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

For right menu you can do it:

public static Drawable setTintDrawable(Drawable drawable, @ColorInt int color) {
            drawable.clearColorFilter();
            drawable.setColorFilter(color, PorterDuff.Mode.SRC_IN);
            drawable.invalidateSelf();
            Drawable wrapDrawable = DrawableCompat.wrap(drawable).mutate();
            DrawableCompat.setTint(wrapDrawable, color);
            return wrapDrawable;
        }

And in your activity

@Override
 public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.menu_profile, menu);
        Drawable send = menu.findItem(R.id.send);
        Drawable msg = menu.findItem(R.id.message);
        DrawableUtils.setTintDrawable(send.getIcon(), Color.WHITE);
        DrawableUtils.setTintDrawable(msg.getIcon(), Color.WHITE);
        return true;
    }

This is the result:

There is a simple, easy and better approach, if we need to change only the color of hamburger/back icon.

It is better as it changes color only of desired icon, whereas colorControlNormal and android:textColorSecondary might affect other childviews of toolbar as well.

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

<style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="spinBars">true</item>
    <item name="color">@android:color/white</item>
</style>

mToolbar.setNavigationIcon(R.mipmap.ic_launcher);
mToolbar.setOverflowIcon(ContextCompat.getDrawable(this, R.drawable.ic_menu));

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>
