How to put border on button and click effect?

I have this button XML, which has transparent background and when clicked, the color changes, so that it shows a "click effect".
Drawable XML:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- press-->
<item android:drawable="#android:color/transparent" android:state_pressed="false" />
<!-- focused-->
<item style="#style/AppTheme" android:drawable="#color/color_primary" android:state_pressed="true" />
<!-- normal-->
<item android:drawable="#android:color/transparent" />
</selector>
My question is, how to put border on this button? Or an XML example so you have the same result. Thank you!

create a drawable, similar to this, selected.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#ff0000"/>
<stroke
android:width="1dp"
android:color="#00ff00" />
</shape>
then change this line
<item
style="#style/AppTheme"
android:drawable="#color/color_primary"
android:state_pressed="true" />
to
<item
style="#style/AppTheme"
android:drawable="#drawable/selected"
android:state_pressed="true" />
the solid is the background color and the border is the stroke, you can create drawables that are used in the diferent states of the selector

You can do something like this:
1. First create a drawable file like this:
<shape android:shape="rectangle">
<!--apply button background transparent, full opacity-->
<solid android:color="#00ffffff"/>
<!--make button border solid color, nontransparent-->
<stroke android:color="#stroke color" android:width="2dp"/>
<corners android:radius="2dp"/>
</shape>
then in your provided code replace these lines:
<!-- press-->
<item android:drawable="path to above drawable" android:state_pressed="false" />
<!-- focused-->
<item style="#style/AppTheme" android:drawable="#color/color_primary" android:state_pressed="true" />
<!-- normal-->
<item android:drawable="path to above drawable" />
as
<!-- press-->
<item android:drawable="path to above drawable" android:state_pressed="false" />
<!-- focused-->
<item style="#style/AppTheme" android:drawable="#color/color_primary" android:state_pressed="true" />
<!-- normal-->
<item android:drawable="path to above drawable" />

Changing size of a shape in android xml

I'm trying to change the size of a oval shape with the following code:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval"
android:thickness="70dp">
<solid android:color="#color/button_pressed" />
<size android:height="80dp"
android:width="80dp"/>
</shape>
But it doesn't change the size a bit. What am I doing wrong?
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_selected="true"
android:drawable="#drawable/circle" />
<item android:state_focused="true"
android:drawable="#drawable/circle" />
<item android:drawable="#android:color/transparent" />

Android code to change button color on click and back to original color

I want to change the color of button on clicking it and when it is about to move on to next activity its color should be set to original color. In short it should highlight the button clicked by changing the color and back to same color.

use button background as in xml :
my_button_selector.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="#color/red"/> <!-- pressed -->
<item android:state_focused="true" android:drawable="#color/blue"/> <!-- focused -->
<item android:drawable="#color/black"/> <!-- default -->
</selector>
Create colors.xml file at res/values folder:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="black">#000</color>
<color name="blue">#00f</color>
<color name="red">#f00</color>
</resources>

mybutton.xml place this file in drawable folder
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content">
<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>
change the colours according to your needs.
Then in your activity xml screen and the following code in place of Button
<Button
android:id="#+id/button1"
android:background="#drawable/mybutton"
android:layout_width="200dp"
android:layout_height="126dp" />

drawable/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= "#000000" />
<item android:drawable="#000000" />
</selector>
color/color.xml
<?xml version="1.0" encoding="utf-8" ?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:color= "#000000" />
<item android:color="#4b14b1" />
</selector>
button.setBackgroundResource(R.drawable.background)
button.setTextColor(R.color.color)

You just need to set selector of button in your layout file.
<Button
android:id="#+id/button1"
android:background="#drawable/selector_xml_name"
android:layout_width="200dp"
android:layout_height="126dp"
android:text="Hello" />
and done.
Edit
Following is button_effect.xml file in drawable directory
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/numpad_button_bg_selected" android:state_selected="true"></item>
<item android:drawable="#drawable/numpad_button_bg_pressed" android:state_pressed="true"></item>
<item android:drawable="#drawable/numpad_button_bg_normal"></item>
</selector>
In this, you can see that there are 3 drawables, you just need to place this button_effect style to your button, as i wrote above. You just need to replace selector_xml_name with button_effect.
Check out This link.

You need to create a selector in drawable, lots of solutions available.
Follow the below :
1.) Create xml file button_selector in drawable folder :
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/numpad_button_bg_selected" android:state_selected="true"></item>
<item android:drawable="#drawable/numpad_button_bg_pressed" android:state_pressed="true"></item>
<item android:drawable="#drawable/numpad_button_bg_normal"></item>
</selector>
2.) Open you layout and apply this xml selector file on your button:
<Button
android:id="#+id/btnClick"
android:background="#drawable/button_selector"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

Selector.xml is not working when clicked on the image button

I use the following selector to change image of image button, when I click on it. But this does not work most of the times. Only for few buttons it works. Don't know what the cause here is
mapselector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Button Pressed -->
<item android:state_focused="true" android:state_pressed="true"
android:drawable="#drawable/mapiconover"/>
</selector>
And in the button,
Am doing like this,
<ImageButton
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:id="#+id/btnMap" android:layout_centerInParent="true" android:src="#drawable/mapselector"
android:background="#drawable/map" android:scaleType="fitXY"
android:layout_alignParentBottom="true">
</ImageButton>
but still image is not changing when I click.
Any guess for this?

you have create like this in the ImageButton xml
create xml file using the button image like this
<?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/backbutton" />
<item
android:drawable="#drawable/closebutton" />
</selector>
add that xml file as background for IMageButton
<ImageButton
android:layout_height="50px"
android:layout_width="50px"
android:id="#+id/settings"
android:background="#drawable/settings_button" //setting_button in
the xml file
android:text="Settings"/>

Not sure if this will work but you could try changing your selector to this:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Button Pressed -->
<item android:state_focused="true" android:state_pressed="true"
android:drawable="#drawable/mapiconover"/>
<item android:drawable="#drawable/map" />
</selector>
And your image button to this:
<ImageButton
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:id="#+id/btnMap"
android:layout_centerInParent="true"
android:background="#drawable/mapselector"
android:scaleType="fitXY"
android:layout_alignParentBottom="true">
</ImageButton>

I had the same problem. For me it was because of
android:state_xxxx
conflict. It solved by clarifying the conditions between enabled and pressed. I used the following code to get different states between press and normal state:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="true" android:state_pressed="false" >
<shape
android:shape="rectangle">
<gradient android:startColor="#1094ff"
android:endColor="#7eb6e3"
android:angle="270" />
<corners android:radius="#dimen/fab_margin" />
<stroke android:width="2px"
android:color="#505050" />
</shape>
</item>
<item android:state_pressed="true" android:state_enabled="true">
<shape
android:shape="rectangle">
<gradient android:startColor="#0075d4"
android:endColor="#0070cb"
android:angle="270" />
<corners android:radius="#dimen/fab_margin" />
<stroke android:width="2px"
android:color="#ff0000" />
</shape>
</item>
<item android:state_enabled="false" >
<shape
android:shape="rectangle">
<gradient android:startColor="#b9b9b9"
android:endColor="#848484"
android:angle="270" />
<corners android:radius="#dimen/fab_margin" />
<stroke android:width="2px"
android:color="#505050" />
</shape>
</item>
</selector>
This example uses different gradient and stroke for different states. You can also use your drawable instead. Just create a file like "mybutton.xml" in your drawable folder. then set the background property of your button like this:
android:background="#drawable/mybutton"
I hope it be helpful.

Problem setting ListView selector color when pressed

I have the following ListView, and have followed the answer from this SO Question w/ no luck:
Android ListView Selector Color
<ListView android:layout_width="fill_parent"
android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ARListView"
android:background="#drawable/transparent_background"
android:cacheColorHint="#00000000"
android:listSelector="#drawable/ar_selector"
android:drawSelectorOnTop="true">
Here is my ar_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false" android:state_focused="true"
android:drawable="#android:color/transparent" />
<item android:state_pressed="true"
android:drawable="#color/solid_red" />
<item android:state_focused="true"
android:drawable="#android:color/transparent" />
</selector>
When I press down on a ListViewItem nothing appears.

Sheehan Alam, use this code:-
list_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_selected="false"
android:state_pressed="false"
android:drawable="#drawable/gradient_bg" />
<item android:state_pressed="true"
android:drawable="#drawable/gradient_bg_hover" />
<item android:state_selected="true"
android:state_pressed="false"
android:drawable="#drawable/gradient_bg_hover" />
</selector>
gradient_bg.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#f1f1f2"
android:centerColor="#e7e7e8"
android:endColor="#cfcfcf"
android:angle="270" />
</shape>
gradient_bg_hover.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#18d7e5"
android:centerColor="#16cedb"
android:endColor="#09adb9"
android:angle="270" />
</shape>
