Answer 1

@Override
        public boolean onCreateOptionsMenu(Menu menu) {
            getMenuInflater().inflate(R.menu.menu_notifications, menu);
            this.menu = menu;
            super.onCreateOptionsMenu(menu);
            return true;
        }

        @Override
        public boolean onOptionsItemSelected(MenuItem item) {
            int id = item.getItemId();
            if (id == R.id.action_clear_all) {
                showToast("Clear All");
                return true;
            }
            return super.onOptionsItemSelected(item);
        }

Create xml file under res>menu.

<menu 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"
    tools:context=".YourActivityName" >

    <item
        android:id="@+id/action_clear_all"
        android:title="@string/noti_clear_all"
        android:icon="@drawable/ic_clear_all"
        android:orderInCategory="100"
        app:showAsAction="ifRoom" />

</menu>

Answer 2

You can reset the color of your MenuItem by setColorFilter .

Drawable can be changed to any color.

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.menu_menu_frag, menu);
    // replace MenuItem with your own
    MenuItem item = menu.getItem(0);
    final Drawable drawable = item.getIcon();
    if (drawable != null) {
        final int color = Color.RED;
        drawable.setColorFilter(new PorterDuffColorFilter(color, PorterDuff.Mode.SRC_IN));
    }
}

Answer 3

In onCreateOptionsMenu(Menu menu, MenuInflater inflater) you can use this:
Note: You may want to use PorterDuff.Mode.SRC_IN instead of PorterDuff.Mode.MULTIPLY )

MenuItem searchItem = menu.findItem(R.id.action_search);
int color = 0; // SPECIFY THE COLOUR YOU WANT HERE. I suggest you retrieve colour from colors.xml
menuItem.getIcon().setColorFilter(color, PorterDuff.Mode.MULTIPLY);

But personally I would probably just change the colour of the drawable manually (ie replace the drawable with a coloured one).

Use below XML in your menu item

<item
        android:id="@+id/menu_search"
        android:actionViewClass="android.widget.SearchView"
        android:icon="@drawable/search"
        android:showAsAction="ifRoom|collapseActionView"
        android:title="@string/menu_search" />

// Please make sure you using same menu item xml in your activity or fragment.
