http://developer./reference/android/view/WindowManager.LayoutParams.htmlBRIGHTNESS系列
該系列主要用于設(shè)置window的brightness(screenBrightness/buttonBrightness)。我們可以通過WindowManager.LayoutParams的screenBrightness/buttonBrightness變量直接進(jìn)行設(shè)置。
其中screenBrightness表示屏幕的brightness,而buttonBrightness表示一般按鍵和鍵盤按鍵的brightness
changed系列
在函數(shù)中，首先將用參數(shù)中傳入的WindowManager.LayoutParams的信息復(fù)制到本WindowManager.LayoutParams中，然后返回一個(gè)整數(shù)，以bite形式表示調(diào)用該函數(shù)后WindowManager.LayoutParams的哪些信息發(fā)送了變化
