Change background colour onClick() - android

I have a ImageView and a tag_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="#272822">
</solid>
<stroke android:color="#686868" android:width="1dp">
</stroke>
<corners android:radius="8dp"/>
</shape>
What changes should i make so to :
change the background colour of the background when the imageview is clicked. i have used this tag_layout as :
<ImageView
android:background="#drawable/tag_layout"
android:padding="5dp"
android:scaleType="fitCenter"
android:layout_marginRight="5dp"
android:layout_width="0dp"
android:layout_height="37dp"
android:src="#drawable/zoomin"
android:layout_weight="1"
/>
How do i assign on click colours in a xml file ?


This should be enough
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<shape android:shape="rectangle">
<solid android:color="#yourcoloronpressed"/>
<stroke android:color="#686868" android:width="1dp"/>
<corners android:radius="8dp"/>
</shape>
</item>
<item>
<shape android:shape="rectangle">
<solid android:color="#272822"/>
<stroke android:color="#686868" android:width="1dp"/>
<corners android:radius="8dp"/>
</shape>
</item>
</selector>
Replace the yourcoloronpressed by your color.
You can also change the other atributes like stroke and corners on pressed, of course.

How to achieve custom shape match parent?

I created custom shape in XML:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item>
<shape android:shape="rectangle">

<item
android:drawable="#drawable/down_arrow_red"
android:width="10dp"
android:height="6dp"
android:gravity="center|right"/>
</layer-list>
</item>
</selector>
Since match parent wasn't allowed while defining of width and height, I am worried how this shape will look like on different size screens. How to make this shape match parent screen? Thanks!

I think what you want to ask is about sizing.
<?xml version="1.0" encoding="utf-8"?>

<stroke
android:width="1dp"

<corners android:radius="15dp" />
</shape>
</item>
<item
android:width="10dp"

Seekbar thumb with transparent right and left padding/margin

Summarize the problem:
Hello, I want to create Seekbar like this one in the design:
So the thumb has something like padding/margin at left and right and bars are rounded on both sides.
What I've tried so far:
I've already tried to create thumb picture like this:
Unfortunately, it turned out that I can't use this picture because I need to change this black halo around green point programmatically.
That's why I've built seekbar completely in XML (no pngs images):
Seekbar:
<SeekBar
android:id="#+id/player_seekbar"
android:layout_width="0dp"
android:layout_height="wrap_content"
style="#style/SeekBarPlayer"
local:MvxBind="Max Duration; Progress SliderPosition, Mode=OneWay; SecondaryProgress Downloaded; Visibility(LivePlaybackToVisibility(CurrentTrack))"
android:layout_marginTop="16dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/cardView" />
SeekbarBackground:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<corners android:radius="5dp" />
<solid android:color="#3d4b58" />
</shape>
</item>
</layer-list>
SeekbarSecondaryProgress:
<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/progressshapesecondary" >
<clip>
<shape
android:shape="rectangle" >
<size android:height="5dp"/>
<corners
android:radius="5dp" />
<solid android:color="#8883e76b"/>
</shape>
</clip>
</item>
</layer-list>
SeekbarProgress:
<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/progressshape" >
<clip>
<shape
android:shape="rectangle" >
<size android:height="5dp"/>
<corners
android:radius="5dp" />
<solid android:color="#83e76b"/>
</shape>
</clip>
</item>
</layer-list>
And it provides me a seekbar like this:
Summarazing
How can I achieve the following seekbar design from now on?

Use below code for thumb drawable:
seekbar_thumb.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<solid android:color="#8883e76b"/>
<stroke android:color="#color/black" android:width="3dp"/>
<size android:height="30dp" android:width="30dp"/>
</shape>
</item>
</selector>
Use below code for seekbar, just change color what you want:
<item android:id="#android:id/background">
<shape android:shape="rectangle">
<corners android:radius="20dp" />
<solid android:color="#color/fofo_grey" />
</shape>
</item>
<item android:id="#android:id/progress">
<clip>
<shape android:shape="rectangle">
<corners android:radius="20dp" />
<solid android:color="#color/signup_green" />
<stroke
android:width="6dp"
android:color="#color/fofo_grey" />
</shape>
</clip>
</item>

How do you create a layer-list with two solids next to each other?

I'm trying to create a drawable with two shapes next to each other using layer-list, how would I do it?

You can use the following code to have the drawable you want(Change the colors and height as you want)
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:gravity="center">
<shape android:shape="rectangle">
<size
android:width="5dp"
android:height="5dp" />
<solid android:color="#color/colorAccent"/>
</shape>
</item>
<item android:gravity="right">
<shape android:shape="rectangle">
<size
android:width="1dp"
android:height="5dp" />
<solid android:color="#color/colorPrimary"/>
</shape>
</item>
</layer-list>

How can I create the following shape in Android?

I am trying to create a following shape in android.
I tried following code but it's only for changing the corners
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#ffffff" />
<gradient
android:startColor="#00EBCF"
android:endColor="#00BEEC"
android:angle="180"
android:type="linear" />
<corners
android:bottomLeftRadius="80dp"
android:bottomRightRadius="80dp"
android:topLeftRadius="0dp"
android:topRightRadius="0dp" />
What do I need to make changes in code to achieve the above shape?
Edit1
As per the answer I used following code (modifications in layout height):
<?xml version="1.0" encoding="utf-8"?>
</shape>
</item>
<item
android:width="1500dp"
android:height="200dp"
android:top="95dp">
<shape android:shape="oval">
<solid android:color="#36D6E9" />
</shape>
</item>
But when I am using this layout as a background for LinearLayout. It's showing me this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#drawable/header_shape_rect">

use this as an example
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:height="200dp">
<shape android:shape="rectangle">
<solid android:color="#ccc"/>
</shape>
</item>
<item android:height="200dp" android:top="95dp" android:width="1500dp" >
<shape android:shape="oval">
<solid android:color="#ccc"/>
</shape>
</item>
</layer-list>

Style bottom Line in Android

I need to create an android shape so that only the bottom has stroke (a dashed line). When I try the following, the stroke bisects the shape right through the center. Does anyone know how to get it right? the stroke needs to be the bottom line/border. I am using the shape as a background to a TextView. Please, never mind why I need it.
<?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="#1bd4f6" />
</shape>
</item>
<item>
<shape android:shape="line" >
<padding android:bottom="1dp" />
<stroke
android:dashGap="10px"
android:dashWidth="10px"
android:width="1dp"
android:color="#ababb2" />
</shape>
</item>
</layer-list>

It's kind of a hack, but I think this is probably the best way to do it. The dashed line will always be on the bottom, regardless of the height.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle" >
<solid android:color="#1bd4f6" />
</shape>
</item>
<item android:top="-2dp" android:right="-2dp" android:left="-2dp">
<shape>
<solid android:color="#android:color/transparent" />
<stroke
android:dashGap="10px"
android:dashWidth="10px"
android:width="1dp"
android:color="#ababb2" />
</shape>
</item>
</layer-list>
Explanation:
The second shape is transparent rectangle with a dashed outline. The key in making the border only appear along the bottom lies in the negative margins set the other sides. These negative margins "push" the dashed line outside the drawn area on those sides, leaving only the line along the bottom. One potential side-effect (which I haven't tried) is that, for views that draw outside their own bounds, the negative-margin borders may become visible.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:top="-6dp"
android:left="-6dp"
android:right="-6dp"
android:bottom="0dp">
<shape android:shape="rectangle">
<solid android:color="#88FFFF00"/>
<stroke
android:width="5dp"
android:color="#FF000000"/>
</shape>
</item>
</layer-list>

This does the trick...
<item >
<shape android:shape="rectangle">
<solid android:color="#YOUR_BOTTOM_LINE_COLOR"/>
</shape>
</item>
<item android:bottom="1.5dp">
<shape android:shape="rectangle">
<solid android:color="#YOUR_BG_COLOR"/>
</shape>
</item>

I feel it is straightforward, without all this negative paddings or storks.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/main_bg_color"/>
<item android:gravity="bottom">
<shape android:shape="rectangle">
<size android:height="5dp"/>
<solid android:color="#color/bottom_bar_color"/>
</shape>
</item>
</layer-list>

This answer is for those google searchers who want to show dotted bottom border of EditText like here
Create dotted.xml inside drawable folder and paste these
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="1dp"
android:left="-2dp"
android:right="-2dp"
android:top="-2dp">
<shape android:shape="rectangle">
<stroke
android:width="0.5dp"
android:color="#android:color/black" />
<solid android:color="#ffffff" />
<stroke
android:width="1dp"
android:color="#030310"
android:dashGap="5dp"
android:dashWidth="5dp" />
<padding
android:bottom="5dp"
android:left="5dp"
android:right="5dp"
android:top="5dp" />
</shape>
</item>
</layer-list>
Then simply set the android:background attribute to dotted.xml we just created. Your EditText looks like this.
<EditText
android:id="#+id/editText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Some Text"
android:background="#drawable/dotted" />

Try next xml drawable code:
<layer-list>
<item android:top="-2dp" android:right="-2dp" android:left="-2dp">
<shape>
<solid android:color="#android:color/transparent" />
<stroke
android:width="1dp"
android:color="#fff" />
</shape>
</item>
</layer-list>

I think you do not need to use shape if I understood you.
If you are looking as shown in following image then use following layout.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#1bd4f6"
android:paddingBottom="4dp" >
<TextView
android:layout_width="200dp"
android:layout_height="wrap_content"
android:background="#ababb2"
android:padding="5dp"
android:text="Hello Android" />
</RelativeLayout>
</RelativeLayout>
EDIT
play with these properties you will get result
android:top="dimension"
android:right="dimension"
android:bottom="dimension"
android:left="dimension"
try 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="#1bd4f6" />
</shape>
</item>
<item android:top="20px"
android:left="0px">
<shape android:shape="line" >
<padding android:bottom="1dp" />
<stroke
android:dashGap="10px"
android:dashWidth="10px"
android:width="1dp"
android:color="#ababb2" />
</shape>
</item>
</layer-list>

A Simple solution :
Create a drawable file as edittext_stroke.xml in drawable folder.
Add the below code:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line"
>
<stroke
android:width="1dp"
android:color="#android:color/white" >
</stroke>
</shape>
In layout file , add the drawable to edittext as
android:drawableBottom="#drawable/edittext_stroke"
<EditText
android:textColor="#android:color/white"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawableBottom="#drawable/edittext_stroke"
/>

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)

use this xml change the color with your choice.
<item>
<layer-list>
<item>
<shape>
<solid android:color="#color/gray_500" />
</shape>
</item>
<!-- CONTENT LAYER -->
<item android:bottom="2dp" >
<shape>
<solid android:color="#ffffff" />
</shape>
</item>
</layer-list>
</item>
In Case if you want programmatically
public static Drawable getStorkLineDrawable(#ColorInt int colorStrok, int iSize, int left, int top, int right, int bottom)
{
GradientDrawable gradientDrawable = new GradientDrawable();
gradientDrawable.setShape(GradientDrawable.RECTANGLE);
gradientDrawable.setStroke(iSize, colorStrok);
LayerDrawable layerDrawable = new LayerDrawable(new Drawable[]{gradientDrawable});
layerDrawable.setLayerInset(0, left, top, right, bottom);
return layerDrawable;
}
call this method like
Drawable yourLineDrawable= getStorkLineDrawable(yourColor, iSize, -iSize, -iSize, -iSize, 0);

easiest way to do this is put after that view where you want bottom border
<?xml version="1.0" encoding="utf-8"?>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#color/colorPrimary" />

This worked best for me:
<?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" android:bottom="0dp">
<shape android:shape="rectangle">
<stroke android:width="4dp" android:color="#ff0000"/>
</shape>
</item>
</layer-list>
Shows the line on the bottom only. You can easily change with stroke width to size you like and also update the top, left, right on the accordingly.

Simply add -
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!--Minus (-) how much dp you gave in the stroke width from left right top-->
<item android:left="-10dp" android:right="-10dp" android:top="-10dp">
<shape
android:shape="rectangle">
<stroke
android:dashGap="10dp"
android:dashWidth="10dp"
android:width="10dp"
android:color="#android:color/holo_red_dark" />
<!--This is the main background -->
<solid android:color="#FFDDDDDD" />
</shape>
</item>
</layer-list>
Preview -

it is completely transparent Edittext with transparent background.
<item>
<shape android:shape="rectangle" >
<solid android:color="#color/transparent" />
</shape>
</item>
<item android:top="-3dp" android:right="-3dp" android:left="-3dp">
<shape>
<solid android:color="#android:color/transparent" />
<stroke
android:width="2dp"
android:color="#color/bottomline" />
</shape>
</item>

A Simple solution :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="-1dp"
android:left="-1dp"
android:right="-1dp"
android:top="-1dp">
<shape android:shape="rectangle">
<solid android:color="#AARRGGBB" />
<stroke
android:width="5dp"
android:color="#android:color/red"
android:dashWidth="10dp"
android:dashGap="12dp" />
</shape>
</item>
</layer-list>
And finally we have something like that :)

This is rectangular background with bottom stroke
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<corners android:radius="4dp" />
<solid android:color="#f2f4f5" />
<stroke
android:width="3dp"
android:color="#002f34" />
<padding android:bottom="4dp" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<corners android:radius="4dp" />
<solid android:color="#f2f4f5" />
</shape>
</item>
</layer-list>
