CHAPTER 14: Android Search 507
**************************************************
* regular_activity_prompt
**************************************************
-->
<string name="regular_activity_prompt">
This is a sample application to test how QSB and Search Key
interacts with activities. This application has 4 activities
including this one. The activity you are looking at is
called a Regular Activity and is one of 4. The other three
you can access through the menu.
\n\n
This activity is a regular activity that is unaware of
any search capabilities. If you click search key now
it will invoke the global search.
\n
\nThe other activities demonstrate:`
\n\n1) No search Activity: An activity that disables search
\n2) Invoke search: programatically invoke global search
\n3) Local Search Activity: Invoke Local Search
\n
\nYour debug will appear here
</string>
<!--
**************************************************
* no_search_activity_prompt
**************************************************
-->
<string name="no_search_activity_prompt">
In this activity the onSearchRequested
returns a false. The search button
should be ignored now.
\n
\nYou can click back now to access the
previous activity and use the menus again
to choose other activities.
</string>
<!--
**************************************************
* search_activity_prompt
**************************************************
-->
<string name="search_activity_prompt">
This is called a search activity or search results activity. This activity
is invoked by clicking on the search key when
some other activity uses this activity as its
search results activity.
\n\n
Typically you can retrieve the query string
from the intent to see what the query is.
</string>
<!--
**************************************************
* search_invoker_activity_prompt
**************************************************
-->
<string name="search_invoker_activity_prompt">
In this activity a search menu item is used
to invoke the default search. In this case
as there is no local search for this activity
specified global search is invoked. Use the
menu button to see the "search" menu. when you
click on that search menu you will see the
global search.
</string>
<!--
**************************************************
* local_search_enabled_activity_prompt
**************************************************
-->
<string name="local_search_enabled_activity_prompt">
This is a very simple activity that has indicated through
the manifest file that there is a an associated search
activity. With this association when the search key is
pressed the local search is presented instead of global.
\n\n
You can see the local nature of it by looking at the
label of the QSB and also the hint in the QSB. Both
came from the search metadata.
\n\n
Once you click on the query icon, it will transfer
you to the local search activity.
