After the new Support library v22.1, you can use something similar to this:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_home, menu);
Drawable drawable = menu.findItem(R.id.action_clear).getIcon();
drawable = DrawableCompat.wrap(drawable);
DrawableCompat.setTint(drawable, ContextCompat.getColor(this,R.color.textColorPrimary));
menu.findItem(R.id.action_clear).setIcon(drawable);
return true;
}
