Not able to set gradient background of floating action button

I am trying to set the background of the floating action button as a gradient. I have already seen many solutions but none of them are working out for me. whatever I try it is showing me a black action button. I have tried setting the background to colour but that also didn't work. I am trying to create the bottom navigationBar.
My code
<?xml version="1.0" encoding="utf-8"?>

In your theme.xml Create a style
<style name="Floating" parent="Widget.Design.FloatingActionButton">
<!---rest of your style-->
<item name="android:foreground">#drawable/gradient</item>
</style>
and in your FloatingActionButton apply this style :
<com.google.android.material.floatingactionbutton.FloatingActionButton
style="#style/Floating"
android:id="#+id/fab_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

UPDATE:
to center the icon: in API 23 and above:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">

<item
android:drawable="#drawable/common_full_open_on_phone"
android:gravity="center"
android:width="24dp"
android:height="24dp">
</item>
</layer-list>
and for API 23 and less :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<gradient
android:angle="45"
android:endColor="#cd337b"
android:startColor="#f09448" />
</shape>
</item>
<item

android:top="15dp"
android:right="15dp"
android:left="15dp"
android:bottom="15dp" />

Android/Spinner: Remove padding to the right of the arrow

I'm using a spinner in a relative layout with a couple of other layout elements (layout-v21):
<Spinner
android:id="#+id/spinner"
android:layout_width="155dp"
android:layout_height="34dp"
android:layout_alignBottom="#+id/textList"
android:layout_alignTop="#+id/textList"
android:layout_alignParentEnd="true"
android:layout_marginLeft="5dp"
android:layout_marginRight="0dp"
android:layout_toEndOf="#+id/textList"
android:paddingRight="1dp"/>
This sets the distance to where the parent layout ends:
android:layout_marginRight="0dp"
android:layout_alignParentEnd="true"
This sets how close the choice items inside the spinner can get to the left of the arrow (right padding of the text):
android:paddingRight="1dp"
But is there a way to get rid of (or at least make smaller) the unnecessary space/padding that is to the right of the arrow but still within the spinner layout element (so I can then use more space on the left without changing the size of the spinner)?
This is what I'm talking about:
Edit: Here's the code for the RelativeLayout:
<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"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.mycompany.myapp.MainActivity"
android:backgroundTint="#000000"
android:focusableInTouchMode="true">

It work for me :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

android:paddingBottom="10dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="10dp"
android:backgroundTint="#000000"
android:focusableInTouchMode="true">
<Spinner
android:id="#+id/spinner"
android:layout_width="155dp"
android:layout_height="34dp"
style="#style/spinner_style"
android:layout_alignParentEnd="true"
android:layout_marginLeft="5dp"
android:layout_marginRight="0dp"
android:paddingRight="1dp"/>

Change edittext backgroundTint Color

Here is my editext, i want to change bottom line color of edittext. i use android:backgroundTint but its only work in API 21 and above it.
<EditText
android:id="#+id/password"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="20dp"
android:backgroundTint="#color/edittintcolor"
android:drawableLeft="#drawable/lock"
android:hint=" Password"
android:padding="15dp"
android:textColor="#color/edittintcolor"
android:textColorHint="#color/edittintcolor"
android:textSize="18sp"
android:typeface="serif" />
I want to change this color using XML or style not in java code

bg.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#FDEEF4" />
<corners
android:radius="15dp" />
<stroke android:width="1dip" android:color="#F9966B" />
<EditText
android:id="#+id/password"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="#drawable/bd=g"
android:hint="#string/password"
android:inputType="textPassword" >
</EditText>

Create a drawable xml for your edittext background.. Use this following 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="#android:color/transparent" />
<!--background color of box-->
</shape>
</item>
<item
android:left="-2dp"
android:right="-2dp"
android:top="-2dp">
<shape>
<solid android:color="#android:color/transparent" />
<stroke
android:width="1dp"
android:color="#android:color/white" />
<!-- color of edittext line -->
</shape>
</item>
</layer-list>
and set that drawable xml as your edittext background. :)

use command like below in edit text
<EditText
android:id="#+id/password"
android:layout_width="200dp"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:background="#drawable/edittextborder"
android:hint="#string/password"
android:inputType="textPassword" >
<requestFocus />
</EditText>
then proceed with below code inside drawable folder
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#FDEEF4" />
<corners
android:radius="15dp" />
<stroke android:width="1dip" android:color="#F9966B" />
EDEEF4 represents the tint color

We can achieve by using two ways,
Method 1:
We can design background image using selector drawable,
create backgroundEditText.xml in drawable,
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_window_focused="false"
android:state_enabled="true"
android:drawable="#drawable/textfield_default" />
<item
android:state_window_focused="false"
android:state_enabled="false"
android:drawable="#drawable/textfield_disabled" />
<item
android:state_pressed="true"
android:drawable="#drawable/textfield_pressed" />
<item
android:state_enabled="true"
android:state_focused="true"
android:drawable="#drawable/textfield_selected" />
<item
android:state_enabled="true"
android:drawable="#drawable/textfield_default" />
<item
android:state_focused="true"
android:drawable="#drawable/textfield_disabled_selected" />
<item
android:drawable="#drawable/textfield_disabled" />
textfield_pressed.9.png

textfield_selected.9.png

We need to set backgroundEditText for EditText in layout file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<EditText
android:id="#+id/edit1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/edit1_text"
android:inputType="text"
android:background="#drawable/edit_text"
/>
</LinearLayout>
[![Final Output ][6]][6]
Method 2:
Using android.support.v4 support library, we can give backward compatibility.

You can use this site to generate your own EditText style.
Generate drawable and set it as background, like:
android:background="#drawable/generated_theme_edit_text"

How to make a "L" shaped edit text drawable selector in android

I am trying to create a EditText as below
Question:
How can i write a selector for this and set as background
I do not want to place a image

You need to use a <layer-list> to accomplish what you want. Taken from this answer
res/drawable/text.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="#000000" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<solid android:color="#000000" />
</shape>
</item>
<item android:bottom="3px" android:left="3px">
<shape android:shape="rectangle">
<solid android:color="#FFFFFF" />
</shape>
</item>
</layer-list>
res/layout/activity_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<EditText
android:id="#+id/editText1"
android:background="#drawable/text"
android:layout_width="170dp"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="30dp"
android:ems="10"
android:gravity="center_horizontal"
android:padding="2dp"
android:password="true" />
</RelativeLayout>
Expected Output:

This would work
Layout
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="textEmailAddress"
android:ems="10"
android:layout_margin="5dp"
android:paddingLeft="5dp"
android:hint="Email"
android:background="#drawable/test_edit"
android:id="#+id/editText" />
Layer_list
<item android:drawable="#color/lightBlue"/>
<item android:drawable="#color/darkBlue" android:left="2dp" android:bottom="2dp" />
Color
darkBlue #ff1ca9ff
lightBlue #ffb6f1ff

Not sure if this may help you but I would just create through the xml and use the Android 4.4 theme to style it L shaped. I would then set the background color to blue. This is how it done:
Create the color.xml file, to enter the color values you need.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="dodgerblue">#1E90FF</color>
<color name="lightskyblue_1">#B0E2FF</color>
</resources>
Then, in your EditText, set the color as follows
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="asdsadasdasd"
android:textColor="#color/lightskyblue_1"
android:background="#color/dodgerblue"
/>
If you need more colors, here is a useful link.
Hope this helps :)

how to make card list in android

I was looking for some ListView, styling techniques and I found this one Post-How to make card List, I wanted the ListItems to be just like this :
list_item_background.xml is :
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle"
android:dither="true">
<corners android:radius="2dp"/>
<solid android:color="#ccc" />
</shape>
</item>
<item android:bottom="2dp">
<shape android:shape="rectangle"
android:dither="true">
<corners android:radius="2dp" />
<solid android:color="#android:color/white" />
<padding android:bottom="8dp"
android:left="8dp"
android:right="8dp"
android:top="8dp" />
</shape>
</item>
I have implemented that in my RowOfListView.xml like :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="#dimen/ten"
android:background="#drawable/list_item_background" >
<ImageView
android:id="#+id/imageView_in_row"
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_alignParentLeft="true"
android:layout_alignTop="#+id/row_member_name"
android:layout_marginBottom="#dimen/ten"
android:layout_marginLeft="#dimen/five"
android:background="#drawable/rectangle"
android:contentDescription="#string/image"
android:src="#drawable/member" />
<TextView
android:id="#+id/row_member_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="#dimen/ten"
android:layout_marginRight="#dimen/ten"
android:layout_marginTop="#dimen/ten"
android:layout_toRightOf="#+id/imageView_in_row"
android:ellipsize="end"
android:text="Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
.
.
.
</RelativeLayout>
But I'm getting this one :
unable to get that margin between Items of ListView as in prior picture, where I should set that margin.

You can try like this for listview row xml:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/outer"
style="#style/CardOuterStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/dialog_white"
android:orientation="vertical" >
//your fields here
</LinearLayout>
</FrameLayout>
and CardOuterStyle
<style name="CardOuterStyle">
<item name="android:paddingLeft">5dp</item>
<item name="android:paddingRight">5dp</item>
<item name="android:paddingTop">5dp</item>
</style>

You should set the dividerHeight of the ListView as :
<ListView android:id="#+id/MyListView"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:divider="#android:color/transparent"
android:dividerHeight="#dimen/ten"/>
Alternatively, you may also give padding in your relative layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="#dimen/ten"
android:background="#drawable/list_item_background"
android:paddingTop="#dimen/five"
android:paddingBottom="#dimen/five" >
