[android]how to get 4 buttons at the bottom and each 2 button is beside each other

问题

I find majority teaching online is about 2 button beside each other but I couldnt obtain the arrangement wanted as in the image. When I put in the relativelayout, all the button overlap together no matter I put android:layout_above:"XX" All my total, 0.00, back and pay button , i need to out them at the bottom. this is my original code:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<TextView
    android:id="@+id/billTV"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TextView" />

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="bottom"
    android:orientation="horizontal" >

    <Button
        android:id="@+id/backB"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Back" />

    <Button
        android:id="@+id/payB"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:text="Pay" />
</LinearLayout>
