How to change Toolbar Navigation and Overflow Menu icons (appcompat v7)?

Question

I am having a hard time with v7 Toolbar. What was once a simple task for ActionBar, now seems overly complex. No matter what style I set, I cannot change either navigation icon (which opens a Drawer) or overflow menu icon (which opens a menu).

So I have a Toolbar

<android.support.v7.widget.Toolbar
    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="wrap_content"
    android:background="@color/ghex"
    android:minHeight="?attr/actionBarSize"
    app:theme="@style/ThemeOverlay.AppCompat.Light"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    >

I code it looks like this

//before in the code I do
mToolbar = (Toolbar) findViewById(R.id.toolbar);

private void initToolbar() {
    setSupportActionBar(mToolbar);
    getSupportActionBar().setDisplayShowTitleEnabled(false);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);
}

Now, I need to change the Drawable for those two icons.

How do I do this for compat v7 Toolbar? I guess I would need to change the arrow visible when the drawer is open (Android 5.0).

To change the navigation icon you can use:

Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar);
setSupportActionBar(toolbar);
toolbar.setNavigationIcon(R.drawable.my_icon);

To change the overflow icon you can use the method:

toolbar.setOverflowIcon(ContextCompat.getDrawable(this, R.drawable.ic_my_menu);

If you would like to change the color of the icons you can use:

with a Material Components Theme (with a MaterialToolbar for example):

<com.google.android.material.appbar.MaterialToolbar
    android:theme="@style/MyThemeOverlay_Toolbar"
    ...>

  <style name="MyThemeOverlay_Toolbar" parent="ThemeOverlay.MaterialComponents.Toolbar.Primary">
    <!-- color used by navigation icon and overflow icon -->
    <item name="colorOnPrimary">@color/myColor</item>
  </style>

With an AppCompat Theme:

<android.support.v7.widget.Toolbar
  app:theme="@style/ThemeToolbar" />


<style name="ThemeToolbar" parent="Theme.AppCompat.Light">

   <!-- navigation icon color -->
   <item name="colorControlNormal">@color/my_color</item>

    <!-- color of the menu overflow icon -->
    <item name="android:textColorSecondary">@color/my_color</item>
</style>

You can also change the overflow icon overriding in the app theme the actionOverflowButtonStyle attribute:

With a Material Components Theme:

<style name="AppTheme.Base" parent="Theme.MaterialComponents.DayNight">
    <item name="actionOverflowButtonStyle">@style/OverFlow</item>
</style>

<style name="OverFlow" parent="Widget.AppCompat.ActionButton.Overflow">
    <item name="srcCompat">@drawable/my_overflow_menu</item>
</style>

With an AppCompat theme:

<style name="AppTheme.Base" parent="Theme.AppCompat.Light">
    <item name="actionOverflowButtonStyle">@style/OverFlow</item>
</style>

<style name="OverFlow" parent="Widget.AppCompat.ActionButton.Overflow">
    <item name="srcCompat">@drawable/my_overflow_menu</item>
</style>
