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>

Try some thing like this.
