Bottom Rounded Corners - Android

I have been trying to fix this but for whatever I do, I just cannot get the Bottom Rounded Corners the way I want, I am using the following
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle">
<stroke android:width="0dp" />
<solid android:color="?attr/colorPrimaryDark" />
</shape>
</item>
<item android:top="0dp" android:bottom="1dp">
<shape
android:shape="rectangle">
<stroke android:width="0dp"/>
<solid android:color="?attr/colorPrimary"/>
<corners android:radius="15dp" android:bottomRightRadius="15dp" android:bottomLeftRadius="15dp" android:topLeftRadius="0dp" android:topRightRadius="0dp"/>
</shape>
</item>
</layer-list>
The Results are the following
It creates the corners but it adds grey color (colorPrimaryDark) to it where I want it to be white (colorPrimary") with a grey line - Any idea how I accomplish this?

A little hack is possible to get rid of line on top and sides: set negative offsets.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:left="-1dp"
android:right="-1dp"
android:top="-1dp">
<shape android:shape="rectangle">
<stroke
android:width="1dp"
android:color="?attr/colorPrimaryDark" />
<solid android:color="?attr/colorPrimary" />
<corners
android:bottomLeftRadius="15dp"
android:bottomRightRadius="15dp"
android:radius="15dp"
android:topLeftRadius="0dp"
android:topRightRadius="0dp" />
</shape>
</item>
</layer-list>
Not sure will it work correctly on all devices / Android versions or not.

If you only want bottom border a Shape drawable will be enough . You do not need a layer-list for it .
try this
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="1dp" android:color="#color/green"/>
<solid android:color="?attr/colorPrimary" />
<corners
android:bottomLeftRadius="15dp"
android:bottomRightRadius="15dp" />
</shape>
The problem with your current code is first item have a solid color set . this is why the gray part showing .

THANK YOU IN ADVANCE!!!!
Code:
<?xml version="1.0" encoding="utf-8"?>

<solid android:color="#ffffff" />
<stroke
android:width="1dp"
android:color="#000000" />

<item>
<shape android:shape="rectangle">
<solid android:color="#CABBBBBB"/>

How to make bottom border in drawable shape XML selector?

I'm trying to create a drawable shape with different states for my button. So I wrote this:
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" android:color="#android:color/black" >
<shape android:shape="rectangle" >
<solid android:color="#color/NEGATIVE_pressed" />
<stroke
android:width="1dp"
android:color="#color/ORANGE" />
<corners android:radius="4dp" />
</shape>
</item>
<item android:state_focused="true" android:color="#android:color/black" >
<shape android:shape="rectangle" >
<solid android:color="#color/NEGATIVE_focused" />
<stroke
android:width="1dp"
android:color="#color/ORANGE" />
<corners android:radius="4dp" />
</shape>
</item>
<item android:color="#android:color/black" >
<shape android:shape="rectangle" >
<solid android:color="#color/NEGATIVE" />
<stroke
android:width="1dp"
android:color="#color/NEGATIVE" />
<corners android:radius="4dp" />
</shape>
</item>
</selector>
Then in my button I use it as android:background="#drawable/btn_negative_selector"
However, I want to draw a bottom border to that shape, to be, something like 3 dp and of different color, but I can't figure out how to do it. I tried searching, but didn't find anything suitable for selector. Any suggestions, please?

First I'm separating the shapes to make them easier to manage.
This is your btn_negative_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#xml/rectangle_button_pressed" android:state_pressed="true"></item>
<item android:drawable="#xml/rectangle_button_focused" android:state_focused="true"></item>
<item android:drawable="#xml/rectangle_button" ></item>
</selector>
create folder called 'xml' in your res and save these shapes into it:
1) rectangle_button_pressed:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#color/NEGATIVE_pressed" />
<stroke
android:width="1dp"
android:color="#color/ORANGE" />
<corners android:radius="4dp" />
</shape>
2) rectangle_button_focused:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#color/NEGATIVE_focused" />
<stroke
android:width="1dp"
android:color="#color/ORANGE" />
<corners android:radius="4dp" />
</shape>
3) This one rectangle_button.xml will have a border at the bottom of it by defining a shape using <layer-list>. first <item> is bottom layer and last <item> is the top layer.
<?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/gray"/>
<corners android:radius="4dp"/>
</shape>
</item>
<item android:bottom="3dp">
<shape android:shape="rectangle">
<solid android:color="#color/orange" />
<corners android:radius="4dp"/>
</shape>
</item>
</layer-list>

Create Drawable with borders completely programmatically

I have the following xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape
android:shape="rectangle">
<stroke android:width="1dp" android:color="#000000" />
<solid android:color="#000000" />
</shape>
</item>
<item android:top="0dp" android:bottom="1dp">
<shape
android:shape="rectangle">
<stroke android:width="1dp" android:color="#414141" />
<solid android:color="#414141" />
</shape>
</item>
<item android:top="1dp" android:bottom="1dp">
<shape
android:shape="rectangle">
<stroke android:width="1dp" android:color="#2C2C2C" />
<solid android:color="#2C2C2C" />
</shape>
</item>
</layer-list>
This does exactly what I want but I can't use it. I want to change the colors of the three layers on runtime so I have to do this completely programmatically. I know I have to use LayerDrawable but I don't know how to implement the equivalent of android:top and android:bottom. Can somebody help me?

ImageView imageView1 = (ImageView) findViewById(R.id.imgView1);
((GradientDrawable ) imageView1.getBackground()).setColorFilter(
Color.RED, PorterDuff.Mode.SRC_ATOP);
