<menu xmlns:android="schemas.android.com/apk/res/android"
      xmlns:app="schemas.android.com/apk/res-auto">
<item
    android:id="@+id/action_name"
    android:icon="@drawable/icon_home"

and

@Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                onBackPressed();
                return true;
            case R.id.action_name:
                //your code//
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
