Android – how do I change the text size of dialog preferences messages?

I have a class that extends edittextpreference. I use it in my own layout, for example:

    <com.app.MyEditTextPreference
        android:key="@string/key"
        android:title="@string/title"
        android:summary="@string/summary"
        android:dialogTitle="@string/title"
        android:dialogMessage="@string/message"
        android:layout="@layout/preference_edittext"/>

My app theme inherits from theme.appcompat.light.darkactionbar. I changed the value of text size:

<style name="TextAppearance.Small">
    <item name="android:textSize">18sp</item> <!-- was 14sp -->
</style>

However, when the preferences dialog box is displayed, the size of the message is different from the size I defined in my style

So how to correctly set the text size of dialog messages?

edit

I copied the dialog layout from the SDK:

<LinearLayout
    android:id="@+android:id/edittext_container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="20dp"
    android:orientation="vertical">

    <TextView
        android:id="@android:id/message"
        android:layout_marginBottom="48dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingStart="4dp"
        android:paddingEnd="4dp"
        android:textColor="?android:attr/textColorSecondary"
        style="@style/TextAppearance.Small" />

</LinearLayout>

However, I got a build error resource that is not public Android: id = "@ Android: ID / edittext_container"

If I change it to "@ * Android: ID / edittext_container", the edited text will no longer be visible

Is there a simpler way to change the text size of a message?

resolvent:

First, create a new XML file named cus. XML in the layout folder. It needs to set the view of the dialog box at run time

<?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<TextView
    android:id="@+id/textView2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Enter Name :"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:textSize="18dp" />


<EditText
    android:id="@+id/editText"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:textSize="18dp" />

<Button
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="New Button"
    android:textSize="18dp" />

When you need a dialog: This is the dialog code:

Dialog d=new Dialog(getActivity());
                d.setTitle("Image Title");
                d.setContentView(R.layout.cus);
                d.show();
