layer-list shapes off screen

layer-list shapes off screen - android

I am trying to create a drawable, where I have 3 circles (on top of each other) on a linear gradient and the circles are shifted 50% to the left.
This is my attempt so far:
<?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="#4833A6"
android:endColor="#1E479C"
android:type="linear"
/>
</shape>
</item>
<item android:left="-115dp">
<shape android:shape="oval">
<size android:width="230dp" android:height="233dp"/>
<solid android:color="#1AFFFFFF"/>
</shape>
</item>
<item android:left="-83dp">
<shape android:shape="oval">
<size android:width="166dp" android:height="166dp"/>
<solid android:color="#1AFFFFFF"/>
</shape>
</item>
<item android:left="-57.5dp">
<shape android:shape="oval">
<size android:width="115dp" android:height="115dp"/>
<solid android:color="#1AFFFFFF"/>
</shape>
</item>
</layer-list>
The desired effect:
What I have so far :(
What am I doing wrong?

Try to put in your item, the following:
<item
android:width="115dp"
android:height="115dp"
android:gravity="center|left"
android:left="-57dp">
<shape android:shape="oval">
<solid android:color="#1AFFFFFF"/>
</shape>
</item>
Don't define the size inside the shape, but inside the item itself. I tried here, and it's working properly.

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>

Android Drawable Shape with 3 layer border

Hi I am trying to add a border to a view which has yellow border but it also has a black border on both sides of primary border.
Any ideas

Try this drawable layout for border on top and bottom
<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<stroke
android:width="2dp"
android:color="#ffff00" />
<solid android:color="#000000" />
</shape>
</item>
<item
android:bottom="2dp"
android:top="2dp">
<shape android:shape="rectangle">
<stroke
android:width="2dp"
android:color="#000000" />
</shape>
</item>
</layer-list>
Try this for left and right border
<?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="#ffff00"/>
</shape>
</item>
<item android:left="4dp">
<shape android:shape="rectangle">
<solid android:color="#000000"/>
</shape>
</item>
<item android:right="4dp">
<shape android:shape="rectangle">
<solid android:color="#000000"/>
</shape>

XML shape android

I have an oval shape that I made rounded, and i want to add a smaller oval in the center of this one with another color. When I try to do this, I can see the smallest and they always have the same size
Can i overlay two shapes without masking the other? i did this but I can see the smallest shape :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
>
<shape android:shape="oval">
<size android:width="170dp"
android:height="170dp"/>
<solid android:color="#f00"/>
</shape>
</item>
<item >
<shape android:shape="oval"
>
<size android:width="140dp"
android:height="140dp"/>
<solid android:color="#f000"/>
</shape>
</item>
</layer-list>

Try This.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<size android:width="170dp"
android:height="170dp"/>
<solid android:color="#f00"/>
</shape>
</item>
<item
android:left="15dp"
android:right="15dp"
android:top="15dp"
android:bottom="15dp">
<shape android:shape="oval" >
<size android:width="140dp"
android:height="140dp"/>
<solid android:color="#f000"/>
</shape>
</item>
</layer-list>
It will display as this image

Add
android:left="6dp"
android:right="6dp"
android:top="6dp"
android:bottom="6dp"
To the inner item tag and check

Shape drawable as background, a line at the bottom

I am using a drawable as a background of a TextView just to have a divider line below the text. A achivied it with this drawable-xml:
<?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="#FFDDDDDD" />
<gradient
android:angle="0"
android:startColor="#FFAAAAAA"
android:endColor="#FFEEEEEE"
/>
</shape>
</item>
<item android:bottom="2dp">
<shape
android:shape="rectangle">
<solid android:color="#FF000000" />
</shape>
</item>
</layer-list>
But this method draws a colored rectangle above a black rectangle. I would like to have just the line at the bottom of the shape with no black rectangle because black is not transparent. How could I achieve that?

This is how I got a line at the bottom for mine. Draw a stroke but then shift the item up and to the sides to get the top and sides to not show the stroke:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:top="-8dp" android:left="-8dp" android:right="-8dp">
<shape>
<solid android:color="#2b7996"/>
<stroke android:color="#33b5e5" android:width="6dp"/>
</shape>
</item>
</layer-list>

I think it's better solution:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:gravity="bottom">
<shape>
<size android:height="1dp" />
<solid android:color="#000000" />
</shape>
</item>
</layer-list>

In general, I try to mess as little as possible with backgrounds unless absolutely necessary, since doing so overrides the default background colors that have states for focused, pressed, etc. I suggest just using an additional view (in a vertical LinearLayout) that is as thick as you need it to be. For example:
<View
android:background="#FF000000"
android:layout_height="2dp"
android:layout_width="fill_parent"/>

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)

With this solution where ever you require different line you can. My requirement was underline only. Even you can give different colors to the layout. You can see in below picture, white line
<?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">
<shape>
<solid android:color="#android:color/transparent"/>
<stroke android:color="#color/white" android:width="5dp"/>
</shape>
</item>
<item android:top="-5dp" android:bottom="-5dp" android:right="-5dp">
<shape>
<solid android:color="#android:color/transparent"/>
<stroke android:color="#color/colorPrimaryDark" android:width="5dp"/>
</shape>
</item>
<item android:bottom="-5dp" android:left="-5dp" android:right="-5dp">
<shape>
<solid android:color="#android:color/transparent"/>
<stroke android:color="#color/colorPrimaryDark" android:width="5dp"/>
</shape>
</item>
<item android:top="-5dp" android:left="-5dp" android:bottom="-5dp">
<shape>
<solid android:color="#android:color/transparent"/>
<stroke android:color="#color/colorPrimaryDark" android:width="5dp"/>
</shape>
</item>
<item android:bottom="2dp" android:left="5dp" android:right="5dp" android:top="5dp">
<shape>
<solid android:color="#color/colorPrimary"/>
<corners android:bottomRightRadius="0dp"
android:bottomLeftRadius="0dp"
android:topLeftRadius="0dp"
android:topRightRadius="0dp" />
</shape>
</item>
</layer-list>

This is a slightly lighter variant of the above.
/drawable/rect_highlight.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<stroke android:width="1px" android:color="#color/colorHighlight"/>
</shape>
/drawable/underline.xml
<inset xmlns:android="http://schemas.android.com/apk/res/android" android:insetLeft="-1px" android:insetRight="-1px" android:insetTop="-1px" android:drawable="#drawable/rect_highlight"/>
Usage:
<TextView ... android:background="#drawable/underline"/>
It's not mine, somebody smarter than I came up with it. If I was smarter, I would have asked who. :)

This solution worked for most of the cases that I needed something like that.
<?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" /> <!--background color of box-->
</shape>
</item>
<item
android:height="2dp"
android:gravity="bottom">
<shape>
<solid android:color="#000000" />
</shape>
</item>
</layer-list>

A simple solution is extending a TextView, then override the onDraw.
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
Paint paint = new Paint();
paint.setColor(ContextCompat.getColor(getContext(),R.color.colorTextUnderLine));
paint.setStrokeWidth(10);
canvas.drawLine(0.0f,canvas.getHeight(),canvas.getWidth(),canvas.getHeight(),
paint);
}
