Demonstrates how to identify and avoid line-length issues with TextView. The measure, or characters per line, of a block of text plays a key role in how comfortable it is to read (sometimes referred to as readability). A widely accepted optimal range for a text block's measure is between 45 and 75 characters. This code demonstrates two phases of…

seanKenkeremath / Android Lollipop Widget Tinting Guide
Last active November 17, 2023 12:40
How base colors in Lollipop apply to different UI elements
Unless specified otherwise, all of the below tinting applies to both Lollipop and pre-Lollipop using AppCompat v21. To use the support version of these attributes, remove the android namespace. For instance, "android:colorControlNormal" becomes "colorControlNormal". These attributes will be propagated to their corresponding attributes within the android namespace for devices running Lollipop. Any exceptions to this will be noted by including the "android:" prefix.
All Clickable Views:
-----------
* ripple effect (Lollipop only) -- "colorControlHighlight"
Status Bar:
------------
* background (Lollipop only) - "colorPrimaryDark"

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>
