ImageView: How to draw a grey circle in front of a icon? - android

As you can see on the screenshots, I have a icon on the left side of this.
How can I draw a grey circle on the front of that left icon in the layout xml, as in following screenshot?
Screenshot

You can try this;
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<solid android:color="#BCBCBC" />
</shape>
</item>
<item android:top="1dp" android:left="1dp" android:right="1dp" android:bottom="1dp" android:drawable="#drawable/your_cross_icon">
<shape android:shape="oval">
<solid android:color="#BCBCBC" />
</shape>
</item>
</layer-list>

create this drawable
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid
android:color="#666"/>
</shape>
then put it as background of the image view, and put the X as the src of imageview
The circle is the drawable that is behind the image.
This way you can reutilize the drawable and put in several icons

How to make curved edge in a rectangle shape in android

Am trying to achieve this without using image as background, wanted to be done in xlm drawable
Use this
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#FFFFFF" />
</shape>
</item>
<item
android:bottom="0dp"

android:right="-200dp"

<shape
android:shape="oval">
<solid android:color="#color/dark_orange" />
</shape>
</item>
Change left-right margin as per your requirements. That will change curve.

Shape with multiple circles

I want to draw a circle of color 1 inside a circle of color 2. Both of them have stroke and its inside is transparent. This should be used as a background of a button.
Something like this (but green and red are next to each other - no gap in between. Sorry, I don't have any graphical program where I could draw them so they're next to each other.)
Is there a way how to do it in XML ?
I was thinking of doing it using shape XML but layers are scaled so layers would be on top of each other so only 1 color would be visible.
You use a layer list with insets in order to avoid the inner circle to lurk out from the outer circle, like this:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<stroke
android:width="4dp"
android:color="#android:color/holo_red_dark" />
</shape>
</item>
<item>
<inset android:inset="4dp">
<shape android:shape="oval">
<stroke
android:width="4dp"
android:color="#android:color/holo_green_dark" />
</shape>
</inset>
</item>
</layer-list>
You set the size and background of the button like this:
<Button
android:id="#+id/button"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#drawable/red_green" />
It then looks like this:
Try something like this:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<size android:height="10dp" android:width="10dp"/>
<stroke
android:width="2dp"
android:color="#FF0000"
/>
</shape>
</item>
<item>
<shape android:shape="oval">
<stroke
android:width="1dp"
android:color="#00FF00"
/>
</shape>
</item>
</layer-list>
You can change the width and height of the size element to get a different ring width.
You can achieve this by defining two drawable resources both circle with different stroke colors and puting them in a layer-list drawable one on top of the other, with different ofsets which give then the effect you need:
Inner circle inner.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<stroke android:color="#color/colorRed"
android:width="2dp"/>
</shape>
Outer circle outer.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<stroke android:color="#color/colorGreen"
android:width="2dp"/>
</shape>
Button background background.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/outer"
android:right="0dp"
android:top="0dp"
android:bottom="0dp"
android:left="0dp"
android:gravity="center"/>
<item android:drawable="#drawable/inner"
android:right="4dp"
android:top="4dp"
android:bottom="4dp"
android:left="4dp"
android:gravity="center"/>
</layer-list>
And this is final result

Android shape border with gradient and middle transparent

I need to create a round corner border, where border with gradient.enter link description here is working.But My page is using a image as background which is also with gradient. I need to show background image from middle of the filed. I want to create just like below image:
round_background.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="4dp"
android:color="#color/transparent" />
<gradient
android:startColor="#374533"
android:centerColor="#432727"
android:endColor="#222430"
android:angle="135"/>
<corners android:radius="10dp" />
</shape>
round_border.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:startColor="#efe301"
android:centerColor="#7dc17b"
android:endColor="#01dae6"
android:angle="180"/>
<corners android:radius="10dp" />
result_drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/round_border"/>
<item android:drawable="#drawable/round_background" />
</layer-list>
Here, you can set android:width="4dp" in round_background.xml to set size of your border. use result result_drawable.xml where you want..
Enjoy. :}

Unable to understand layer-list

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:top="4dp"
android:right="4dp"
android:bottom="4dp"

</shape>
</item>
<item>
<shape
android:shape="oval">

How is it giving me a ring shape?
How layer-list works and What do top, right, bottom and left attributes of item tag do?
Cant we just use ring shape ?Why go for oval shape to make ring shape?
A layer list is drawable, called sequence of other drawables with <item> tag.
Here from your question the first <item> is inner oval shape & top, bottom, right & left are insets given to that item (just same as padding). Try to give width & height to first you can see inner oval shape with 4dp padding from outer oval.
Refer to this link for more detail about layer drawable http://developer.android.com/reference/android/graphics/drawable/LayerDrawable.html
Yes you can use ring shape to draw a ring like:
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="ring"
android:innerRadius="15dp"
android:thickness="10dp"
android:useLevel="false">
<solid android:color="#ff0000" />
</shape>
