Answer 1

Yes, you can add the custom toolbar to your fragment and make your activity theme with no action bar in the Manifest and do something like this. this layout may be your fragment layout and inflate in your activity.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:map="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?actionBarSize"
    android:layout_alignParentTop="true"
    android:background="@color/colorPrimary"
    android:gravity="top"
    app:titleTextColor="@color/white">

    <ImageView
        android:id="@+id/iv_home"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="left"
        android:contentDescription="TODO"
        android:visibility="visible"
        app:srcCompat="@drawable/ic_back" />

    <TextView
        android:id="@+id/toolbar_title"
        style="@style/TextAppearance.AppCompat.Widget.ActionBar.Title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="List Entry"
        android:textColor="@color/white"
        android:textSize="@dimen/large_text_size" />

    <ImageView
        android:id="@+id/iv_add"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:layout_margin="@dimen/middium_padding"
        android:contentDescription="TODO"

        android:src="@mipmap/add"
        android:visibility="visible" />

</android.support.v7.widget.Toolbar>


</RelativeLayout>

and access you toolbar with framgment view.
