resource="@xml/searchable" />

<meta-data android:name="android.app.default_searchable"

android:value=".LunchList" />

</activity>

<activity android:name=".DetailForm">

</activity>

<activity android:name=".EditPreferences">

</activity>

</application>

</manifest>

The second indicates that the LunchList activity will handle

any local search requests. The android.app.searchable metadata element

names @xml/searchable as being the configuration details for the search

itself. So, add a LunchList/res/xml/searchable.xml file with the following

content:

<searchable xmlns:android="http://schemas.android.com/apk/res/android"

android:label="@string/searchLabel"

android:hint="@string/searchHint" />
