xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
app:theme="#style/ThemeOverlay.AppCompat.ActionBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
app:navigationContentDescription="#string/abc_action_bar_up_description"
android:background="?attr/colorPrimary"
app:navigationIcon="?attr/homeAsUpIndicator"
app:title="Setting Page"
/>
setting_preferences.xml (path is : res/xml) code :
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory
android:key="setting_title_title_category"
android:title="Title options">
<CheckBoxPreference
android:id="#+id/setting_title_show_id"
android:key="setting_title_show"
android:title="Show Main Title"
android:summary="Show/hide MainPage title"
android:checked="true"/>
<EditTextPreference
android:key="setting_title_text"
android:title="Set Main Title"
android:summary="Change MainPage title"

android:dialogMessage="Change title please..."/>
</PreferenceCategory>
<PreferenceCategory
android:key="setting_title_font_category"
android:title="Font options">
<ListPreference
android:key="setting_title_font_color"

android:summary="Change title font colors"
android:entries="#array/colors"
android:entryValues="#array/colors"
android:dialogTitle="Change font color" />
</PreferenceCategory>
</PreferenceScreen>
SettingPage code :
public class SettingPage extends PreferenceActivity implements SharedPreferences.OnSharedPreferenceChangeListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getFragmentManager().beginTransaction().replace(android.R.id.content, new MyPreferenceFragment()).commit();
}
#Override
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
if (key.equals("setting_title_font_color")) {
// get preference by key
Preference pref = findPreference(key);
// do your stuff here
}
if (key.equals("setting_title_show")){
Preference pref = findPreference(key);
}
}
public static class MyPreferenceFragment extends PreferenceFragment {
#Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.setting_prefrences);
}
}
How can it? show setting_preferences.xml beloe ToolBar .

I believe you can use a normal Activity / AppCompatActivity with a simple layout that contains the Toolbar. Then in the content area of the Activity layout, use a PreferenceFragment to show the PreferenceScreen.

How to set PreferenceScreen into other layout in android

I want use PreferenceScreen in my application, and create XML layout for this activity in res/xml/setting_preference.xml. but this XML layout is very simple, i want use this layout in another layout.
For example : i want use setting_preference.xml into setting_activity.xml , setting_activity.xml path is res/layout/setting_activity.xml.
How can i it?
setting_preference XML code:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory
android:key="setting_title_title_category"
android:title="Title options">
<CheckBoxPreference
android:id="#+id/setting_title_show_id"
android:key="setting_title_show"
android:title="Show Main Title"
android:summary="Show/hide MainPage title"
android:checked="true"/>
<EditTextPreference
android:key="setting_title_text"
android:title="Set Main Title"
android:summary="Change MainPage title"
android:dialogTitle="Change Title"
android:dialogMessage="Change title please..."/>
</PreferenceCategory>
<PreferenceCategory
android:key="setting_title_font_category"
android:title="Font options">
<ListPreference
android:key="setting_title_font_color"
android:title="Title font colors"
android:summary="Change title font colors"
android:entries="#array/colors"
android:entryValues="#array/colors"
android:dialogTitle="Change font color" />
</PreferenceCategory>
<RingtonePreference
android:title="tes"/>
</PreferenceScreen>
setting_activity XML code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.tellfa.nikandroid.mytestdbproject.SettingPage">
</RelativeLayout>
Setting Page code:
public class SettingPage extends PreferenceActivity implements SharedPreferences.OnSharedPreferenceChangeListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getFragmentManager().beginTransaction().replace(android.R.id.content, new MyPreferenceFragment()).commit();
}
#Override
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
if (key.equals("setting_title_font_color")) {
// get preference by key
Preference pref = findPreference(key);
// do your stuff here
}
if (key.equals("setting_title_show")){
Preference pref = findPreference(key);
}
}
public static class MyPreferenceFragment extends PreferenceFragment {
#Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.setting_prefrences);
}
}
}

Add a frameLayout where you want to load your xml preference file in the layout xml file and implement PreferenceFragment in that activity.

Preference Menu on 10 inch tablet

I am trying to figure out why the layout of my Preference menu is displayed in a false way on 10' tablets when using it in landscape mode. It looks like the lines that are to the right of the Checkboxes are actually to the left of them. You can see this here http://imageshack.us/photo/my-images/109/schnappschuss2013052109.png/
On 7' tablets, everything works like expected to do.
My menu looks like that:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
<PreferenceCategory
android:title="#string/pref_message"
android:key="pref_key_message_settings">

android:defaultValue="10Byte" />
</PreferenceCategory>
<PreferenceCategory
android:title="#string/pref_about"
android:key="pref_key_settings_about">
<Preference android:title="#string/prefs_about_app" >
<intent android:action="AboutActivity"/>
</Preference>
</PreferenceCategory>
</PreferenceScreen>
and is loded with:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Show the Up button in the action bar.
getActionBar().setDisplayHomeAsUpEnabled(true);
// Display the fragment as the main content.
getFragmentManager().beginTransaction()
.replace(android.R.id.content, new SettingsMenuFragment())
.commit();
}
public static class SettingsMenuFragment extends PreferenceFragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.app_prefs);
}
}

I had the same problem. My solution is to extend SettingsActivity from usual Activity, not from PreferenceActivity. But SettingsFragment should extend PreferenceFragment of course. It helped me, hope this solves your issue too.

How to use Checkboxes for PreferenceActivity class in android

I have MenuSettings in which I have PreferenceActivity class. In PreferenceActivity I have displayed checkboxPreference like below.
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
<PreferenceCategory
android:title="Options">
<CheckBoxPreference
android:key="pref_opt1"
android:title="Option 1"
android:summary="Tick to set this option"
android:defaultValue="true"
/>
<CheckBoxPreference
android:key="pref_opt2"
android:title="Option 2"
android:summary="Tick to set this option"
android:defaultValue="true"
/>
</PreferenceCategory>
</PreferenceScreen>
I want to use checkboxes to perform function for synchronization that I have build, But Please can any body let me know how to use checkboxes in PreferenceActivity. Is there any need to create another Activity? or we can perform function in same PreferenceActivity?
here is my PreferenceActivity:
public class SharedPref extends PreferenceActivity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.sharedpref);
}
// StorePreference method{
}
// readPreferences method{
}
}

UI refreshing at PreferenceActivity

I have a PreferenceActivity where I represent a setting UI, when I press the first checkbox then the second checkbox becomes visible. On the other hand, when the first checkbox is unchecked the second checkbox is hidden(and gets a default value to false).
The problem is that I need my UI screen to be refreshed the moment I check(or uncheck) the first checkbox because right now with that code I need to go to another Activity (e.g when I press the back button) and then get back to the PreferenceActivity again in order to see the changes on my UI.
Code for PreferenceActivity:
public class SetPreference extends PreferenceActivity implements
OnSharedPreferenceChangeListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.checkboxpref);
}
#Override
protected void onStart() {
super.onStart();
Preference checkbox = findPreference("checkBox_Schedule");
SharedPreferences prefs = PreferenceManager
.getDefaultSharedPreferences(this);
if (prefs.getBoolean("checkBox", true)) {
} else {
((PreferenceGroup) findPreference("category_second"))
.removePreference(checkbox);
SharedPreferences.Editor geted = prefs.edit();
geted.putBoolean("checkBox_Schedule", false);
geted.commit();
}
}
#Override
protected void onResume() {
super.onResume();
}
#Override
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences,
String key) {
// TODO Auto-generated method stub
}
}
Code for XML:
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
<PreferenceCategory
android:summary="Username and password information"
android:title="Login information" >
<EditTextPreference
android:key="username"
android:summary="Please enter your login username"
android:title="Username" />
<EditTextPreference
android:inputType="textPassword"
android:key="password"
android:summary="Enter your password"
android:title="Password" />
</PreferenceCategory>
<PreferenceCategory
android:summary="Username and password information"
android:title="Settings"
android:key="category_first" >
<CheckBoxPreference
android:key="checkBox"
android:summary="On/Off"
android:title="Keep me logged in" />
<ListPreference
android:entries="#array/listOptions"
android:entryValues="#array/listValues"
android:key="listpref"
android:summary="List preference example"
android:title="List preference" />
</PreferenceCategory>
<PreferenceCategory
android:summary="schedule"
android:key="category_second"
android:title="Schedule" >
<CheckBoxPreference
android:key="checkBox_Schedule"
android:summary="On/Off"
android:title="Keep me logged in" />
</PreferenceCategory>
</PreferenceScreen>
Thank you for your time.

Ok then just restart the activity when the checkbox is selected/deselected:
startActivity(new Intent(PreferencesActivity.this, PreferencesActivity.class));
finish();
Consider using onPreferenceSelectedListener for the first checkbox to detect the act of checking/unchecking the preference.
