Customizing a Preference Alert Dialog for an EditTextPreference in Android

 In your themes.xml, add the following:

<resources xmlns:android="http://schemas.android.com/apk/res/android">

  <style name="Theme.Your_Theme" parent="Theme.MaterialComponents.DayNight.NoActionBar" android:forceDarkAllowed="true">

[...]

    <item name="alertDialogTheme">@style/YourAlertDialogTheme</item>
  </style>

 </resources>

In the styles.xml, add the style for the dialog itself:

 <style name="YourAlertDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
   <!-- Changes the dialog background color -->
   <item name="android:windowBackground">@color/light_grey</item>
   <!-- Changes the title and message text color -->
   <item name="android:textColorPrimary">@color/alert_dialog_button_txt</item>
   <!-- If using Material Components, use this for buttons -->
   <!--<item name="buttonBarPositiveButtonStyle">@style/Widget.MaterialComponents.Button.TextButton</item>-->
   <item name="buttonBarPositiveButtonStyle">@style/Widget.Your.Button.TextButton</item>
   <item name="buttonBarNegativeButtonStyle">@style/Widget.Your.Button.TextButton</item>
 </style>

 <style name="Widget.Your.Button.TextButton" parent="Widget.MaterialComponents.Button.TextButton">
   <!-- Changes the text and icon color -->
   <item name="android:textColor">@color/alert_dialog_button_txt</item>
   <!--<item name="iconTint">@color/red_status</item>-->
   <!-- Changes the click ripple color -->
   <!--<item name="rippleColor">@color/green_dark</item>-->
 </style>

In your your_preferences.xml, add:

<PreferenceScreen xmlns:app="http://schemas.android.com/apk/res-auto">

  <EditTextPreference
    app:key="pk_quality_threshold"
    app:title="@string/title_quality_threshold"
    app:dialogTitle="@string/title_quality_threshold"
    app:summary="@string/leak_quality_threshold_summary"
    app:defaultValue="40"
    app:dialogLayout="@layout/pref_edittext" />

Then define the custom layout for the EditTextPreference to change the color of the edit text background, text and cursor:

pref_edittext.xml

<?xml version="1.0" encoding="utf-8"?>

<!-- Used in ui_preferences.xml -->

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="8dp"
    android:orientation="vertical">

    <!-- If you use: android:textCursorDrawable="@null"
    the cursor will automatically inherit the color defined in
    the android:textColor property -->
    <EditText
        android:id="@android:id/edit"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textColor="@color/alert_dialog_button_txt"
        android:background="@color/white"
        android:textCursorDrawable="@null"
        android:padding="8dp" />

</LinearLayout>

Done!
 

Windows Cleanup Tips

 [1] The safest way is to let Windows do it

Go to Settings -> System -> Storage -> Temporary Files.

Select everything and click on Remove files. 

 [2] Use an external tool

 Example: PatchCleaner.

[3] Delete old files from the temporary directory

This directory is usually located in: C:\Users\<YOUR_USERNAME>\AppData\Local.

Here you can safely delete months or years old files. If they're still in use, Windows will prevent you from deleting them. 

If you're in doubt, skip what you were planning to do.
