Android Button Style Background with XML

Question

So I have two button styled pretty close to what i want but i need a little help getting it all the way. What I currently have is the first screen show, what I want is the second. Anyone have any ideas? I've attached the relevant code.

layout xml:

....
<Button
            android:id="@+id/sched_button"
            style="?android:attr/buttonBarButtonStyle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBottom="@+id/sync"
            android:layout_alignParentTop="true"
            android:background="@drawable/round_left_corner_active"
            android:text="@string/headersched"
            android:layout_toLeftOf="@+id/placeholder"
            android:paddingRight="@dimen/scheduleheadermargin"
            android:paddingLeft="@dimen/scheduleheadermargin" />

        <Button
            android:id="@+id/sched_fav_button"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBottom="@+id/sched_button"
            android:layout_alignParentTop="true"
            android:layout_toRightOf="@+id/placeholder"
            android:background="@drawable/round_right_corner"
            android:paddingLeft="@dimen/scheduleheadermargin"
            android:paddingRight="@dimen/scheduleheadermargin"
            android:text="@string/headerfav" />
...

round_left_corner_active:

<?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item>
        <shape android:shape="rectangle" >
            <solid android:color="@color/active" />

            <padding
                android:bottom="2dp"
                android:left="2dp"
                android:top="2dp" />

            <corners android:radius="5dp" />
        </shape>
    </item>
    <item>
        <shape android:shape="rectangle" >
            <padding
                android:bottom="5dp"
                android:left="5dp"
                android:right="5dp"
                android:top="5dp" />

            <solid android:color="@color/active" />
        </shape>
    </item>
</layer-list>

round_right_corner

<?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

    <item>
        <shape android:shape="rectangle" >
            <solid android:color="@color/active" />

            <padding
                android:bottom="2dp"
                android:right="2dp"
                android:top="2dp" />

            <corners android:radius="5dp" />
        </shape>
    </item>
    <item>
        <shape android:shape="rectangle" >
            <padding
                android:bottom="5dp"
                android:left="5dp"
                android:right="5dp"
                android:top="5dp" />

            <solid android:color="@color/base" />
        </shape>
    </item>
</layer-list>

Answer 1

For the left button:

<corners
    android:radius="5dip"
    android:topRightRadius="0dip"
    android:bottomRightRadius="0dip" />  

And the right one:

<corners
    android:radius="5dip"
    android:topLeftRadius="0dip"
    android:bottomLeftRadius="0dip" />  

This should do the trick.

However, android:bottomRightRadius and android:bottomLeftRadius have a bug in API lower than 12 (Android 3.1 Honeycomb). You should set the radius inside dimens.xml and create a new folder values-v12. See this solution: Something's wrong in Corner radius.
Then, you should do:

drawable button left

... 
<corners
    android:radius="5dip"
    android:topRightRadius="0dip"
    android:bottomRightRadius="@dimen/right_bottom_leftbutton"
    android:bottomLeftRadius="@dimen/left_bottom_leftbutton" /> 

drawable button right

... 
<corners
    android:radius="5dip"
    android:topLeftRadius="0dip"
    android:bottomRightRadius="@dimen/right_bottom_rightbutton"
    android:bottomLeftRadius="@dimen/left_bottom_rightbutton" /> 

values/dimens.xml

<!-- left button -->
<dimen name="right_bottom_leftbutton">5dip</dimen>
<dimen name="left_bottom_leftbutton">0dip</dimen>
<!-- right button -->
<dimen name="right_bottom_rightbutton">5dip</dimen>
<dimen name="left_bottom_rightbutton">0dip</dimen>

values-v12/dimens.xml

<!-- left button -->
<dimen name="right_bottom_leftbutton">0dip</dimen>
<dimen name="left_bottom_leftbutton">5dip</dimen>
<!-- right button -->
<dimen name="right_bottom_rightbutton">5dip</dimen>
<dimen name="left_bottom_rightbutton">0dip</dimen>
