Placing button over two different LinearLayouts

So, I would like to add a button with the text "Already Registered?" on the middle bottom screen but my code contains a two different LinearLayouts for the half left and the half right side. I want the button to be half on the left Linearlayout and half on the right. In addition, they are clickable so as far as I concern I must have them in my current layout and not include them.

what I currently have:

Solution

  • There are other types of ViewGroup besides LinearLayout which allow you to achieve a "split screen" effect, but let's keep it simple and use a weighted LinearLayout to divide the screen.

    The child Views however can be TextViews (no intermediate ViewGroup required) because you can let them have a background color and also control the text alignment.

    Since you want the Button to overlap both parts of the screen, you can put it and the LinearLayout into a FrameLayout (I used a TextView but the attributes are basically the same):

    <FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:weightSum="2">
        <TextView
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="match_parent"
            android:text="Customer"
            android:textColor="#aaaaaa"
            android:textSize="20sp"
            android:gravity="center"
            android:background="#0000ff"/>
        <TextView
            android:layout_width="0dp"
            android:layout_weight="1"
            android:layout_height="match_parent"
            android:text="Electrician"
            android:textColor="#666666"
            android:textSize="20sp"
            android:gravity="center"
            android:background="#ffab00"/>
    </LinearLayout>
    <TextView android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal|bottom"
        android:layout_marginBottom="24dp"
        android:textColor="#ffffff"
        android:textSize="20sp"
        android:text="Already Registered?"/>
</FrameLayout>
