Half circle shape not work

I try to create half circle background, in development IDE preview it works, but when I launch in emulator it doesn't work.
Here is my shape code :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:height="50dp">
<shape>
<solid android:color="#color/colorAccentDark" />
</shape>
</item>
<item android:top="-500dp" android:bottom="0dp" android:left="-100dp" android:right="-100dp">
<shape>
<corners android:radius="500dp" />
<solid android:color="#color/colorAccentDark" />
</shape>
</item>
</layer-list>
And here is my layout code :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/background_profile"
android:layout_weight="1">
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/profile_avatar"
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#drawable/ic_default_avatar"
android:layout_centerHorizontal="true"
android:layout_marginTop="50dp"/>
<TextView
android:id="#+id/profile_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_below="#id/profile_avatar"
android:layout_marginTop="20dp"
android:textColor="#color/neutralWhite"
android:textStyle="bold"
android:textSize="18sp"
android:text="Avatar Ang"/>
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="4.04">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello Android!"/>
</RelativeLayout>
</LinearLayout>
Maybe any other tweak to handle that?
Thank you

you can try this :
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#900021df"/>
<size
android:width="10dp"
android:height="5dp"/>
<corners
android:bottomLeftRadius="20dp"
android:bottomRightRadius="20dp"/>
</shape>
it gives this shape:

curve_toolbar_bg.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle"/>
</item>
<item
android:bottom="0dp"
android:left="-100dp"
android:right="-100dp"
android:top="-80dp">
<shape android:shape="oval">
<solid android:color="#color/colorPrimary" />
</shape>
</item>
</layer-list>
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar

android:layout_width="0dp"

app:layout_constraintVertical_bias="0.0">
</android.support.v7.widget.Toolbar>
</android.support.constraint.ConstraintLayout>

You cannot create a semicircle from xml. but you could achieve what you are looking for using a circle with appropriate margin & padding.
You can use a circle shape .xml file.
Create a fixed sized circle like this:
Example:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval"
android:useLevel="false" >
<solid android:color="#006AC5" />
<size
android:height="50dp"
android:width="50dp" />
</shape>

Try this. Remove the gradient part then it will look like same as you want.
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#00B0EA" />
</shape>
</item>
<item
android:bottom="400dp"
android:left="-100dp"
android:right="-100dp"
android:top="-200dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<gradient
android:angle="90"
android:endColor="#65FFFFFF"
android:startColor="#65FFFFFF" />
</shape>
</item>
<item
android:bottom="402dp"
android:left="-100dp"
android:right="-100dp"
android:top="-280dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#FFFFFF" />
</shape>
</item>

Background.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#FFFFFF" />
</shape>
</item>
<item
android:bottom="410dp"
android:left="-100dp"
android:right="-100dp"
android:top="-300dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#7181A1" />
</shape>
</item>
</layer-list>
Output like

You can try to use ShapeOfView.
<io.github.florent37.shapeofview.shapes.ArcView
android:layout_width="match_parent"
android:layout_height="300dp"
android:elevation="4dp"
app:shape_arc_height="20dp"

Android seekbar thumb drawable not displayed correctly

I created a custom seekbar thumb, it looks very good on android studio previews, but when running the app on my device, it looks wrong !
what it should look like
what it actually look like on my device
my seekbar_thumb.xml code

</item>
<item android:gravity="center" android:height="15dp" android:width="15dp">
<shape android:shape="oval">

Rounded Corner Bottom TextView inside CardView

I am using CardView to show List Items, where each and every List Item contains two textviews, namely - BOOK NOW/BOOK and DETAIL/DETAILS.
I would like to achieve rounded bottom TextView, but getting in rectangular shape
I have to design something like this:
Here is my XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.CardView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
android:layout_margin="5dp"
app:cardCornerRadius="5dp"
app:cardElevation="2dp">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_weight="1">
.......
<LinearLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="horizontal"
android:layout_marginTop="5dp"
android:background="#color/more"
android:layout_weight="1">
<TextView
android:id="#+id/btnBook"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="BOOK"
android:textColor="#android:color/background_light"
android:padding="5dp"
android:background="#null"
android:textAppearance="?android:textAppearanceMedium"
android:gravity="center" />
<TextView
android:id="#+id/btnDetail"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="DETAILS"
android:background="#null"
android:textColor="#android:color/background_light"
android:padding="10dp"
android:textAppearance="?android:textAppearanceMedium"
android:gravity="center" />
</LinearLayout>
</LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
Where I have to make change to get it done ?

set this background to the LinearLayout containing the textViews
<item>
<shape android:shape="rectangle">
<solid android:color="#color/colorPrimary" />
<corners android:bottomLeftRadius="cardview_corner_radius_value"
android:bottomRightRadius="cardview_corner_radius_value" />
</shape>
</item>
and add background of TextView as transparent

You have to make selector for this in drawable folder.
<?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="#color/more" />
<dotted android:color="#00FF0000" />
<padding android:bottom="1dp"/>
</shape>
</item>
</layer-list>
Then set background to your view. Use this
android:background="#drawable/corner_selector"
instead of
android:background="#color/more"

make a file rounded_border.xml in drawable folder
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<stroke
android:width="1dp"
android:color="#color/common_border_color" />
<solid android:color="#fff" />
<padding
android:left="1dp"
android:right="1dp"
android:top="1dp" />
<corners android:radius="5dp" />
</shape>
and keep it as a background of linear layout
<LinearLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="horizontal"
android:layout_marginTop="5dp"
android:background="#drawable/rounded_border"
android:layout_weight="1">

1. make button.xml file and put it in drawable folder
<?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" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#5e7974" />
<gradient android:angle="-90" android:startColor="#345953" android:endColor="#689a92" />
</shape>
</item>
<item android:state_focused="true">
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#5e7974" />
<solid android:color="#58857e"/>
</shape>
</item>
<item >
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#5e7974" />
<gradient android:angle="-90" android:startColor="#8dbab3" android:endColor="#58857e" />
</shape>
</item>
</selector>
2. then change your xml background of Linearlayout
android:background="#color/more"
to
android:background="#drawable/button"

Try with this simplest way to do this your Layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:id="#+id/btn"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/btnbackground"
android:layout_margin="20dp"
android:text="My Profile"
/>
</LinearLayout>
after that make a xml in drawable folder btnbackground.xml
<?xml version="1.0" encoding="UTF-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/llabeforeclick3"
android:state_pressed="true"/>
<item android:drawable="#drawable/llaafterclick3"/>
</selector>
then make another llabeforeclick3.xml in drawable directory
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#19384A" >
</solid>
<corners
android:bottomLeftRadius="10dp"
android:bottomRightRadius="10dp"
android:topRightRadius="10dp"
android:topLeftRadius="10dp" />
<stroke
android:width="0dp"
android:color="#19384A" />
<padding
android:left="4dp"
android:top="4dp"
android:right="4dp"
android:bottom="4dp"
android:color="#19384A" />
</shape>
after that make another xml llaafterclick3.xml in drawable
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
//background color
<solid android:color="#204A60" >
</solid>
<corners
android:bottomLeftRadius="10dp"
android:bottomRightRadius="10dp"
android:topRightRadius="10dp"
android:topLeftRadius="10dp" />
//before clicked
<gradient
android:angle="45"
android:centerColor="#204A60"
android:centerX="20"
android:centerY="20"
android:endColor="#204A60"
android:gradientRadius="25"
android:startColor="#204A60" />
</shape>
if some buddy wants to make more rounded corners then use to increase size of
android:bottomLeftRadius="10dp"
android:bottomRightRadius="10dp"
android:topRightRadius="10dp"
android:topLeftRadius="10dp"
That solve here your color code is depends on you you need to put color code only and radious.

How to change the height of a switch widget?

I want to have my switch widget larger and so I have to change the height of the switch.
But I have no solution to this.
I looked at this question: Change height of switch
And I made a drawable like this:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" android:width="0dp" android:height="30dp">
<solid android:color="#FF4444" />
</shape>
Then I setted my switch like this:
<Switch
android:id="#+id/sw_trackLiveData"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/tv_liveData"
android:layout_alignRight="#+id/btn_stoptrip1"
android:layout_alignLeft="#+id/btn_stoptrip1"
android:layout_marginTop="10dp"
android:thumbTextPadding="25dp"
android:switchMinWidth="56dp"
android:track="#drawable/roundedbutton"
android:layout_centerHorizontal="true"
android:textSize="20dp" />
But it doesnt work. I do something wrong. Can anyone give me an example how to do right? Or can anyone guide me through this?

Change your roundedButton.xml like that:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<size
android:height="20dp"
android:width="56dp" />
<solid android:color="#FF4444" />
</shape>

Change your switch Selector to below in drawable (custom_selector.xml)
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_checked="true">
<shape
android:shape="rectangle"
android:visible="true"
android:dither="true"
android:useLevel="false">
<gradient
android:startColor="#color/colorAccent"
android:endColor="#color/colorAccent"
android:angle="270"/>
<corners
android:radius="20dp"/>
<size
android:width="37dp"
android:height="37dp" />
<stroke
android:width="4dp"
android:color="#0000ffff"/>
</shape>
</item>
<item android:state_checked="false">
<shape
android:shape="rectangle"
android:visible="true"
android:dither="true"
android:useLevel="false">
<gradient
android:startColor="#android:color/white"
android:endColor="#android:color/white"
android:angle="270"/>
<corners
android:radius="20dp"/>
<size
android:width="37dp"
android:height="37dp" />
<stroke
android:width="4dp"
android:color="#0000ffff"/>
</shape>
</item>
</selector>
and Create Track in drawable (custom_track.xml)
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
android:visible="true"
android:dither="true"
android:useLevel="false">
<gradient
android:startColor="#color/card_background"
android:endColor="#color/card_background"
android:angle="270"/>
<corners
android:radius="20dp"/>
<size
android:width="50dp"
android:height="26dp" />
</shape>
And in Xml file :
<Switch
android:id="#+id/switch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginRight="16dp"
android:textOff="OFF"
android:scaleX="2"
android:scaleY="2"
android:textOn="ON"
android:thumb="#drawable/customswitchselector"
android:track="#drawable/custom_track" />

just change
android:layout_width="wrap_content"
android:layout_height="wrap_content"
to
android:layout_width="200dp"
android:layout_height="100dp"

how to show dash linebelow text view

this is my code below which show dash line on center of textview i want to show below the textview like this:
How can I change this to show below the textview dash line
<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/apprentTemp"
android:textColor="#000000"
android:background="#drawable/dotted"
android:paddingLeft="10dp"
android:gravity="left"/>
<TextView
android:id="#+id/localTime"
android:textColor="#000000"
android:background="#drawable/dotted"
android:gravity="center"/>
</TableRow>
<---- dashed.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line">
<stroke
android:color="#000000"
android:dashWidth="5px"
android:dashGap="5px" />
</shape>

use
android:drawableBottom="#drawable/dotted"
instead
android:background="#drawable/dotted"
EDIT:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:left="-5dp"
android:right="-5dp"
android:top="-5dp">
<shape
android:shape="rectangle">
<stroke
android:width="1dp"
android:dashGap="5dp"
android:dashWidth="5dp"
android:color="#android:color/black" />
</shape>
</item>
</layer-list>

Try this
dashed.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="line" >
<stroke
android:dashGap="2dip"
android:dashWidth="2dip"
android:color="#android:color/black" />
<size android:width="60dp"
android:height="6dp"/>
</shape>
then use
android:drawableBottom="#drawable/dashed"
in your TextView
instead of
android:background="#drawable/dotted"
Output:

This is how i did it.Little modifications and worked.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:gravity="center_vertical"
>
<shape
android:shape="line">
<stroke
android:width="1dp"
android:dashGap="0dp"
android:dashWidth="5dp"
android:color="#color/statusLight" />
</shape>
</item>
Just add android:dashGap to whatever value you desire.

If you want to show the dashed line in the center of the view then use the below code. like -------- Or continue with ----------
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:left="-5dp"
android:right="-5dp"
android:gravity="center_vertical">
<shape
android:shape="line">
<stroke
android:width="1dp"
android:dashGap="2dp"
android:dashWidth="5dp"
android:color="#android:color/darker_gray" />
</shape>
</item>

Try this
<TextView
android:id="#+id/total"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="right"
android:text="TextView"
android:drawableBottom="#drawable/dividerline"/>
Make one xml as below
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<size
android:height="1dp"
android:width="70dp" />
<solid android:color="#android:color/black" />
</shape>
