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:
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.
