Question

I'm making an Android app that have one activity and multiple fragments and a NavigationDrawer. Now all the fragments have the same toolbar, but i want a different toolbar for each fragment and i don't find the best method to do it. I read some tutorials but each person make it in a different way and I want to do the best solution Can someone explain me the best way to do this (it is no necessary to write the code, only the idea)

Answer 1

My opinion is to use Toolbar as part of each fragment layout. That way you would have the possibility to customize it the way you need it. If there is something common about every screen you can make a custom toolbar and include it in every layout.

Example:

<LinearLayout
        android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/background_gray"
        android:orientation="vertical">

        <include layout="@layout/back_button_toolbar" />
 
        <!-- Your layout here... -->
</LinearLayout>

And the back button toolbar may be customizable as you like. Something like this:

<androidx.appcompat.widget.Toolbar 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/back_toolbar"
    android:layout_width="match_parent"
    android:layout_height="@dimen/top_bar_height"
    android:background="@color/whitelabel_topbar_color"
    app:navigationIcon="@drawable/ic_navigate_back">

    <TextView
        android:id="@+id/toolbar_title"
        style="@style/ToolbarTitle"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:gravity="center" />

</androidx.appcompat.widget.Toolbar>
