Floating Action Button in linearLayout

Question

How can i add FAB into the second linearLayout named layout_ejercicios?

If i add this like that it doesnt appear.

I want add the FAB in the layout_ejercicios at right bottom corner.

I try to include the FAB out of the layout_ejercicios but it appears always in the top left corner.

Answer 1

1. Remove FAB from inside the Linear Layout layout_ejercicios
2. Add FAB to Relative layout activity_crear_entrenamiento and set with android:layout_alignRight="@+id/layout_ejercicios" and android:layout_alignBottom="@+id/layout_ejercicios"

Like this

<RelativeLayout
    android:id="@+id/activity_crear_entrenamiento"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <include
        android:id="@+id/tool_bar"
        layout="@layout/toolbar" />

    <LinearLayout
        android:id="@+id/layout_ejercicios"
        android:layout_width="match_parent"
        android:layout_height="300dp"
        android:layout_alignParentStart="true"
        android:layout_below="@+id/layout_info">

        <include
            android:id="@+id/tool_bar_ejercicios"
            layout="@layout/toolbar" />

    </LinearLayout>

    <android.support.design.widget.FloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/layout_ejercicios"
        android:layout_alignRight="@+id/layout_ejercicios"
        android:layout_margin="16dp"
        android:src="@drawable/ic_action_name"
        app:layout_anchor="@id/layout_ejercicios"
        app:layout_anchorGravity="bottom|right|end" />

</RelativeLayout>
