I am trying to create a simple layer-list drawable for my Android app. When I set the drawable as src of an ImageView it is not drawn correctly:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:top="20dp">
<shape android:shape="oval">
<solid android:color="#color/dark_gray" />
</shape>
</item>
<item android:left="20dp">
<shape android:shape="oval">
<solid android:color="#color/dark_gray" />
</shape>
</item>
</layer-list>
Just two ovals with a little offset to each other. Nothing special (just a test) but it does not work.
It seems that android:left|right|bottom|top is the problem. If I use only of of these commands the drawable is drawn correctly. If two or more are used the ImageView stays empty.
Works:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:top="20dp">
<shape android:shape="oval">
<solid android:color="#color/dark_gray" />
</shape>
</item>
<item>
<shape android:shape="oval">
<solid android:color="#color/dark_gray" />
</shape>
</item>
</layer-list>
Does NOT work (like the first example):
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="..." >
<item android:top="20dp" android:left="20dp">
<shape android:shape="oval">
<solid android:color="#color/dark_gray" />
</shape>
</item>
</layer-list>
What is wrong here?
EDIT: # Rod_Algonquin
I use a quite simple layout to test the drawable:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center"
android:background="#aaa" >
<ImageView
android:id="#+id/image_logo"
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#drawable/testDrawable" >
</ImageView>
</LinearLayout>
It seems that the number of android:left|right|bottom|top arguments is not the source of the problem but the concrete value being used.
This drawable works fine and:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:top="2dp">
<shape android:shape="oval">
<solid android:color="#0f0" />
</shape>
</item>
</layer-list>
This one does not draw anything (the ImageView is just transparent):
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:top="1dp">
<shape android:shape="oval">
<solid android:color="#0f0" />
</shape>
</item>
</layer-list>
The only difference here is the value of android:top. 1dp does not work. 2dp works without any problem.
Any idea?
The problem is that you are using the layer-list drawable as an image resource of the ImageView. android:src will only accept an image not a drawable thus giving you nothing in there.
solution:
Instead of putting it in the android:src put it in the background where you can freely use the drawable.
<ImageView
android:id="#+id/image_logo"
android:layout_width="100dp"
android:layout_height="100dp"
android:background="#drawable/testDrawable" >
</ImageView>

I have to make a shape like this-
For doing this, I have written code like this-
triangle.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<rotate
android:fromDegrees="45"
android:pivotX="-45%"
android:pivotY="97%"
android:toDegrees="45" >
<shape android:shape="rectangle" >
<solid android:color="#color/nypd_blue" />
</shape>
</rotate>
</item>
</layer-list>
and rectangle like this-
<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:id="#+id/listview_background_shape">
<stroke android:width="2dp" android:color="#color/nypd_blue" />
<padding android:left="2dp"
android:top="2dp"
android:right="2dp"
android:bottom="2dp" />
<solid android:color="#color/nypd_blue" />
</shape>
</item>
</layer-list>
Together I am placing them in a xml file like this-
background.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/blue_triangle" android:id="#+id/triangle" android:gravity="top"
android:top="0dp" android:bottom="0dp" android:left="0dp" android:right="0dp"
/>
<item android:drawable="#drawable/blue_rectangle" android:gravity="bottom"
android:height="10dp"
/>
</layer-list>
When I am using background .xml in my code for setting the background,the whole image is not getting displayed properly and only the rectangle part is coming. What is the problem here?
<LinearLayout android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<RelativeLayout android:id="#+id/hours_spent_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/width_1dp"
android:background="#drawable/background">
It seems you test your code on device whose API is below 26.In fact, I don't know how to explain why LayerDrawable behaves differently below API 26. But I have a solution.
RelativeLayout relativeLayout;// your layout
LayerDrawable drawable = (LayerDrawable) relativeLayout.getBackground();
drawable.setLayerInset(1, padding, padding, padding, padding);
"1" means index 1, in your code "1" means #drawable/blue_rectangle and you can set padding manually.
Note you should convert dp to pixel.
how can I create rectangle shape by using two different colors with shadow? like above image.
Please create a drawable file and put the below code in it.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<size android:height="20dp" />
<solid android:color="#F66D08" />
</shape>
</item>
<item android:top="50dp">
<shape android:shape="rectangle" >
<gradient android:endColor="#AD1B1D"
android:startColor="#E2360A"
android:angle="270" />
</shape>
</item>
</layer-list>
layer-list can be used to solve this
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<size
android:width="40dp"
android:height="40dp" />
<solid android:color="#F86F05" />
</shape>
</item>
<item android:top="10dp">
<shape android:shape="rectangle">
<size
android:width="30dp"
android:height="30dp" />
<solid android:color="#B31F19" />
</shape>
</item>
</layer-list>
And the screenshot of the same.
If you want gradient instead of solid color, change solid to gradient and set startColor, endColor and angle.
Place these code in your activity_main :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:gravity="center"
android:background="#F66D08"
android:layout_width="match_parent"
android:layout_height="20dp">
</LinearLayout>
<LinearLayout
android:background="#drawable/introslidergradiant"
android:layout_width="match_parent"
android:layout_height="100dp"></LinearLayout>
</LinearLayout>
And create drawble res file with introslidergradiant.xml name :
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient
android:angle="90"
android:startColor="#A31720"
android:endColor="#E1350B"
android:type="linear" />
</shape>
</item>
</selector>
You have to make a xml file in the drawable
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<gradient
android:type="linear"
android:startColor="#FFFF820D"
android:endColor="#FFA32815"
android:angle="90"/>
</shape>
use the following code or you can generate your own gradient here just set the color and select the android option and it will generate the gradient for you .
I need to make the below shape using xml.
I have created an oval shape using below xml code.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- This is the line -->
<item android:height="400dp"><shape
android:shape="oval">
<solid android:color="#000000" />
</shape></item>
</layer-list>
But I am not able to draw a line and circle together. Please help me to make the above shape using xml.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#color/comment_background"/>
<stroke android:color="#color/gray" android:width="0.5dp"/>
</shape>
This is Code for Creating Circle shape in android
Finally I have come with a solution after little googling.
Followed steps:-
1.Created a xml file called dot.xml in drawable folder to draw a dot or filled circle.
//Dot.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval" >
<solid android:color="#color/colorTimeline" />
</shape>
2.Inserted below code into layout file.
<View
android:id="#+id/v1"
android:layout_width="1dp"
android:layout_height="50dp"
android:background="#color/colorTimeline"
android:contentDescription="ad"
android:layout_marginStart="10dp"/>
<View
android:id="#+id/v2"
android:layout_width="16dp"
android:layout_height="16dp"
android:background="#drawable/dot"
android:contentDescription="f"
android:layout_marginStart="3dp"
android:layout_below="#id/v1"
android:layout_marginEnd="24dp"/>
<View
android:id="#+id/v3"
android:layout_width="1dp"
android:layout_height="50dp"
android:background="#color/colorTimeline"
android:contentDescription="ad"
android:layout_marginStart="10dp"
android:layout_below="#id/v2"/>
Final Output :-
Output Screenshot
My eyes bleeding, when i see your solution, sorry. I had to create and show you this one. Remember this example works only for known size of view. If you want to use dynamic values create my example drawable programatically.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- VERTICAL LINE -->
<item
android:left="9dp"
android:right="9dp">
<shape
android:shape="rectangle">
<solid
android:color="#FF0000" />
<size
android:width="2dp"
android:height="200dp" />
</shape>
</item>
<!-- OVAL -->
<item
android:top="90dp"
android:bottom="90dp">
<shape
android:shape="oval">
<solid
android:color="#FF0000" />
<size
android:width="20dp"
android:height="20dp" />
</shape>
</item>
</layer-list>
If you need any explanation just let me know.
I need to set size for item in layer-list. For using as windowBackground in launch activity. I wrote this XML file and Android Studio displays it correctly. But in application the logo always full screen. How to make it?
<?xml version="1.0" encoding="utf-8"?>
<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" >
<gradient
android:endColor="#000004"
android:gradientRadius="1000"
android:startColor="#1f3371"
android:type="radial" >
</gradient>
</shape>
</item>
<item>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/texture_5"
android:tileMode="repeat" />
</item>
<item android:drawable="#drawable/logo"
android:height="100dp"
android:width="77dp"
android:gravity="center"
>
</item>
</layer-list>
I found solution, but I expected better way.
Here is final code:
<?xml version="1.0" encoding="utf-8"?>
<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" >
<gradient
android:endColor="#000004"
android:gradientRadius="1000"
android:startColor="#1f3371"
android:type="radial" >
</gradient>
</shape>
</item>
<item>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/texture_5"
android:tileMode="repeat" />
</item>
<item android:drawable="#drawable/logo"
android:bottom="214dp"
android:top="214dp"
android:left="100dp"
android:right="100dp"
android:gravity="center"
android:tileMode="repeat"
>
</item>
</layer-list>
At least it works at xxhdpi and xhdpi without distortion.
Starting from API 23, it is possible to set width and height right within the "item" tag:
<item android:drawable="#drawable/logo" android:width="..." android:height="..." />
You can do the followin
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/blanco"/>
<item
android:width="200dp"
android:height="200dp"
android:gravity="center">
<bitmap
android:gravity="fill"
android:src="#drawable/your_image"
android:mipMap="true"/>
</item>
</layer-list>
Just change width and height
I had the same problem and found the solution here.
I had to use my vector drawable as the source to a bitmap object:
<item>
<bitmap
android:gravity="center"
android:src="#drawable/ic_logo_splash"/>
</item>
I want to create a custom View based on ImageView to make a widget as below where the drawable source is the camera and the background is the rectangle with the tick sign:
The problems are:
I can not create the border with the tick sign on the right: the tick is stretched fullscreen instead of staying at the bottom right.
The tick sign is sometime behind the image if I set it with android:background.
Here are my xml files:
The current border xml drawable
<?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"/>
<stroke
android:width="2dip"
android:color="#color/bg_black"/>
<padding
android:left="3dp"
android:right="3dp"
android:top="3dp"
android:bottom="3dp"
/>
</shape>
</item>
<item >
<layer-list >
<item>
<shape
android:shape="rectangle">
<stroke
android:width="2dp"
android:color="#color/border_yellow"/>
<size
android:width="37dp"
android:height="37dp"/>
<padding
android:bottom="3dp"
android:left="3dp"
android:right="3dp"
android:top="3dp"/>
</shape>
</item>
<item android:drawable="#drawable/ic_tick"/>
</layer-list>
</item>
</layer-list>
The Image Button xml layout
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/product1"
android:background="#drawable/toggle_rectangle_check"/>
Thanks for your time.
I'm not sure if this is the sort of solution you'd be looking for but instead of having an xml file with the styling in it, I believe it would be better to have a layout file which defines your layout for your custom Widget, Something like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/customWidgetBox"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/customCheckmark"
android:gravity="bottom|right" />
</LinearLayout>
And to the drawable folder you would need to add both the customCheckmark.xml and customWidgetBox.xml
customCheckmark.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<item android:drawable="#drawable/check_mark">
<stroke android:width="3dp" android:color="#color/blue_button_border" />
</item>
</shape>
customWidgetBox.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<item android:drawable="#drawable/camera">
<stroke android:width="3dp" android:color="#color/blue_button_border" />
</item>
</shape>
Not sure if this code accomplish exactly what you want, but it'll be a good help to get you started because this is definitely the way to do it! :)
