Get EditTextPreference value

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()));

Answer

Your value will be stored in a shared preference file.

Check my little example below:

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

  2. 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>
    
  3. 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);
            }
        }
    
  4. Use a SharedPreference object to insert and get your String value.
