how to design a spinner with border and divider between each item

I have a spinner somewhere in my app and need to provide a border and divider between each item, i did the following everything seem good, but when i click on it, in drop down list, there is no sign of that border anymore, i need that border around the drop down list, here is what i did :
I want my spinner to look like this:
but instead it's looking like this
.
here is spinner in layout activity :
<Spinner
android:id="#+id/cities_spinner"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_gravity="center"
android:layout_marginStart="20dp"
android:layout_marginTop="156dp"
android:layout_marginEnd="20dp"
android:background="#drawable/spinner_border"
android:entries="#array/cities"
android:popupElevation="0dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.487"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
</Spinner>
here is spinner border :
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#color/white" />
<corners android:radius="40dp" />
<stroke
android:color="#707070"
android:width="1dp" />
</shape>
here is text view for each spinner item :
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/textView1"
android:layout_width="250dp"
android:layout_height="wrap_content"
android:textColor="#fefcfe"
android:padding="10dp"
android:textSize="18dp"
android:background="#drawable/spinner_item_devider" />
this is spinner_item_devider :
<?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="#707070"/>
</shape>
</item>
<item android:bottom="1.5dp">
<shape android:shape="rectangle">
<solid android:color="#color/white"/>
</shape>
</item>
</layer-list>
and this is piece of java code for setting adapter :
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,R.array.cities,R.layout.spinner_text_view);
adapter.setDropDownViewResource(R.layout.spinner_text_view);
cities.setAdapter(adapter);
and also this is not showing anything in adapter, don't know why, so any help would be appriciated.

Something like this
<Spinner
android:id="#+id/cities_spinner"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_gravity="center"
...
android:dropDownVerticalOffset="40dp"
android:background="#drawable/spinner_border_top"
android:popupBackground="#drawable/spinner_border_bottom"
...
>
</Spinner>
spinner_border_top
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#color/white" />
<corners android:topLeftRadius="20dp"
android:topRightRadius="20dp"/>
<stroke
android:color="#707070"
android:width="1dp" />
</shape>
spinner_border_bottom
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"

<corners android:bottomLeftRadius="20dp"
android:bottomRightRadius="20dp"/>
<stroke
android:color="#707070"
android:width="1dp" />
</shape>
spinner_text_view_1
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#000000"
android:padding="10dp"
android:textSize="18dp"
/>
spinner_text_view
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textColor="#000000"
android:padding="10dp"
android:background="#drawable/spinner_item_divider"
android:textSize="18dp"
/>
spinner_item_divider
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:top="0dp"
android:left="-6dp"
android:right="-6dp"
android:bottom="-6dp">
<shape android:shape="rectangle">
<stroke
android:width="1dp"
android:color="#707070"/>
</shape>
</item>
</layer-list>
adapter setting
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,R.array.country_data, R.layout.spinner_text_view_1);
adapter.setDropDownViewResource(R.layout.spinner_text_view);
cities.setAdapter(adapter);

Set an xml background for linear layout and show its press effect

I want to set following xml shape as my linear layout background:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<stroke
android:width="2dp"
android:color="#D50000">
</stroke>
<solid
android:color="#android:color/transparent">
</solid>
</shape>
And I also want to show the press effect by these lines of code:
android:clickable="true"
android:focusable="true"
android:foreground="?android:attr/selectableItemBackground"
android:background="?android:selectableItemBackground"
But as you know, it is impossible to have two background for a view. So, What is the solution?

Try this:
<LinearLayout
android:layout_margin="16dp"
app:layout_constraintTop_toTopOf="parent"
android:background="#drawable/ll_background"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:onClick="doSomething"
android:padding="8dp"
android:weightSum="3">
<TextView
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Greeting" />
<TextView
android:layout_weight="2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Hello World!" />
</LinearLayout>
Then in drawable/ folder add:
button_normal.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<stroke
android:width="2dp"
android:color="#D50000">
</stroke>
</shape>
button_pressed.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid
android:color="#D50000">
</solid>
<stroke android:color="#D50000" android:width="2dp"/>
</shape>
Then create ll_background.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="#drawable/button_pressed"/>
<item android:drawable="#drawable/button_normal"/>
</selector>
Finally for ripple create drawable-v21 folder and add ll_background.xml:
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#D50000">
<item>
<shape android:shape="rectangle">
<solid android:color="#android:color/white" />
<stroke
android:color="#D50000"
android:width="1dp" />
</shape>
</item>
</ripple>
The first three files (button_normal.xml, button_pressed.xml & ll_background.xml) will be for api < 21 and the 4th (ll_background.xml) ripple will be on all other devices including api 21 and above.

Shadow text view in Android

I am trying shadow text view like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="top|center"
android:background="#drawable/gradient">
<TextView
android:layout_width="300dp"
android:layout_height="50dp"
android:text="#string/ph"
style="#style/TextBox"
android:textSize="16sp"/>
</LinearLayout>
gradient.xml
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle">
<gradient
android:endColor="#FFFFFF"
android:startColor="#FFFFFF"
android:type="linear"
android:centerColor="#E3F2FD"
android:angle="90">
</gradient>
</shape>
</item>
This code can't get my design. Is it possible to textview like my picture?

Here i tried to create same shadow as your requirement which will look like this. I know the shadow color is not blur as u want
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#drawable/shadow"
android:orientation="vertical"
android:paddingBottom="5dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/rectangle_shape"
android:padding="10dp"
android:text="Phone Number" />
</LinearLayout>
drawable/shadow.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#220000ff" />
<corners android:radius="20dp" />
</shape>
drawable/rectangle_shape.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#FFFFFF" />
<corners android:radius="20dp" />
</shape>

make xml backround_with_shadow and paste this code-
<?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="#87ceeb" />
<corners android:radius="5dp"/>
</shape>
</item>
and set xml as background of layout
<item android:right="1dp" android:left="1dp" android:bottom="2dp">
<shape
android:shape="rectangle">
<solid android:color="#android:color/white"/>
<corners android:radius="5dp"/>
</shape>
</item>
</layer-list>

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.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="0dp"
android:layout_height="?android:attr/actionBarSize"
android:background="#drawable/rounded_corner"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
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"
app:shape_arc_position="bottom">
<!-- YOUR CONTENT -->

Custom designing EditText

I have custom designed EditText
search_page.xml
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="10dp"
android:background="#E1E1E1"
android:weightSum="1" >
<TextView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".25"
android:text="City" />
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:background="#drawable/rounded_edittext"
android:layout_weight=".75" />
</LinearLayout>
rounded_edittext.xml
<?xml version="1.0" encoding="utf-8"?>
<!-- res/drawable/rounded_edittext.xml -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="10dp"
android:shape="rectangle" >
<solid android:color="#FFFFFF" />
<corners
android:bottomLeftRadius="10dp"
android:bottomRightRadius="10dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp" />
</shape>
I want to use color code #2f6699 to get a border color like an outline to the EditText text box as below:
Any ideas on how to achieve this?

Use the below code in your rounded_edittext.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#FFFFFF" />
<stroke
android:width="1dp"
android:color="#2f6699" />
<corners
android:radius="10dp"
/>
</shape>
This should work

For EditText in image above, You have to create two xml files in res-->drawable folder.
First will be "bg_edittext_focused.xml" paste the lines of code in it
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#FFFFFF" />
<stroke
android:width="2dip"
android:color="#F6F6F6" />
<corners android:radius="2dip" />
<padding
android:bottom="7dip"
android:left="7dip"
android:right="7dip"
android:top="7dip" />
</shape>
Second file will be "bg_edittext_normal.xml" paste the lines of code in it
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#F6F6F6" />
<stroke
android:width="2dip"
android:color="#F6F6F6" />
<corners android:radius="2dip" />
<padding
android:bottom="7dip"
android:left="7dip"
android:right="7dip"
android:top="7dip" />
</shape>
In res-->drawable folder create another xml file with name "bg_edittext.xml" that will call above mentioned code. paste the following lines of code below in bg_edittext.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/bg_edittext_focused" android:state_focused="true"/>
<item android:drawable="#drawable/bg_edittext_normal"/>
</selector>
Finally in res-->layout-->example.xml file in your case wherever you created your editText
you'll call bg_edittext.xml as background
<EditText
:::::
:::::
android:background="#drawable/bg_edittext"
:::::
:::::
/>

Use the below code in your rounded_edittext.xml :
<?xml version="1.0" encoding="utf-8" ?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:thickness="0dp"
android:shape="rectangle">
<stroke android:width="2dp"
android:color="#2F6699"/>
<corners android:radius="3dp" />
<gradient android:startColor="#C8C8C8"
android:endColor="#FFFFFF"
android:type="linear"
android:angle="270"/>
</shape>

android:background="#E1E1E1"
// background add in layout
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#ffffff">
</EditText>

edit_text.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#ffffff" />
<corners android:radius="5dp"/>
<stroke android:width="2dip" android:color="#color/button_color_submit" />
</shape>
use here
<EditText
-----
------
android:background="#drawable/edit_text.xml"
/>

Use a 9-patch drawable or create a Shape drawable.
