### 使用案例（Kotlin） ###

//沉浸式实现
    StatusBarUtil.immersive(this)
    
    //填充View
    //id：控件id
    StatusBarUtil.setPaddingSmart(this, id)
    
    //状态栏字体颜色
    //true：黑色
    //false：白色
    StatusBarUtil.darkMode(this, false)
    
    //状态栏颜色
    //activity
    //color(状态栏颜色值)
    //alpha（透明度，取值范围 0.0f - 1.0f ）
    StatusBarUtil.darkMode(this, resources.getColor(R.color.color_00ff00), 0.5f)
