uisearchbar - Showing a search bar in Android -

i'm having trouble when trying show search bar @ top of app. want bar visible hole application (in activities) when app starts, no need user press button, i'm trying use android's searchable function. here's i've got far:

manifest.xml

<application android:icon="@drawable/icon" android:label="@string/app_name">     <activity android:name=".main"               android:label="@string/app_name">         <intent-filter>             <action android:name="android.intent.action.main" />             <category android:name="android.intent.category.launcher" />         </intent-filter>     </activity>      <activity android:name=".bigimageview">         <intent-filter>             <action android:name="android.intent.action.search" />         </intent-filter>         <meta-data android:name="android.app.searchable"                android:resource="@xml/searchable"/>     </activity>     <!-- declare default searchable activity whole app -->     <meta-data android:name="android.app.default_searchable"            android:value=".bigimageview" />  </application> 

res/xml/searchable.xml

<searchable xmlns:android="http://schemas.android.com/apk/res/android" android:label="@string/app_name" android:hint="@string/search_hint" > 

can accomplish or user need press buttons invoke search bar?

you put

onsearchrequested(); 

in onresume() - search bar hide if component focus.

if that's not want, should implement own search bar (i.e. autocompletetextview).
