I have a fairly simple selector with two states. A light gray shade for normal and a dark gray for pressed. Code:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true">
<inset android:insetLeft="8dp"
android:insetTop="8dp"
android:insetRight="8dp"
android:insetBottom="8dp">
<shape android:shape="rectangle">
<corners android:radius="8dp" />
<solid android:color="#color/widget_gray_dark" />
<padding android:left="8dp"
android:top="8dp"
android:right="8dp"
android:bottom="8dp" />
</shape>
</inset>
</item>
<item>
<inset android:insetLeft="8dp"
android:insetTop="8dp"
android:insetRight="8dp"
android:insetBottom="8dp">
<shape android:shape="rectangle">
<corners android:radius="8dp" />
<solid android:color="#color/widget_gray_light" />
<padding android:left="8dp"
android:top="8dp"
android:right="8dp"
android:bottom="8dp" />
</shape>
</inset>
</item>
</selector>
Now I want to add the android's tint feature to it. Setting the tint attribute to any widget with this selector on pre-lollipop devices has no effect. I am using app-compact and according to its blog, it should work. Maybe I am not using it properly.
How can I set the tint?

Ripple effect goes beyond the margins of the button I put this background to. I guess it is because of this part of code:
android:top="2dp"
android:bottom="4dp"
android:left="2dp"
android:right="1dp">
which makes shadow on my button. I would like to make ripple effect only on the original size of button. How should I do this.
Also removing ripple tag crashes my app. I can add in the place of ripple, but then it does not work as I want it to.
How to solve this?
I want to have a glow effect on button (in android studio) as shown in image:
I didn't want an image for the background, so to get this effect, I have tried to do in xml file. I have added a stroke for the button and provide a shadow to the button (with same color as stroke).
I have used a linear gradient with 90 degree angle with start and end color same as the stroke, center color same as background color. Please see the code:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<layer-list>
<item android:right="5dp" android:top="0dp">
<shape>
<corners android:radius="50dp" />
<gradient
android:angle="45"
android:startColor="#8008c3fa"
android:endColor="#8008c3fa"
android:type="linear"
/>
</shape>
</item>
<item android:bottom="5dp" android:left="6dp" android:right="10dp" android:top="5dp">
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<corners
android:radius="50dp"
/>
<gradient
android:angle="90"
android:centerX="50%"
android:centerColor="#color/trans_parent"
android:startColor="#8008c3fa"
android:endColor="#8008c3fa"
android:type="linear"
/>
<padding
android:left="0dp"
android:top="0dp"
android:right="0dp"
android:bottom="0dp"
/>
<size
android:width="270dp"
android:height="60dp"
/>
<stroke
android:width="2.5dp"
android:color="#08c3fa"
/>
</shape>
</item>
</layer-list>
</item>
</selector>
For the above xml, I got the below result:
Though the design and the result images look totally different, I think if we increase the center color height and keep a fadeout effect to the shadow, it can work. But I'm not able to do the same.
you can increase the center color height and keep a fadeout effect to the shadow by adding a nother item to the layer-list.
The first item makes the gradient for the upper bound, the rest is transparent and the second item makes the gradient for the lower bound the same way.
I added two more items to fill the left and the right semicircle.
I changed a few colours to enhance the effect but didnt trie too long, i think one could do alot more with more items and better colours :)

I know it has been a while but if anyone is still interested in this effect, here is a custom view library I made which was inspired by this question:
Glowing and Neon Button
It also has animated disable and enable methods as seen in the photo.
It's MIT Licensed, so do whatever you want with it. hope this helps someone.
If you want to have improved neon Buttons with a solid that has different gradients too. Take a look on this related post I answered. I used the suggested library from "#Mehran B" and combined it with a custom drawable and a transparent stroke to make it more modifiable. As you can see in the samples below the gradients from the solids and shadows are separated and thus more flexible:
I currently have the following drawable which creates a rectangle with rounded edges, a semi-transparent black background and transparent edges (in case I want to show them later):
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<color android:color="#android:color/transparent" />
</item>
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#50FFFFFF"/>
<stroke
android:width="5dip"
android:color="#android:color/transparent" />
<corners android:radius="30dp" />
</shape>
</item>
</layer-list>
My question is how could I modify this so that the edges of the rectangle's background fade, to give a softer appearance?
I did something like this for work once.
Just make a layer-list with multiple rectangle each with increasing opacity and padding
code below:
<?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="#03101010" />
<corners android:radius="24dp" />
</shape>
</item>
<item
android:bottom="4dp"
android:left="4dp"
android:right="4dp"
android:top="4dp">
<shape android:shape="rectangle">
<solid android:color="#06101010" />
<corners android:radius="20dp" />
</shape>
</item>
<item
android:bottom="8dp"
android:left="8dp"
android:right="8dp"
android:top="8dp">
<shape android:shape="rectangle">
<solid android:color="#09101010" />
<corners android:radius="16dp" />
</shape>
</item>
<item
android:bottom="12dp"
android:left="12dp"
android:right="12dp"
android:top="12dp">
<shape android:shape="rectangle">
<solid android:color="#12101010" />
<corners android:radius="12dp" />
</shape>
</item>
</layer-list>
The number of layers may vary depending on the color of your primary rectangle and the background.
I was wondering if it is possible to have multiple borders/"stroke" elements on a shape, or if I need to use an image (or a bunch of shapes covering each other). My code:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<gradient
android:endColor="#color/editTextBG"
android:startColor="#color/editTextBG"
android:angle="270" />
<stroke
android:width="1dp"
android:color="#color/editTextEdgeInner" />
<stroke
android:width="1dp"
android:color="#color/editTextEdgeCenter" />
<stroke
android:width="1dp"
android:color="#color/editTextEdgeOuter" />
<corners
android:radius="3dp" />
<padding
android:left="10dp"
android:top="10dp"
android:right="10dp"
android:bottom="10dp" />
</shape>
</item>
</selector>
I've tried just using the code, which didn't work, and giving the earlier strokes a bigger width (so that the later, if drawn over, would only color part). However, it seems the last stroke overrides the others?
A workaround for borders is to overlay elements:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<color android:color="#color/colorAccent"/>
</item>
<item android:top="8dp">
<color android:color="#color/colorPrimaryDark"/>
</item>
<item android:top="16dp">
<color android:color="#color/colorPrimary"/>
</item>
<item android:top="32dp" android:right="8dp">
<color android:color="#android:color/holo_red_dark"/>
</item>
</layer-list>
This is the result:
The first element in the layer-list from top to bottom is the background and every other is mounted on top.
<item>
<shape android:shape="rectangle">
<corners android:radius="8dp" />
<solid android:color="#color/colorWhite" />
<stroke
android:width="1dp"
android:color="#979797" />
</shape>
</item>
<item
android:bottom="5dp"
android:left="5dp"
android:right="5dp"
android:top="5dp">
<shape android:shape="rectangle">
<corners android:radius="4dp" />
<solid android:color="#ffd400" />
</shape>
</item>
How can I find the colour used for a default button's background, both when it is clicked and not. I've tried to use android.R.drawable.btn_default for not clicked, but this color is lighter then default on my tablet.
Then use custom color using selector eg customstyle.xml under drawable and using this as background for your button. Sample code its working fine for me.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape>
<solid
android:color="#f8f9fa" />
<stroke
android:width="1dp"
android:color="#d2d2d2" />
<corners
android:radius="1dp" />
</shape>
</item>
<item>
<shape>
<gradient
android:startColor="#f8f9fa"
android:endColor="#d2d2d2"
android:angle="270" />
<stroke
android:width="1dp"
android:color="#d2d2d2" />
<corners
android:radius="1dp" />
</shape>
</item>
</selector>
