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()));

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.
