Android Drawable Shape with 3 layer border

Hi I am trying to add a border to a view which has yellow border but it also has a black border on both sides of primary border.
Any ideas

Try this drawable layout for border on top and bottom
<?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="2dp"
android:color="#ffff00" />
<solid android:color="#000000" />
</shape>
</item>
<item
android:bottom="2dp"
android:top="2dp">
<shape android:shape="rectangle">
<stroke
android:width="2dp"
android:color="#000000" />
</shape>
</item>
</layer-list>
Try this for left and right border
<?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="#ffff00"/>
</shape>
</item>
<item android:left="4dp">
<shape android:shape="rectangle">
<solid android:color="#000000"/>
</shape>
</item>
<item android:right="4dp">
<shape android:shape="rectangle">
<solid android:color="#000000"/>
</shape>
</item>
</layer-list>

How to add a drop shadow to a Rectangular Shape in Android

I am developing an Android App in which I need to use a Rectangular shape which should have a drop_shadow. I have designed a rectangular shape but somehow i am not able to add a drop shadow to it on (right and left sides).
P.S.: this rectangular shape is added as a background attribute.
If this type of Question is already been answered then please provide the links here.
THANK YOU IN ADVANCE!!!!
Code:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ffffff" />
<stroke
android:width="1dp"
android:color="#000000" />
<corners
android:radius="10dp" >
</corners>
</shape>

Try this:
<?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="#CABBBBBB"/>
<corners android:radius="2dp" />
</shape>
</item>
<item
android:left="0dp"
android:right="1dp"
android:top="0dp"
android:bottom="2dp">
<shape android:shape="rectangle">
<solid android:color="#android:color/white"/>
<corners android:radius="1dp" />
</shape>
</item>
</layer-list>

Keep ripple within stroke

I'm trying to create a ripple background drawable for a Button with a stroke.
This is what I have so far:
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#336699">
<item>
<shape android:shape="rectangle">
<solid android:color="#998811" />
<stroke
android:width="2dp"
android:color="#119988" />
</shape>
</item>
</ripple>
But with this solution, the ripple overlaps with my stroke.
I only want the ripple within the stroke, How can I do this?

As per the documentation you add another item with id #android:id/mask - that will limit where the ripple goes. You can set that to be inset, like so:
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#336699">
<item>
<shape android:shape="rectangle">
<solid android:color="#998811" />
<stroke
android:width="2dp"
android:color="#119988" />
</shape>
</item>
<item android:id="#android:id/mask">
<inset android:insetBottom="2dp"
android:insetLeft="2dp"
android:insetRight="2dp"
android:insetTop="2dp">
<shape android:shape="rectangle">
<!-- Color doesn't matter -->
<solid android:color="#android:color/white"/>
</shape>
</inset>
</item>
</ripple>

how to add gradient effect in layout border xml file

this is my xml file which add border around linear layout how do i add gradient color effect code inthis code? i want replace this color #C0C0C0 with gradiend color
below is my code
<?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="#000000" />
</shape>
</item>
<item
android:left="1dp"
android:right="1dp"
android:top="2dp"
android:bottom="2dp" >
<shape android:shape="rectangle">
<solid android:color="#C0C0C0" />
</shape>
</item>
</layer-list>
i want to add this code in my border .xml file how i merge??
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#fefdfe"
android:endColor="#e8e3ec"
android:angle="90" />
</shape>

fill layout with gradient:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<gradient
android:startColor="#4fc939"
android:centerColor="#0c87c5"
android:endColor="#b4ec51"
android:angle="180" />
</shape>
</item>

Just replace
<shape android:shape="rectangle">
<solid android:color="#C0C0C0" />
</shape>
with your gradient shape.

Try this:-
<shape android:shape="rectangle">
<gradient
android:startColor="#5a5a5a88"
android:endColor="#14141488"
android:angle="270" android:centerX="0.25"/>
</shape>

Shape drawable as background, a line at the bottom

I am using a drawable as a background of a TextView just to have a divider line below the text. A achivied it with this drawable-xml:
<?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="#FFDDDDDD" />
<gradient
android:angle="0"
android:startColor="#FFAAAAAA"
android:endColor="#FFEEEEEE"
/>
</shape>
</item>
<item android:bottom="2dp">
<shape
android:shape="rectangle">
<solid android:color="#FF000000" />
</shape>
</item>
</layer-list>
But this method draws a colored rectangle above a black rectangle. I would like to have just the line at the bottom of the shape with no black rectangle because black is not transparent. How could I achieve that?

This is how I got a line at the bottom for mine. Draw a stroke but then shift the item up and to the sides to get the top and sides to not show the stroke:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="-8dp" android:left="-8dp" android:right="-8dp">
<shape>
<solid android:color="#2b7996"/>
<stroke android:color="#33b5e5" android:width="6dp"/>
</shape>
</item>
</layer-list>

I think it's better solution:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:gravity="bottom">
<shape>
<size android:height="1dp" />
<solid android:color="#000000" />
</shape>
</item>
</layer-list>

In general, I try to mess as little as possible with backgrounds unless absolutely necessary, since doing so overrides the default background colors that have states for focused, pressed, etc. I suggest just using an additional view (in a vertical LinearLayout) that is as thick as you need it to be. For example:
<View
android:background="#FF000000"
android:layout_height="2dp"
android:layout_width="fill_parent"/>

Usually for similar tasks - I created layer-list drawable like this one:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#color/underlineColor"/>
</shape>
</item>
<item android:bottom="3dp">
<shape android:shape="rectangle">
<solid android:color="#color/buttonColor"/>
</shape>
</item>
The idea is that first you draw the rectangle with underlineColor and then on top of this one you draw another rectangle with the actual buttonColor but applying bottomPadding. It always works.
But when I needed to have buttonColor to be transparent I couldn't use the above drawable. I found one more solution
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="#android:color/transparent"/>
</shape>
</item>
<item android:drawable="#drawable/white_box" android:gravity="bottom" android:height="2dp"/>
</layer-list>
(as you can see here the mainButtonColor is transparent and white_box is just a simple rectangle drawable with white Solid)

With this solution where ever you require different line you can. My requirement was underline only. Even you can give different colors to the layout. You can see in below picture, white line
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="-5dp" android:left="-5dp" android:right="-5dp">
<shape>
<solid android:color="#android:color/transparent"/>
<stroke android:color="#color/white" android:width="5dp"/>
</shape>
</item>
<item android:top="-5dp" android:bottom="-5dp" android:right="-5dp">
<shape>
<solid android:color="#android:color/transparent"/>
<stroke android:color="#color/colorPrimaryDark" android:width="5dp"/>
</shape>
</item>
<item android:bottom="-5dp" android:left="-5dp" android:right="-5dp">
<shape>
<solid android:color="#android:color/transparent"/>
<stroke android:color="#color/colorPrimaryDark" android:width="5dp"/>
</shape>
</item>
<item android:top="-5dp" android:left="-5dp" android:bottom="-5dp">
<shape>
<solid android:color="#android:color/transparent"/>
<stroke android:color="#color/colorPrimaryDark" android:width="5dp"/>
</shape>
</item>
<item android:bottom="2dp" android:left="5dp" android:right="5dp" android:top="5dp">
<shape>
<solid android:color="#color/colorPrimary"/>
<corners android:bottomRightRadius="0dp"
android:bottomLeftRadius="0dp"
android:topLeftRadius="0dp"
android:topRightRadius="0dp" />
</shape>
</item>
</layer-list>

This is a slightly lighter variant of the above.
/drawable/rect_highlight.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<stroke android:width="1px" android:color="#color/colorHighlight"/>
</shape>
/drawable/underline.xml
<inset xmlns:android="http://schemas.android.com/apk/res/android" android:insetLeft="-1px" android:insetRight="-1px" android:insetTop="-1px" android:drawable="#drawable/rect_highlight"/>
Usage:
<TextView ... android:background="#drawable/underline"/>
It's not mine, somebody smarter than I came up with it. If I was smarter, I would have asked who. :)

This solution worked for most of the cases that I needed something like that.
<?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="#android:color/transparent" /> <!--background color of box-->
</shape>
</item>
<item
android:height="2dp"
android:gravity="bottom">
<shape>
<solid android:color="#000000" />
</shape>
</item>
</layer-list>

A simple solution is extending a TextView, then override the onDraw.
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
Paint paint = new Paint();
paint.setColor(ContextCompat.getColor(getContext(),R.color.colorTextUnderLine));
paint.setStrokeWidth(10);
canvas.drawLine(0.0f,canvas.getHeight(),canvas.getWidth(),canvas.getHeight(),
paint);
}
