I have a PreferenceScreen that has a PreferenceScreen within it. I am able to display a summary in my outer most PreferenceScreen on launch and also update the summaries onSharedPreferenceChanged, but my inner PreferenceScreen (in xml it has string #string/advanced) does not get the initial value...it does update onSharedPreferenceChanged. I need the intial to display as well. Here is my XML:
<?xml version="1.0" encoding="utf-8"?>

Here is a code snippet:
in OnCreate I call this:
for(int i=0;i<getPreferenceScreen().getPreferenceCount();i++){
initSummary(getPreferenceScreen().getPreference(i));
}
private void initSummary(Preference p) {
if (p instanceof PreferenceCategory){
PreferenceCategory pCat = (PreferenceCategory)p;
for(int i=0;i<pCat.getPreferenceCount();i++){
initSummary(pCat.getPreference(i));
}
}else{
updatePrefSummary(p);
}
}
private void updatePrefSummary(Preference p) {
if (p instanceof ListPreference) {
ListPreference listPref = (ListPreference) p;
p.setSummary(listPref.getEntry());
}
}
Then in onSharedPreferenceChanged:
#Override
public void onSharedPreferenceChanged(SharedPreferences sp, String key) {
Log.i(DEBUG_TAG, "value of key is " + key);
Preference pref = findPreference(key);
...
updatePrefSummary(findPreference(key));
}
First, I have these constants in another class to reference:
public static final String PREF_TIME = "pref_time";
public static final String PREF_DATE = "pref_date";
public static final String PREF_SPEED = "pref_speed";
public static final String PREF_MEASUREMENT = "pref_measurement";
In order to get access to the embedded PreferenceScreen within the Preference Screen I do this:
// enable summary of one deep preferenceScreen
Preference advancedSpeedPref = (Preference) findPreference(ACCUWX.Preferences.PREF_SPEED);
ListPreference listPref1 = (ListPreference) advancedSpeedPref;
advancedSpeedPref.setSummary(listPref1.getEntry());
Preference advancedMeasurementPref = (Preference) findPreference(ACCUWX.Preferences.PREF_MEASUREMENT);
ListPreference listPref2 = (ListPreference) advancedMeasurementPref;
advancedMeasurementPref.setSummary(listPref2.getEntry());
Preference advancedTimeformatPref = (Preference) findPreference(ACCUWX.Preferences.PREF_TIME);
ListPreference listPref3 = (ListPreference) advancedTimeformatPref;
advancedTimeformatPref.setSummary(listPref3.getEntry());
Preference advancedDateformatPref = (Preference) findPreference(ACCUWX.Preferences.PREF_DATE);
ListPreference listPref4 = (ListPreference) advancedDateformatPref;
advancedDateformatPref.setSummary(listPref4.getEntry());
Works like a charm!

I am new to android. Please help me how can i achieve this
I am trying to make a setting menu with cardView and Preference, but I am not sure how to combine these two... Here's the screenshot and I want to move the ListPreference and PreferenceScreen entries into the setting cardView above.
Here's the preference.xml The layout/setting_group is a cardview
<PreferenceScreen
android:layout="#layout/setting_title_top"
android:title = "Padding" />
<PreferenceScreen
android:layout="#layout/setting_group">
</PreferenceScreen>
<ListPreference
android:id="#+id/list"
android:layout="#layout/setting_menu"
android:dialogTitle = "title one"
android:key = "key_1"
android:title = "ListPreference"
android:summary = "Summary"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</ListPreference>
<PreferenceScreen
android:layout="#layout/setting_menu"
android:key="Key two"
android:summary="Summary"
android:title="PreferenceScreen" />
<PreferenceScreen
android:layout="#layout/setting_title"
android:title = "Another Setting" />
The PreferenceScreen is a container, you are opening and closing him with noting inside.
You can create preferences like that:
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<EditTextPreference
android:capitalize="words"
android:defaultValue="#string/default_value" <!--The initial state of the preference -->
android:key="#string/pref_key" <!-- The key for retrieve the preference -->
android:singleLine="true"
android:title="#string/pref_title" /> <!-- The title who is showing above the preference -->
</PreferenceScreen>
Edit: Create a xml file to with the layout of your preferences and create and Activity, example:
public class SettingsActivity extends PreferenceActivity
implements Preference.OnPreferenceChangeListener {
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.pref_general);
bindPreferenceSummaryToValue(findPreference(getString(R.string.pref_key))); // Is deprecated, but still a good option to no need change the values manually.
}
private void bindPreferenceSummaryToValue(Preference preference) {
preference.setOnPreferenceChangeListener(this);
onPreferenceChange(preference, PreferenceManager
.getDefaultSharedPreferences(preference.getContext())
.getString(preference.getKey(), ""));
}
#Override
public boolean onPreferenceChange(Preference preference, Object value) {
String stringValue = value.toString();
preference.setSummary(stringValue);
return true;
}
}
How can i save value as float from EditTextPreference?
I follow this PreferenceActivity: save value as integer
But i did not work for me.
my preference file is
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory
android:title="Taxes"
android:key="first_category">
<CheckBoxPreference
android:key="include_taxes"
android:summary="Include or Exclude taxes"
android:title="Include Taxes"
android:defaultValue="true"
/>
<PreferenceScreen
android:key="Entering_Taxes"
android:title="Enter the Values"
android:dependency="include_taxes"
android:persistent="false">
<EditTextPreference
android:key="ED_tax"
android:title="E.D Tax"
android:summary="Define E.D Tax"
android:dialogTitle="Set E.D Tax"
android:dialogMessage="Enter the value"
android:defaultValue='7.30'/>
</PreferenceScreen>
</PreferenceCategory>
I have to add all values of taxes.
say you can get string of editTextPreference like this,
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this);
String value = preferences.getString("SomeKey", "");
so convert that string to float like this:
float f = Float.valueOf(value);
I have a preferences.xml and Settings.java... In the onCreate method I want to set the summary of the preferences... Could someone guide me what is the best way to do it???
What I know is that one way of doing is
activityName_text = (EditTextPreference) findPreference("activityName");
activityName_text.setSummary(activityName_text.getText());
but for each key if I follow the above pattern I feel that the code will be bad...
Preferences.xml:
<PreferenceScreen android:title="Header" >

android:defaultValue="TestRequest"
android:key="activityName"
android:title="activityName" />

Use like this its always better to set summary from prefrence.xml, I am giving one example I am using this code and its working perfectly
<PreferenceCategory

android:title="Post on Facebook Wall" />
</PreferenceCategory>
You can put all your keys into a string-array resource and iterate over it on onCreate()
final String[] keys = getResources().getStringArray(R.array.keys) ; // all your keys here
SharedPreferences p = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
for (int i = 0; i < keys.length; i++) {
setPreferenceSummary(p, keys[i]);
}
private void setPreferenceSummary(SharedPreferences sharedPreferences, String key) {
final Preference p = findPreference(key);
if(p instanceof EditTextPreference)
{
p.setSummary(sharedPreferences.getString(key, (String)p.getSummary()));
}
else if(p instanceof ListPreference)
{
p.setSummary((String)((ListPreference) p).getEntry());
}
}
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
setPreferenceSummary(sharedPreferences, key);
}
i'm using this code in an activity
protected void onResume() {
super.onResume();
prefs = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
System.out.println(connections);
String dir = prefs.getString("download_directory", "Download");
System.out.println(dir);
}

public class Preferences extends PreferenceActivity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.preferences);
}
}
The problem is, when i get "connections" value it gives me the correct int, instead the getString for key "download_directory" always gives me the default value "Download"
getString for key "download_directory" always gives me the default
value "Download"
This can only happen if "download_directory" is not set at all!
