Android app running on emulator not on real device

Android emulator is working when running the application but on a real device the app gets an error from the action bar. I am using android bumble bee and the device is a Samsung s21
I already have NoActionBar as well as windowNoTitle true and windowActionBar false
Here is my error

I'm going to take a wild stab in the dark here and assume that you are using dark mode (night mode) on your device, but normal (day mode) on the emulator. Am I right??
See some of the answers in this related question: This Activity already has an action bar supplied by the window decor?

change androidx.appcompat.widget.SearchView (Search Icon within Action Bar) for androidx.legacy:legacy-support-v4:1.0.0 using material design

I am stuck on this for days.. I decided to add a bottom navigation, which forced me to change my design to material design. (https://material.io/components/bottom-navigation/android). Several style changes are now messing with my Action Bar. To be more precise, the androidx.appcompat.widget.SearchView of it. As seen in the picture below the search icon is black, I need it to be white.
I have tried a lot of solutions for similar problems answered here, but none seemed to do the trick. My current situation is the following:
I have this menu:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
android:theme="#style/MyActionBarTheme"
xmlns:app="http://schemas.android.com/apk/res-auto">
<!-- "toolbar top right hand items"-->
<item
android:id="#+id/activityExecutionsMenu_search"
android:icon="#drawable/ic_search_white"
android:title="#string/activityExecutionsFragments_menu_search_hint"
app:actionViewClass="androidx.appcompat.widget.SearchView"
app:showAsAction="always" />
<item
android:id="#+id/activityExecutionsMenu_group"
android:icon="#drawable/ic_group"
android:title="#string/activityExecutionsFragments_menu_group"

android:icon="#drawable/ic_filter"
android:title="#string/activityExecutionsFragments_menu_filter"

<item
android:id="#+id/activityExecutionsMenu_sort"
android:icon="#drawable/ic_sort"
android:title="#string/activityExecutionsFragments_menu_filter"

This is the Fragment, that gets reused in several parts of my app which creates the menu, including the onCreateOptionsMenu, in which some other promising attempts of SO answers seemed to get the job done, but do not work for me

frag.setArguments(args);
return frag;
}
#Override

public void onPrepareOptionsMenu(Menu menu) {

toolbar_filterButton = menu.findItem(R.id.activityExecutionsMenu_filter);
toolbar_sortButton = menu.findItem(R.id.activityExecutionsMenu_sort);
}
}
And these are some dependencies used in my gradle file
implementation "androidx.work:work-runtime:2.5.0"
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
testImplementation 'junit:junit:4.12'
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.google.android.material:material:1.2.1'
implementation 'com.google.firebase:firebase-appindexing:19.1.0'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'com.googlecode.mp4parser:isoparser:1.1.21'
implementation 'com.github.bumptech.glide:glide:4.9.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
implementation 'androidx.palette:palette:1.0.0'
How do I manage to get the search icon to be white again?
Should I remove the legacy.support library? Are there too many corresponding dependencies? Is it an issue extending DialogFragment?

Customizing a DialogFragment

The first image is what I want. The second is what I get
I've this class to create a dialog

import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.widget.Toast;
public class AlertFragment extends DialogFragment {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
return new AlertDialog.Builder(getActivity())
// Set Dialog Icon
.setIcon(R.drawable.androidhappy)
// Set Dialog Title
.setTitle("Alert DialogFragment")
// Set Dialog Message
.setMessage("Alert DialogFragment Tutorial")
// Positive button
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.cancel();
}
})
// Negative Button
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Do something else
}
}).create();
}
}

.......
AlertFragment alertdFragment = new AlertFragment();
// Show Alert DialogFragment
alertdFragment.setStyle(DialogFragment.STYLE_NORMAL, R.style.MyDialogFragmentStyle);
alertdFragment.show(fm, "Alert Dialog Fragment");
This is my style file

<item name="android:windowActionBar">false</item>
<item name="android:windowNoTitle">false</item>
<item name="android:headerDividersEnabled">true</item>
</style>
</resources>
I've posted all the style to see if there's anything going wrong. Regardless that I would like the separator between the header and the body of the dialog I do not understand why the buttons do not appear.
Edit:
I read this
Missing buttons on AlertDialog | Android 7.0 (Nexus 5x)
and I realized that i need to define a style for my dialog.
Infact if i set this
<style name="AlertDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="windowActionBar">true</item>
<item name="windowNoTitle">false</item>
<item name="android:buttonBarStyle">#style/Widget.AppCompat.ActionButton</item>
</style>
and then initialize dialog in this way
AlertDialog.Builder builder = new AlertDialog.Builder(SettingActivity.this,R.style.dialog_theme);
I can see change of color and text. But wich is property to show title, separator and buttons?

if you want a customized layout. You need to create an instance of Dialog. i.e. Dialog dialog = new Dialog; and set the contentview for that dialog: dialog.setContentView(R.layout.my_customized_dialog_layout);
you can then create buttons inside that layout and initialize them.

onClick event of button not working android

I'm trying to implement Guillotine Menu by yalantis in my app.
I've put one button in the guillotine activity and have made a class for the guillotine activity. In that class I'm trying to implement the listener for the button .I've also a put a toast in that function but that's not getting displayed either.

Define TabLayout style in theme

I have two different styles of TabLayout in my app:
<style name="TabLayoutPower" parent="Widget.Design.TabLayout">
<item name="tabSelectedTextColor">#android:color/white</item>
<item name="tabTextColor">#android:color/white</item>
</style>
<style name="TabLayoutFree" parent="Widget.Design.TabLayout">
<item name="tabSelectedTextColor">#android:color/black</item>
<item name="tabTextColor">#android:color/black</item>
</style>
How can I define the default TabLayout style for a theme? I cannot find any info which item name should I use to build my theme. I'd like to add the TabLayout the same way I added my listview:
<style name="Free" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/black</item>
<item name="colorPrimaryDark">#color/black</item>
<item name="colorAccent">#color/main_red</item>
<item name="android:windowBackground">#color/main_bg_light</item>
<item name="android:listViewStyle">#style/MyListView</item>
</style>

For Support Library TabLayout, you can set tabStyle attribute in your theme:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- ... -->
<item name="tabStyle">#style/AppTheme.TabLayout</item>
</style>
<style name="AppTheme.TabLayout" parent="Widget.Design.TabLayout">
<item name="tabSelectedTextColor">#android:color/white</item>
<item name="tabTextColor">#android:color/white</item>
</style>

If you wan to use 2 different styles for your TabLayout based on theme of your application then you should define your style inside attrs.xml
here is the Sample code for that
First you create an attrs.xml file ( Like this )
<?xml version="1.0" encoding="utf-8"?>
<resources>
<attr name="textColor" format="reference|color" />
<attr name="backColor" format="reference|color" />
<attr name="myTabStyle" format="reference" />
</resources>
define various theme as per your requirements inside styles.xml
Note: i have used 3 different themes for demo
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="tabStyle">#style/TabLayoutPower</item>
<item name="textColor">#android:color/white</item>
<item name="backColor">#color/colorPrimary</item>
</style>
<style name="AppTheme2" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#android:color/holo_green_dark</item>
<item name="colorPrimaryDark">#android:color/white</item>
<item name="colorAccent">#android:color/holo_blue_dark</item>
<item name="textColor">#android:color/white</item>
<item name="tabStyle">#style/TabLayoutFree</item>
<item name="backColor">#FF00</item>
</style>
<style name="AppTheme3" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#ff00</item>
<item name="colorPrimaryDark">#ff0</item>
<item name="colorAccent">#0a91d4</item>
<item name="tabStyle">#style/TabLayoutNew</item>
<item name="textColor">#FF00</item>
<item name="backColor">#android:color/white</item>
</style>
<style name="TabLayoutPower" parent="Widget.Design.TabLayout">
<item name="tabSelectedTextColor">#android:color/white</item>
<item name="tabTextColor">#android:color/white</item>
</style>
<style name="TabLayoutFree" parent="Widget.Design.TabLayout">
<item name="tabSelectedTextColor">#android:color/holo_blue_bright</item>
<item name="tabTextColor">#android:color/holo_blue_bright</item>
</style>
<style name="TabLayoutNew" parent="Widget.Design.TabLayout">
<item name="tabSelectedTextColor">#android:color/holo_green_dark</item>
<item name="tabTextColor">#android:color/holo_green_dark</item>
</style>
</resources>
Now use this style in your TabLayout like this inside layout.xml files
Use like this style="?myTabStyle" it will select style based on current theme of your application
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="#+id/btnThemeOne"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Theme One" />
<Button
android:id="#+id/btnThemeTwo"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Theme Two" />
<Button
android:id="#+id/btnThemeThree"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Theme Three" />
</LinearLayout>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
style="?myTabStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
android:background="#color/colorAccent"
app:tabMode="fixed" />
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</LinearLayout>

}
PrefManager class to save theme info
import android.content.Context;
import android.content.SharedPreferences;
public class PrefManager {
// Shared preferences file name
private final String PREF_NAME = "theme-pref";
private final String THEME = "theme";
SharedPreferences pref;
SharedPreferences.Editor editor;
public PrefManager(Context context) {
pref = context.getSharedPreferences(PREF_NAME, 0);
editor = pref.edit();
}
public int getTheme() {
return pref.getInt(THEME, R.style.AppTheme);
}
public void setTheme(int themeId) {
editor.putInt(THEME, themeId);
editor.commit();
}
}
you can check the output video of above code

You can find that name in Android theme -
<item name="android:tabWidgetStyle">#style/Your.Style</item>

<style name="Base.Widget.Design.TabLayout" parent="">
<item name="tabSelectedTextColor">#android:color/white</item>
<item name="tabTextColor">#android:color/white</item>
</style>
<style name="Free" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/black</item>
<item name="colorPrimaryDark">#color/black</item>
<item name="colorAccent">#color/main_red</item>
<item name="android:windowBackground">#color/main_bg_light</item>
