# Gradle Dependency
#### Repository
Add this in your root `build.gradle` file (**not** your module `build.gradle` file):
```gradle
allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}
```
#### Dependency
Add this to your module's `build.gradle` file:
```gradle
dependencies {
...
compile 'com.github.jd-alexander:LikeButton:0.2.3'
}
}
```
---
# Basic Usage
#### Like Button XML
To use this like button in your layout simply copy and paste the xml below. This provides the default heart button.
```xml
```
#### Attributes
There are several other attributes that can be used to configure the button's behaviour and appearance. They are shown below and will be explained in the sections that follow long with their java counterparts.
```xml
```
---
# Button State
To set the inital liked state of the button you simply use the setLiked functionality via XML or Java. This will show the button in the liked state with the drawable that you selected.
#### XML
```
app:liked="true"
```
#### Java
```java
likeButton.setLiked(true);
```
You can also set if the button is to be enabled or disabled. Once disabled, the animation, listener or any other functionality of the button won't be triggered.
#### XML
```
app:is_enabled="false"
```
#### Java
```java
likeButton.setEnabled(false);
```
---
# Like Event Listener
To listen to events from your like button, simply implement the listener that's triggered once the button is tapped.
```java
likeButton.setOnLikeListener(new OnLikeListener() {
@Override
public void liked(LikeButton likeButton) {
}
@Override
public void unLiked(LikeButton likeButton) {
}
});
```
---
# Icon Types
The libary is bundled with three icons that you can use. A heart,thumb and a star.
#### XML
To set the respective icon via xml simply use the word in the icon type attribute.
```
app:icon_type="heart"
```
#### Java
If you would like to set the icon via Java then simply call the set icon method on the button.
```java
likeButton.setIcon(IconType.Star);
```
---
# Icon Size
#### XML
To set the icon size via xml simply use this attribute
```xml
app:icon_size="20dp"
```
#### Java
If you are doing it programmatically you can set it with either the method for pixels or dp.
```java
likeButton.setIconSizePx(40);
likeButton.setIconSizeDp(20);
```
Note, it's very important that the size of the button is set even if you are planning to use custom drawables as described below as the library uses this value to determine the width and height of the effects that occur when the button is tapped.
---
# Custom Icons
#### XML
In order to use custom icons instead of the ones bundled with the library you simply set the drawables that represent the liked and unliked state of the button.
```
app:like_drawable="@drawable/thumb_on"
app:unlike_drawable="@drawable/thumb_off"
```
#### Java
```java
likeButton.setLikeDrawable(heart_on);
likeButton.setUnlikeDrawable(heart_off);
likeButton.setUnlikeDrawableRes(R.drawable.heart_off);
likeButton.setLikeDrawableRes(R.drawable.heart_on);
```
---
# Circle Color Config
If you watch the animation closely you will notice that there's a circle that begins from the center of the icon and and then it animates away from the center before the exploding dots animate. These colours can be changed to suit the theme of your icon.
#### XML
```
app:circle_start_color="@color/colorPrimary"
app:circle_end_color="@color/colorAccent"
```
#### Java
```java
likeButton.setCircleEndColorRes(R.color.colorAccent);
likeButton.setCircleEndColorRes(R.color.colorPrimary);
```
---
# Dots Color Config
The dots that represent the outer animation can be coloured also.
#### XML
```
app:dots_primary_color="@color/colorAccent"
app:dots_secondary_color="@color/colorPrimary"
```
#### Java
```
likeButton.setExplodingDotColorsRes(R.color.colorPrimary,R.color.colorAccent);
```
---
# Animation Size
To change the size of the dots that also contributes to the size of the overall like button view you can use the animation scale factor attribute via XML or it's Java equivalent
#### XML
```
app:anim_scale_factor="2.5"
```
#### Java
```
likeButton.setAnimationScaleFactor(2);
```
