Custom drawable not showing properly when applied to a layout

Custom drawable not showing properly when applied to a layout - android

I designed a custom shape
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="0dp"
android:left="30dp"
android:right="30dp"
android:top="-30dp">
<shape android:shape="rectangle">
<size
android:width="80dp"
android:height="40dp" />
<solid android:color="#color/colorPrimary" />
<corners
android:bottomLeftRadius="0dp"
android:bottomRightRadius="0dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<size
android:width="100dp"
android:height="40dp" />
<solid android:color="#color/colorPrimary" />
<corners android:radius="0dp" />
</shape>
</item>
</layer-list>
Now when I try to apply this to a layout background Which is BottomSheet it doesn't have any effect and simply covers up the entire screen with blue background (It becomes a solid flat blue rectangle)
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/bottom_sheet"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/background_features"
android:padding="32dp"
app:behavior_hideable="false"
app:behavior_peekHeight="#dimen/partial_features_peek_height_50dp"
app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">
How can I apply this custom background in its shape

You can try it
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="0dp"
android:left="30dp"
android:right="30dp">
<shape android:shape="rectangle">
<size
android:width="80dp"
android:height="40dp"/>
<solid android:color="#color/colorPrimary"/>
<corners
android:bottomLeftRadius="0dp"
android:bottomRightRadius="0dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp"/>
</shape>
</item>
<item
android:top="30dp"
>
<shape android:shape="rectangle">
<size
android:width="100dp"
android:height="40dp"/>
<solid android:color="#color/colorPrimary"/>
<corners android:radius="0dp"/>
</shape>
</item>
</layer-list>
Let me know the result if it is the layout which you want to achieve or not. Hope it help

use layer list
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Apply the margin value on the "item" element -->
<!-- This example creates a 15dp visible margin around the dialog -->
<item
android:top="15dp"
android:bottom="15dp"
android:left="15dp"
android:right="15dp">
<shape
android:shape="rectangle">
<!-- Add attributes specific to your background (e.g. corner radius, colors, etc.) -->
<!-- Set "padding" at minimum to match margin and add additional content padding as well, if desired -->
<!-- This example creates 10dp of internal padding for content -->
<padding
android:top="25dp"
android:bottom="25dp"
android:left="25dp"
android:right="25dp" />
</shape>
</item>
</layer-list>

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"?>

</shape>

How to add inner shadow effect in drawable android?

I want to add inner shadow effect into my drawable file like this.
Below is my drawable file. I want to achieve shadow inside the drawable file as you can see above. What changes should i make to achieve this?
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"

</item>
<!-- left shadow -->

<shape android:shape="rectangle">
<gradient
android:angle="180"

<corners android:radius="8dp" />
</shape>
</item>
<!-- right shadow -->
<item>
<shape android:shape="rectangle">
<gradient

</shape>
</item>
</layer-list>
The image would look like image

You can make many item inside your layer-list to produce shadow effect inside check this one out Add shadow to custom shape on Android.
You just need to change some values to achieve your wanted output. make the radius to get oval form and the values of colors.

Rectangle in xml without bottom side

I have a shape rectangle in my drawable like this
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="2dp"
android:topRightRadius="0dp"
android:bottomRightRadius="0dp"
android:bottomLeftRadius="0dp"/>
<stroke
android:width="1dp"
android:color="#android:color/white"
/>
</shape>
How, can I hide bottom line ?

<?xml version="1.0" encoding="UTF-8"?>
<!-- inset is used to remove border from top, it can remove border from any other side-->
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:insetTop="-2dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:id="#+id/rectangle">
<stroke android:width="1dp" android:color="#b7b7b7" />
<corners android:bottomRightRadius="5dp" android:bottomLeftRadius="5dp"/>
<solid android:color="#454444"/>
</shape>
</inset>

use this code
<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android">
<!-- the line -->
<item>
<shape>
<solid android:color="#yourColor"
/>
</shape>
</item>
<!-- This is full view -->
<item android:bottom="10dp">
<shape>
<solid android:color="#backGroundColor" />
</shape>
</item>
this will add a 10dp height line at bottom of your view , u can change size of the line with
<item android:bottom="10dp">
and change color too
good luck

How can I add depth to a shape

I need to make my EditText look like its got depth like in the image below.
I have this shape I don't know what to add to it
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<corners android:radius="50dp" />
<solid android:color="#color/primary_dark" />
</shape>

you can accomplish that with a drawable like this:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!--background to compensate the transparency under shadow and glow (for bigger depth values)-->
<item>
<shape android:shape="rectangle">
<corners android:radius="50dp" />
<solid android:color="#color/primary_dark" />
</shape>
</item>
<!--top, dark, inner shadow-->
<item
android:bottom="#dimen/depth">
<shape android:shape="rectangle">
<corners android:radius="50dp" />
<solid android:color="#1A000000" />
</shape>
</item>
<!--bottom, light, outer glow-->
<item
android:top="#dimen/depth">
<shape android:shape="rectangle">
<corners android:radius="50dp" />
<solid android:color="#4DFFFFFF" />
</shape>
</item>
<!--your color-->
<item
android:top="#dimen/depth"
android:bottom="#dimen/depth">
<shape android:shape="rectangle">
<corners android:radius="50dp" />
<solid android:color="#color/primary_dark />
</shape>
</item>
</layer-list>
and define a dimen in dimens.xml
<dimen name="depth">2dp</dimen>
by changing of the dimen you can change the depth of the drawable

This might also make your field look close to the effect but with a little more depth (see below). It might be worth adding the background to a outer view to wrap the edit text too so you can indent the text if you haven't already done this.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- outer shine -->
<item
android:top="4dp"
android:left="4dp">
<shape android:shape="rectangle">
<corners android:radius="50dp" />
<solid android:color="#1597FB" />
</shape>
</item>
<!-- inner shadow -->
<item>
<shape android:shape="rectangle">
<corners android:radius="50dp" />
<solid android:color="#004173" />
</shape>
</item>
<!-- inner background -->
<item
android:top="2dp"
android:left="2dp">
<shape android:shape="rectangle">
<corners android:radius="50dp" />
<solid android:color="#006EC3" />
</shape>
</item>
</layer-list>
And then you EditText as below;
<FrameLayout
android:layout_width="match_parent"
android:layout_height="60dp"
android:paddingLeft="20dp"
android:paddingRight="20dp"
android:background="#drawable/rounded_rect_layered_combined">
<EditText
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent"
android:textColor="#ffffff"/>
</FrameLayout>

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>
