I wish to use a button of this shape,pointing to right or left in my app.
Two corners of the button are rounded, and the other side is triangular.
I was able to accomplish this somewhat using a png image as background, but I would prefer to know how to do it in xml.
Not sure about the exact way to do that, but you could always increase the radius of the topLeft and bottomLeft or Right to maximum, to get a semicircular pointing end.
This is how I tried to do it
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<corners
android:topLeftRadius="100dp"
android:topRightRadius="31dp"
android:bottomLeftRadius="100dp"
android:bottomRightRadius="31dp"
/>
<gradient
android:angle="45"
android:centerX="35%"
android:centerColor="#7995A8"
android:startColor="#E8E8E8"
android:endColor="#000000"
android:type="linear"
/>
<size
android:width="172dp"
android:height="60dp"
/>
<stroke
android:width="3dp"
android:color="#878787"
/>
</shape>
This is how it looks..
The usual practice is to use images for complex shapes. In case you a trying to control the app size, you could use one image that points in one direction and rotate it in drawable xml to point the other way.
However, if you really want implement this in xml, I have got a triangle pointing left/ right below. You can try improving on this to suit your requirement.
Right Pointing,
<?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="0%"
android:pivotY="0%"
android:toDegrees="0">
<shape android:shape="rectangle">
<solid android:color="#color/colorAccent" />
</shape>
</rotate>
</item>
</layer-list>
Left Pointing,
<?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="100%"
android:pivotY="0%"
android:toDegrees="0">
<shape android:shape="rectangle">
<solid android:color="#color/colorAccent" />
</shape>
</rotate>
</item>
</layer-list>
You can make a shape like that using layer list, read more about layer list here. This should give you the desired output :
<?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="100dp"
android:height="40dp" />
<solid android:color="#5e88b8" />
<corners android:topRightRadius="3dp" android:bottomRightRadius="3dp" android:radius="0dp"/>
</shape>
</item>
<item
android:top="-40dp"
android:bottom="65dp"
android:left="-30dp">
<rotate
android:fromDegrees="-45">
<shape android:shape="rectangle">
<solid android:color="#ffffff" />
</shape>
</rotate>
</item>
<item
android:top="65dp"
android:bottom="-40dp"
android:left="-30dp">
<rotate
android:fromDegrees="45">
<shape android:shape="rectangle">
<solid android:color="#ffffff" />
</shape>
</rotate>
</item>
</layer-list>
and then set it as the button background :
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/button_background"
android:text="button" />
OUTPUT :
UPDATE
Change the corner radius to get the desired corner look.
You can use a MaterialButton with the shapeAppearanceOverlay attribute:
<com.google.android.material.button.MaterialButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="BUTTON"
app:shapeAppearanceOverlay="#style/ShapeAppearanceOverlay.App.CutAndRound"
/>
with:
<style name="ShapeAppearanceOverlay.App.CutAndRound" parent="">
<item name="cornerFamilyBottomLeft">cut</item>
<item name="cornerFamilyTopLeft">cut</item>
<item name="cornerSizeBottomLeft">50%</item>
<item name="cornerSizeTopLeft">50%</item>
</style>
i want to make a toolbar like shown in the image. i have search a lot but could not find any clue how to make toolbar having different height at right and left.
i would be thankful if someone give any idea or refer any blog.
I want a toolbar at an angle as shown in image below.
You can use layerlist to give left heigh and right height to buttons
this is a working example
Here is the shape file called arrow_shape.xml:
<?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="100dp"
android:height="40dp" />
<solid android:color="#5EB888" />
<corners android:radius="0dp"/>
</shape>
</item>
<item
android:top="-40dp"
android:bottom="65dp"
android:right="-30dp">
<rotate
android:fromDegrees="45">
<shape android:shape="rectangle">
<solid android:color="#ffffff" />
</shape>
</rotate>
</item>
<item
android:top="65dp"
android:bottom="-40dp"
android:right="-30dp">
<rotate
android:fromDegrees="-45">
<shape android:shape="rectangle">
<solid android:color="#ffffff" />
</shape>
</rotate>
</item>
</layer-list>
Then use it as button's background, for example
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/arrow_shape"/>
Here is the screenshot:
More info on Layer-List you can find here.
How can one create such a drawable that will be matching height of given layout ? I know I have to create a some sort of multiple shapes within one drawable but I am kinda lost in this.
Try layer-list of 2 oval shapes and a line. Then set as the background of your view. I'm not sure if it works.
You can also use 9 patch: read this
It should work with xml:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" android:paddingTop="4dp">
<item>
<rotate android:fromDegrees="90" android:gravity="center_horizontal" android:toDegrees="90">
<shape android:shape="line">
<stroke android:color="#000000" android:width="1dp"/>
</shape>
</rotate>
</item>
<item android:gravity="center_horizontal|top" android:height="8dp" android:width="8dp">
<shape android:shape="oval">
<solid android:color="#000000"/>
</shape>
</item>
<item android:gravity="center_horizontal|bottom" android:height="4dp" android:width="4dp">
<shape android:shape="oval">
<solid android:color="#000000"/>
</shape>
</item>
</layer-list>
Is it possible to define a shape like shown on the following image:
I tried a layer-list but I could not find a solution close to what I am looking for.
I want to use the resulting shape as a background image to a RelativeLayout with a transparency.
Any hints are appreciated! Thank you.
Here is the shape you asked for:
<?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="250dp"
android:height="100dp" />
<solid android:color="#ffffff" />
</shape>
</item>
<item
android:top="0dp">
<shape android:shape="line">
<stroke
android:width="25dp"
android:color="#000000" />
</shape>
</item>
<item
android:right="0dp"
android:left="150dp">
<shape android:shape="oval">
<solid android:color="#000000" />
</shape>
</item>
</layer-list>
Screenshot:
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>
