Is there any way to put extras to Intent from preferences ?

Question

Hi i'm launching activity from preferences screen. Activity is shared among three preferences. I wonder if i can set extras for this activity in xml

<Preference
    android:key="action_1"
    android:title="@string/action_1_title"
>
    <intent
        android:action="com.package.SHAREDACTION"
    >

    </intent>
</Preference>

i wonder if i can do something like

<extras>
     <item
      android:name=""
      android:value=""/>
</extras>

All i need to do to pass an integer really. I can different actions and check action instead of extras.

Answer 1

As your extras are not constants, you should pass them in the java code instead of xml.

Intent intent = new Intent( this, YourTargetActivity.class );
intent.putExtra( EXTRAS_KEY, extras );
yourPref.setIntent( intent );

There is a data field for intents described in the documentation here: http://developer.android.com/reference/android/content/Intent.html

It is used in the API demo application for the XML preferences to launch an intent in the Intent Preferences example.

Related example xml from that demo in preferences.xml:

    <PreferenceScreen
            android:title="@string/title_intent_preference"
            android:summary="@string/summary_intent_preference">

        <intent android:action="android.intent.action.VIEW"
                android:data="http://www.android.com" />

    </PreferenceScreen>

Maybe this approach could work for you?

I got an answer, you can use it like this:

<Preference
    android:key="xxx"
    android:title="xxx"
    android:summary="xxx">
   <intent android:action="xxx" >
         <extra android:name="xxx" android:value="xxx" />
    </intent>        

</Preference>

Answer 4

Yea! <extra android:name="xxx" android:value="xxx" /> is working!!! Thanks a lot.
