# AndroidStyling-LintRules 

[![Android Arsenal](https://img.shields.io/badge/Android%20Arsenal-AndroidStyling--LintRules-brightgreen.svg?style=flat)](https://android-arsenal.com/details/1/8238)

A set of lint rules to prevent us from the temptation of using HEX values or direct color resources instead of attributes, when creating our

 layouts either by xml or programmatically.  

To refresh your knowledge about theming colors: [Material Guidelines](https://material.io/develop/android/theming/color/). 

## Installation

AndroidStyling-LintRules is distributed through [Maven Central](https://search.maven.org/artifact/com.github.guilhe/styling-lint) and [Jitpack](https://jitpack.io/#GuilhE/AndroidStyling-LintRules).

```groovy

implementation 'com.github.guilhe:styling-lint:${LATEST_VERSION}'

```

[![Maven Central](https://img.shields.io/maven-central/v/com.github.guilhe/styling-lint.svg)](https://search.maven.org/search?q=g:com.github.guilhe%20AND%20styling-lint)

## Usage

Well this is easy, your styles and layouts should always use attributes to get the color from the corresponding theme.  

Therefore, in situations like:

```xml

```

You'll get a warning advising you to change it:  



This rules are not exclusive for layouts:

```java

getColor(R.color.colorPrimary)

```

You'll also get a warning advising you to change it:  



In code situations, getting a color from a theme is not that trivial and it involves a bit of boilerplate code.  

For that reason, [ResourcesProvider-ktx](https://github.com/GuilhE/ResourcesProvider-ktx) may come in hand. It's a helper class to provide

 resources and it has ["themes support"](https://github.com/GuilhE/ResourcesProvider-ktx#themes):

   

```java

.setBackgroundColor(resourcesProvider.colorRes(R.attr.colorPrimary, R.style.App_Style_A)

```
