WindowManager.LayoutParams（下）

本文參照自： http://developer.android.com/reference/android/view/WindowManager.LayoutParams.html BRIGHTNESS系列 該系列主要用于設定window的 brightness ( screenBrightness / buttonBrightness )。 我們可以通過 WindowManager.LayoutParams 的 screenBrightness / buttonBrightness 變量直接進行設定。 其中 screenBrightness 表示螢幕的b rightness ,而 buttonBrightness 表示一般按鍵和鍵盤按鍵的 brightness

float	BRIGHTNESS_OVERRIDE_FULL	Value for  screenBrightness  and  buttonBrightness indicating that the screen or button backlight brightness should be set to the hightest value  when this window is in front. 把brightness(screenBrightness/buttonBrightness)設定到最高值。
float	BRIGHTNESS_OVERRIDE_NONE	Default value for  screenBrightness  and  buttonBrightness  indicating that the brightness value is not overridden for this window and normal brightness policy should be used. 不對brightness(screenBrightness/buttonBrightness)重新進行設定，采用預設的普通值。
float	BRIGHTNESS_OVERRIDE_OFF	Value for  screenBrightness  and  buttonBrightness  indicating that the screen or button backlight brightness should be set to the lowest value when this window is in front. 把brightness(screenBrightness/buttonBrightness)設定到最低值。

changed系列 該系列主要用于  int copyFrom (WindowManager.LayoutParams o)函數中。 在函數中，首先将用參數中傳入的 WindowManager.LayoutParams的資訊複制到本 WindowManager.LayoutParams 中，然後傳回一個整數，以bite形式表示調用該函數後 WindowManager.LayoutParams的哪些資訊發送了變化

int	ALPHA_CHANGED	用于表示成員變量alpha是否被改變
int	ANIMATION_CHANGED	用于表示成員變量windowAnimations是否被改變
int	DIM_AMOUNT_CHANGED	用于表示成員變量dimAmount是否被改變
int	FLAGS_CHANGED	用于表示成員變量flags是否被改變
int	LAYOUT_CHANGED	用于表示layout是否被改變.這裡的layout是指以下變量所包含的資訊： width，height,x,y, verticalMargin，verticalWeight,horizontalMargin，horizontalWeight
int	SCREEN_BRIGHTNESS_CHANGED	用于表示brightness是否被改變. 這裡的brightness是指以下變量對應的資訊：screenBrightness，buttonBrightness
int	SCREEN_ORIENTATION_CHANGED	用于表示成員變量screenOrientation是否被改變
int	SOFT_INPUT_MODE_CHANGED	用于表示成員變量softInputMode是否被改變
int	TITLE_CHANGED	用于表示成員變量title是否被改變
int	TYPE_CHANGED	用于表示成員變量type是否被改變
int	FORMAT_CHANGED	Constant Value: 8 (0x00000008) 用于表示成員變量format是否被改變

成員變量 繼承于 ViewGroup.LayoutParams 的成員變量

public int	height	Information about how tall the view wants to be.
public  LayoutAnimationController.AnimationParameters	layoutAnimationParameters	Used to animate layouts.
public int	width	Information about how wide the view wants to be.

自身的成員變量

public static final  Creator< WindowManager.LayoutParams>	CREATOR
public float	alpha	An alpha value to apply to this entire window.
public float	buttonBrightness	This can be used to override the standard behavior of the button and keyboard backlights.
public float	dimAmount	When  FLAG_DIM_BEHIND  is set, this is the amount of dimming to apply.
public int	flags	Various behavioral options/flags.
public int	format	The desired bitmap format.
public int	gravity	Placement of window within the screen as per  Gravity .
public float	horizontalMargin	The horizontal margin, as a percentage of the container's width, between the container and the widget.
public float	horizontalWeight	Indicates how much of the extra space will be allocated horizontally to the view associated with these LayoutParams.
public int	memoryType	This field is deprecated. this is ignored
public  String	packageName	Name of the package owning this window.
public float	screenBrightness	This can be used to override the user's preferred brightness of the screen.
public int	screenOrientation	Specific orientation value for a window.
public int	softInputMode	Desired operating mode for any soft input area.
public int	systemUiVisibility	Control the visibility of the status bar.
public  IBinder	token	Identifier for this window.
public int	type	The general type of window.
public float	verticalMargin	The vertical margin, as a percentage of the container's height, between the container and the widget.
public float	verticalWeight	Indicates how much of the extra space will be allocated vertically to the view associated with these LayoutParams.
public int	windowAnimations	A style resource defining the animations to use for this window.
public int	x	X position for this window.
public int	y	Y position for this window.
