Android XML background circle in corners - android

I want to define a backgound image using XML. Like 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="#C0C0C0" />
<corners android:radius="5dp"/>
</shape>
</item>
<item android:right="1dp" android:left="1dp" android:bottom="3dp">
<shape
android:shape="rectangle">
<solid android:color="#FFFFFF"/>
<corners android:radius="5dp"/>
</shape>
</item>
</layer-list>
For some visual reasons, I want to draw circles in each corner of this background with XML.
Is there a possibility to do so? For example like this:


You can use RoundedImageView class,
compile 'com.makeramen:roundedimageview:2.3.0'

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>

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);
}
