Actually I have this screen on the activity in my android app.
I wish to add an image to the left side of the text "Stone" on the top left corner which is contained in the default action bar of the app (which is the default theme).
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".LoginActivity">
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="64dp"
android:gravity="center_horizontal"
android:text="Stone Login"
android:textSize="36sp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<EditText
android:id="@+id/unameTxt"
android:layout_width="358dp"
android:layout_height="41dp"
android:layout_marginTop="52dp"
android:ems="10"
android:hint="User id"
android:inputType="textPersonName"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.501"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/textView2" />
<EditText
android:id="@+id/passwdTxt"
android:layout_width="359dp"
android:layout_height="42dp"
android:layout_marginTop="36dp"
android:ems="10"
android:hint="@string/prompt_password"
android:inputType="textPassword"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/unameTxt" />
<Button
android:id="@+id/loginButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="52dp"
android:text="Accedi"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/passwdTxt" />
</android.support.constraint.ConstraintLayout>
On the top, there is the activity layout XML file.
This is my styles.xml file:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>
I've tried many solutions but nothing has worked and I wish to change the actionbar for all the activities in the app.
Could you help me in doing this, please?
Kindly, Roberto

In order to display a custom drawable in your ActionBar you should add these lines:
supportActionBar?.setDisplayShowHomeEnabled(true)
supportActionBar?.setIcon(R.drawable.your_icon)
Here's an article about ActionBar https://guides.codepath.com/android/Defining-The-ActionBar
