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

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 );

Answer 2

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;
    }
});

Answer 3

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

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>

Answer 5

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()

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();
    }
}
