android状态栏操作的各种方式

    fun getStatusBarHeight(context: Context): Int {
        val resourceId = context.resources.getIdentifier("status_bar_height", "dimen", "android")
        if (resourceId > 0) {
            return context.resources.getDimensionPixelSize(resourceId)
        }
        return 0
    }

    fun setStatusBarTransparent(activity: Activity) {
        if (isFromM()) {
//            val decorView = activity.window.decorView
//            val option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
//            decorView.systemUiVisibility = option
            activity.window.statusBarColor = Color.TRANSPARENT
        }
    }

    fun setStatusBarBgColor(activity: Activity, @ColorInt color: Int) {
        if (isFromM()) {
//            val decorView = activity.window.decorView
//            val option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
//            decorView.systemUiVisibility = option
            activity.window.statusBarColor = color
        }
    }

    fun setStatusBarIconColor(activity: Activity, blackIcon: Boolean) {
        var option = 0;
        if (blackIcon) {
            option = View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR  //白底黑字
        } else {
            option = View.SYSTEM_UI_FLAG_VISIBLE;     //默认，黑底白字
        }
        activity.window.decorView.systemUiVisibility = option
    }

    fun setStatusBarFullScreen(activity: Activity, isFloat: Boolean) {
        val decorView = activity.window.decorView
        val option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
        decorView.systemUiVisibility = option
    }

    
        
        @color/white
        @color/white
        @color/white
        true  
    

 setSystemUiVisibility(int visibility)传入的实参类型如下：

1.View.SYSTEM_UI_FLAG_VISIBLE ：状态栏和Activity共存，Activity不全屏显示。也就是应用平常的显示画面

2.View.SYSTEM_UI_FLAG_FULLSCREEN ：Activity全屏显示，且状态栏被覆盖掉

3. View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN ：Activity全屏显示，但是状态栏不会被覆盖掉，而是正常显示，只是Activity顶端布   局会被覆盖住

4.View.INVISIBLE ： Activity全屏显示，隐藏状态栏
