SeekBar thumb states drawables not working correctly, not animating either

I'm working for Android API 16+, testing on an API 21 device.
I'm using a SeekBar programmatically. I've got the following thumb Drawable defined in XML:
<?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="oval">
<solid android:color="#color/my_red" />
<size android:width="18dp" android:height="18dp" />
</shape>
</item>
<item android:state_selected="true">
<shape android:shape="oval">
<solid android:color="#color/my_red" />
<size android:width="12dp" android:height="12dp" />
</shape>
</item>
<item android:state_focused="true">
<shape android:shape="oval">
<solid android:color="#color/my_red" />
<size android:width="10dp" android:height="10dp" />
</shape>
</item>
<item> <!-- state_default -->
<shape android:shape="oval">
<solid android:color="#color/my_red" />
<size android:width="0dp" android:height="0dp" />
</shape>
</item>
</selector>
I apply this drawable using SeekBar.setProgressDrawable. What happens is that the thumb properly uses the default state drawable (as far as I know, the thumb does not show) but never changes. I tried to use setSelected, requestFocus and to just drag the thumb, but it does not change.
What am I missing?
EDIT: Based on a suggestion by #pskink, I changed my XML to try this:
seekbar_thumb_shape.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#color/my_red" />
<size android:width="20dp" android:height="20dp" />
</shape>
seekbar_thumb.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<inset android:drawable="#drawable/seekbar_thumb_shape"
android:insetTop="0dp"
android:insetRight="0dp"
android:insetBottom="0dp"
android:insetLeft="0dp" />
</item>
<item android:state_selected="true">
<inset android:drawable="#drawable/seekbar_thumb_shape"
android:insetTop="5dp"
android:insetRight="5dp"
android:insetBottom="5dp"
android:insetLeft="5dp" />
</item>
<item android:state_focused="true">
<inset android:drawable="#drawable/seekbar_thumb_shape"
android:insetTop="5dp"
android:insetRight="5dp"
android:insetBottom="5dp"
android:insetLeft="5dp" />
</item>
<item> <!-- state_default -->
<inset android:drawable="#drawable/seekbar_thumb_shape"
android:insetTop="10dp"
android:insetRight="10dp"
android:insetBottom="10dp"
android:insetLeft="10dp" />
</item>
</selector>
The result is extremely random. I was also expecting a small animation to happen, much like the default SeekBar animations, but it just changes drawables brutally.
My goal is just to reproduce a SeekBar close to the one of the YouTube Android App.

Ripple effect in pressed state + transparency in normal state

I would like the ImageView in the ViewGroup, when pressed, draws the ripple and this is working! But when the ViewGroup is pressed, the ImageView inside it, should remain transparent otherwise the ImageView background is visible: (that color alpha-orange, you actually see, is the ripple when pressed).
This happens only with devices API 21+. With devices API <21 I use a selector and the image background remains transparent as wanted when the ViewGroup is pressed.
layout.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="wrap_content"

android:paddingTop="#dimen/margin_top_item_field"
android:paddingBottom="#dimen/margin_bottom"

drawable/button_mini_oval.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">

<shape android:shape="oval">
<solid android:color="#color/primary_highlight" />
</shape>

<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:exitFadeDuration="#android:integer/config_shortAnimTime"
android:color="?android:colorControlHighlight">
<item android:state_pressed="true">
<shape android:shape="oval">
<solid android:color="#android:color/white" />
</shape>
</item>
<item>
<color android:color="#android:color/transparent" />
</item>
</ripple>
I tried many configurations in the ripple xml, adding a <selector> it works (see below), but if you just tap the ImageView, the ripple is not visible (the ripple animation seems cut), only if you keep pressed you see the ripple...
What is the combination to have ripple in pressed state and transparent in normal state?
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:exitFadeDuration="#android:integer/config_shortAnimTime"
android:color="?android:colorControlHighlight">
<item>
<selector>
<item android:state_pressed="true">
<shape android:shape="oval">
<solid android:color="#android:color/white" />
</shape>
</item>
<item>
<color android:color="#android:color/transparent" />
</item>
</selector>
</item>
</ripple>

Removing android:state_pressed="true", I've found 2 solutions but in both cases I lost the touch_raise animation (why?):
With masked ripple:
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:exitFadeDuration="#android:integer/config_shortAnimTime"
android:color="?android:colorControlHighlight">
<item android:id="#android:id/mask">
<selector>
<item>
<shape android:shape="oval">
<solid android:color="#android:color/white" />
</shape>
</item>
<item>
<color android:color="#android:color/transparent" />
</item>
</selector>
</item>
</ripple>
With unmasked little ripple (nicer than 1):
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:exitFadeDuration="#android:integer/config_shortAnimTime"
android:color="?android:colorControlHighlight">
<selector>
<item>
<color android:color="#android:color/transparent" />
</item>
</selector>
</ripple>
I don't know why it is sufficient to add <selector> to have a ripple on a transparent background!!! a lot of people were trying to achieve this but it wasn't the intention of Google, instead it is very useful is such situations.

With me, it works
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#color/white"
android:radius="3dp">
<item android:drawable="#drawable/transparent_ripple_button"/>
</ripple>
and a separate
transparent_ripple_button.xml
in your folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true">
<shape android:shape="rectangle">
<solid android:color="#color/black_12" />
<stroke android:width="0.2dp" android:color="#color/white" />
<corners android:radius="3dp" />
</shape>
</item>
<item android:state_pressed="true">
<shape android:shape="rectangle">
<solid android:color="#color/black_12" />
<stroke android:width="0.2dp" android:color="#color/white" />
<corners android:radius="3dp" />
</shape>
</item>
<item>
<shape android:shape="rectangle">
<solid android:color="#android:color/transparent" />
<stroke android:width="0.2dp" android:color="#color/white" />
<corners android:radius="3dp" />
</shape>
</item>
</selector>

Android switches - making thumb height larger than track height, how?

Is there any way to make the height of the thumb of a switch bigger than the track height in Android versions prior to Lollipop ?
I am essentially trying to create a material design-like switch widget in Kitkat (and older versions- the problem here is the thumb by default 'fits' inside the track). I have been working on this for quite some time now but I can't seem to arrive at the correct design.
I followed the solutions on this SO post: How to change the size of a Switch Widget.
Any suggestions or a solution would be most appreciated.

I added a transparent stroke to my track drawable shape which results in a padding around the track:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#color/track_color"/>
<size android:height="#dimen/track_height" />
<size android:width="#dimen/track_width" />
<!-- results in the track looking smaller than the thumb -->
<stroke
android:width="6dp"
android:color="#00ffffff"/>
</shape>

Yup
I solved this
<android.support.v7.widget.SwitchCompat
android:id="#+id/mySwitch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textOn="ON"
android:textOff="OFF"
style="#style/Color1SwitchStyle"
android:text="" />
This is My Color1SwitchStyle
<style name="Color1SwitchStyle">
<item name="android:thumb">#drawable/customswitchselector</item>
<item name="android:track">#drawable/my_custom_track</item>
//when use Switch in xml file
<item name="track">#drawable/my_custom_track</item>
//when use android.support.v7.widget.SwitchCompat in xml
</style>
*Hear is my customswitchselector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_checked="true"
android:drawable="#drawable/on" >
<shape
android:shape="rectangle"
android:dither="true"
android:useLevel="false"
android:visible="true">

Thanks stevenp without your comment i cannot solve this

Adding top and bottom inset in the 'track' drawable works for me. android:bottom="5dp" android:top="5dp"
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:bottom="5dp"
android:top="5dp">
<shape>
<corners android:radius="15dp" />
<solid android:color="#android:color/transparent" />
<stroke
android:width="2dp"
android:color="#EEEEEE" />
</shape>
</item>
<androidx.appcompat.widget.SwitchCompat
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:track="#drawable/switch_track_drawable" />

The solution I came up with is just to use for the track a shape that is a line instead of a rectangle, and set the width explicitly in its stroke.
For example if the switch is defined as follows:
<android.support.v7.widget.SwitchCompat
android:id="#+id/my_switch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:track="#drawable/switch_track"
app:theme="#android:style/Theme.DeviceDefault.Light" />
The in the switch_track.xml drawable use a line shape with whatever width you desire:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_checked="false" >
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="line" >
<stroke android:color="#50bbb9bf" android:width="5dp"/>
</shape>
</item>
<item android:state_checked="true">
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="line">
<stroke android:color="#5000b6de" android:width="5dp"/>
</shape>
</item>
</selector>

How Do Create This Type Of CheckBox In Android

How to create this type of checkbox in android when it pressed. I tried . May I know what is the correct way to achieve my objective?Maybe this question too basic, but i did't find any suitable solution.Please Help me out.
I want to create Like this
When it unchecked it will looks like :
Here is my XML code for checkbox:
<CheckBox
android:id="#+id/checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:button="#drawable/custom_checkbox"/>
Here is custom_checkbox.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true"
android:drawable="#drawable/checked" />
<item android:state_pressed="true"
android:drawable="#drawable/checked" />
<item android:drawable="#drawable/unchecked" />
</selector>
Here is checked.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#54d66A" android:endColor="#54d66A" android:angle="270"/>
<stroke android:width="4px" android:color="#ffc0c0c0" />
<size android:height="20dp" android:width="20dp"/>
</shape>
Here is my output:

You need to create a drawable with layer-list with two items as rectangle shape . one for the background and other as stroke with some margin.
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<gradient android:startColor="#54d66A" android:endColor="#54d66A" android:angle="270"/>
<size android:height="20dp" android:width="20dp"/>
</shape>
</item>
<item android:bottom="2dp" android:left="2dp" android:right="2dp" android:top="2dp">
<shape android:shape="rectangle" >
<stroke android:width="2dp" android:color="#ffc0c0c0" />
</shape>
</item>
</layer-list>
And , set this drawable as state_checked background.

How to apply shape and selector simultaneously for Button?

I have applied a shape for a button like:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<gradient android:startColor="#DD000000" android:endColor="#DD2d2d2d" android:angle="90"></gradient>
<corners android:radius="15dip"></corners>
</shape>
Now I want to use a selector like:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/active"
android:state_pressed="true" />
<item android:drawable="#drawable/passive"/>
for this Button as well. Is it possible ...???

use this way:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape>.......</shape>
</item>
..........
..........
</selector>

Detailed to the point answer
Create a color resource in
res/values/colors.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<item name="yellow" type="color">#F7B500</item>
<item name="yellow_dark" type="color">#AC7E00</item>
<integer-array name="androidcolors">
<item>#color/yellow</item>
<item>#color/yellow_dark</item>
</integer-array>
</resources>
Create a drawable at
res/drawable/bg_yellow_round.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#color/yellow" />
<stroke
android:width="2dp"
android:color="#color/yellow" />
<corners
android:bottomLeftRadius="20dp"
android:bottomRightRadius="20dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp" />
</shape>
Create another drawable, you want for transition at same place and name it
res/drawable/bg_yellow_dark_round.xml
<solid android:color="#color/yellow_dark" />
<stroke
android:width="2dp"
android:color="#color/yellow_dark" />
<corners
android:bottomLeftRadius="20dp"
android:bottomRightRadius="20dp"
android:topLeftRadius="20dp"
android:topRightRadius="20dp" />
Now create a color state list at
res/color/btn_selector_yellow.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" android:exitFadeDuration="#android:integer/config_shortAnimTime">
<item android:drawable="#color/yellow" android:state_focused="true" android:state_pressed="false"/>
<item android:drawable="#drawable/bg_yellow_dark_round" android:state_pressed="true"/>
<item android:drawable="#drawable/bg_yellow_round"/>
</selector>
Now set it to your button as following
<Button
android:id="#+id/button1"
android:layout_width="248dp"
android:layout_height="44dp"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="10dp"
android:layout_marginTop="20dp"
android:background="#color/btn_selector_yellow"
android:text="AZ_ is so cool" />
Now this will do transition from
to
.

shape.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/star_off"/>
<corners android:radius="5dp"/>
<padding android:left="0dp" android:top="0dp" android:right="0dp" android:bottom="0dp" />
</shape>
selector.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android" android:exitFadeDuration="#android:integer/config_mediumAnimTime">
<item android:drawable="#color/tab_focused" android:state_focused="true" android:state_pressed="false"/>
<item android:drawable="#color/tab_pressed" android:state_pressed="true"/>
<item android:drawable="#drawable/shape"/>
</selector>

You can also create a shape that is using a selector inside. If your shape is just changing its color in different states, this is a lot cleaner.
color/color_selector.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:color="#color/blue_dark" android:state_pressed="true" />
<item android:color="#color/blue_light" />
</selector>
drawable/shape.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/color_selector" />
<corners android:bottomLeftRadius="6dip" android:bottomRightRadius="6dp" />
<padding android:bottom="0dip" android:left="0dip" android:right="0dip" android:top="0dip" />
</shape>

Well I know it's way too late
But here is a solved example
<TextView
android:id="#+id/txt_out_going_calls"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="04dp"
android:layout_weight="1"
android:background="#drawable/header_text_view_selector"
android:gravity="center"
android:text="#string/outgoing_calls_tab_button_text"
android:textColor="#color/home_text_color" />
and my header_text_view_selector
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true">
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/home_fragment_tab_color_selected"/>
<corners android:radius="25dip" />
<padding android:bottom="08dip" android:left="9dip" android:right="9dip" android:top="08dip" />
</shape>
</item>
<item android:state_selected="false">
<shape>
<solid android:color="#color/home_fragment_tab_color_simple"/>
<corners android:radius="25dip" />
<padding android:bottom="08dip" android:left="9dip" android:right="9dip" android:top="08dip" />
</shape>
</item>
</selector>
So basically i m creating a rounded textview with selector. Here i m handling only state_selected and not_selected. Hope it helps

This is my way, and it works!
<item android:state_pressed="true">
<shape android:shape="oval">
<gradient android:centerX=".6"
android:centerY=".40"
android:endColor="#color/colorPrimary"
android:gradientRadius="20"
android:startColor="#color/colorPrimary"
android:type="radial" />
<stroke android:width="1dp"
android:color="#FFFFFF" />
<size android:width="55dp"
android:height="55dp" />
</shape>
</item>
<item android:state_focused="false">
<shape android:shape="oval">
<gradient android:centerX=".6"
android:centerY=".40"
android:endColor="#android:color/transparent"
android:gradientRadius="20"
android:startColor="#android:color/transparent"
android:type="radial" />
<stroke android:width="1dp"
android:color="#FFFFFF" />
<size android:width="55dp"
android:height="55dp" />
</shape>
</item>

My example is a circle button with state_pressed.
code bellow:
<?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="oval">
<solid android:color="#color/light_primary_color" />
</shape>
</item>
<item>
<shape android:shape="oval">
<solid android:color="#color/accent_color" />
</shape>
</item>
</selector>

Use your shape name as you use any image and use it selector as you use image. Try out you will not face any problem. Is that what you were asking?

To be more reusable, you can set states on single properties. Avoid duplicating your shapes
<selector
xmlns:android="http://schemas.android.com/apk/res/android"
>
<item>
<shape android:shape="rectangle" >
<corners android:radius="5dp"/>
<solid
android:state_enabled="false"
android:color="#color/transparent"
/>
<solid
android:state_enabled="true"
android:color="#color/background"
/>
<stroke
android:width="#dimen/dividerHeight"
android:color="#color/dividerLight"
/>
</shape>
</item>
</selector>
I was able to set background programmatically once disabled using this method.
