How to set transparency with hex value ?

For example, you want to set 40% alpha transparence to #000000 (black color), you need to add 66 like this #66000000.

With the new theming in AppCompat, a lot of assets are tinted automatically for you via theme attributes. That has often led me to wonder "where the hell did this color come from?" You can replace your normal theme with this debug theme to help figure out the source of that color.
<!-- You can change the parent around to whatever you normally use -->
<style name="DebugColors" parent="Theme.AppCompat">
<!-- System colors -->
<item name="android:windowBackground">@color/__debugWindowBackground</item>
<item name="android:colorPressedHighlight">#FF4400</item>
<item name="android:colorLongPressedHighlight">#FF0044</item>
<item name="android:colorFocusedHighlight">#44FF00</item>
<item name="android:colorActivatedHighlight">#00FF44</item>
