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

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.

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>

There is a data field for intents described in the documentation here.

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?

Add the preference to the preference.xml file:

<Preference android:title="user" android:key="user"/>            

And then you can use a setOnPreferenceClickListener to launch an Intent with extras.

Preference userButton = (Preference) findPreference("user");
userButton.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
    @Override
    public boolean onPreferenceClick(Preference arg0) {
        Intent intent = new Intent(getActivity(), YourTargetActivity.class);
        intent.putExtra(EXTRA, mUser);
        startActivity(intent);
        return true;
    }
});

working for me.

<shortcut
    android:enabled="true"
    android:icon="@mipmap/xxx"
    android:shortcutDisabledMessage="@string/xxx"
    android:shortcutId="xxxx"
    android:shortcutLongLabel="xxx"
    android:shortcutShortLabel="xxx">
    <intent
        android:action="android.intent.action.VIEW"
        android:targetClass="xxx"
        android:targetPackage="xxx">
        <extra
            android:name="intent_name"
            android:value="true" />
    </intent>
</shortcut>

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 );

You can use

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

    <intent android:action="android.intent.action.VIEW"
            android:data="hello world" />

</PreferenceScreen>

to send the intent data. Then in your activity simply use:

getIntent().getDataString()

To send email or rate on market you need to use something like

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

    <intent android:action="android.intent.action.VIEW"
            android:data="market://details?id=com.your_package" />

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

    <intent android:action="android.intent.action.VIEW"
            android:data="mailto:[email protected]" />

</Preference>

Not really an answer to your question, but very much related. Maybe someone will find it useful. For newer API (>11) you have a preference-headers file and you can define custom intents for one of the headers. I was trying to add a custom Extra to one of the headers and the solution I found goes like this:

In your preference-headers.xml:

<header 
        android:fragment="com.mypackage.MyPreference$Prefs1Fragment"
	    android:title="Intent"
        android:summary="Launches an Intent.">
</header>

In your "MyPreference" class (extends PreferenceActivity) you have:

public static class Prefs1Fragment extends PreferenceFragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Intent intent = new Intent(getActivity(), MyTargetActivity.class);
        // set the desired extras, flags etc to the intent
        intent.putExtra("customExtra", "Something that I used to know");
        // starting our target activity
        startActivity(intent);
        // ending the current activity, which is just a redirector to our end goal
        getActivity().finish();
    }
}
