# UI Tools Library for Android

[![Build Status](https://travis-ci.org/Scalified/uitools.svg?branch=master)](https://travis-ci.org/Scalified/uitools)
[![Maven Central](https://img.shields.io/maven-central/v/com.scalified/uitools.svg)](http://search.maven.org/#search|gav|1|g%3A%22com.scalified%22%20AND%20a%3A%22uitools%22)

## Description

**UI Tools** Library contains lots of useful methods for working with **Android User Interface API**

## Requirements

The Library requires **Android SDK version 9 (Gingerbread)** and higher

## Gradle Dependency

```java
dependencies {
	compile 'com.scalified:uitools:1.1.2'
}
```

## Activity Stream

[**Full ChangeLog**](https://github.com/Scalified/uitools/blob/master/CHANGELOG.md)

### 1.1.2 - *current*

1. Changed the standard Android logging API to **SLF4J Logging API**

### 1.0.0 - *previous*

1. The first release! Everything is new.

### Features in the next versions:

***TBD***

## Usage

### IdGenerator

**IdGenerator** is responsible for views id generation.

To generate the view id:

```java
View view;
// ... view initialization code goes here

view.setId(IdGenerator.next());
```

### ColorModifier

**ColorModifier** contains utility methods for color modification.

To modify the color exposure:

```java
int color = Color.DKGRAY;

// Darken the color:
int darkerColor = ColorModifier.modifyExposure(color, 0.8f);

// Lighten the color:
int lighterColor = ColorModifier.modifyExposure(color, 1.5f);
```

### DensityConverter

**DensityConverter** contains utility methods for density values conversion based on the current device's display metrics.

To convert the density-independent pixels into density-dependent ones and vice versa:

```java
float pixels = 100.0f;

// Convert to real pixels:
float realPixels = DensityConverter.dpToPx(getContext(), pixels)

// Convert to density-independent pixels:
float densityPixels = DensityConverter.pxToDp(getContext(), pixels);
```

## Logging

To enable logging:

1. Add the following dependency:

```java
	dependencies {
		compile 'com.github.tony19:logback-android-classic:1.1.1-3'
	}
	```
2. Create the **logback.xml** file in the **src/main/assets** with the sample configuration:

```xml
	<?xml version="1.0" encoding="UTF-8"?>
	<configuration>
		<appender name="LOGCAT" class="ch.qos.logback.classic.android.LogcatAppender">
			<tagEncoder>
				<pattern>%logger{0}</pattern>
			</tagEncoder>
			<encoder>
				<pattern>%d{HH:mm:ss.SSS} [%thread] [%logger{0}] - %msg%n</pattern>
			</encoder>
		</appender>
	
		<root level="TRACE" additivity="false">
			<appender-ref ref="LOGCAT" />
		</root>
	</configuration>
	```
	> You may wish to configure different appenders with different log levels for packages, classes etc.
	
	> More information about **LOGBack** can be found @ [LOGBack Project Site](http://logback.qos.ch)

3. Add the following **InvalidPackage** ignore rule into **lint.xml** file (located @ the root of the project):

```xml
	<issue id="InvalidPackage" >
    	<ignore path="**/logback-android-core/*" />
    </issue>
	```
