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;
}
}

I'm developing an Android app and I have added several SeekBarPreference elements in my settings page to work as sliders. They have different max values, and I think it's a problem that you cannot see what value you selected. So I wonder what's the best way to show the current value of SeekBarPreference in a preferences activity. Right now I think maybe the summary of the seekBarPreference-element is the best way, but I am open to other suggestions.
This is how the settings activity looks like:
Here's the code I tried so far:
public static class SettingsFragment extends PreferenceFragmentCompat {
#Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
setPreferencesFromResource(R.xml.root_preferences, rootKey);
((SeekBarPreference) findPreference(R.id.seekRounds)).setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
#Override
public boolean onPreferenceChange(Preference preference, Object newValue) {
final int progress = Integer.valueOf(String.valueOf(newValue));
preference.setSummary(String.format("Current value: %d", progress));
}
});
}
And currently I get the error Cannot resolve symbol 'seekRounds'.
Here's my root_preferences.xml:
<androidx.preference.PreferenceScreen xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory app:title="#string/main_settings_header">
<SeekBarPreference
app:key="seekRounds"
android:title="Number of rounds"
android:summary="This is the summary"
android:max="2"
android:progress="0"
android:theme="#style/Base.Widget.AppCompat.SeekBar"
/>
</PreferenceCategory>
Found the answer. Just add app:showSeekBarValue="true" to your SeekBarPreference.
Like this:
<SeekBarPreference
app:key="seekRounds"
android:title="Number of rounds"
android:summary="This is the summary"
android:max="2"
app:showSeekBarValue="true"
android:progress="0"
android:theme="#style/Base.Widget.AppCompat.SeekBar"
/>
I want use PreferenceScreen for my application setting, but i want show this Preferences below the ToollBar.
toolbar.xml code :
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
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: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>
</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.
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">

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.
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);
}
My preferences.xml
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >
<PreferenceCategory android:title="Downloads">
<EditTextPreference
android:key="download_directory"
android:title="#string/download_destination"
android:summary="#string/download_description"
android:defaultValue="FacebookPhotos"
android:dialogTitle="#string/download_destination" />
<CheckBoxPreference android:key="subdir_album"
android:title="#string/download_album"
android:summary="#string/download_album_description" />
</PreferenceCategory>
<PreferenceCategory android:title="Gallery">
<EditTextPreference

public class Preferences extends PreferenceActivity

#Override

{
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!
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.
