## HokoBlurDrawable
HokoBlurDrawable is an Android component which provides dynamic blur effect.
### 1. Introductions
- Function：
**Dynamic blur, real-time blurring of the background**。
- Features：
- Multiple algorithms: Box、Stack and Gaussian algorithms. Provide different blur effect；
- 🚀iOS-like dynamic backgroud blur: Compared to using RenderScript to process bitmaps, the component has better performance and effect.
### 2. Dynamic background blur
Dynamic Blur provides real-time background blurring of View and ViewGroup, not for Bitmap implementations. The component will blur the area where the View is located.
Add dependency
```groovy
implementation 'com.hoko:blur-drawable:0.0.1'
```
To add background blur to the View, just set the BlurDrawable to the View background.
```java
final BlurDrawable blurDrawable = new BlurDrawable();
View view = findViewById(R.id.test_view);
view.setBackgroundDrawable(blurDrawable);
```
Change the blur parameters：
```java
blurDrawable.mode(mode)
blurDrawable.radius(radius)
blurDrawable.sampleFactor(factor)
```
Add blur color mixture(OverlayColor)
```java
blurDrawable.mixColor(color)
blurDrawable.mixPercent(percent) //0 ~ 1.0
```
DISABLE/ENABLE background blur
```java
blurDrawable.disableBlur();
blurDrawable.enableBlur();
```
HokoBlur already contains three common ViewGroups that implement background blur, including BlurFrameLayout, BlurLinearLayout, and BlurRelativeLayout.
```java
// blur animation
ValueAnimator animator = ValueAnimator.ofInt(0, 20);
animator.setDuration(2000);
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
@Override
public void onAnimationUpdate(ValueAnimator animation) {
mFrameLayout.getBlurDrawable().setBlurRadius((Integer) animation.getAnimatedValue());
}
});
```
## 动态模糊组件HokoBlur
### 1. 描述
- 组件主要提供以下功能：
**动态模糊，对背景的实时模糊**。
- 组件主要的特性：
- 多种算法，包括Box、Stack和Gaussian算法，满足不同的模糊效果；
- 🚀类似iOS的动态背景模糊，相比使用RenderScript处理Bitmap的动态模糊方案，具有更好的效果和性能
### 2. 动态模糊
动态模糊提供了对View以及ViewGroup的实时背景模糊，并不是针对Bitmap的实现。组件将会对View所在区域进行模糊。
添加依赖
```groovy
implementation 'com.hoko:blur-drawable:0.0.1'
```
为View添加背景模糊，只需要将BlurDrawable设置为View背景即可。
```java
final BlurDrawable blurDrawable = new BlurDrawable();
View view = findViewById(R.id.test_view);
view.setBackgroundDrawable(blurDrawable);
```
模糊参数的调整，可以这样操作：
```java
blurDrawable.mode(mode)
blurDrawable.radius(radius)
blurDrawable.sampleFactor(factor)
```
为模糊效果添加混合蒙版(OverlayColor)
```java
blurDrawable.mixColor(color)
blurDrawable.mixPercent(percent) //0 ~ 1.0
```
禁用/开启背景模糊
```java
blurDrawable.disableBlur();
blurDrawable.enableBlur();
```
组件已包含实现背景模糊的三种常用ViewGroup，包括BlurFrameLayout、BlurLinearLayout和BlurRelativeLayout。
使用示例：
```java
// 模糊动画
ValueAnimator animator = ValueAnimator.ofInt(0, 20);
animator.setDuration(2000);
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
@Override
public void onAnimationUpdate(ValueAnimator animation) {
mFrameLayout.getBlurDrawable().setBlurRadius((Integer) animation.getAnimatedValue());
}
});
```
