Get EditTextPreference value

Question

I've created an EditTextPreference and now I want to get the value from any other activity. I've been trying a lot of things but I cannot get it working. Where is this value stored? How can I retrieve it?

EDIT: I want to get the value from a different activity, not the Preferences activity.

settings.xml

<EditTextPreference
    android:title="EditText1"
    android:key="edit1"
    android:defaultValue="0"
    android:dialogIcon="@drawable/fleetespiar"
    android:inputType="number" />

Settings.java (How to do this in a different activity)

Preference edit1= findPreference("edit1");
EditTextPreference editt1 = (EditTextPreference) edit1;

System.out.println(String.valueOf(editt.getText().toString()));

First you need to create an instance of SharedPreferences, then you can call getString() on it, specifying the key for the value.

First of all thank you for your answer. I know how to do it, I know how to get the value when I create the `SharedPreference` and I store it where I want. The problem is that this value is saved automatically. `I've tried with getDefaultSharedPreferences()` but no luck... Maybe the question is not as self-explainable as I tought. Sorry. – anonymous Jul 09 '12 at 08:31

Your value will be stored in a shared preference file.

Check my little example below:

Create a xml directory inside the res directory (resources) of your android project.

Inside your new xml directory you must create a preference.xml file wich will contains your EditTextPreference.

    <?xml version="1.0" encoding="utf-8"?>
    <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
        <EditTextPreference
            android:dialogTitle="My preference"
            android:key="pref"
            android:summary="Enter Your Preference"
            android:title="Edit Text Preference" />
    </PreferenceScreen>

Now create your Preferences class which extends PreferenceActivity.

    import android.content.SharedPreferences;
    import android.content.SharedPreferences.OnSharedPreferenceChangeListener;
    import android.os.Bundle;
    import android.preference.EditTextPreference;
    import android.preference.Preference;
    import android.preference.PreferenceActivity;

        public class Preferences extends PreferenceActivity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
             super.onCreate(savedInstanceState);
             addPreferencesFromResource(R.xml.preferences);
        }
    }

Use a SharedPreference object to insert and get your String value.

@KrLx_roller, you might take a look at [this](http://android-er.blogspot.pt/2010/08/edittextpreference.html) and [this](http://androidpartaker.wordpress.com/tag/edittext-preference-summary/) references. I think they can help you a lot. — yugidroid, Jul 09 '12 at 08:52
Thank you! I Googled and I found the second webpage, not the first one. It's what I was looking for. But it's strange... I did exactly what the example show with no luck... Maybe I forgot something... Thank you! I'll try it now! — anonymous, Jul 09 '12 at 09:49
