Runtime Change Android material theme - java

I have one setting screen for change app themes at runtime. I know how to create material design theme. I have create one in my style.xml file
Here is code of my style.xml:
<style name="AppTheme" parent="AppTheme.Base"/>
<style name="AppTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/primaryBackground</item>
<item name="colorPrimaryDark">#color/primaryBackground</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="android:colorControlNormal">#color/primaryBackground</item>
<item name="android:colorControlActivated">#color/primaryBackground</item>
<item name="android:colorControlHighlight">#color/primaryBackground</item>
<item name="android:textColorPrimary">#color/primaryBackground</item>
<item name="android:textColorSecondary">#color/primaryBackground</item>
<item name="android:windowAnimationStyle">#style/WindowAnimationTransition</item>
<item name="android:textCursorDrawable">#drawable/cursor_indicator</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
Now I want to change runtime app theme from green to purple or yellow. Anything can any one tell me how can I create a color picker from theme selection and how can I create multiple themes in my style.xml for change it to runtime.


Have you seen this demo?

See this class:
public class Preferences {
private static final BoolToStringPref[] PREF_MIGRATION = new BoolToStringPref[]{
new BoolToStringPref(R.string.pref_dark_theme, false,
R.string.pref_theme, R.string.pref_theme_value_red),
};
public static void sync(PreferenceManager preferenceManager) {
Map<String, ?> map = preferenceManager.getSharedPreferences().getAll();
for (String key : map.keySet()) {
sync(preferenceManager, key);
}
}
public static void sync(PreferenceManager preferenceManager, String key) {
Preference pref = preferenceManager.findPreference(key);
if (pref instanceof ListPreference) {
ListPreference listPref = (ListPreference) pref;
pref.setSummary(listPref.getEntry());
}
}
/**
* Migrate from boolean preferences to string preferences. Should be called only once
* when application is relaunched.

* #param context application context

*/
public static void migrate(Context context) {
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(context);
SharedPreferences.Editor editor = sp.edit();
for (BoolToStringPref pref : PREF_MIGRATION) {

}
if (pref.hasOldValue(context, sp)) {

}
}
editor.apply();
}
public static void applyTheme(ContextThemeWrapper contextThemeWrapper) {
if (Preferences.darkThemeEnabled(contextThemeWrapper)) {
contextThemeWrapper.setTheme(R.style.AppTheme_Blue);
}
}
private static boolean darkThemeEnabled(Context context) {

Rarely Occured Error: Binary XML file line #196: <item> tag requires a 'drawable' attribute or child tag defining a drawable

I have an issue its error: Binary XML file line #196: tag requires a 'drawable' attribute or child tag defining a drawable
This error occurs sometimes and sometimes not for the same actions where I use animation-list. It causes a crash. After the crash, I reopen the app and do the same thing, but I don't have that type of error.
An error occurred approximately one time every 10 actions are the same. I can't get what is wrong and why it occurs rarely and not all time.
Every attempt is after creating activity.

How to Set the theme in Fragments programmatically?

I wrote a code for setting a theme for activities setTheme(R.style.darkTheme); but i don't know how to write in fragments activity to set the theme.The code is for activities
if(sharedPref.loadNightModeState()==true)
{
setTheme(R.style.darkTheme);
}
else {
setTheme(R.style.AppTheme);
}
This is my style.xml
<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="backgroundcolor">#color/background</item>
<item name="textcolor">#color/textcolor</item>
<item name="buttoncolor">#color/red</item>
</style>
<style name="darkTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#212121</item>
<item name="colorPrimaryDark">#000000</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="backgroundcolor">#303030</item>
<item name="textcolor">#color/white</item>
<item name="buttoncolor">#color/red</item>
</style>
</resources>
This is my fragment code
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.fragment_state, container, false);
sharedPref=new SharedPref(getActivity());
if(sharedPref.loadNightModeState()==true)
{
setTheme(R.style.darkTheme);
}
else {
setTheme(R.style.AppTheme);
}
return view;
}
error is coming in this setTheme(R.style.AppTheme) line .

How can I get dark mode to work on my app?

I have set up a ListPreference with different values for the user's dark mode preference. Right now, I just want the app to work with the new dark mode implementation introduced in Android Q. If I set the system dark mode, the app changes because I have enabled isforcedarkallowed in styles.xml.
SettingsFragment:
public static class SettingsFragment extends PreferenceFragmentCompat {
#Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
setPreferencesFromResource(R.xml.root_preferences, rootKey);
PreferenceScreen screen = getPreferenceScreen();
final ListPreference listPreference = (ListPreference) findPreference("theme");
Preference preference = (Preference) findPreference("notq");
int api = Integer.valueOf(android.os.Build.VERSION.SDK_INT);
if (api > 28) {
screen.removePreference(preference);
}
if (api < 29) {
screen.removePreference(listPreference);
}
listPreference.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {
#Override
public boolean onPreferenceChange(Preference preference, Object newValue) {
listPreference.setValue(newValue.toString());
theme = String.valueOf(listPreference.getEntry());
Log.d("debug", theme);
if (theme.equals("Light")) {
AppCompatDelegate.setDefaultNightMode(MODE_NIGHT_NO);
}
if (theme.equals("Dark")) {
AppCompatDelegate.setDefaultNightMode(MODE_NIGHT_YES);
}
if (theme.equals("System default")) {
AppCompatDelegate.setDefaultNightMode(MODE_NIGHT_FOLLOW_SYSTEM);
}
return true;
}
});
}
}
Arrays.xml (values for dark mode preference)
<resources xmlns:tools="http://schemas.android.com/tools" xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Reply Preference -->
<string-array name="theme_entries">
<item>Light</item>
<item>Dark</item>
<item>System default</item>
</string-array>
<string-array name="theme_values">
<item>light</item>
<item>dark</item>
<item>default1</item>
</string-array>
</resources>
My listpreference:
<ListPreference
android:id="#+id/list"
app:entries="#array/theme_entries"
app:entryValues="#array/theme_values"
app:key="theme"
app:title="#string/theme_title"
app:useSimpleSummaryProvider="true" />
And the app theme I'm using (styles.xml):
<style name="AppTheme2" parent="Theme.AppCompat.DayNight.DarkActionBar">
<!-- Customize your theme here. -->
<item name="android:forceDarkAllowed" tools:targetApi="q">true</item>
<item name="android:isLightTheme" tools:targetApi="q">true</item>
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#FFFFFF</item>
<item name="android:windowContentOverlay">#null</item>
<item name="android:backgroundDimEnabled">false</item>
</style>
Any suggestions?

In your styles.xml you should not take Theme.AppCompat.DayNight.DarkActionBar as a parent while you enabled forceDarkAllowed. Change that to Theme.AppCompat or Theme.MaterialComponents. You cannot inherit from a daynight theme while forceDarkAllowed is set to true. You can read about that here https://developer.android.com/guide/topics/ui/look-and-feel/darktheme section forcedark.

String theme = String.valueOf(listPreference.getEntry());
Should work fine, you just didn't declare theme as a string
:)

PreferenceFragmentCompat won't change color when change theme and recreate activity

I'm using PreferenceFragmentCompat for preferences and when I change theme preference using ListPreference to a dark theme and recreate activity text stays dark and becomes not visible. If I reopen this fragment text becomes white, but it returns to black color on orientation change
Here is my styles:
<style name="AppThemeLight" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="preferenceTheme">#style/preferenceLight</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowActionBar">false</item>
<item name="windowActionModeOverlay">true</item>
<item name="android:textColorPrimary">#color/primaryText</item>
<item name="android:textColorSecondary">#color/secondaryText</item>
</style>
<style name="AppThemeDark" parent="Theme.AppCompat.NoActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="preferenceTheme">#style/preferenceDark</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowActionBar">false</item>
<item name="windowActionModeOverlay">true</item>
<item name="android:windowBackground">#color/primaryText</item>
<item name="android:textColorPrimary">#color/primaryTextDark</item>
<item name="android:textColorSecondary">#color/secondaryText</item>
</style>
<style name="preferenceLight" parent="PreferenceThemeOverlay.v14.Material">
<item name="android:textColor">#color/primaryText</item>
<item name="android:textColorPrimary">#color/primaryText</item>
<item name="android:textColorSecondary">#color/secondaryText</item>
</style>
<style name="preferenceDark" parent="PreferenceThemeOverlay.v14.Material">
<item name="android:textColor">#color/primaryTextDark</item>
<item name="android:textColorPrimary">#color/primaryTextDark</item>
<item name="android:textColorSecondary">#color/secondaryText</item>
</style>
and fragment
class SettingsFragment : PreferenceFragmentCompat(), SharedPreferences.OnSharedPreferenceChangeListener{
private lateinit var advertisePreferences: AdvertisePreferences
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
advertisePreferences = AdvertisePreferences(context!!)
}
override fun onResume() {
super.onResume()
(activity as AppCompatActivity).supportActionBar?.title = getString(R.string.settings)
preferenceManager.sharedPreferences.registerOnSharedPreferenceChangeListener(this)
}
override fun onPause() {
super.onPause()
preferenceManager.sharedPreferences.unregisterOnSharedPreferenceChangeListener(this)
}
override fun onCreatePreferences(savedInstanceState: Bundle?, rootKey: String?) {
setPreferencesFromResource(R.xml.app_preferences, rootKey)
}
override fun onPreferenceTreeClick(preference: Preference): Boolean {
when(preference.key){
}
return super.onPreferenceTreeClick(preference)
}
override fun onSharedPreferenceChanged(sharedPreferences: SharedPreferences, key: String) {
when(key){
getString(R.string.theme_key) -> {
activity?.recreate()
}
}
}
}

It seems it was bug in library. It now fixed in androidx.preference:preference:1.1.0-alpha02
