Android shape border with gradient

Question

I want to create a border for a linearLayout. So I decide to create a shape. I want the border to have a gradient. The following is not doing it. It fills the rectangle and then creates a stroke. I don't want a filled rectangle, just the stroke. And I want to apply the gradient to the stroke.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <gradient
        android:angle="360"
        android:centerColor="#e95a22"
        android:endColor="#ff00b5"
        android:gradientRadius="360"
        android:startColor="#006386"
        android:type="sweep" />

    <stroke
        android:width="2dp"
        android:color="#ff207d94" />

</shape>

Solution 1

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="rectangle" >
            <gradient
                android:angle="360"
                android:centerColor="#e95a22"
                android:endColor="#ff00b5"
                android:gradientRadius="360"
                android:startColor="#006386"
                android:type="sweep" />

            <stroke
                android:width="2dp"
                android:color="#ff207d94" />
        </shape>
    </item>
    <item
        android:bottom="2dp"
        android:left="2dp"
        android:right="2dp"
        android:top="2dp">
        <shape android:shape="rectangle" >
            <solid android:color="#fff" />
        </shape>
    </item>

</layer-list>

Solution 2

since the accepted answer didn't work exactly as i wanted it to work for me, i'll post my solution too, maybe it helps someone else :)

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<item>
<!-- create gradient you want to use with the angle you want to use -->
    <shape android:shape="rectangle" >
        <gradient
            android:angle="0"
            android:centerColor="@android:color/holo_blue_bright"
            android:endColor="@android:color/holo_red_light"
            android:startColor="@android:color/holo_green_light" />

    </shape>
</item>
<!-- create the stroke for top, left, bottom and right with the dp you want -->
<item
    android:bottom="2dp"
    android:left="2dp"
    android:right="2dp"
    android:top="2dp">
    <shape android:shape="rectangle" >
        <!-- fill the inside in the color you want (could also be a gradient again if you want to, just change solid to gradient and enter angle, start, maybe center, and end color) -->
        <solid android:color="#fff" />
    </shape>
</item>

</layer-list>

Solution 3

This will create a layout with top border of 2dp. just set it as a background to your layout

<?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="#4fc949"
                android:centerColor="#0c87c5"
                android:endColor="#b4ec51"
                android:angle="180" />
        </shape>
    </item>
    <item android:top="2dp">
        <shape android:shape="rectangle">
            <solid android:color="@color/background_color"/>
        </shape>
    </item>
</layer-list>

Solution 4

This would be the appropriate solution to what you wanna do. It includes gradient in stroke as well as a gradient in fill colour.

<?xml version="1.0" encoding="utf-8"?>
    <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
        <item>
            <shape >
                <gradient
                    android:startColor="#2196F3"
                    android:endColor="#673AB7"
                    android:angle="270" />
                <stroke
                    android:width="0dp"
                    android:color="@color/transparentColor" />
                <corners
                    android:radius="8dp" />
                <padding
                    android:left="2dp"
                    android:right="2dp"
                    android:top="2dp"
                    android:bottom="2dp" />
            </shape>
        </item>
        <item>
            <shape android:shape="rectangle">

            </shape>
        </item>
        <item android:top="0dp">
            <shape>
                <gradient
                    android:startColor="#FBB100"
                    android:endColor="#FF9900"
                    android:angle="270"/>

                <corners
                    android:radius="8dp" />
            </shape>
        </item>
    </layer-list>

This extra source should fix your problem

<?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:angle="360"
                android:centerColor="#e95a22"
                android:endColor="#ff00b5"
                android:gradientRadius="360"
                android:startColor="#006386"
                android:type="sweep" />
            <size android:height="170dp"
                android:width="170dp"/>
        </shape>
    </item>
    <item android:top="2dp" android:bottom="2dp" android:right="2dp" android:left="2dp">
        <shape android:shape="rectangle">
            <size android:width="140dp"
                android:height="140dp"/>
            <solid android:color="@color/colorAccent"/>
            <solid android:color="@color/white"/>
        </shape>
    </item>
</layer-list>

thanx it helped me :)

After a lot of searches, I got the perfect solution. Thank you so much :)

[CoolMind]

Thanks! What for is an empty second <item>? What for is the first <stroke> with transparent color?

[Starwave]

Not perfect, since my EditTexts' fill is supposed to be transparent.

[Distra]

Starwave in the solid rectngle you should be able to use @android:color/transparent this should do the trick. or you just use alpha by setting the collor to e.g. #00FFFFFF

[HAXM]

I want to add radius on the corners, how can I define the corner radius?

[Distra]

@HAXM inside the <shape tag add e.g. <corners android:radius="12dp" /> for a 12 dp corner radius. <shape android:shape="rectangle" > <corners android:radius="12dp" /> </shape> If you need different corner radius for each corner you can use bottomLeftRadius, bottomRightRadius, topLeftRadius and topRightRadius instead of radius.
