BRIGHTNESS系列
该系列主要用于设置window的
brightness
(
screenBrightness
/
buttonBrightness
)。
我们可以通过
WindowManager.LayoutParams
的
screenBrightness
/
buttonBrightness
变量直接进行设置。
其中
screenBrightness
表示屏幕的b
rightness
,而
buttonBrightness
表示一般按键和键盘按键的
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)设置到最高值。 |
| 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. 不对brightness(screenBrightness/buttonBrightness)重新进行设置，采用默认的普通值。 |
| 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)设置到最低值。 |
changed系列
该系列主要用于
int copyFrom (WindowManager.LayoutParams o)函数中。
在函数中，首先将用参数中传入的
WindowManager.LayoutParams的信息复制到本
WindowManager.LayoutParams
中，然后返回一个整数，以bite形式表示调用该函数后
WindowManager.LayoutParams的哪些信息发送了变化
| int | ALPHA_CHANGED | 用于表示成员变量alpha是否被改变 |
| int | ANIMATION_CHANGED | 用于表示成员变量windowAnimations是否被改变 |
| int | DIM_AMOUNT_CHANGED | 用于表示成员变量dimAmount是否被改变 |
| int | FLAGS_CHANGED | 用于表示成员变量flags是否被改变 |
| int | LAYOUT_CHANGED | 用于表示layout是否被改变.这里的layout是指以下变量所包含的信息： width，height,x,y, verticalMargin，verticalWeight,horizontalMargin，horizontalWeight |
| int | SCREEN_BRIGHTNESS_CHANGED | 用于表示brightness是否被改变. 这里的brightness是指以下变量对应的信息：screenBrightness，buttonBrightness |
| int | SCREEN_ORIENTATION_CHANGED | 用于表示成员变量screenOrientation是否被改变 |
| int | SOFT_INPUT_MODE_CHANGED | 用于表示成员变量softInputMode是否被改变 |
| int | TITLE_CHANGED | 用于表示成员变量title是否被改变 |
| int | TYPE_CHANGED | 用于表示成员变量type是否被改变 |
| int | FORMAT_CHANGED | Constant Value: 8 (0x00000008) 用于表示成员变量format是否被改变 |
成员变量
继承于
ViewGroup.LayoutParams
的成员变量
| 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. |
自身的成员变量
| 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. |
成员函数

| final int | copyFrom(WindowManager.LayoutParams o) |
| String | debug(String output)
Returns a String representation of this set of layout parameters. |
| int | describeContents()
